ITEM 1.

BUSINESS.

Overview

Retina Division

Until recently, the Company's Retina division was in the business of developing and commercializing a treatment for dry age-related macular degeneration, or Dry AMD. Age-related macular degeneration, or AMD, is the leading cause of late onset visual impairment and legal blindness in people over the age of 50 in the United States and other Western industrialized societies.

We believe that Dry AMD, the most common form of the disease, afflicts approximately 13.0 to 13.5 million people in the United States, representing approximately 85% to 90% of all AMD cases. Although the exact cause of AMD is not known, researchers have identified several factors that are associated with AMD, including poor microcirculation and the gradual build-up of cellular waste material in the retina. We believe that improved microcirculation increases the supply of oxygen and nutrients to the compromised retina and facilitates the removal of cellular waste material from the retina. We believe that a treatment that improves microcirculation in the retina can help to enhance the metabolic efficiency of the retina and the removal of waste material and thereby aid in the treatment of Dry AMD. We believe there is a significant opportunity for such a treatment.

Our product for Dry AMD, the RHEO™ System, is designed to improve microcirculation in the eye by filtering high molecular weight proteins and other macromolecules from the patient’s plasma. The RHEO™ System is used to perform the Rheopheresis™ procedure, which we refer to under our trade name RHEO™ Therapy. The Rheopheresis™ procedure is a blood filtration process that selectively removes molecules from plasma. The RHEO™ System consists of the OctoNova Pump and a disposable treatment set, containing two filters, through which the patient’s blood circulates. We believe that the RHEO™ System is the only Dry AMD treatment to target what we believe to be the underlying cause of AMD rather than its symptoms and that, based on early data, appeared to demonstrate improved vision in some patients. The only currently accepted treatment option for persons with advanced cases of Dry AMD are over-the-counter vitamins, antioxidants and zinc supplements that can reduce the five-year risk of conversion to Wet AMD, the other form of the disease, by approximately 25%.

We conducted a pivotal clinical trial, called MIRA-1, or Multicenter Investigation of Rheopheresis for AMD, which, if successful, was expected to support our application to the U.S. Food and Drug Administration, or FDA, to obtain approval to market the RHEO™ System in the United States. On February 3, 2006, we announced that, based on a preliminary analysis of the data from MIRA-1, MIRA-1 did not meet its primary efficacy endpoint as it did not demonstrate a statistically significant difference in the mean change of Best Spectacle-Corrected Visual Acuity applying the Early Treatment Diabetic Retinopathy Scale, or ETDRS BCVA, between the treated and placebo groups in MIRA-1 at 12 months post-baseline. As expected, the treated group demonstrated a positive result. An anomalous response of the control group is the principal reason why the primary efficacy endpoint was not met. There were subgroups that did demonstrate statistical significance in their mean change of ETDRS BCVA versus control.

Subsequent to the February 3, 2006 announcement, the Company completed an in-depth analysis of the MIRA-1 study data identifying subjects that were included in the intent-to-treat, or ITT, population but who deviated from the MIRA-1 protocol as well as those patients who had documented losses or gains in vision for reasons not related to retinal disease such as cataracts. Those subjects in the ITT population who met the protocol requirements, and who did not exhibit ophthalmic changes unrelated to retinal disease, comprised the modified per-protocol population.

In light of the MIRA-1 study results, we also re-evaluated our Pre-Market Approval Application, or PMA, submission strategy and then met with representatives of the FDA, on June 8, 2006 in order to discuss the impact on our PMA submission strategy of the MIRA-1 study results. In light of MIRA-1’s failure to meet its primary efficacy endpoint, the FDA advised us that it would require an additional study of the RHEO™ System to be performed.

On January 29, 2007, the Company announced that it had obtained Investigational Device Exemption clearance from the FDA to commence the new pivotal clinical trial of the RHEO™ System, called RHEO-AMD, or Safety and Effectiveness in a Multi-center, Randomized, Sham-controlled Investigation for Dry, Non-exudative Age-Related Macular Degeneration (AMD) Using Rheopheresis.

However, on November 1, 2007, the Company announced the indefinite suspension of its RHEO™ System clinical development program. This decision was made following a comprehensive review of the respective costs and development timelines associated with the products in the Company's portfolio and in light of the Company's financial position. Between January 29, 2007 and November 1, 2007, the Company had prepared the RHEO-AMD protocol and had been putting into place all of the resources required for the conduct for the RHEO-AMD study, including the securing of clinical trial site commitments. The Company is in the process of winding down the RHEO-AMD study as there is no reasonable prospect that the RHEO™ System clinical development program will be relaunched in the foreseeable future. Subsequent to our fiscal 2007 year-end, as of February 25, 2008, we have terminated our relationship with Asahi Kasei Kuraray Medical Co., Ltd. (formerly Asahi Kasei Medical Co., Ltd.), or Asahi Medical. Asahi Medical manufactures, and supplied us with, the Rheofilter filter and the Plasmaflo filter, both of which are key components of the RHEO™ System. We also are engaged in discussions with Diamed Medizintechnik GmbH, or Diamed, and MeSys GmbH, or MeSys, regarding the termination of our relationship with each of them. Diamed is the designer, and MeSys is the manufacturer, of the OctoNova pump, another key component of the RHEO™ System.

Glaucoma Division

The SOLX Glaucoma System is a next-generation glaucoma treatment platform designed to reduce intra-ocular pressure, or IOP, without a bleb (which is a surgically created flap that serves as a drainage pocket underneath the surface of the eye), thus avoiding its related complications. The SOLX Glaucoma System consists of the SOLX 790 Laser, a titanium sapphire laser used in laser trabeculoplasty procedures, and the SOLX Gold Shunt, a 24-karat gold, ultra-thin drainage device designed to bridge the anterior chamber and the suprachoroidal space in the eye, using the pressure differential that exists naturally in the eye in order to reduce IOP.

The consideration for the purchase and sale of all of the issued and outstanding shares of the capital stock of SOLX consisted of: (i) on December 19, 2007, the closing date of the sale, the assumption by Solx Acquisition of all of the liabilities of OccuLogix, as they related to SOLX’s business, incurred on or after December 1, 2007, and OccuLogix’s obligation to make a $5,000,000 payment to the former stockholders of SOLX due on September 1, 2008 in satisfaction of the outstanding balance of the purchase price of SOLX; (ii) on or prior to February 15, 2008, the payment by Solx Acquisition of all of the expenses that OccuLogix had paid to the closing date, as they related to SOLX’s business during the period commencing on December 1, 2007; (iii) during the period commencing on the closing date and ending on the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 3% of the worldwide net sales of the SOLX 790 Laser and the SOLX Gold Shunt, including next-generation or future models or versions of these products; and (iv) following the date on which Solx achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 5% of the worldwide net sales of these products. In order to secure the obligation of Solx Acquisition to make these royalty payments, SOLX granted to OccuLogix a subordinated security interest in certain of its intellectual property. In connection with the sale of SOLX, those employees of the Company, whose roles and responsibilities related mainly to SOLX’s business, ceased to be employees of the Company and became employees of Solx Acquisition or SOLX.

Prior to the sale of SOLX, we had been in the process of training and certifying physicians in the use of the SOLX Gold Shunt, for commercial purposes, in various European and Asian jurisdictions, including Spain, Italy, Germany, Poland, France, the United Kingdom and Thailand. In addition, in order to establish and maintain a reliable distribution network for SOLX’s products, we had been continuing to maintain our relationships with distributors in France, Germany, Spain, the United Kingdom and Canada and had been engaged in pursuing relationships with other distributors in Europe.

Both the SOLX 790 Laser and the SOLX Gold Shunt are currently the subject of randomized, multi-center clinical trials, the purposes of which are to demonstrate equivalency to the argon laser, in the case of the SOLX 790 Laser, and to the Ahmed Glaucoma Valve manufactured by New World Medical, Inc., in the case of the SOLX Gold Shunt. The results of these clinical trials will be used in support of applications to the FDA for a 510(k) clearance for each of the SOLX 790 Laser and the SOLX Gold Shunt, the receipt of which, if any, will enable the marketing and sale of these products in the United States.

The SOLX 790 Laser received CE Mark approval in December 2004, and the SOLX Gold Shunt received CE Mark approval in October 2005. The SOLX 790 Laser has a Health Canada license, and, prior to the sale of SOLX, we had been seeking the corresponding approval for the SOLX Gold Shunt.

OcuSense, Inc.

As part of its accelerated diversification plans, on November 30, 2006, OccuLogix acquired 50.1% of the capital stock, on a fully diluted basis, 57.62% on an issued and outstanding basis, of OcuSense, Inc., or OcuSense, a San Diego-based company that is in the process of developing technologies that will enable eye care practitioners to test, at the point-of-care, for highly sensitive and specific biomarkers using nanoliters of tear film.

OcuSense’s first product, which is currently under development, is a hand-held tear film test for the measurement of osmolarity, a quantitative and highly specific biomarker that has shown to correlate with dry eye disease, or DED, The test is known as the TearLab™ test for DED. The anticipated innovation of the TearLab™ test for DED will be its ability to measure precisely and rapidly certain biomarkers in nanoliter volumes of tear samples, using inexpensive hardware. Historically, eye care researchers have relied on expensive instruments to perform tear biomarker analysis. In addition to their cost, these conventional systems are slow, highly variable in their measurement readings and not categorized as waived by the FDA under regulations promulgated under the Clinical Laboratory Improvement Amendments, or CLIA.

The TearLab™ test for DED will require the development of the following three components: (1) the TearLab™ disposable, which is a single-use microfluidic labcard; (2) the TearLab™ pen, which is a hand-held device that interfaces with the TearLab™ disposable; and (3) the TearLab™ reader, which is a small desktop unit that allows for the docking of the TearLab™ disposable and the TearLab™ pen and provides a quantitative reading for the operator. OcuSense is currently engaged in industrial, electrical and software design efforts for the three components of the TearLab™ test for DED and, to these ends, is working with two engineering partners, both based in Melbourne, Australia, one of which is a leader in biomedical instrument development and the other of which is a leader in customized microfluidics.

OcuSense’s objective is to complete product development of the TearLab™ test for DED during the first half of 2008. Following the completion of product development and subsequent clinical trials, OcuSense intends to seek a 510(k) clearance and a CLIA waiver from the FDA for the TearLab™ test for DED. Currently, it anticipates seeking the 510(k) clearance during the latter half of 2008 and the CLIA waiver during the latter half of 2009. In addition, OcuSense intends to seek CE Mark approval for the TearLab™ test for DED during the latter half of 2008.

OccuLogix acquired its 50.1% ownership stake, on a fully diluted basis, 57.62% on an issued and outstanding basis, in OcuSense for an aggregate purchase price of up to $8,000,000. Pursuant to the Series A Preferred Stock Purchase Agreement, dated as of November 30, 2006, by and among OcuSense and the Company (which agreement was amended subsequently on October 29, 2007), or the OcuSense Stock Purchase Agreement, the Company purchased 1,754,589 shares of OcuSense’s Series A Preferred Stock, par value $0.001 per share. The Company paid $2,000,000 of the purchase price on the closing of the purchase and made another $2,000,000 payment on January 3, 2007. A third $2,000,000 payment was made in June 2007 upon the attainment by OcuSense of the first of two pre-defined milestones, and the last $2,000,000 installment of the purchase price will become due and payable upon the attainment by OcuSense of the second of these two pre-defined milestones, being the successful production and testing of Beta Lab Cards for Osmolarity and the Beta Reader for Osmolarity, or the TearLab™ disposable and the TearLab™ reader, respectively. OcuSense attained this second milestone at the end of the first quarter of 2008.

The OcuSense Stock Purchase Agreement provides for an ability on the part of the Company to increase its ownership interest in OcuSense for nominal consideration if OcuSense fails to meet certain other milestones by specified dates. In addition, pursuant to the OcuSense Stock Purchase Agreement, the Company has agreed to purchase $3,000,000 of shares of OcuSense’s Series B Preferred Stock upon OcuSense’s receipt from the FDA, if any, of 510(k) clearance for the TearLab™ test for DED and to purchase another $3,000,000 of shares of OcuSense’s Series B Preferred Stock upon OcuSense’s receipt from the FDA, if any, of a CLIA waiver for the TearLab™ test for DED.

Current Situation

On October 9, 2007, we announced that the Company's Board of Directors, or the Board, had authorized management and our advisors to explore the full range of strategic alternatives available to enhance stockholder value. These alternatives may include, but are not limited to, the raising of capital through the sale of securities, one or more strategic alliances and the combination, sale or merger of all or part of OccuLogix. In making the announcement, the Company stated that there can be no assurance that the exploration of strategic alternatives will result in a transaction. To date, we have not disclosed, nor do we intend to disclose, developments with respect to our exploration of strategic alternatives unless and until the Board, has approved a specific transaction.

For some time prior to the October 9, 2007 announcement, the Company had been seeking to raise additional capital, with the objective of securing funding sufficient to sustain its operations as it has been clear that, unless we were able to raise additional capital, the Company would not have had sufficient cash to support its operations beyond early 2008. The Board’s decisions to suspend the Company's RHEO™ System clinical development program and to dispose of SOLX were made and implemented in order to conserve as much cash as possible while the Company continues its capital-raising efforts.

On January 9, 2008, we announced the departure, or pending departure, of seven members of our executive team and, commencing on February 1, 2008, a 50% reduction in the salary of each of Elias Vamvakas, our Chairman and Chief Executive Officer, and Tom Reeves, our President and Chief Operating Officer. By January 31, 2008, a total of 12 non-executive employees of the Company left the Company's employment.

On February 19, 2008, we announced that the Company secured a bridge loan in an aggregate principal amount of $3,000,000 from a number of private parties. The loan bears interest at a rate of 12% per annum and has a 180-day term, which may be extended to 270 days under certain circumstances. The repayment of the loan is secured by a pledge by the Company of its shares of the capital stock of OcuSense.

Under the terms of the loan agreement, the Company has two pre-payment options available to it, should it decide to not wait until the maturity date to repay the loan. Under the first pre-payment option, the Company may repay the loan in full by paying the lenders, in cash, the amount of outstanding principal and accrued interest and issuing to the lenders five-year warrants in an aggregate amount equal to approximately 19.9% of the issued and outstanding shares of the Company's common stock (but not to exceed 20% of the issued and outstanding shares of the Company's common stock). The warrants would be exercisable into shares of the Company's common stock at an exercise price of $0.10 per share and would not become exercisable until the 180th day following their issuance. Under the second pre-payment option, provided that the Company has closed a private placement of shares of its common stock for aggregate gross proceeds of at least $4,000,000, the Company may repay the loan in full by issuing to the lenders shares of its common stock, in an aggregate amount equal to the amount of outstanding principal and accrued interest, at a 15% discount to the price paid by the private placement investors. Any exercise by the Company of the second pre-payment option would be subject to stockholder and regulatory approval.

Currently, we anticipate that the net proceeds of the loan, together with the Company's other cash and cash-equivalents, will be sufficient to sustain the Company's operations only until approximately the end of April 2008 (assuming that the outstanding obligation of OccuLogix to pay $2,000,000 to OcuSense becomes due and payable prior to the end of April 2008).

Our History and Major Relationships

Shortly after our inception, we began commercialization of therapeutic apheresis by opening a therapeutic apheresis center in Florida. This site generated revenues of $900,200 and $1,277,800 for the years ended June 30, 1999 and 1998, respectively. The therapeutic apheresis center was closed in 1999 pursuant to a directive issued by the FDA. After obtaining an FDA investigational device exemption in 1999, we initiated the MIRA-1 pivotal clinical trial to support an application to the FDA for approval to market the RHEO™ System and completed this trial in 2005.

Relationship with TLC Vision Corporation

TLC Vision Corporation, or TLC Vision, beneficially owns approximately 32.8% of our outstanding common stock, or 28.9% on a fully diluted basis. Elias Vamvakas, formerly a director of TLC Vision and its past Chairman and CEO, became our Chairman in 2003 and is also our CEO. In addition, one of our other directors, Richard L. Lindstrom, is also a director of TLC Vision. One of our other directors, Thomas N. Davidson, also was a director of TLC Vision until December 2007. Mr. Vamvakas beneficially owns 1,041,795 common shares of TLC Vision, representing approximately 2.08% of TLC Vision’s outstanding shares. Mr. Davidson beneficially owns 67,127 common shares of TLC Vision, representing approximately 0.14% of TLC Vision’s outstanding shares, and Dr. Lindstrom beneficially owns 29,500 common shares of TLC Vision, representing approximately 0.06% of TLC Vision’s outstanding shares.

On December 8, 2004, we purchased TLC Vision’s 50% interest in OccuLogix, L.P. in exchange for which we issued 19,070,234 shares of our common stock to TLC Vision. This resulted in OccuLogix, L.P. becoming our wholly-owned subsidiary. Accordingly, 100% of the results of OccuLogix, L.P.’s operations are included in the consolidated financial statements since that date. We licensed to OccuLogix, L.P. all of the distribution and marketing rights for the RHEO™ System for ophthalmic indications to which we are entitled. Prior to the acquisition, our only profit stream had come from our share of OccuLogix, L.P.’s earnings. Our acquisition of TLC Vision’s 50% ownership interest in OccuLogix, L.P. transferred the earnings potential for sales of the RHEO™ System entirely to us.

As part of the formation of OccuLogix, L.P. in July 2002, we licensed certain patent rights, trademark rights and know-how rights to OccuLogix, L.P. We also provided OccuLogix, L.P. with licenses to our in-house software as well as sublicensing software that we have licensed from TLC Vision. TLC Vision agreed to provide OccuLogix, L.P., upon request, with $200,000 in funding at an annual interest rate equal to the Bank of America prime rate of interest on the date the loan is made, plus two percent. As at December 8, 2004, Occulogix, L.P. had not requested funding from TLC Vision.

On December 31, 2005, OccuLogix, L.P. transferred all of its assets and liabilities, including the licensed patent, trademark and know-how rights and the licensed distribution and marketing rights for the RHEO™ System, to our then newly incorporated subsidiary, OccuLogix Canada Corp. We completed the wind-up of OccuLogix, L.P. on February 6, 2006. Whatever residual value exists with respect to the RHEO™ System resides solely in OccuLogix Canada Corp.

On June 22, 2007, TLC Vision sold 1,904,762 shares of OccuLogix’s common stock to JEGC OCC Corp., or JEGC. JEGC is owned by Greybrook Corporation, a private equity firm controlled by Mr. Vamvakas, and by Jefferson Equicorp Ltd., a private equity firm controlled by David Folk, Managing General Partner of Jefferson Partners.

Other Major Relationships

The components of the RHEO™ System were developed by our suppliers, Diamed and Asahi Medical.

Prior to the Company's acquisition of SOLX, Doug P. Adams served as the President and Chief Executive Officer of SOLX and was a significant stockholder of SOLX. Between September 1, 2006, the closing date of the acquisition, and December 19, 2007, the closing date of OccuLogix’s sale of SOLX to Solx Acquisition, Mr. Adams served as an executive officer of the OccuLogix. OccuLogix paid Mr. Adams a total of $1,615,930 and issued to him 1,309,329 shares of our common stock in consideration of his proportionate share of the purchase price of SOLX. Until the assumption, on December 19, 2007, by Solx Acquisition of OccuLogix’s obligation to pay $5,000,000 to the former stockholders of SOLX on September 1, 2008 in satisfaction of the outstanding balance of the purchase price of SOLX, Mr. Adams was owed $1,024,263 by OccuLogix in consideration of his proportionate share of the outstanding balance of the purchase price of SOLX.

In addition, in connection with the Company's acquisition of SOLX, OccuLogix paid Peter M. Adams, Doug P. Adams’ brother, a total of $371,095 and issued to him and his spouse an aggregate of 300,452 shares of our common stock in consideration of his proportionate share of the purchase price of SOLX. Until the assumption, on December 19, 2007, by Solx Acquisition of OccuLogix’s obligation to pay $5,000,000 to the former stockholders of SOLX on September 1, 2008 in satisfaction of the outstanding balance of the purchase price of SOLX, OccuLogix owed Mr. Adams $236,917 in consideration of his proportionate share of the outstanding balance of the purchase price of SOLX.

On November 30, 2006, Mr. Vamvakas agreed to provide the Company with a standby commitment to purchase convertible debentures of the Company in an aggregate maximum principal amount of up to $8 million. When the Company raised gross proceeds in the amount of $10,016,000 on February 6, 2007 in a private placement of shares of its common stock and warrants, the commitment amount under Mr. Vamvakas’ standby commitment was reduced to zero, thus effectively terminating the standby commitment. No portion of the standby commitment was ever drawn down by the Company, and the Company has paid Mr. Vamvakas a total of $29,808 in commitment fees.

On December 19, 2007, we sold SOLX to Solx Acquisition, Inc., a company wholly owned by Doug P. Adams. The consideration for the purchase and sale of all of the issued and outstanding shares of the capital stock of SOLX consisted of: (i) on December 19, 2007, the closing date of the sale, the assumption by Solx Acquisition of all of the liabilities of OccuLogix, as they related to SOLX’s business, incurred on or after December 1, 2007, and OccuLogix’s obligation to make a $5,000,000 payment to the former stockholders of SOLX due on September 1, 2008 in satisfaction of the outstanding balance of the purchase price of SOLX; (ii) on or prior to February 15, 2008, the payment by Solx Acquisition of all of the expenses that OccuLogix had paid to the closing date, as they related to SOLX’s business during the period commencing on December 1, 2007; (iii) during the period commencing on the closing date and ending on the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 3% of the worldwide net sales of the SOLX 790 Laser and the SOLX Gold Shunt, including next-generation or future models or versions of these products; and (iv) following the date on which Solx achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 5% of the worldwide net sales of these products. In order to secure the obligation of Solx Acquisition to make these royalty payments, SOLX granted to OccuLogix a subordinated security interest in certain of its intellectual property.

Marchant Securities Inc., or Marchant, a firm indirectly beneficially owned as to approximately 32% by Mr. Vamvakas and members of his family, introduced the Company to the lenders of the $3,000,000 aggregate principal amount bridge loan that the Company secured and announced on February 19, 2008. For such service, Marchant will be paid a commission of $180,000, being 6% of the aggregate principal amount of the loan. Subject to obtaining any and all requisite stockholder and regulatory approvals, half of the commission will be paid to Marchant in the form of equity securities of the Company.

Industry (OcuSense)

Point-of-care Testing and Dry Eye Disease, or DED

The global market for point-of-care testing is currently $4.5 billion annually or 15% of the $30 billion global market for in-vitro diagnostic products. Approximately 75% of all laboratory tests today are performed at centralized clinical laboratories. However, there is an increasing frequency of diagnostic testing being performed at the point-of-care due to several factors, including a need for rapid testing in acute care situations, the benefits of patient monitoring and disease management, streamlining therapeutic decision making and the overall trend toward personalized medicine. Advances in biodetection technologies that can simplify and accelerate the rate of performing complex diagnostic tests at the point-of-care, and that are reimbursed, will drive utilization and overall point-of-care testing market growth.

OcuSense’s first product, currently under development, is the TearLab™ test for DED which is a test that can be performed at the point-of-care for the measurement of osmolarity, a quantitative and highly specific biomarker that has shown to correlate with DED. There are estimated to be more than 30 million people with DED in the U.S. alone, and this condition is estimated to account for up to one-third of all visits to U.S. doctors.

Each time a person blinks, his or her eyes are resurfaced with a thin layer of a complex fluid known as the tear film. The tear film works to protect eyes from the outside world. Bacteria, viruses, sand, freezing winds and salt water will not damage eyes when the tear film is intact. However, when compromised, a deficient tear film can be an exceedingly painful and disruptive experience. The tear film consists of three components: (i) an innermost mucin layer (produced by the surface cells); (ii) the aqueous layer (the water in tears, produced by the lacrimal gland); and (iii) an oily lipid layer which limits evaporation of the tears (produced by the meibomian glands, located at the margins of the eyelids). The apparatus of the ocular surface forms an integrated unit. When working correctly, the tear film presents a smooth optical surface essential for clear vision and proper immunity. However, when the tear film is disrupted, it leads to the condition known as DED.

DED is often seen as a result of aging, diabetes, prostate cancer therapy, HIV, autoimmune diseases such as Sjögren’s syndrome and rheumatoid arthritis, LASIK surgery, contact lens wear and menopause and as a side effect of hormone replacement therapy. Numerous commonly prescribed and over-the-counter medications also can cause, or contribute to, the manifestation of DED.

As an individual’s lacrimal glands deteriorate with age or disease, the quantity of tears is drastically reduced, resulting in an aqueous deficiency. Other forms of DED are linked to meibomian gland (lid) dysfunction, where a patient’s tears evaporate so quickly that he or she is unable to retain any moisture on the surface of his or her eye. The end effect in both cases, aqueous deficiency and evaporative dry eye, is a very debilitating condition that results in pain, decreased vision and, in severe cases, even blindness. Consequently, DED has a significant negative impact on one’s quality of life.

There are approximately 15 million Americans who suffer from contact lens-induced DED, and 10-15% of these patients revert to frame wear annually due to dryness and discomfort. There are approximately 1.2 million LASIK procedures performed in the U.S each year, and about 50% of patients experience DED post-operatively. Osmolarity testing could provide optometrists with a tool to identify patients at risk for dropping out of contact lens wear early in disease progression so that they may be treated, and osmolarity testing could be an invaluable pre-operative screen used to determine which LASIK patients should be treated prior to surgery in order to improve post-operative outcomes.

Diagnostic Alternatives for DED

Existing diagnostic assays are highly subjective, do not correlate well with symptoms, are invasive for patients and may require up to an hour of operator time to perform. All of these factors have constrained the diagnosis and treatment of the DED patient population. As physicians have not had access to objective, quantitative diagnostic assays that correlate well with symptoms and disease pathogenesis, it has been difficult for them to differentiate DED symptoms from other eye diseases that present with very similar symptoms, such as non-infectious ocular allergies or infectious bacterial or viral diseases. To treat DED effectively and to mitigate the emotional and physical effects of this disease, it will be critical to equip physicians with objective, quantitative measurements of disease pathogenesis so they can determine more accurately the most efficacious treatments for their patients.

DED presents itself as an increase in the salt concentration of the tear film. For approximately 50 years, studies have shown that tear film osmolarity is an ideal clinical marker for diagnosing DED, because it provides an objective, quantitative measurement of disease pathogenesis. Moreover, measuring osmolarity could serve as an effective disease management tool by providing physicians with an ability to personalize therapeutic intervention and to track patient outcomes quantitatively. However, measuring tear biomarkers, such as osmolarity, at the point-of-care requires a reduction in sample volume to the nanoliter scale in order to mitigate the risk of reflex tearing, which results in a dilution of the tear sample and a variability in the test results. Moreover, a point-of-care system in the U.S. market most likely would require a CLIA waiver classification in order to gain broad market adoption since most U.S. eye care practitioners do not possess CLIA certification for their offices. In order to be given CLIA waiver classification, the user interface of the test would have to be extremely simple in order to minimize the likelihood of operator error and the risk of harm to the patient. Conventional technologies for the measurement of osmolarity are not suitable for the point-of-care market as they are too expensive, too complex for CLIA waiver classification and unable to measure precisely tear film osmolarity in nanoliter sample volumes. OcuSense is striving to meet the needs of the point-of-care market with the TearLab™ test for DED.

Existing osmometry technologies have proven unable to measure consistently tear samples in the low nanoliter range, which has presented a critical barrier to their entry into the DED diagnostic markets. In addition, these instruments are not particularly suitable for use in a physician’s office, since they require continual calibration, cleaning and maintenance. Existing osmometers currently are marketed primarily to reference and hospital laboratories for the measurement of osmolarity in blood, urine and other serum samples.

OcuSense’s Product

OcuSense’s first product, the TearLab™ test for DED, which is currently under development, is an integrated testing system comprised of: (1) the TearLab™ disposable, which is a single-use microfluidic labcard; (2) the TearLab™ pen, which is a hand-held device that interfaces with the TearLab™ disposable; and (3) the TearLab™ reader, which is a small desktop unit that allows for the docking of the TearLab™ disposable and the TearLab™ pen and provides a quantitative reading for the operator. The anticipated innovation of the TearLab™ test for DED will be its ability to measure precisely and rapidly, and inexpensively, certain biomarkers in nanoliter volumes of tear samples. Current in-lab testing technologies require a minimum of one microliter volume tear film sample, or approximately 10 to 100 times more than the tear film volume typically available before reflex tearing occurs.

The operator of the TearLab™ test for DED, most likely a technician, will collect the tear sample from the patient’s eye in the TearLab™ disposable, using the TearLab™ pen, and then place the TearLab™ disposable into the TearLab™ reader. The TearLab™ reader then will display an osmolarity reading to the operator. Following the completion of the test, the TearLab™ disposable will be discarded and a new TearLab™ disposable will be readied for the next test. The entire process, from sample to answer, should require approximately two minutes or less to complete.

OcuSense is currently engaged in industrial, electrical and software design efforts for the three components of the TearLab™ test for DED and, to these ends, is working with two engineering partners, both based in Melbourne, Australia, one of which is a leader in biomedical instrument development and the other of which is a leader in customized microfluidics. In June 2007, OcuSense successfully produced and tested Alpha prototypes of the TearLab™ disposable, pen and reader in order to demonstrate the viability of the integrated system. OcuSense is working to achieve the successful production and testing of Beta prototypes of the TearLab™ disposable, pen and reader in order to validate system performance further and to prepare for commercial manufacturing. We anticipate that this milestone will be attained during the first half 2008.

In December 2007, OcuSense entered into a research agreement with a large ophthalmic company, pursuant to which that company is sponsoring OcuSense’s clinical studies of the TearLab™ test for DED. Pursuant to this research agreement, that company has paid for the future acquisition of a number of units of the beta version of the TearLab™ test for DED and has secured limited exclusive access to the beta version of the TearLab™ test for DED until OcuSense obtains a 510(k) clearance for it from the FDA.

Competition (OcuSense)

To date, OcuSense has identified one emerging technology that claims to be able to measure the osmolarity of nanoliter tear samples. This technology is being developed at the Aborn Eye Clinic in New York. Based on patent claims, it would appear that this technology uses surface plasmon resonance, an optical technology, to measure tear film osmolarity.

As there are no commercially available instruments to measure tear film osmolarity at the point-of-care, OcuSense views existing DED diagnostic tests, such as the Schirmer Test and ocular surface staining, as its primary source of competition.

Tear film break-up time, or TBUT, is another assay meant as an indication of tear film stability. However, it is subjective, requires a physician to instill a carefully controlled amount of fluorescein dye into the eye and requires a stopwatch to determine the endpoint. TBUT has been shown to be unreliable as a determinant of DED since shortened TBUT doesn’t always correlate well with other signs or symptoms.

Tests like impression cytology and corneal staining, although indicative of relatively late stage phenomena in DED, are subjective, qualitative and generally don’t correlate to disease pathogenesis. The Schirmer Test is an imprecise marker of tear function since its diagnostic results vary significantly.

Although, at the present time, there does not appear to be a direct competitor to the TearLab™ test for DED, many industry participants have much greater resources than OcuSense has, thus enabling them, among other things, to make greater research and development investments, and to make more significant investments in marketing, promotion and sales, than OcuSense is capable of right now or will be capable of during the foreseeable future.

Patents and Proprietary Rights (OcuSense)

OcuSense owns or has exclusive licenses to five U.S. patents relating to the TearLab™ test for DED and related technology and processes and has applied for a number of other patents in the United States and other jurisdictions.

OcuSense intends to rely on know-how, continuing technological innovation and in-licensing opportunities to develop further its proprietary position. OcuSense’s ability to obtain intellectual property protection for the TearLab™ test for DED and related technology and processes, and its ability to operate without infringing the intellectual property rights of others and to prevent others from infringing its intellectual property rights, will have a substantial impact on its ability to succeed in its business. Although OcuSense intends to seek to protect its proprietary position by, among other methods, continuing to file patent applications, the patent position of companies like OcuSense is generally uncertain and involves complex legal and factual questions. OcuSense’s ability to maintain and solidify a proprietary position for its technology will depend on its success in obtaining effective claims and enforcing those claims once granted. Neither OcuSense nor we know whether any part of its patent applications will result in the issuance of any patents. Its issued patents or those that may issue in the future, or those licensed to OcuSense, may be challenged, invalidated or circumvented, which could limit OcuSense’s ability to stop would-be competitors from marketing tests identical to the TearLab™ test for DED.

In addition to patent protection, OcuSense has registered the TearLab™ trademark in the U.S.

Government Regulation

Government authorities in the United States and other countries extensively regulate, among other things, the research, development, testing, manufacture, labeling, promotion, advertising, distribution and marketing of OcuSense’s product, which is a medical device. In the United States, the FDA regulates medical devices under the Federal Food, Drug, and Cosmetic Act and implementing regulations. Failure to comply with the applicable FDA requirements, both before and after approval, may subject us to administrative and judicial sanctions, such as a delay in approving or refusal by the FDA to approve pending applications, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, administrative fines and/or criminal prosecution.

Unless exempted by regulation, medical devices may not be commercially distributed in the United States unless they have been cleared or approved by the FDA. Medical devices are classified into one of the three classes, Class I, II or III, on the basis of the controls necessary to reasonably assure their safety and effectiveness. Class I devices are subject to general controls, such as labeling, pre-market notification and adherence to good manufacturing practices. Class II devices are subject to general and specific controls, such as performance standards, pre-market notification, patient registries and FDA guidelines. Generally, Class III devices are those which must receive approval of a PMA by the FDA to provide reasonable assurance of their safety and effectiveness. For example, life-sustaining, life-supporting and implantable devices, or new devices which have not been found substantially equivalent to legally marketed devices, generally require approval of a PMA by the FDA.

There are two review procedures by which medical devices can receive clearance or approval. Some products may qualify for clearance under a Section 510(k) procedure, in which the manufacturer provides a pre-market notification that it intends to begin marketing the product, and shows that the product is substantially equivalent to another legally marketed product, that it has the same intended use and is as safe and effective as a legally marketed device and does not raise different questions of safety and effectiveness than does a legally marketed device. In some cases, the submission must include data from human clinical studies. Marketing may commence when the FDA issues a clearance letter finding substantial equivalence.

By statute and regulation, the FDA is required to clear, deny or request additional information on a 510(k) pre-market notification within 90 days of its submission. However, as a practical matter, 510(k) clearance often takes significantly longer. The FDA may require additional information, including clinical data, to make a determination regarding substantial equivalence. In addition, after a device receives 510(k) clearance, any modification to the device that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, would require a new 510(k) clearance or an approval of a PMA. Although the FDA requires the manufacturer to make the initial determination regarding the effect of a modification to the device that is subject to 510(k) clearance, the FDA can review the manufacturer’s determination at any time and require the manufacturer to seek another 510(k) clearance or an approval of a PMA.

The TearLab™ test for DED is a Class I, non-exempt device and qualifies for the 510(k) procedure.

CLIA is intended to ensure the quality and reliability of clinical laboratories in the United States by mandating specific standards in the areas of personnel qualifications, administration, participation in proficiency testing, patient test management, quality control, quality assurance and inspections. The regulations promulgated under CLIA establish three levels of in vitro diagnostic tests: (1) waiver; (2) moderately complex; and (3) highly complex. The standards applicable to a clinical laboratory depend on the level of diagnostic tests it performs. A CLIA waiver is available to clinical laboratory test systems if they meet certain requirements established by the statute. Waived tests are simple laboratory examinations and procedures employing methodologies that are so simple and accurate as to render the likelihood of erroneous results negligible or to pose no reasonable risk of harm to patients if the examinations or procedures are performed incorrectly. These tests are waived from regulatory oversight of the user other than the requirement to follow the manufacturer’s labeling and directions for use.

We cannot be sure of when, or whether, OcuSense will be successful in obtaining a 510(k) clearance or a CLIA waiver for the TearLab™ test for DED.

If the medical device does not qualify for the 510(k) procedure, either because it is not substantially equivalent to a legally marketed device or because it is a Class III device required to have an approved PMA, then the FDA must approve a submitted PMA before marketing can begin. A PMA must demonstrate, among other matters, that the medical device is safe and effective. A PMA is typically a complex submission, usually including the results of preclinical and clinical studies, and preparing an application is a detailed and time-consuming process. The PMA must be accompanied by the payment of user fees which currently exceed $200,000 for most submissions. When modular submissions are used, the entire fee is due when the first module is submitted to the FDA. Once a PMA has been submitted, the FDA’s review may be lengthy and may include requests for additional data. The FDA usually inspects device manufacturers before approval of a PMA, and the FDA will not approve the PMA unless the manufacturer’s compliance with the quality systems regulation is satisfactory.

Regardless of whether a medical device requires FDA clearance or approval, a number of other FDA requirements apply to the device, its manufacturer and those who distribute it. Device manufacturers must be registered and their products listed with the FDA, and certain adverse events and product malfunctions must be reported to the FDA. The FDA also regulates the product labeling, promotion and, in some cases, advertising, of medical devices. In addition, manufacturers and their suppliers must comply with the FDA’s quality system regulation which establishes extensive requirements for quality and manufacturing procedures. Thus, suppliers, manufacturers and distributors must continue to spend time, money and effort to maintain compliance, and failure to comply can lead to enforcement action. The FDA periodically inspects facilities to ascertain compliance with these and other requirements.

Employees

On December 31, 2007, we had 24 full-time employees. Of our full-time workforce at that time, 12 employees were engaged in clinical trial activities and 12 were engaged in business development, finance and administration. With the suspension of the Company's RHEO System clinical development program, and the consequent winding-down of the RHEO-AMD study, and the Company's disposition of SOLX, the Company has reduced its workforce considerably. At the present time, we have 7 full-time employees. However, we continue to retain outside consultants, some of whom are our former employees. None of our employees are covered by collective bargaining arrangements, and our management considers its relationship with our employees to be good.

We continue to rely on the resources of one of our major stockholders, TLC Vision, to provide us with infrastructure support.

Risk Factors

Risks Relating to Our Business

Our financial condition and history of losses have caused our auditors to express doubt as to whether we will be able to continue as a going concern.

We have prepared our consolidated financial statements on the basis that we will continue as a going concern. However, the Company has sustained substantial losses for each of the years ended December 31, 2007, 2006 and 2005. The Company's working capital deficiency at December 31, 2007 is $996,862, which represents a $14,535,888 reduction in its working capital of $13,539,026 at December 31, 2006. As a result of our history of losses and current financial condition, there is substantial doubt about the Company's ability to continue as a going concern.

The Company realized gross proceeds of $10,016,000 (less transaction costs of $871,215) on February 6, 2007 from the private placement of shares of its common stock and warrants. Management believed that these proceeds, together with the Company's then existing cash, would be only sufficient to cover its operating activity and other demands until early 2008. On February 19, 2008, the Company secured a bridge loan in an aggregate principal amount of $3,000,000 from a number of private parties and, taking into account transactions costs of approximately $200,000, realized net proceeds of approximately $2,800,000. The loan bears interest at a rate of 12% per annum and has a 180-day term, which may be extended to 270 days under certain circumstances. The repayment of the loan is secured by a pledge by OccuLogix of its shares of the capital stock of OcuSense. Management believes that these net proceeds, together with our existing cash and cash-equivalents, will be sufficient to cover its operating activities and other demands only until approximately the end of April 2008 (assuming that the outstanding obligation of OccuLogix to pay $2,000,000 to OcuSense becomes due and payable prior to the end of April 2008).

Our consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary if the Company were not able to continue as a going concern.

We have incurred losses since inception and anticipate that we will incur continued losses for the foreseeable future.

We have incurred losses in each year since our inception in 1996. Our net loss for the fiscal years ended December 31, 2007, 2006, 2005, 2004 and 2003 was $69.8 million, $82.2 million, $162.8 million, $21.8 million and $2.5 million, respectively. The losses in 2007, 2006 and 2005 include a charge for impairment of goodwill of $14.4 million, $65.9 million and $147.5 million, respectively. As of December 31, 2007, we had an accumulated deficit of $358.3 million. These losses, among other things, have had and will continue to have an adverse effect on our stockholders’ equity and working capital. We remain indebted to OcuSense in an aggregate amount of $2 million for the outstanding portion of the purchase price of the capital stock of OcuSense that we acquired on November 30, 2006. Currently, we anticipate that that amount will become due and payable during the first half of 2008. Furthermore, we are legally committed to make an additional equity investment of $3 million upon receipt, if any, from the FDA of a 510(k) clearance for the TearLab™ test for DED and another additional equity investment of $3 million upon receipt, if any, from the FDA of a CLIA waiver for the TearLab™ test for DED. Because of the numerous risks and uncertainties facing us, we are unable to predict the extent of any future losses or when we will become profitable, if ever, or even if we will be able to continue as a going concern.

We may not be able to raise the capital necessary to fund our operations.

Since inception, we have funded our operations through early private placements of our equity and debt securities, early stage revenues, a successful initial public offering, or IPO, a private placement of shares of our common stock and warrants on February 6, 2007 and, most recently, on February 19, 2008, a bridge loan. Prior to the IPO, our cash resources were limited. We will need additional capital in the future, and our prospects for obtaining it are uncertain. On October 9, 2007, we announced that the Board had authorized management and our advisors to explore the full range of strategic alternatives available to enhance shareholder value, including, but not limited to, the raising of capital through the sale of securities, one or more strategic alliances and the combination, sale or merger of all or part of the Company. For some time prior to the October 9, 2007 announcement, the Company had been seeking to raise additional capital, with the objective of securing funding sufficient to sustain its operations as it had been clear that, unless we were able to raise additional capital, the Company would not have had sufficient cash to support its operations beyond early 2008. Although the Company secured a bridge loan in an aggregate principal amount of $3,000,000 from a number of private parties on February 19, 2008, management believes that these net proceeds, together with our existing cash and cash-equivalents, will be sufficient to cover its operating activities and other demands only until approximately the end of April 2008 (assuming that the outstanding obligation of OccuLogix to pay $2,000,000 to OcuSense becomes due and payable prior to the end of April 2008). Additional capital may not be available on terms favorable to us, or at all. In addition, future financings could result in significant dilution of existing stockholders. However, unless we succeed in raising additional capital, we will be unable to continue our operations. See “Risk Factors—Risks Relating to Our Business—Our financial condition and history of losses have caused our auditors to express doubt as to whether we will be able to continue as a going concern.”

We no longer operate any business.

With the suspension of the Company's RHEO™ System clinical development program, and the consequent winding-down of the RHEO-AMD study, and the Company's disposition of SOLX, the Company no longer has any operating business. Its major asset is its 50.1% ownership stake, on a fully diluted basis, 57.62% on an issued and outstanding basis, in OcuSense. Accordingly, unless we acquire other businesses (which, in light of the Company's financial condition, is unlikely to occur), our ability to generate any revenues will be dependent almost entirely upon the success of OcuSense.

The Company's major asset is encumbered.

The repayment of the bridge loan, in the aggregate principal amount of $3,000,000, which the Company secured on February 19, 2008 from a number of private parties, is secured by a pledge by OccuLogix of its shares of the capital stock of OcuSense. If the Company fails to repay this loan and accrued interest by the loan’s maturity date, which will occur on the 180th day following February 19, 2008 or, under certain circumstances, the 270th day following February 19, 2008, the lenders may realize upon their collateral and seize OccuLogix’s shares of the capital of OcuSense, thus causing the Company to lose its major asset. Accordingly, the Company may lose its major asset unless it succeeds in raising additional capital in an amount sufficient to repay the loan and accrued interest by the loan’s maturity date—which the Company is permitted to do through a sale of the collateral, provided that the sale generates proceeds in an amount sufficient to repay the loan and accrued interest if full.

The $3,000,000 aggregate principal amount bridge loan represents a significant dilution risk for existing stockholders.

Under the terms of the loan agreement pursuant to which the Company secured a bridge loan, in the aggregate principal amount of $3,000,000, on February 19, 2008 from a number of private parties, the Company has two pre-payment options available to it, should it decide to not wait until the maturity date to repay the loan. Under the first pre-payment option, the Company may repay the loan in full by paying the lenders, in cash, the amount of outstanding principal and accrued interest and issuing to the lenders five-year warrants in an aggregate amount equal to approximately 19.9% of the issued and outstanding shares of the Company's common stock (but not to exceed 20% of the issued and outstanding shares of the Company's common stock). The warrants would be exercisable into shares of the Company's common stock at an exercise price of $0.10 per share and would not become exercisable until the 180th day following their issuance. Under the second pre-payment option, provided that the Company has closed a private placement of shares of its common stock for aggregate gross proceeds of at least $4,000,000, the Company may repay the loan in full by issuing to the lenders shares of its common stock, in an aggregate amount equal to the amount of outstanding principal and accrued interest, at a 15% discount to the price paid by the private placement investors. An exercise by the Company of either pre-payment option will result in significant dilution of the holdings of existing stockholders. Any exercise by the Company of the second pre-payment option would be subject to stockholder and regulatory approval.

OcuSense will face challenges in bringing the TearLab™ test for DED to market and may not succeed in executing its business plan.

At the present time, OcuSense is relying almost entirely on OccuLogix to fund its business. Following the payment by OccuLogix of $2,000,000 upon OcuSense’s successful production and testing of the beta version of the TearLab™ test for DED, there can be no assurance that OccuLogix will be a reliable source of future funding for OcuSense, notwithstanding its agreement to purchase $3,000,000 of shares of OcuSense’s Series B Preferred Stock upon OcuSense’s receipt from the FDA, if any, of 510(k) clearance for the TearLab™ test for DED and to purchase another $3,000,000 of shares of OcuSense’s Series B Preferred Stock upon OcuSense’s receipt from the FDA, if any, of a CLIA waiver for the TearLab™ test for DED.

There are numerous risks and uncertainties inherent in the development of new medical technologies. In addition to OcuSense’s eventual requirement for additional capital, OcuSense’s ability to bring the TearLab™ test for DED to market and to execute its business plan successfully is subject to the following risks, among others:

OcuSense’s clinical trials may not succeed. Clinical testing is expensive and can take longer than originally anticipated. The outcomes of clinical trials are uncertain, and failure can occur at any stage of the testing. OcuSense could encounter unexpected problems, which could result in a delay in the submission of its applications for the sought-after FDA approvals or prevent their submission altogether.

OcuSense may not receive either the 510(k) clearance or the CLIA waiver for the TearLab™ test for DED that it will be seeking from the FDA, in which case OcuSense’s ability to market the TearLab™ test for DED in the United States will be hindered severely, if not eliminated altogether.

OcuSense and its suppliers will be subject to numerous FDA requirements covering the design, testing, manufacturing, quality control, labeling, advertising, promotion and export of the TearLab™ test for DED and other matters. If OcuSense or its suppliers fail to comply with these regulatory requirements, the TearLab™ System could be subject to restrictions or withdrawals from the market and OcuSense could become subject to penalties.

Even if it succeeds in obtaining the sought-after FDA approvals, OcuSense may be unable to commercialize the TearLab™ test for DED successfully in the United States. Successful commercialization will depend on a number of factors, including, among other things, achieving widespread acceptance of the TearLab™ test for DED among physicians, establishing adequate sales and marketing capabilities, addressing competition effectively, the ability to obtain and enforce patents to protect proprietary rights from use by would-be competitors, key personnel retention and ensuring sufficient manufacturing capacity and inventory to support commercialization plans.

OcuSense’s patents may not be valid, and OcuSense may not be able to obtain and enforce patents to protect its proprietary rights from use by would-be competitors. Patents of other companies could require OcuSense to stop using or pay to use required technology.

OcuSense’s owned and licensed patents may not be valid, and it may not be able to obtain and enforce patents and to maintain trade secret protection for its technology. The extent to which OcuSense is unable to do so could materially harm its business.

OcuSense has applied for, and intends to continue to apply for, patents relating to the TearLab™ test for DED and related technology and processes. Such applications may not result in the issuance of any patents, and any patents now held or that may be issued may not provide adequate protection from competition. Furthermore, it is possible that patents issued or licensed to OcuSense may be challenged successfully. In that event, if OcuSense has a preferred competitive position because of any such patents, any preferred position held by OcuSense would be lost. If OcuSense is unable to secure or to continue to maintain a preferred position, the TearLab™ test for DED could become subject to competition from the sale of generic products.

Patents issued or licensed to OcuSense may be infringed by the products or processes of others. The cost of enforcing patent rights against infringers, if such enforcement is required, could be significant and the time demands could interfere with OcuSense’s normal operations. There has been substantial litigation and other proceedings regarding patent and other intellectual property rights in the pharmaceutical, biotechnology and medical technology industries. OcuSense could become a party to patent litigation and other proceedings. The cost to it of any patent litigation, even if resolved in its favor, could be substantial. Some of OcuSense’s would-be competitors may be able to sustain the costs of such litigation more effectively than it can because of their substantially greater financial resources. Litigation may also absorb significant management time.

Unpatented trade secrets, improvements, confidential know-how and continuing technological innovation are important to OcuSense’s future scientific and commercial success. Although it attempts to, and will continue to attempt to, protect its proprietary information through reliance on trade secret laws and the use of confidentiality agreements with corporate partners, collaborators, employees and consultants and other appropriate means, these measures may not effectively prevent disclosure of OcuSense’s proprietary information, and, in any event, others may develop independently, or obtain access to, the same or similar information.

Certain of OcuSense’s patent rights are licensed to it by third parties. If OcuSense fails to comply with the terms of these license agreements, its rights to those patents may be terminated, and OcuSense will be unable to conduct its business.

It is possible that a court may find OcuSense to be infringing upon validly issued patents of third parties. In that event, in addition to the cost of defending the underlying suit for infringement, OcuSense may have to pay license fees and/or damages and may be enjoined from conducting certain activities. Obtaining licenses under third-party patents can be costly, and such licenses may not be available at all.

Our common stock may be delisted from The Nasdaq Global Market.

On September 18, 2007, OccuLogix received a letter from The Nasdaq Stock Market, or Nasdaq, indicating that, for the previous 30 consecutive business days, the bid price of the Company's common stock closed below the minimum $1.00 per share requirement for continued inclusion under Marketplace Rule 4450(e)(5), or the Minimum Bid Price Rule. Therefore, in accordance with Marketplace Rule 4450(e)(2), the Company was provided 180 calendar days, or until March 17, 2008, to regain compliance. The Nasdaq letter stated that, if, at any time before March 17, 2008, the bid price of the Company's common stock closes at $1.00 per share or more for a minimum of 10 consecutive business days, Nasdaq staff will provide written notification that it has achieved compliance with the Minimum Bid Price Rule. The Nasdaq letter also stated that, if the Company does not regain compliance with the Minimum Bid Price Rule by March 17, 2008, Nasdaq staff will provide written notification that the Company's securities will be delisted, at which time the Company may appeal the Nasdaq staff’s determination to delist its securities to a Nasdaq Listing Qualifications Panel.

On February 1, 2008, OccuLogix received a letter from Nasdaq indicating that, for the previous 30 consecutive trading days, the Company's common stock did not maintain a minimum market value of publicly held shares of $5,000,000 as required for continued inclusion by Marketplace Rule 4450(a)(2), or the MVPHS Rule. Therefore, in accordance with Marketplace Rule 4450(e)(1), the Company was provided 90 calendar days, or until May 1, 2008, to regain compliance. The Nasdaq letter stated that, if at any time before May 1, 2008, the minimum market value of publicly held shares of the Company's common stock is $5,000,000 or greater for a minimum of ten consecutive trading days, Nasdaq staff will provide written notification that the Company complies with the MVPHS Rule. The Nasdaq letter also stated that, if the Company does not regain compliance with the MVPHS Rule by May 1, 2008, Nasdaq staff will provide written notification that the Company's securities will be delisted, at which time the Company may appeal the Nasdaq staff’s determination to delist its securities to a Nasdaq Listing Qualifications Panel.

The Company will not have become compliant with the Minimum Bid Price Rule by March 17, 2008. Although we intend to appeal any determination by Nasdaq staff to delist our common stock to a Nasdaq Listing Qualifications Panel, we may not be successful in our appeal, in which case our common stock may be transferred to The Nasdaq Capital Market or be delisted altogether. Should either occur, existing stockholders will suffer decreased liquidity.

OcuSense and we may face future product liability claims.

The testing, manufacturing, marketing and sale of therapeutic and diagnostic products entail significant inherent risks of allegations of product liability. Our past use of the RHEO™ System and the components of the SOLX Glaucoma System in clinical trials and the commercial sale of those products may have exposed us to potential liability claims. OcuSense’s future use of the TearLab™ test for DED and its commercial sale could expose it to liability claims also. All of such claims might be made directly by patients, health care providers or others selling the products. We carry clinical trials and product liability insurance to cover certain claims that could arise, or that could have arisen, during our clinical trials or during the commercial use of our products. We currently maintain clinical trials and product liability insurance with coverage limits of $5,000,000 in the aggregate annually. Such coverage, and any coverage obtained in the future, may be inadequate to protect OcuSense or us in the event of successful product liability claims, and neither OcuSense nor we may be able to increase the amount of such insurance coverage or even renew it. A successful product liability claim could materially harm our business. In addition, substantial, complex or extended litigation could result in the incurrence of large expenditures and the diversion of significant resources.

For as long as TLC Vision owns a substantial portion of our common stock, our other stockholders may be effectively unable to affect the outcome of stockholder voting.

TLC Vision beneficially owns approximately 32.8% of our outstanding common stock, or 28.9% on a fully diluted basis. Accordingly, TLC Vision, in conjunction with other stockholders, could possess an effective controlling vote on matters submitted to a vote of the holders of our common stock.

While it owns a substantial portion of our common stock, TLC Vision could effectively control decisions with respect to:

•

our business direction and policies, including the election and removal of our directors;

•

mergers or other business combinations involving us;

•

the acquisition or disposition of assets by us;

•

our financing; and

•

amendments to our certificate of incorporation and bylaws.

Furthermore, TLC Vision may be able to cause or prevent a change of control of the Company, and this concentration of ownership may have the effect of discouraging others from pursuing transactions involving a potential change of control of the Company, in either case regardless of whether a premium is offered over then-current market prices.

Conflicts of interest may arise between us and TLC Vision, which, until December 2007, had two directors on our board and currently has one director on our board. Our Chief Executive Officer and Chairman served as Chairman of TLC Vision until June 2006.

TLC Vision beneficially owns approximately 32.8% of our outstanding common stock, or 28.9% on a fully diluted basis. Our director, Richard Lindstrom, is also a director of TLC Vision. Until June 2007 and December 2007, respectively, our directors, Elias Vamvakas and Thomas Davidson, also served as directors of TLC Vision. Mr. Vamvakas beneficially owns 1,041,795 common shares of TLC Vision, representing approximately 2.08% of TLC Vision’s outstanding shares. Mr. Davidson beneficially owns 67,127 common shares of TLC Vision, representing approximately 0.14% of TLC Vision’s outstanding shares, and Dr. Lindstrom beneficially owns 29,500 common shares of TLC Vision, representing approximately 0.06% of TLC Vision’s outstanding shares. Because Dr. Lindstrom is a director of TLC Vision, a conflict of interest could arise. Conflicts may arise between TLC Vision and us as a result of our ongoing agreements. We may not be able to resolve all potential conflicts with TLC Vision, and even if we do, the resolution may be less favorable to us than if we were dealing with an unaffiliated third party.

We have entered into a number of related party transactions with suppliers, creditors, stockholders, officers and other parties, each of which may have interests which conflict with those of our public stockholders.

We have entered into several related party transactions with our suppliers, creditors, stockholders, officers and other parties, each of which may have interests which conflict with those of our public stockholders.

ITEM 2.

PROPERTIES.

In December 2004, we moved from our previous headquarters which we subleased from TLC Vision to our current headquarters, which are also in Mississauga. Until January 31, 2006, we subleased our current headquarters from Echo Online Internet, Inc. and, between February 1, 2006 to July 31, 2007, leased them from Penyork Properties III Inc. Since August 1, 2007, we have been leasing them from 2600 Skymark Investments Inc., the successor in interest to Penyork Properties III Inc. The facility presently consists of approximately 6,600 square feet of office space utilized for management personnel. Our current arrangement expires on July 31, 2010. Our current monthly lease obligation for rent for this facility is approximately C$13,283. The future minimum obligation under this lease is C$159,390 for 2008. TLC Vision has advised us that it does not have any ownership interest in our current headquarters.

We also leased space in a facility in Palm Harbor, Florida consisting of 5,020 square feet of space used for warehousing the RHEO™ System components and providing office space for certain members of our clinical trial personnel and John Cornish, who was formerly our Vice President, Operations, and records. The facility consisted of office and working space and an approximately 1,700 square foot warehouse in the back. Our lease on this property expired on December 31, 2007 and has not been renewed. Our monthly lease obligation for rent for this facility was approximately $2,168. The future minimum obligation under this lease is therefore nil for 2008. The landlord under this lease was Cornish Properties, which is owned by Mr. Cornish. Mr. Cornish was also one of our directors from April 1997 to September 2004.

In addition, OcuSense leases office space in facilities owned by parties unrelated to us. The total future minimum obligation under these leases is $40,851 for 2008.

We believe that if our existing facilities are not adequate to meet our business requirements for the near-term, additional space will be available on commercially reasonable terms.

ITEM 3.

LEGAL PROCEEDINGS.

We are not aware of any material litigation involving us that is outstanding, threatened or pending.

ITEM 4.

SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

No matter was submitted during the fourth quarter of the Company's 2007 fiscal year to a vote of security holders, through the solicitation of proxies or otherwise.

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our restated consolidated financial statements and related notes, included in Item 8 of this Amended Report. Unless otherwise specified, all dollar amounts are U.S. dollars.

Overview

We are an ophthalmic therapeutic company founded to commercialize innovative treatments for age-related eye diseases. Until recently, the Company operated two business divisions, being Retina and Glaucoma. Until recently, the Company's Retina division was in the business of developing and commercializing a treatment for dry age-related macular degeneration, or Dry AMD. The Company's product for Dry AMD, the RHEO™ System contains a pump that circulates blood through two filters and is used to perform the Rheopheresis™ procedure, which is referred to under the Company's trade name RHEO™ Therapy. The Rheopheresis™ procedure is a blood filtration procedure that selectively removes molecules from plasma, which is designed to treat Dry AMD, the most common form of the disease.

The Company conducted a pivotal clinical trial, called MIRA-1, or Multicenter Investigation of Rheopheresis for AMD, which, if successful, was expected to support our application to the U.S. Food and Drug Administration, or FDA, to obtain approval to market the RHEO™ System in the United States. On February 3, 2006, we announced that, based on a preliminary analysis of the data from MIRA-1, MIRA-1 did not meet its primary efficacy endpoint as it did not demonstrate a statistically significant difference in the mean change of Best Spectacle-Corrected Visual Acuity applying the Early Treatment Diabetic Retinopathy Scale, or ETDRS BCVA, between the treated and placebo groups in MIRA-1 at 12 months post-baseline. As expected, the treated group demonstrated a positive result. An anomalous response of the control group is the principal reason why the primary efficacy endpoint was not met. There were subgroups that did demonstrate statistical significance in their mean change of ETDRS BCVA.

Subsequent to the February 3, 2006 announcement, we completed an in-depth analysis of the MIRA-1 study data identifying subjects that were included in the intent-to-treat, or ITT, population but who deviated from the MIRA-1 protocol as well as those patients who had documented losses or gains in vision for reasons not related to retinal disease such as cataracts. Those subjects in the ITT population who met the protocol requirements, and who did not exhibit ophthalmic changes unrelated to retinal disease, comprised the modified per-protocol population.

In light of the MIRA-1 study results, we also re-evaluated our Pre-market Approval Application, or PMA, submission strategy and then met with representatives of the FDA on June 8, 2006 in order to discuss the impact the MIRA-1 results would have on our PMA to market the RHEO™ System in the United States. In light of MIRA-1’s failure to meet its primary efficacy endpoint, the FDA advised us that it will require an additional study of the RHEO™ System to be performed.

However, on November 1, 2007, the Company announced the indefinite suspension of its RHEO™ System clinical development program. This decision was made following a comprehensive review of the respective costs and development timelines associated with the products in the Company's portfolio and in light of the Company's financial position. Between January 29, 2007 and November 1, 2007, the Company had prepared the RHEO-AMD protocol and had been putting into place all of the resources required for the conduct for the RHEO-AMD study, including the securing of clinical trial site commitments. The Company are in the process of winding down the RHEO-AMD study as there is no reasonable prospect that the RHEO™ System clinical development program will be relaunched in the foreseeable future. Subsequent to our fiscal 2007 year-end, as of February 25, 2008, we have terminated our relationship with Asahi Kasei Kuraray Medical Co., Ltd. (formerly Asahi Kasei Medical Co., Ltd.), or Asahi Medical. Asahi Medical manufactures, and supplied us with, the Rheofilter filter and the Plasmaflo filter, both of which are key components of the RHEO™ System. We also are engaged in discussions with Diamed Medizintechnik GmbH, or Diamed, and MeSys GmbH, or MeSys, regarding the termination of our relationship with each of them. Diamed is the designer, and MeSys is the manufacturer, of the OctoNova pump, another key component of the RHEO™ System.

As a result of the announcement on February 3, 2006, the per share price of our common stock as traded on the NASDAQ Global Market, or NASDAQ, decreased from $12.75 on February 2, 2006 to close at $4.10 on February 3, 2006. The 10-day average price of the stock immediately following the announcement was $3.65 and reflected a decrease in our market capitalization from $536.6 million on February 2, 2006 to $153.6 million based on the 10-day average share price subsequent to the announcement. On June 12, 2006, we announced that the FDA will require us to perform an additional study of the RHEO™ System. In addition, on June 30, 2006, we announced that we had terminated negotiations with Sowood Capital Management LP (“Sowood”) in connection with a proposed private purchase of approximately $30,000,000 of zero-coupon convertible notes of the Company's. The per share price of our common stock decreased subsequent to the June 12, 2006 announcement and again after the June 30, 2006 announcement. Based on the result of the analysis of the data from MIRA-1 and the events that occurred during the second quarter of fiscal 2006, we concluded that there were sufficient indicators of impairment leading to an analysis of our intangible assets and goodwill and resulting in our reporting an impairment charge to goodwill of $65,945,686 and $147,451,758 in the second quarter of 2006 and in the fourth quarter of 2005, respectively.

We considered the Company's announcement of the indefinite suspension of our RHEO™ System clinical development program for Dry AMD to be a significant event which may affect the carrying value of our intangible assets. This led to an analysis of our intangible assets and resulted in our reporting an impairment charge to intangible assets of $20,923,028 during the third quarter of 2007. We also believe that we may not be able to sell or utilize the components of the RHEO™ System prior to their expiration dates or before the technologies become outdated, as the case may be. Accordingly, we set up a provision for obsolescence of $2,782,494 for treatment sets and OctoNova pumps that are unlikely to be utilized prior to their expiration dates, in the case of treatment sets, or before the technologies become outdated. In addition, we have recorded a reduction to the carrying values of (i) certain of our medical equipment used in the clinical trials of the RHEO™ System of $431,683 and (ii) certain of our patents and trademarks related to the RHEO™ System of $190,873. No other adjustments were made as a result of the November 1, 2007 announcement that impacts the financial results as of December 31, 2007.

On September 29, 2004, we signed a product purchase agreement with Veris Health Sciences Inc. (formerly RHEO Therapeutics, Inc.), or Veris, for the purchase and sale of 8,004 treatment sets over the period from October 2004 to December 2005, a transaction valued at $6,003,000, after introductory rebates. However, due to delays in opening its planned number of clinics throughout Canada, Veris no longer required the contracted-for number of treatment sets in the period. We agreed to the original pricing for the reduced number of treatment sets required in the period. In December 2005, by letter agreement, we agreed to the volume and other terms for the purchase and sale of treatment sets and pumps for the period ending February 28, 2006. As at December 31, 2005, the Company had received a total of $1,779,566 from Veris. Included in amounts receivable, net as at December 31, 2005 was $1,049,297 due from Veris for the purchase of additional pumps and treatment sets.

We believed that the announcement on February 3, 2006 made it unlikely that we would be able to collect on amounts outstanding from Veris as at December 31, 2005. This resulted in a provision for bad debts of $1,049,297 during the year ended December 31, 2005, of which $518,852 related to revenue recognized prior to December 31, 2005 and $530,445 related to goods shipped to Veris in December 2005, for which revenue was not recognized. We also recognized an inventory loss of $252,071 during the year ended December 31, 2005, representing the cost of goods shipped to Veris in December 2005 which we do not anticipate will be returned by Veris. During the year ended December 31, 2005, we also fully expensed the C$195,000 advance paid to Veris in connection with clinical trial services to be provided by Veris for MIRA-PS, one of our clinical trials which we have suspended. In addition, we evaluated our ending inventories as at December 31, 2005 on the basis that Veris may not be able to increase its commercial activities in Canada in line with our initial expectations. Accordingly, we set up a provision for obsolescence of $1,990,830 during the year ended December 31, 2005 for treatment sets that will unlikely be utilized prior to their expiration dates.

During the year ended December 31, 2006, we sold a number of treatment sets, with a negotiated discount, to Veris at a price lower than our cost. Accordingly, the price which we charged to Veris, net of a negotiated discount, represents the current net realizable value; therefore, we wrote down the value of our treatment sets by $1,625,000 to reflect their current net realizable value as at December 31, 2006. We also set up an additional provision for obsolescence of $1,679,124 during the year ended December 31, 2006 for treatment sets that will unlikely be utilized prior to their expiration dates. In addition, based on our November 1, 2007 announcement of the indefinite suspension of our RHEO™ System clinical development program, we wrote down the value of our pumps and clinical inventory by $2,790,209 to reflect their current net realizable value as at December 31, 2007.

As at December 31, 2007 and 2006, we had combined inventory reserves of $7,295,545 and $5,101,394, respectively.

In June 2006, Veris returned four pumps which had been sold to it in December 2005. In fiscal 2005, we did not recognize revenue on sales made to Veris in December 2005 and had recorded an inventory loss associated with all sales made to Veris in December 2005. Accordingly, as at December 31, 2006, amounts receivable and the allowance for doubtful account recorded against the amount due from Veris have been reduced by the invoiced amount for the four pumps of $143,520. In addition, the cost of the four pumps returned by Veris, valued at $85,058, was used to reduce the cost of sales in the period.

On November 6, 2006, we amended the product purchase agreement with Veris and agreed to forgive the outstanding amount receivable of $904,101 from Veris which had been owing for the purchase of treatment sets and pumps and for related services delivered or provided to Veris from September 14, 2005 to December 31, 2006. In consideration of the forgiveness of this debt, Veris agreed that we do not owe any amounts whatsoever in connection with (i) our use of the leasehold premises located at 5280 Solar Drive in Mississauga, Ontario or (ii) legal fees and expenses incurred by Veris prior to February 14, 2006 with respect to those trademarks of Veris that were assigned to us on February 14, 2006.

In November 2006, we sold a total of 348 treatment sets to Veris for $73,776, including applicable taxes, payment for which was not received by us within the agreed credit period. The sale of these treatment sets was not recognized as revenue during the year ended December 31, 2006 as we believe that Veris would not be able to meet its financial obligations to us. In January 2007, we met with the management of Veris and agreed to forgive the outstanding amount receivable of $73,776 which was owing for the purchase of the 348 treatment sets delivered to Veris in November 2006. We also recognized an inventory loss of $60,987 during the year ended December 31, 2006, representing the cost of the 348 treatment sets shipped to Veris in November 2006.

We entered into a distributorship agreement (the “Distribution Agreement”), effective October 20, 2006, with Asahi Medical. The Distribution Agreement replaced the 2001 distributorship agreement between Asahi Medical and us, as supplemented and amended by the 2003, 2004 and 2005 Memoranda. Pursuant to the Distribution Agreement, we had distributorship rights to Asahi Medical's Plasmaflo filter and Asahi Medical's second generation polysulfone Rheofilter filter on an exclusive basis in the United States, Mexico and certain Caribbean countries, on an exclusive basis in Canada, on an exclusive basis in Colombia, Venezuela, New Zealand, Australia and on a non-exclusive basis in Italy.

On January 28, 2008, the Company disclosed that it was engaged in discussions with Asahi Medical to terminate the Distribution Agreement. Subsequent to our 2007 fiscal year end, the Company and Asahi Medical have entered into a termination agreement to terminate substantially all of their obligations under the Distribution Agreement on and as of February 25, 2008 (the “Termination Agreement”). Pursuant to the Termination Agreement, the Company and Asahi Medical have agreed to a mutual release of claims relating to the Distribution Agreement, other than any claims relating to certain provisions of the Distribution Agreement which survived its termination.

In anticipation of the delay in the commercialization of the RHEO™ System in the United States as a result of the MIRA-1 study’s failure to meet its primary efficacy endpoint and the FDA’s requirement of us to conduct an additional study of the RHEO™ System, the Company accelerated our diversification plans and, on September 1, 2006, acquired Solx, Inc., or SOLX, for a total purchase price of $29,068,443 which included acquisition-related transaction costs of $851,279. SOLX is a Boston University Photonics Center-incubated company that has developed a system for the treatment of glaucoma, called the SOLX Glaucoma System. The SOLX Glaucoma Treatment System is a next-generation treatment platform designed to reduce intra-ocular pressure, or IOP, without a bleb, thus avoiding its related complications. The SOLX Glaucoma System consists of the SOLX 790 Laser, a titanium sapphire laser used in laser trabeculoplasty procedures, and the SOLX Gold Shunt, a 24-karat gold, ultra-thin drainage device designed to bridge the anterior chamber and the suprachoroidal space in the eye, using the pressure differential that exists naturally in the eye in order to reduce IOP.

On December 20, 2007, we announced the sale of SOLX to Solx Acquisition, Inc., or Solx Acquisition, a company wholly owned by Doug P. Adams, the founder of SOLX and who, until the closing of the sale, had been serving as an executive officer of the Company in the capacity of President & Founder, Glaucoma Division. The results of operations of SOLX have been included in discontinued operations in the Company's consolidated statements of operations.

The consideration for the purchase and sale of all of the issued and outstanding shares of the capital stock of SOLX consisted of: (i) on December 19, 2007, the closing date of the sale, the assumption by Solx Acquisition of all of the liabilities of the Company, as they related to SOLX’s business, incurred on or after December 1, 2007, and OccuLogix’s obligation to make a $5,000,000 payment to the former stockholders of SOLX due on September 1, 2008 in satisfaction of the outstanding balance of the purchase price of SOLX; (ii) on or prior to February 15, 2008, the payment by Solx Acquisition of all of the expenses that the Company had paid to the closing date, as they related to SOLX’s business during the period commencing on December 1, 2007; (iii) during the period commencing on the closing date and ending on the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 3% of the worldwide net sales of the SOLX 790 Laser and the SOLX Gold Shunt, including next-generation or future models or versions of these products; and (iv) following the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 5% of the worldwide net sales of these products. In order to secure the obligation of Solx Acquisition to make these royalty payments, SOLX granted to OccuLogix a subordinated security interest in certain of its intellectual property. In connection with the sale of SOLX, those employees of the Company, whose roles and responsibilities related mainly to SOLX’s business, ceased to be our employees and became employees of Solx Acquisition or SOLX.

The sale transaction established fair values for the Company recorded goodwill and the Company shunt and laser technology and regulatory and other intangible assets that had been acquired by the Company upon its acquisition of SOLX on September 1, 2006. Accordingly, management was required to re-assess whether the carrying value of the Company shunt and laser technology and regulatory and other intangible assets was recoverable as of December 1, 2007. Based on management’s estimates of undiscounted cash flows associated with these intangible assets, we concluded that the carrying value of these intangible assets was not recoverable as of December 1, 2007. Accordingly, we recorded an impairment charge of $22,286,383 during the year ended December 31, 2007 to record the shunt and laser technology and regulatory and other intangible assets at their fair value as of December 31, 2007

Both the SOLX 790 Laser and the SOLX Gold Shunt are currently the subject of randomized, multi-center clinical trials, the purposes of which are to demonstrate equivalency to the argon laser, in the case of the SOLX 790 Laser, and to the Ahmed Glaucoma Valve manufactured by the New World Medical, Inc., in the case of the SOLX Gold Shunt. The results of these clinical trials will be used in support of applications to the FDA for a 510(k) clearance for each of the SOLX 790 Laser and the SOLX Gold Shunt, the receipt of which, if any, will enable the marketing and sale of these products in the United States.

As part of our diversification plan, on November 30, 2006, we acquired 50.1% of the capital stock of OcuSense, Inc., or OcuSense, measured on a fully diluted basis, 57.62% on an issued and outstanding basis, for a total purchase price of $4,171,098 which includes acquisition-related transaction costs of $171,098. We agreed to make additional payments totaling $4,000,000 upon the attainment of two pre-defined milestones by OcuSense prior to May 1, 2009. In June 2007, we paid OcuSense a total of $2,000,000 upon the attainment of the first of the two pre-defined milestones.

OcuSense is a San Diego-based company that is in the process of developing technologies that will enable eye care practitioners to test, at the point-of-care, for highly sensitive and specific biomarkers using nanoliters of tear film. The results of OcuSense’s operations have been included in our consolidated financial statements since November 30, 2006. OcuSense’s first product, which is currently under development, is a hand-held tear film test for the measurement of osmolarity, a quantitative and highly specific biomarker that has shown to correlate with dry eye disease, or DED. The test is known as the TearLab™ test for DED. The anticipated innovation of the TearLab™ test for DED will be its ability to measure precisely and rapidly certain biomarkers in nanoliter volumes of tear samples, using inexpensive hardware. Historically, eye care researchers have relied on expensive instruments to perform tear biomarker analysis. In addition to their cost, these conventional systems are slow, highly variable in their measurement readings and not categorized as waived by the FDA under the regulations promulgated under the Clinical Laboratory Improvement Amendments, or CLIA.

OcuSense is a variable interest entity in accordance with FIN 46(R) and OccuLogix is the primary beneficiary. Under FIN 46(R), assets, liabilities and non-controlling interest shall be measured at their fair value at the time of acquisition.

Assets acquired and liabilities assumed consisted solely of working capital and of a technology intangible asset relating to patents owned by OcuSense. Before consideration of deferred tax, the fair value of the assets acquired was greater than the fair value of the liabilities assumed and the non-controlling interest. Because OcuSense does not comprise a business, as defined in EITF 98-3 “Determining Whether a Nonmonetary Transaction Involves Receipt of Productive Assets or of a Business”, we applied the simultaneous equation method as per EITF 98-11 “Accounting for Acquired Temporary Differences in Certain Purchase Transactions That Are Not Accounted for as Business Combinations”, and adjusted the assigned value of the non-monetary assets acquired (consisting solely of the technology asset) to include the deferred tax liability.

The fair values of OcuSense’s assets, liabilities and minority interest, at the date of acquisition, were as follows:

	As at November 30
	2006

Net tangible assets	$	2,690,316
Intangible assets	$	12,895,388
Deferred_taxes	$	(5,158,155	)
Minority interest	$	(6,256,451	)
	$	4,171,098

On November 30, 2006, we announced that Elias Vamvakas, our Chairman and Chief Executive Officer, had agreed to provide us with a standby commitment to purchase convertible debentures of Occulogix (“Convertible Debentures”) in an aggregate maximum amount of $8,000,000 (the “Total Commitment Amount”). Pursuant to the Summary of Terms and Conditions, executed and delivered as of November 30, 2006 by Occulogix and Mr. Vamvakas, during the 12-month commitment term commencing on November 30, 2006, upon no less than 45 days’ written notice by the Company to Mr. Vamvakas, Mr. Vamvakas was obligated to purchase Convertible Debentures in the aggregate principal amount specified in such written notice. A commitment fee of 200 basis points was payable by the Company on the undrawn portion of the total $8,000,000 commitment amount. Any Convertible Debentures purchased by Mr. Vamvakas would have carried an interest rate of 10% per annum and would have been convertible, at Mr. Vamvakas’ option, into shares of our common stock at a conversion price of $2.70 per share. The Summary of Terms and Conditions of the standby commitment further provided that if the Company closed a financing with a third party, whether by way of debt, equity or otherwise and there are no Convertible Debentures outstanding, then, the Total Commitment Amount was to be reduced automatically upon the closing of the financing by the lesser of: (i) the Total Commitment Amount; and (ii) the net proceeds of the financing. On February 6, 2007, the Company raised gross proceeds in the amount of $10,016,000 in a private placement of shares of its common stock and warrants. The Total Commitment Amount was therefore reduced to zero, thus effectively terminating Mr. Vamvakas’ standby commitment. No portion of the standby commitment was ever drawn down by the Company, and the Company paid Mr. Vamvakas a total of $29,808 in commitment fees in February 2007.

Our results of operations for the years ended December 31, 2007 and 2006 were impacted by our adoption of Statement of Financial Accounting Standards (“SFAS”) No. 123R (revised 2004), “Share-Based Payments” (“SFAS No. 123R”), on January 1, 2006 which requires us to recognize a non-cash expense related to the fair value of our stock-based compensation awards. We elected to use the modified prospective transition method of adoption requiring us to include this stock-based compensation charge in our results of operations beginning on January 1, 2006 without restating prior periods to include stock-based compensation expense. Of the $480,971, $2,127,043 and $224,776 stock-based compensation expense recognized during the years ended December 31, 2007, 2006 and 2005, $65,660, $1,396,609 and $170,576 is included in general and administrative expenses, $216,246, $203,131 and $53,700 in clinical and regulatory expenses and $199,065, $527,303 and $500 in sales and marketing expenses, respectively.

At the annual meeting of stockholders of we held on June 23, 2006, our stockholders approved the re-pricing of all then out-of-the-money stock options of Occulogix. Consequently, the exercise price of all outstanding stock options that, on June 23, 2006, was greater than $2.05, being the weighted average trading price of our common stock on NASDAQ during the five-trading day period immediately preceding June 23, 2006, was adjusted downward to $2.05. 2,585,000 of the outstanding stock options with a weighted average exercise price of $8.42 were affected by the re-pricing. SFAS No. 123R treats the re-pricing of equity awards as a modification of the original award and provides that such a modification is an exchange of the original award for a new award. SFAS No. 123R considers the modification to be the repurchase of the old award for a new award of equal or greater value, incurring additional compensation cost for any incremental value. This incremental difference in value is measured as the excess, if any, of the fair value of the modified award determined in accordance with the provisions of SFAS No. 123R over the fair value of the original award immediately before its terms are modified, measured based on the share price and other pertinent factors at that date. SFAS No. 123R provides that this incremental fair value, plus the remaining unrecognized compensation cost from the original measurement of the fair value of the old option, must be recognized over the remaining vesting period. Of the 2,585,000 options affected by the re-pricing, 1,401,073 were vested as at December 31, 2006. Therefore, additional compensation cost of $423,338 for the 1,401,073 options was recognized and is included in the stock-based compensation expense for the year ended December 31, 2006.

In accordance with SFAS No. 123R, we also recorded a compensation expense of $3,363 in the second quarter of fiscal 2006 as our board of directors approved accelerating the vesting of 1,250 unvested stock options granted to a terminated employee on April 28, 2006. SFAS No. 123R treats such a modification as a cancellation of the original unvested award and the grant of a new fully vested award as of that date.

Prior to the adoption of SFAS No. 123R, we applied the provisions of SFAS No. 123, “Accounting for Stock-Based Compensation” (“SFAS No. 123”), which allowed companies either to expense the estimated fair value of employee stock options or to follow the intrinsic value method set forth in Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB No. 25”), but required companies to disclose the pro forma effects on net loss as if the fair value of the options had been expensed. We elected to apply APB No. 25 in accounting for employee stock options. As required by SFAS No. 123, prior to the adoption of SFAS No. 123R, we provided pro forma net loss and pro forma net loss per share disclosures for stock-based awards as if the fair value of the options had been expensed.

As at December 31, 2007, $3,870,931 of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 1.85 years.

On February 1, 2007, we entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with certain institutional investors, pursuant to which we agreed to issue to the investors an aggregate of 6,677,333 shares of our common stock (the “Shares”) and five-year warrants exercisable into an aggregate of 2,670,933 shares of our common stock (the “Warrants”). The per share purchase price of the Shares is $1.50, and the per share exercise price of the Warrants is $2.20, subject to adjustment. The Warrants became exercisable on August 6, 2007. Pursuant to the Securities Purchase Agreement, on February 6, 2007, we issued the Shares and the Warrants. The gross proceeds of sale of the Shares and the Warrants totaled $10,016,000 (less transaction costs of $871,215). On February 6, 2007, we also issued to Cowen and Company, LLC a five-year warrant exercisable into an aggregate of 93,483 shares of our common stock (the “Cowen Warrant”) in part payment of the placement fee payable to Cowen and Company, LLC for the services it had rendered as the placement agent in connection with the sale of the Shares and the Warrants. All of the terms and conditions of the Cowen Warrant (other than the number of shares of our common stock into which it is exercisable) are identical to those of the Warrants. The estimated grant date fair value of the Cowen Warrant of $97,222 is included in the transaction cost of $871,215.

We account for the Warrants and the Cowen Warrant in accordance with the provisions of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” (“SFAS No. 133”) along with related interpretation Emerging Issues Task Force (“EITF”) 00-19 “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock” (“EITF 00-19”). SFAS No. 133 requires every derivative instrument within its scope (including certain derivative instruments embedded in other contracts) to be recorded on the balance sheet as either an asset or liability measured at its fair value, with changes in the derivative’s fair value recognized currently in earnings unless specific hedge accounting criteria are met. Based on the provisions of EITF 00-19, we determined that the Warrants and the Cowen Warrant do not meet the criteria for classification as equity. Accordingly, we have classified the Warrants and the Cowen Warrant as a current liability as of December 31, 2007. The estimated fair value of the Warrants and the Cowen Warrant was determined using the Black-Scholes options pricing model. We initially allocated the total proceeds received, pursuant to the Securities Purchase Agreement, to the Shares and the Warrants based on their relative fair values. This resulted in an allocation of $2,052,578 to the obligation under warrants which includes the fair value of the Cowen Warrant of $97,222. SFAS No. 133 also requires Occulogix to record the outstanding derivatives at fair value at the end of each reporting period resulting in an adjustment to the recorded liability of the derivative, with any gain or loss recorded in earnings of the applicable reporting period. We therefore estimated the fair value of the Warrants and the Cowen Warrant as at December 31, 2007 and determined the aggregate fair value to be a nominal amount, a decrease of approximately $2,052,578 over the initial measurement of the aggregate fair value of the Warrants and the Cowen Warrant on the date of issuance. Accordingly, we recognized a gain of $2,052,578 in the Company's consolidated statements of operations for the year ended December 31, 2007 to reflect thedecrease in our obligation to its warrant holders to a nominal amount at December 31, 2007. Transaction costs associated with the issuance of the Warrants of $170,081 was recorded as an expense in the Company's consolidated statement of operations for the year ended December 31, 2007.

On March 11, 2007, our Board of Directors approved the grant to the directors of the Company, other than Mr. Vamvakas, of a total of 165,000 options under the 2002 Stock Option Plan. In exchange for these options, each of the directors of the Company will forego the cash remuneration which he or she would have been entitled to receive from us during the financial year ending December 31, 2007 in respect of (i) his or her annual director's fee of $15,000, (ii) in the case of those directors who chair a committee of the board of directors of the Company, his or her fee of $5,000 per annum for chairing such. committee and (iii) his or her fee of $2,500 per fiscal quarter for the quarterly in-person meetings of the board of directors of the Company. The number of options granted to each of the directors was determined to be 8% higher in value than the cash remuneration to which the directors would have been entitled during the financial year ending December 31, 2007 and was determined using the Black-Scholes option pricing model.. The number of options granted to each director, calculated using this methodology, was then rounded up to the nearest 1,000. These options are exercisable immediately and will remain exercisable until the tenth anniversary of the date of their grant, notwithstanding any earlier disability or death of the holder thereof or any earlier termination of his or her service to the Company. The exercise price of each option is set at $1.82, which was the per share closing price of the Company's common stock on NASDAQ on March 9, 2007, the last trading day prior to the date of grant.

On May 30, 2007, TLC Vision Corporation (“TLC Vision”) and JEGC OCC Corp. (“JEGC”) announced that JEGC had agreed to purchase TLC Vision’s ownership stake in the Company, subject to certain minimum prices and regulatory limitations and further subject to JEGC obtaining satisfactory financing and other customary closing conditions. On June 22, 2007, JEGC purchased a portion of TLC Vision’s ownership stake in the Company, consisting of 1,904,762 shares, at a price of $1.05 per share. On July 3, 2007, we announced that we had entered into discussions with JEGC for the private placement of approximately $30,000,000 of shares of our common stock at a price based upon the average trading price at the time of purchase, subject to compliance with regulatory requirements and to a minimum purchase price of $1.05 per share. On October 15, 2007, TLC Vision announced that JEGC was not able to complete the purchase of TLC Vision’s remaining ownership stake in the Company by October 12, 2007, being the deadline previously agreed by TLC Vision and JEGC. In making that announcement, TLC Vision also stated that JEGC retains a non-exclusive right to purchase TLC Vision’s remaining ownership stake in the Company, subject to the right of each of TLC Vision and JEGC to terminate the agreement between them. It was anticipated that JEGC would have gained a control position in the Company, if both of these transactions had been completed. Our discussions with JEGC have not resulted in any agreement. JEGC is owned by Jefferson EquiCorp Ltd. and by Greybrook Corporation, a firm controlled by Mr. Vamvakas.

As at December 31, 2007, we had investments in the aggregate principal amount of $1,900,000 which consist of investments in four separate asset-backed auction rate securities yielding an average return of 5.865% per annum. However, as a result of market conditions, all of these investments have recently failed to settle on their respective settlement dates and have been reset to be settled at a future date with an average maturity of 46 days. Due to the current lack of liquidity for asset-backed securities of this type, we concluded that the carrying value of these investments was higher than its fair value as of December 31, 2007. Accordingly, these auction rate securities have been recorded at their estimated fair value of $863,750. We consider this to be an other-than-temporary reduction in the fair value of these auction rate securities. Accordingly, the loss associated with these auction rate securities of $1,036,250 has been included as an impairment of investments in our consolidated statement of operations for the year ended December 31, 2007. Although we continue to receive payment of interest earned on these securities, we do not know at the present time when it will be able to convert these investments into cash. Accordingly, management has classified these investments as a non-current asset on its consolidated balance sheet as of December 31, 2007. Management will continue to closely monitor these investments for future indications of further impairment. The illiquidity of these investments may have an adverse impact on the length of time during which we currently expect to be able to sustain its operations in the absence of an additional capital raise by the Company.

On September 18, 2007, OccuLogix received a letter from The Nasdaq Stock Market, or Nasdaq, indicating that, for the previous 30 consecutive business days, the bid price of the Company's common stock closed below the minimum $1.00 per share requirement for continued inclusion under Marketplace Rule 4450(e)(5), or the Minimum Bid Price Rule. Therefore, in accordance with Marketplace Rule 4450(e)(2), the Company were provided 180 calendar days, or until March 17, 2008, to regain compliance. The Nasdaq letter stated that, if, at any time before March 17, 2008, the bid price of the Company's common stock closes at $1.00 per share or more for a minimum of 10 consecutive business days, Nasdaq staff will provide written notification that it has achieved compliance with the Minimum Bid Price Rule. The Nasdaq letter also stated that, if the Company do not regain compliance with the Minimum Bid Price Rule by March 17, 2008, Nasdaq staff will provide written notification that the Company's securities will be delisted, at which time the Company may appeal the Nasdaq staff’s determination to delist its securities to a Nasdaq Listing Qualifications Panel.

On February 1, 2008, OccuLogix received a letter from Nasdaq indicating that, for the previous 30 consecutive trading days, our common stock did not maintain a minimum market value of publicly held shares of $5,000,000 as required for continued inclusion by Marketplace Rule 4450(a)(2), or the MVPHS Rule. Therefore, in accordance with Marketplace Rule 4450(e)(1), we were provided 90 calendar days, or until May 1, 2008, to regain compliance. The Nasdaq letter stated that, if at any time before May 1, 2008, the minimum market value of publicly held shares of the Company's common stock is $5,000,000 or greater for a minimum of ten consecutive trading days, Nasdaq staff will provide written notification that we comply with the MVPHS Rule. The Nasdaq letter also stated that, if the Company does not regain compliance with the MVPHS Rule by May 1, 2008, Nasdaq staff will provide written notification that the Company's securities will be delisted, at which time the Company may appeal the Nasdaq staff’s determination to delist its securities to a Nasdaq Listing Qualifications Panel.

We will not have become compliant with the Minimum Bid Price Rule by March 17, 2008. Although we intend to appeal any determination by Nasdaq staff to delist our common stock to a Nasdaq Listing Qualifications Panel, we may not be successful in our appeal, in which case our common stock may be transferred to The Nasdaq Capital Market or be delisted altogether. Should either occur, existing stockholders will suffer decreased liquidity.

These Nasdaq notices have no effect on the listing of the Company's common stock on the Toronto Stock Exchange.

Recent Developments

On February 19, 2008, we announced that the Company had secured a bridge loan in an aggregate principal amount of $3,000,000, less transaction costs of approximately $200,000, from a number of private parties. The loan bears interest at a rate of 12% per annum and has a 180-day term, which may be extended to 270 days under certain circumstances. The repayment of the loan is secured by a pledge by the Company of its shares of the capital stock of OcuSense. Under the terms of the loan agreement, the Company have two pre-payment options available to it, should it decide to not wait until the maturity date to repay the loan. Under the first pre-payment option, the Company may repay the loan in full by paying the lenders, in cash, the amount of outstanding principal and accrued interest and issuing to the lenders five-year warrants in an aggregate amount equal to approximately 19.9% of the issued and outstanding shares of the Company's common stock (but not to exceed 20% of the issued and outstanding shares of the Company's common stock). The warrants would be exercisable into shares of the Company's common stock at an exercise price of $0.10 per share and would not become exercisable until the 180th day following their issuance. Under the second pre-payment option, provided that the Company have closed a private placement of shares of its common stock for aggregate gross proceeds of at least $4,000,000, we may repay the loan in full by issuing to the lenders shares of its common stock, in an aggregate amount equal to the amount of outstanding principal and accrued interest, at a 15% discount to the price paid by the private placement investors. Any exercise by the Company of the second pre-payment option would be subject to stockholder and regulatory approval.

Currently, we anticipate that the net proceeds of the loan, together with the Company's other cash and cash equivalents, will be sufficient to sustain the Company's operations only until approximately the end of April 2008 (assuming that the outstanding obligation of OccuLogix to pay $2,000,000 to OcuSense becomes due and payable prior to the end of April 2008).

RESULTS OF OPERATIONS

Restatement of Consolidated Financial Statements

A. Correction of an error related to the method of consolidation of OcuSense Inc.

Background Information

On November 30, 2006, OccuLogix acquired 1,754,589 Series A preferred shares of OcuSense Inc. (“OcuSense”). The purchase price of these shares was made up of two fixed payments of $2.0 million each to be made on the date of the closing of the transaction (i.e. November 30, 2006) and on January 3, 2007. In addition, subject to OcuSense achieving certain milestones, the Company were required to pay two additional milestone payments of $2.0 million each.

Upon acquiring the Series A preferred shares, OccuLogix and certain founding stockholders entered into a voting agreement. The voting agreement provides the founding stockholders of OcuSense, as defined in the voting agreement, with the right to appoint two board members and OccuLogix with the right to also appoint two directors. A selection of a fifth director is mutually agreed upon by both OccuLogix and the founding stockholders, each voting as a separate class. The voting agreement is subject to termination under the following scenarios: a) a change of control; b) majority approval of each of OccuLogix and the founding stockholders; and c) conversion of all of the preferred shares to common shares. OccuLogix has the ability to force the conversion of all outstanding shares of OcuSense's Preferred stock to shares of common stock and thus has the ability to effect a termination of the voting agreement, but this would require conversion of its own preferred shares and the relinquishment of the rights and obligations associated with outstanding preferred shares.

The principal rights associated with of the Series A Preferred Stock are as follows:

·	Voting – Holders of the Series A preferred shares are entitled to vote on an as-converted basis. Each Series A preferred share is entitled to one vote per share.

·	Conversion features – Series A preferred shares are convertible to common shares on a one-for-one basis at the option of the holder.

·	Dividends – The preferred shares are entitled to non-cumulative dividends at 8%, and additional dividends would be shared between common and preferred shares on a per-share basis.

·	Redemption features – Subsequent to November 30, 2011, the preferred shares may be redeemed, at the option of the holder, at the higher of the original issue price and the fair market value of the common shares into which the preferred shares could be converted, subject to available cash.

·	Liquidation preferences – Series A preferred shares have a liquidation preference over OcuSense's common shares up to the original issue price of the preferred shares (including the milestone payments).

Immediately after the OccuLogix investment in OcuSense, OcuSense had the following capital structure:

Description	Number
Common shares		1,222,979
Series A preferred shares – OccuLogix		1,754,589
Series A preferred shares – Other unrelated parties		67,317
Total		3,044,885

Potentially dilutive instruments
Warrants		89,965
Stock Options		367,311
Fully Diluted		3,502,161

Based on the above capital structure, on a fully diluted basis, OccuLogix’s voting percentage was determined to be 50.1%. On a current voting basis, OccuLogix’s voting interest is 57.62%. We previously consolidated OcuSense based on an ownership percentage of 50.1%.

Interpretation and Related Accounting Treatment

Since November 30, 2006, the date of the acquisition, we have consolidated OcuSense on the basis of a voting control model, as a result of the fact that we own more than 50% of the voting stock of OcuSense and that we had the ability to convert our Series A preferred shares into common shares, which would result in the termination of the voting agreement between the founders and OccuLogix and which would result in our gaining control of the board of directors.

However, after further consideration the Company has now determined that, as a result of the voting agreement between us and the founding stockholders of OcuSense, we are not able to exercise voting control as contemplated in ARB 51 “Consolidated Financial Statements” (“ARB 51”) unless the Company converts its Series A preferred shares of OcuSense. For purposes of assessing voting control in accordance with ARB 51, US GAAP does not take into consideration such conversion rights. Accordingly we do not have the ability to exercise control of OcuSense in light of the voting agreement that currently exists between the founding shareholders and us.

In addition to the above consideration, we also determined that OcuSense is a Variable Interest Entity and that we are the primary beneficiary based on the following:

·	OcuSense is a development stage enterprise (as defined under FAS 7, “Accounting and Reporting by Development Stage Enterprises”) and therefore is not considered to be a business under U.S. GAAP. Accordingly, OcuSense is not subject to the business scope exception.

·	We noted that the holders of the Series A preferred shares (including us) have the ability to redeem their shares at the greater of their original subscription price and their fair value on an as-converted basis. As such, their investment is not considered to be at-risk equity.

Additionally, as a result of the voting agreement between us and the founding shareholders of OcuSense, voting control of OcuSense is shared between us and OcuSense. Accordingly, the common shareholders, who represent the sole class of at-risk equity, cannot make decisions about an entity’s activities that have a significant effect on the success of the entity without our concurrence.

FIN 46(R) requires that the enterprise which consolidates the variable interest entity be the primary beneficiary of that entity. The primary beneficiary is the entity that will absorb a majority of the variable interest entity’s expected losses, receive a majority of the entity’s expected returns, or both. Since the date of acquisition of the Shares, the purchase price therefore (including the two additional milestone payments) has constituted virtually the entire source of funding of OcuSense. The common shareholders were expected to make nominal equity contributions during this period. Therefore, based primarily on qualitative considerations, we believe that we are the primary beneficiary of OcuSense and should consolidate OcuSense using the variable interest model.

The Company have noted that the initial measurement of assets, liabilities and non-controlling interests under FIN 46(R) differs from that which is required under FAS 141 “Business Combinations”. In particular, under FIN 46(R), assets, liabilities and non-controlling interest shall be measured initially at their fair value. The Company previously recorded the non-controlling interest based on the historical carrying values of OcuSense’s assets and liabilities and, as a result, consolidation under FIN 46(R) has resulted in material revisions to the amounts previously reported in the consolidated financial statements.

Assets acquired and liabilities assumed consisted primarily of working capital and of a technology intangible asset relating to patents owned by OcuSense. Before consideration of deferred tax, the fair value of the assets acquired will be greater than the fair value of the liabilities assumed and the non-controlling interest. Because OcuSense does not comprise a business, as defined in EITF 98-3 “Determining Whether a Nonmonetary Transaction Involves Receipt of Productive Assets or of a Business”, the Company applied the simultaneous equation method as per EITF 98-11 “Accounting for Acquired Temporary Differences in Certain Purchase Transactions That Are Not Accounted for as Business Combinations”, and adjusted the assigned value of the non-monetary assets acquired (consisting solely of the technology asset) to include the deferred tax liability.

The Company also considered the appropriate accounting for the milestone payments, as a result of the fact that it has determined that it should apply the initial measurement guidance in FIN 46(R). The Company note that subsequent to initial consolidation, the milestone payment liability represents a contingent liability to a controlled subsidiary, and as such, the liability eliminates on consolidation. Previously, the Company adjusted the minority interest at the date of each milestone payment to reflect the non-controlling interest’s share in the additional cash of the subsidiary, with an offsetting increase to the non-monetary assets acquired (consisting solely of the technology intangible asset) reflecting the increased actual cost of obtaining those non-monetary assets.

The Company note that because the non-controlling interest is required to be measured at fair value on acquisition of OcuSense, the fair value of the milestone payments as of the date of acquisition will be embedded in the initial measurement of non-controlling interest. As such, it would be inappropriate to record additional minority interest based on the full amount of the milestone payment applicable to the minority interest. Accordingly, the Company have accounted for the milestone payments as follows:

We determined the fair value of the milestone payments on the date of acquisition, by incorporating the probability that the milestone payments will be made, as well as the time value associated with the planned settlement date of the payments.

Upon payment of the milestone payments, we recorded the minority interest portion of the change in fair value of the milestone payment (i.e. the minority interest portion of the ultimate value of the milestone payment less the initial fair value determination) as an expense, with a corresponding increase to minority interest, to reflect the additional value provided to the minority interest in excess of that contemplated on the acquisition date.

The following is a summary of the significant effects of the restatements on our consolidated balance sheets as of December 31, 2007 and 2006 and its consolidated statements of operations and cash flows for the fiscal years ended December 31, 2007 and 2006.

(1) Amounts reflect correction of prior year’s amounts related to stock options granted to consultants as noted below.

B.	Correction of prior years’ comparative amounts

In accordance with the Securities and Exchange Commission (the “SEC”) Staff Accounting Bulletin (“SAB”) No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements”, the following discussion on the Company's results of operations have been corrected to reflect the Company's accounting for stock options granted during fiscal 2005 to certain consultants that were subject to performance conditions. The vesting of these options was contingent upon the attainment of FDA approval of the RHEO™ System. These stock options were accounted for in accordance with SFAS No. 123 and subsequently in accordance with SFAS No. 123(R) upon the Company's adoption of SFAS No. 123(R) on January 1, 2006. The total fair value of these options was estimated at the date of grant and was being amortized, over the Company's estimate of the expected vesting period, as stock-based compensation expense in our consolidated statements of operations. In preparing the financial statements for the year ended December 31, 2007, the Company noted that these options should have been accounted for in accordance with EITF 96-18, Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services, (“EITF 96-18”) which requires that if, on the measurement date of the award, the quantity or any of the terms of the equity instruments are dependent on the achievement of performance conditions which result in a range of fair values, the lowest aggregate amount should be used.

Based on the provisions of EITF 96-18, the Company concluded that no stock-based compensation expense should have been recorded for these options. Since the effect of the error on the individual prior periods’ consolidated financial statements was immaterial, the Company have adjusted the comparative consolidated financial statements of prior years to reflect the correction of this error without undertaking a restatement of the prior periods’ consolidated financial statements. The following financial statement line items for fiscal 2006 and 2005 were affected by the correction of the error.

Revenues

Revenue consists of revenue generated from the sale of components of the RHEO™ System which consists of the OctoNova pump and the disposable treatment sets, which include two disposable filters and applicable tubing.

During the year ended December 31, 2007, we sold a total of 816 treatment sets, at a price of $200 per treatment set, to Veris. The sale of these treatment sets was not recognized as revenue during the year based on Veris’ payment history with us and the 180-day payment terms agreed by Veris and us in March 2007. In October 2007, we met with the management of Veris and based on discussions with Veris, we believe that Veris will not be able to meet its financial obligations to us. Therefore, during the year ended December 31, 2007, the Company recorded an allowance for doubtful accounts against the total amount due from Veris for the purchase of the treatment sets.

Revenues for the year ended December 31, 2007 is made up of revenue from the sale of a total of 600 treatment sets at a negotiated price of $150 per treatment set to Macumed AG, a company based in Germany. Revenues for the year ended December 31, 2006 include the sale of 859 treatment sets to Veris at a negotiated price of $200 per treatment set as payment was received by us in advance of shipment of the treatment sets.

During fiscal 2006, as compared with fiscal 2005, revenues decreased significantly primarily due to reduced sales of components of the RHEO™ System to Veris as a result of our February 3, 2006 announcement that MIRA-1 did not meet its primary efficacy endpoint. In addition, included in revenues in fiscal 2005 are sales made to RHEO Clinic Inc., a subsidiary of TLC Vision Corporation (“TLC Vision”) and a related party, for which we reported revenues of $81,593 in the period. RHEO Clinic Inc. has since ceased the treatment of commercial patients and is therefore no longer a source of revenue for us.

On November 1, 2007, we announced an indefinite suspension of the RHEO™ System clinical development program for Dry AMD and are in the process of winding down the RHEO-AMD study. Accordingly, we do not expect to be able to continue to generate revenue from the sale of the components of the RHEO™ System in the future.

Cost of Sales

Cost of sales includes costs of goods sold and royalty costs. Our cost of goods sold consists primarily of costs for the manufacture of the RHEO™ System, including the costs we incur for the purchase of component parts from our suppliers, applicable freight and shipping costs, fees related to warehousing, logistics inventory management and recurring regulatory costs associated with conducting business and ISO certification.

During fiscal 2006, we sold a number of treatment sets to Veris at a price, net of negotiated discounts, which was lower than our cost. As Veris was then our sole customer for the RHEO™ System treatment sets, the price at which we sold the treatment sets to Veris represented our inventory’s then current net realizable value, and therefore, we have written down the value of the treatment sets to reflect this net realizable value. Included in cost of sales for the year ended December 31, 2006, is $1,625,000 which reflects the write-down of the treatment sets to its net realizable value. In addition, we evaluated our ending inventories as at December 31, 2006 on the basis that Veris may not be able to increase its commercial activities in Canada in line with our initial expectations. Accordingly, we set up an additional provision for obsolescence of $1,679,124 during the year ended December 31, 2006 for treatment sets that will unlikely be utilized prior to their expiration dates (2005 - $1,990,830). As at December 31, 2006, the value of our commercial inventory of treatment sets was nil. On November 1, 2007, we announced an indefinite suspension of the RHEO™ System clinical development program for Dry AMD, and we are engaged in the process of winding down the RHEO-AMD study. Accordingly, we have written down the value of our commercial inventory of OctoNova pumps to nil as of December 31, 2007 since the Company may not be able to sell or utilize these pumps before their technologies become outdated. Included in cost of sales for the year ended December 31, 2007, is a charge of $2,190,666 which reflects the write-down of the value of these pumps to nil as of December 31, 2007.

Cost of sales for the year ended December 31, 2007 includes royalty fees payable to Dr. Brunner and Mr. Stock and a charge of $2,190,666 which reflects the write-down of the value of our commercial inventory of pumps to nil as of December 31, 2007. Included in cost of sales for the year ended December 31, 2006 are royalty fees payable to Dr. Brunner and Mr. Stock and a total charge of $3,304,124 which reflect the write-down of our commercial inventory of treatment sets to nil as at December 31, 2006.

During the year ended December 31, 2006, as compared with the corresponding period in fiscal 2005, cost of sales increased due primarily to the charge of $1,625,000 which reflects the write-down of our inventory of treatment sets to its net realizable value. There was no comparative expense in fiscal 2005. Cost of sales for the years ended December 31, 2006 and 2005 includes a provision for obsolescence of $1,679,124 and 1,990,830, respectively, for treatment sets that will unlikely be utilized prior to their expiration dates.

Gross Margin

During fiscal 2007 as compared with fiscal 2006, our retina gross margin decreased 579 percentage points due to reduced sales in fiscal 2007.

During fiscal 2006 as compared with fiscal 2005, our retina gross margin decreased 1,844 percentage points due to reduced sales in fiscal 2006 and increased cost of sales due to the inventory write-down and the provision for obsolescence recorded in the period.

General and Administrative Expenses

General and administrative expenses decreased by $371,346 during the year ended December 31, 2007, as compared with the corresponding period of fiscal 2006 due to a decrease of $1,352,416 in stock-based compensation expense which reflects the reversal of the stock-based compensation expense recorded in prior periods associated with performance-based options granted to certain of our employees, directors and consultants. The vesting of these options was contingent upon meeting company-wide goals which include the attainment of FDA approval of the RHEO™ System and the achievement of a minimum amount of sales over a specified period. In light of the indefinite suspension of the RHEO™ System clinical development program and the sale of SOLX, management concluded that these goals were no longer achievable and accordingly has reversed the option expense recorded in prior periods associated with these performance-based options.

Included within general and administrative expense are professional fees which decreased by $352,634 during the year ended December 31, 2007 as compared with the corresponding period of fiscal 2006. These decreases were partially offset by the increase in employee and related travel costs of $383,859 due to the additional cost of OcuSense employees during the period as well as the increase in amortization expense of $1,182,077 associated with the intangible asset acquired upon the acquisition of OcuSense on November 30, 2006. General and administrative expenses for the year ended December 31, 2007 also include a charge of $190,873 which reflects the reduction to the carrying value of certain of our patents and trademarks related to the RHEO™ System as a result of our indefinite suspension of the RHEO™ System clinical development program for Dry AMD. There was no comparative charge during the year ended December 31, 2006. The above decreases were partially offset by a net increase in amortization expense related to intangible assets by $730,679. As previously discussed, the increase in amortization expense is attributed to a higher intangible asset value arising from the fair value adjustments associated with consolidating OcuSense as a variable interest entity on the date of acquisition.

General and administrative expenses decreased by $194,643 during the year ended December 31, 2006, as compared with the corresponding period of fiscal 2005. This decrease is due to the decrease in employee and related travel costs of $537,274 due in part to the grant of options to an employee in lieu of salary. Professional fees and fees associated with compliance with Section 404 of the Sarbanes-Oxley Act of 2002 also decreased by $917,318 while directors’ fees decreased by $50,207 due to the grant of options to directors in lieu of their annual fees payable for board and committee memberships. These decreases in cost were partially offset by an increase of $1,262,292 in stock-based compensation expense associated with the adoption of SFAS No. 123R on January 1, 2006 which requires us to recognize a non-cash expense related to the fair value of our stock-based compensation awards. In addition, included within general and administrative expense for the year ended December 31, 2006 is $68,250 in additional amortization expense related to the accounting for OcuSense as a variable interest entity since the date of acquisition on November 30, 2006. There was no similar amounts in prior periods.

We are continuing to focus our efforts on achieving additional operating efficiencies by reviewing and improving upon our existing business processes and cost structure..

Clinical and Regulatory Expenses

Clinical and regulatory expenses increased by $3,753,781 during the year ended December 31, 2007, as compared with the corresponding prior year period, due to the increase in OcuSense product development and regulatory costs of $2,564,703. OcuSense employee and related travel costs, professional fees and options expense also increased by $494,458, $328,713 and $112,360, respectively, during the year ended December 31, 2007 as compared with the corresponding period in fiscal 2006. We acquired 50.1% of the capital stock, on a fully diluted basis, 57.62% on an issued and outstanding basis, of OcuSense on November 30, 2006. Therefore, clinical and regulatory expenses for the year ended December 31, 2006 include OcuSense’s cost for the month of December 2006. Clinical trial expenses associated with the RHEO-AMD trial also increased by $1,101,074. The RHEO-AMD trial was abandoned on November 1, 2007. Accordingly, we have recorded a write-down to the value of our inventory of treatment sets used for the trial and also written down the carrying value of certain of our medical equipment used in the trial. Clinical and regulatory expenses for the year ended December 31, 2007 therefore include a charge of $942,309 which reflects the write-down of our inventory and certain of our medical equipment as of December 31, 2007. Also included in clinical trial expenses for the year ended December 31, 2006 are advance payments totaling $243,644 made to various clinical trial sites for the provision of clinical trial services in connection with our RHEO-AMD trial which we have abandoned. This unrecoverable amount has been fully expensed in the year ended December 31, 2007. There was no comparative expense during the year ended December 31, 2006. These increases in cost during the year ended December 31, 2007 were offset in part by the decrease in costs associated with the MIRA-1 trial, the LEARN, or Long-term Efficacy in AMD from Rheopheresis in North America, trials and other related clinical trials of $2,200,131 since the Company completed the analysis of the MIRA-1 data during the first half of fiscal 2006 and the treatment phase of the LEARN trials was completed in December 2006.

During the year ended December 31, 2006, clinical and regulatory expenses decreased by $245,778, as compared with the corresponding period in fiscal 2005, as a result of decreased professional fees associated with the MIRA-1 clinical trial of $233,920.

Our goal is to complete product development of OcuSense’s TearLab™ test for DED. Following the completion of product development, OcuSense will have to conduct clinical trials in order to seek a 510(k) clearance and a CLIA waiver from the FDA for the TearLab™ test for DED.

Sales and Marketing Expenses

Sales and marketing expenses decreased by $211,729 during the year ended December 31, 2007, as compared with the prior period in fiscal 2006, due to the decrease in the RHEO™ System marketing expenses of $128,420. Stock-based compensation expense also decreased by $331,038 which reflects the reversal of the stock-based compensation expense recorded in prior periods associated with performance-based options granted to certain of our employees, directors and consultants. The vesting of these options was contingent upon meeting company-wide goals which include the attainment of FDA approval of the RHEO™ System and the achievement of a minimum amount of sales over a specified period. In light of the indefinite suspension of the RHEO™ System clinical development program and the sale of SOLX, management concluded that these goals were no longer achievable and accordingly has reversed the option expense recorded in prior periods associated with these performance-based options. These decreases in cost were offset in part by the increase in OcuSense employee and related travel costs of $146,504 and professional fees of $61,559. During 2007, OcuSense hired a new employee and retained the use of some outside consultants to begin establishing sales and marketing efforts to increase awareness of the TearLab™ test for DED, and upon receipt of FDA approval, to promote the use of the TearLab™ test for DED in the United States.

Sales and marketing expenses decreased by $540,149 during the year ended December 31, 2006, as compared with the prior period in fiscal 2005, due to reduced employee and travel costs during the period of $422,423 and a decrease in marketing expenses of $344,067 due to reduced marketing efforts in the year following the announcement of MIRA-1 results. Bad debt expense also decreased during the year ended December 31, 2006 by $510,913 as we only recognized revenue on sale of treatment sets sold to its then sole customer, Veris, on receipt of payment. These decreases in costs were offset by increased stock-based compensation expense of $524,003 associated with the adoption of SFAS No. 123R beginning January 1, 2006 and increased fees and expenses of our Scientific Advisory Board members of $210,456.

The cornerstone of our sales and marketing strategy to date has been to increase awareness of our product among eye care professionals and, in particular, the key opinion leaders in the eye care professions. OcuSense will continue to develop and execute our conference and podium strategy to ensure visibility and evidence-based positioning of the TearLab™ test for DED among eye care professionals.

Impairment of Goodwill

The decrease in our stock price subsequent to the February 3, 2006 announcement of the MIRA-1 trial's failure to meet its primary efficacy endpoint, the June 12, 2006 announcement of the outcome of our meeting with the FDA and the June 30, 2006 announcement of the termination of negotiations with Sowood were identified as indicators of impairment which led to an analysis of our intangible assets and goodwill which, in turn, resulted in the reporting of an impairment charge of $65,946,686 and $147,451,758 during the years ended December 31, 2006 and 2005, respectively. The impairment of goodwill charge represents the write-down of the value of goodwill acquired on the purchase of TLC Vision's 50% interest in OccuLogix, L.P. on December 8, 2004 to nil as at December 31, 2006.

Impairment of Intangible Assets

Prior to the termination of the Distribution Agreement on February 25, 2008, the Company's intangible assets consisted of the value of that distribution agreement with Asahi Medical and the distribution agreement the Company have with Diamed and MeSys, the designer and the manufacturer, respectively, of the OctoNova pumps. The Rheofilter filter, the Plasmaflo filter and the OctoNova pump are components of the RHEO™ System. On November 1, 2007, the Company announced an indefinite suspension of the RHEO™ System clinical development program for Dry AMD and is in the process of winding down the RHEO-AMD study as there is no reasonable prospect that the RHEO™ System clinical development program will be relaunched in the foreseeable future. In accordance with SFAS No. 144, the Company concluded that its indefinite suspension of the RHEO™ System clinical development program for Dry AMD was a significant event which may affect the carrying value of its distribution agreements. Accordingly, management was required to re-assess whether the carrying value of the Company's distribution agreements was recoverable as of December 31, 2007. Based on management’s estimates of undiscounted cash flows associated with the distribution agreements, the Company concluded that the carrying value of the distribution agreements was not recoverable as of December 31, 2007. Accordingly, we recorded an impairment charge of $20,923,028 during the year ended December 31, 2007 to record the distribution agreements at their fair value as of December 31, 2007. There was no comparable expense during the years ended December 31, 2006 and 2005.

Restructuring Charges

In accordance with SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities” (“SFAS No. 146”), we recognized a total of $1,312,721 and $819,642 in restructuring charges during the years ended December 31, 2007 and 2006, respectively. With the suspension of the Company's RHEO™ System clinical development program, and the consequent winding-down of the RHEO-AMD study, and the Company's disposition of SOLX during the year ended December 31, 2007, we have reduced its workforce considerably. During 2006, the Company implemented a number of structural and management changes designed both to support the continued development of the RHEO™ System and to execute the Company's accelerated diversification strategy within ophthalmology. The restructuring charges of $1,312,721 and $819,642, recorded in the years ended December 31, 2007 and 2006, respectively, consist solely of severance and benefit costs related to the termination of certain of the Company's employees at the Company's Palm Harbor and Mississauga offices. The severance and benefit costs recorded during the year ended December 31, 2007 were yet to be paid by December 31, 2007. There was no comparable expense in the year ended December 31, 2005.

Interest Income

Interest income consists of interest income earned in the current period and the corresponding prior periods as a result of the Company's cash and short-term investment position following the raising of capital in the Company's initial public offering in December 2004 and in the private placement of the Shares and Warrants in February 2007.

The continued decrease in interest income during years ended December 31, 2007 and 2006, when compared to the corresponding period in fiscal 2005, is due to the utilization of the funds raised in order to finance infrastructure costs, to accumulate inventory and to fund costs of the MIRA-1 and RHEO-AMD trials and other clinical trials and, more recently, to acquire SOLX and OcuSense in line with our diversification strategy.

Changes in Fair Value of Warrant Obligation

On February 6, 2007, pursuant to the Securities Purchase Agreement between the Company and certain institutional investors, the Company issued the Warrants to these investors. The Warrants are five-year warrants exercisable into an aggregate of 2,670,933 shares of the Company's common stock. On February 6, 2007, the Company also issued the Cowen Warrant to Cowen and Company, LLC in part payment of the placement fee payable to Cowen and Company, LLC for the services it had rendered as the placement agent in connection with the private placement of the Shares and the Warrants. The Cowen Warrant is a five-year warrant exercisable into an aggregate of 93,483 shares of the Company's common stock. The per share exercise price of the Warrants is $2.20, subject to adjustment, and the Warrants became exercisable on August 6, 2007. All of the terms and conditions of the Cowen Warrant (other than the number of shares of the Company's common stock into which it is exercisable) are identical to those of the Warrants. The Company account for the Warrants and the Cowen Warrant in accordance with the provisions of SFAS No. 133 along with related interpretation EITF 00-19. Based on the provisions of EITF 00-19, the Company determined that the Warrants and the Cowen Warrant do not meet the criteria for classification as equity. Accordingly, the Company have classified the Warrants and the Cowen Warrant as a current liability as at December 31, 2007. The estimated fair value was determined using the Black-Scholes option-pricing model. In addition, SFAS No. 133 requires us to record the outstanding derivatives at fair value at the end of each reporting period resulting in an adjustment to the recorded liability of the derivative, with any gain or loss recorded in earnings of the applicable reporting period. The Company therefore estimated the fair value of the Warrants and the Cowen Warrant as at December 31, 2007 and determined the aggregate fair value to be a nominal amount, a decrease of approximately $2,052,578 over the initial measurement of the aggregate fair value of the Warrants and the Cowen Warrant on the date of issuance.

Changes in fair value of warrant obligation for the year ended December 31, 2007 includes a gain of $2,052,578 which reflect the decrease in the fair value of the Warrants and the Cowen Warrant at December 31, 2007 over their fair value on the date of issuance. Transaction costs associated with the issuance of the Warrants of $170,081 have also been recorded as a warrant expense in the Company's consolidated statement of operations for the year ended December 31, 2007. There was no comparable net gain recorded in the years ended December 31, 2006 and 2005.

Impairment of investments

Impairment of investments for the year ended December 31, 2007 reflect the decrease in the fair value of the Company's investments in asset-backed auction rate securities as at December 31, 2007. There was no comparable expense recorded in the years ended December 31, 2006 and 2005.

Interest Expense

On November 30, 2006, we announced that Elias Vamvakas, our Chairman and Chief Executive Officer, had agreed to provide us with a standby commitment to purchase Convertible Debentures of the Company for a Total Commitment Amount of $8,000,000. Pursuant to the Summary of Terms and Conditions, during the 12-month commitment term commencing on November 30, 2006, upon no less than 45 days’ written notice by us to Mr. Vamvakas, Mr. Vamvakas was obligated to purchase Convertible Debentures in the aggregate principal amount specified in such written notice. A commitment fee of 200 basis points was payable by us on the undrawn portion of the total $8,000,000 commitment amount. Any Convertible Debentures purchased by Mr. Vamvakas would have carried an interest rate of 10% per annum and would have been convertible, at Mr. Vamvakas’ option, into shares of the Company's common stock at a conversion price of $2.70 per share. The Summary of Terms and Conditions of the standby commitment further provided that if the Company closed a financing with a third party, whether by way of debt, equity or otherwise and there are no Convertible Debentures outstanding, then, the Total Commitment Amount was to be reduced automatically upon the closing of the financing by the lesser of: (i) the Total Commitment Amount; and (ii) the net proceeds of the financing. On February 6, 2007, the Company raised gross proceeds in the amount of $10,016,000 in a private placement of shares of its common stock and warrants. The Total Commitment Amount was therefore reduced to zero, thus effectively terminating Mr. Vamvakas’ standby commitment. No portion of the standby commitment was ever drawn down by the Company, and the Company paid Mr. Vamvakas a total of $29,808 in commitment fees in February 2007.

Interest expense for the years ended December 31, 2007 and 2006 consists primarily of the commitment fee due to Mr. Vamvakas on the undrawn portion of the Total Commitment Amount during the periods. There was no comparable expense during the year ended December 31, 2005.

Other Income (Expense)

Other income for the years ended December 31, 2007 and 2006 consists primarily of foreign exchange gain of $22,889 and $37,229, respectively, due to exchange rate fluctuations on the Company's foreign currency transactions. This gain was offset by miscellaneous tax expense of $4,879 and $6,120 during the years ended December 31, 2007 and 2006, respectively. Other expense was $57,025 for the year ended December 31, 2005 and consists of a provision for subscription receivable of $34,927 and miscellaneous tax expense of $23,021.

Minority Interest

As a result of the restatement of the financial statements as discussed earlier, the amount of losses allocated to minority interest decreased by $870,665 in the year ending December 31, 2007 and increased by $3,555 in the year ending December 31, 2006.

The decrease in the year ending December 31, 2007 was primarily related the following

reflecting the minority interest share of tax losses benefited in the year of $816,444;

a decrease in the minority interest applicable percentage from what was previously applied (49.9%) to 42.38% of $342,871; and

a decrease related to the minority interest share of the excess of the alpha milestone payment of $2,000,000 over the estimated fair value on the date of our acquisition of OcuSense $130,291.

These decreases were partially offset by the following increases:

an increase in the net amortization of intangibles and deferred tax liabilities arising from fair valuing minority interest on the date of acquisition of $327,872, and

the minority interest share of losses previously not reported for reason of the minority interest share of losses having exceeded the value of minority interest reported on acquisition of $91,069.

The minority interest share of losses in the year ending December 31, 2007 increased by $1,151,542 from the share of losses reported in the year ending December 31, 2006 which is consistent with the fact that the 2006 results reflect only one month’s share of losses subsequent to the November 30, 2006 our acquisition of OcuSense.

Recovery of Income Taxes

For the years ended December 31,

(in thousands)

	2007		Change			2006		Change			2005

Recovery of income taxes for continuing operations	$	5,566		91	%	$	2,916		353	%		643

As a result of the restatement of the financial statements as discussed earlier, the amount of taxes recovered decreased by $89,326 in the year ending December 31, 2007 from what was originally reported to $5,565,542 and increased by $27,300 from what was originally reported to $2,915,790 in the year ending December 31, 2006.

The decrease in the year ending December 31, 2007 was primarily related the following:

a reversal of tax losses benefited in the year of $381,597, ($0 in 2006), and

a decrease related to the reversal of the amortization of deferred taxes related to the initial accounting of the alpha payment of $2,000,000 of $35,327 ($0 in 2006)

These decreases were partially offset by the following increases:

a decrease in the minority interest applicable percentage from what was previously applied (49.9%) to 42.38% of $327,599, ($27,300 in 2006) .

As a result of the restatement of the financial statements as discussed earlier, the amount reported as the recovery of income taxes decreased by $89,326 in the year ending December 31, 2007 from what was originally reported to $5,565,542 and increased by $27,300 in the year ending December 31, 2006 from what was originally reported to $2,915,790. The decrease in the year ending December 31, 2007 related primarily to the reversal of tax benefits previously reported of $381,597 and the reversal of $35,327 of the amortization of the deferred taxes originally reported resulting from the payment by the Company of the alpha milestone to OcuSense of $2,000,000 offset by increased amortization of deferred taxes arising from fair valuing minority interest on the date of the acquisition of OcuSense by us of $327,599.

Recovery of income taxes increased by $2,649,752 during the year ended December 31, 2007, as compared with the prior period in 2006. The increase is due to the elimination of the deferred tax liability of $7,995,790 associated with our distribution intangible which was fully impaired as at December 31, 2007. In addition, we recorded a deferred tax recovery in the amount of $1,863,391 associated with the recognition of the deferred tax asset from the availability of net operating losses in the United States of OcuSense during the 2007 fiscal year which may be utilized to reduce taxes in future years. These increases in recovery of income taxes were offset in part by a valuation allowance increase of $4,809,456 associated with our Retina division. A deferred tax asset was recognized in prior years as the asset was believed to be more likely than not to be realized based on existing taxable temporary differences.

Recovery of income taxes increased by $2,273,261 during the year ended December 31, 2006, as compared with the prior period in 2005 due primarily to the recognition of deferred tax asset from the availability of fiscal 2006 net operating losses in the United States which may be utilized to reduce taxes in future years. There was no comparable benefit recorded during the year ended December 31, 2005.

To date, we have recognized income tax benefits in the aggregate amount of $2.2 million associated with the recognition of the deferred tax asset from the availability of net operating losses in the United States which may be utilized to reduce taxes in future years. The benefits associated with the balance of the net operating losses are subject to a full valuation allowance since it is not more likely than not that these losses can be utilized in future years.

Recovery of income taxes for the years ended December 31, 2007 and 2006 also includes the amortization of the deferred tax liability of $515,815 and $42,985, respectively, which was recorded based on the difference between the fair value of intangible asset acquired upon the acquisition of OcuSense on November 30, 2006 and its tax base. The increase in the amount recorded during the year ended December 31, 2007 as compared with the corresponding period in fiscal 2006 arises because the acquisition of 57.62% of the capital stock of OcuSense, 50.1% on a fully diluted basis, was completed by us on November 30, 2006. Therefore, recovery of income taxes for the year ended December 31, 2006 only included one month’s amortization of the deferred tax liability recorded upon the acquisition of OcuSense. The deferred tax liability totaling $5,158,155 is being amortized over a period of approximately 10 years, the estimated useful life of the intangible asset. There was no comparable income tax benefit recorded during the year ended December 31, 2005

Discontinued Operations

On December 19, 2007, the Company sold to Solx Acquisition, and Solx Acquisition purchased from us, all of the issued and outstanding shares of the capital stock of SOLX, which had been our glaucoma subsidiary prior to the completion of this transaction. The consideration for the purchase and sale of all of the issued and outstanding shares of the capital stock of SOLX consisted of: (i) on the closing date of the sale, the assumption by Solx Acquisition of all of the Company's liabilities related to SOLX’s business, incurred on or after December 1, 2007, and our obligation to make a $5,000,000 payment to the former stockholders of SOLX due on September 1, 2008 in satisfaction of the outstanding balance of the purchase price of SOLX; (ii) on or prior to February 15, 2008, the payment by Solx Acquisition of all of the expenses that the Company have paid to the closing date, as they related to SOLX’s business during the period commencing on December 1, 2007; (iii) during the period commencing on the closing date and ending on the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 3% of the worldwide net sales of the SOLX 790 Laser and the SOLX Gold Shunt, including next-generation or future models or versions of these products; and (iv) following the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 5% of the worldwide net sales of these products. In order to secure the obligation of Solx Acquisition to make these royalty payments, SOLX granted to the Company a subordinated security interest in certain of its intellectual property. No value was assigned to the royalty payments as the determination of worldwide net sales of SOLX’s products is subject to significant uncertainty.

Revenues

Revenue consists of revenue generated from the sale of components of the SOLX Glaucoma System.

We completed the acquisition of SOLX on September 1, 2006. On December 20, 2007, we announced the sale of SOLX to Solx Acquisition. The results of SOLX’s operations have therefore been included in our consolidated financial statements from September 1, 2006 to December 19, 2007, the closing date of the sale of SOLX.

Revenue therefore includes the sale of SOLX Gold Shunts from September 1, 2006 to December 19, 2007. There was no comparative revenue during the year ended December 31, 2005.

Cost of Sales

Cost of sales includes costs of goods sold and royalty costs. Our cost of goods sold consists primarily of costs for the manufacture of the SOLX Glaucoma System, including the costs we incur for the purchase of component parts from our suppliers, applicable freight and shipping costs, fees related to warehousing, logistics inventory management and recurring regulatory costs associated with conducting business and ISO certification.

Cost of sales includes the cost of the components of the SOLX Glaucoma System sold during the years ended December 31, 2007 and 2006.

Gross Margin

Gross margin on the sale of SOLX Gold Shunts was 41% during each of the years ended December 31, 2007 and 2006.

General and Administrative Expenses

General and administrative expenses increased by $2,252,407 during the year ended December 31, 2007, as compared with the corresponding period of fiscal 2006, due to an increase of $1,738,334 in the amortization of the intangible assets acquired during fiscal 2006 upon the acquisition of SOLX on September 1, 2006. SOLX employee and related travel costs and administrative expenses also increased by $311,886 and $183,575, respectively, during the year ended December 31, 2007 as compared with the corresponding period in fiscal 2006. We acquired SOLX on September 1, 2006. Therefore, general and administrative expenses for the year ended December 31, 2006 include SOLX’s cost for four months to December 2006.

Clinical and Regulatory Expenses

SOLX’s clinical and regulatory expenses increased by $2,074,062 during the year ended December 31, 2007 as compared with the comparative period in 2006. We acquired SOLX on September 1, 2006. Therefore, clinical and regulatory expenses for the year ended December 31, 2006 include SOLX’s cost for the four months ended December 31 2006.

Sales and Marketing Expenses

Sales and marketing expenses increased by $488,091 due to the increase in SOLX’s sales and marketing expenses of $315,581 and increased employee and related travel costs and administrative expenses of $107,935 and $28,686, respectively.

Impairment of Goodwill

On September 1, 2006, the Company acquired SOLX by way of a merger for a total purchase price of $29,068,443. Of this amount, $14,446,977 was allocated to goodwill. On December 19, 2007, the Company sold all of the issued and outstanding shares of the capital stock of SOLX to Solx Acquisition. The sale transaction established fair values for the Company's recorded goodwill and certain of the Company's intangible assets. Accordingly, the Company performed an impairment test of its recorded goodwill to re-assess whether its recorded goodwill was impaired as at December 1, 2007. Based on the goodwill impairment analysis performed, the Company concluded that a goodwill impairment charge of $14,446,977 should be recorded during the year ended December 31, 2007 to write down the value of its recorded goodwill to its fair value of nil as at December 31, 2007.

Impairment of Intangible Assets

The SOLX sale transaction established fair values for the Company's recorded goodwill and the Company's shunt and laser technology and regulatory and other intangible assets acquired upon the acquisition of SOLX on September 1, 2006. Accordingly, management was required to re-assess whether the carrying value of the Company's shunt and laser technology and regulatory and other intangible assets was recoverable as of December 1, 2007. Based on management’s estimates of undiscounted cash flows associated with these intangible assets, the Company concluded that the carrying value of these intangible assets was not recoverable as of December 1, 2007. Accordingly, the Company recorded an impairment charge of $22,286,383 during the year ended December 31, 2007 to record the shunt and laser technology and regulatory and other intangible assets at their fair value as of December 31, 2007.

Accretion Expense

In connection with the acquisition of SOLX on September 1, 2006, we remained indebted to the former stockholders of SOLX in an aggregate amount of up to $13,000,000 for the outstanding portion of the purchase price of SOLX. $5,000,000 of this amount was payable in cash on the second anniversary of the September 1, 2006 closing. The $5,000,000 was recorded as a long-term liability at its present value, discounted at the incremental borrowing rate of the Company as at August 1, 2006. The difference between the discounted value and the $5,000,000 payable was being amortized using the effective yield method over the two-year period with the monthly expense being charged as an interest expense in the Company's consolidated statement of operations. Accretion expense for the year ended December 31, 2007 and 2006 consists primarily of the accretion expense for the years ended December 2007 and 2006.

	2007		Change			2006

Recovery of income taxes	$	9,350		691	%	$	1,182

Recovery of Income Taxes

Recovery of income taxes increased by $8,167,877 during the year ended December 31, 2007, as compared with the prior period in 2006. The increase is primarily due to the elimination of the deferred tax liability of $11,861,145 associated with the intangible assets acquired upon the acquisition of SOLX on September 1, 2006 as these intangible assets were impaired as at December 31, 2007. This increase in recovery of income taxes were offset in part by a valuation allowance increase of $2,511,263 associated with the Company's Glaucoma division. A deferred tax asset was recognized in prior years as the asset was believed to be more likely than not to be realized based on existing taxable temporary differences.

The recovery of income taxes was $1,182,005 during the year ended December 31, 2006 primarily due to the recognition of the deferred tax asset of $773,395 from the availability of fiscal 2006 net operating losses in the United States which may be utilized to reduce taxes in future years. Also impacting the recovery of income taxes was the amortization of the deferred tax liability of $409,055 which was recorded based on the difference between the fair value of intangible assets acquired and its tax bases.

In December 2004, we raised $67,200,000 of gross cash proceeds (less issuance costs of $7,858,789) in an initial public offering of shares of its common stock. Immediately prior to the offering, the primary source of the Company's liquidity was cash raised through the issuance of debentures.

On February 6, 2007, the Company raised gross proceeds in the amount of $10,016,000 (less issuance costs of approximately $750,000) in a private placement of shares of its common stock and warrants.

On February 19, 2008, the Company announced that we secured a bridge loan in an aggregate principal amount of $3,000,000 (less transaction costs of approximately $200,000) from a number of private parties. The loan bears interest at a rate of 12% per annum and has a 180-day term, which may be extended to 270 days under certain circumstances. The repayment of the loan is secured by a pledge by the Company of its shares of the capital stock of OcuSense.

To date, cash has been primarily utilized to finance increased infrastructure costs, to accumulate inventory and to fund costs of the MIRA-1, LEARN and RHEO-AMD trials and other clinical trials and to acquire SOLX and OcuSense in line with our diversification strategy. With the suspension of the Company's RHEO™ System clinical trial development program, and the consequent winding-down of the RHEO-AMD study, and the Company's disposition of SOLX, we expect that, in the future, we will use our cash resources to complete the product development of OcuSense’s TearLab™ test for DED and conduct the clinical trials that will be required for the TearLab™ test for DED. In addition, we remain indebted to OcuSense in an aggregate amount of up to $2,000,000 for the outstanding portion of the purchase price of the capital stock of OcuSense that we acquired on November 30, 2006. We currently expect this amount to become due and payable during the first half of 2008. Furthermore, we are legally committed to make an additional equity investment of $3,000,000 upon receipt, if any, from the FDA of a 510(k) clearance for the TearLab™ test for DED and another additional equity investment of $3,000,000 upon receipt, if any, from the FDA of a CLIA waiver for the TearLab™ test for DED.

As at December 31, 2007, we had investments in the aggregate principal amount of $1,900,000 which consist of investments in four separate asset-backed auction rate securities yielding an average return of 5.865% per annum. Contractual maturities for these auction rate securities range from 33 to 39 years, with an average interest reset date of approximately 46 days. Historically, the carrying value of auction rate securities approximated their fair value due to the frequent resetting of interest rates. However, as a result of market conditions associated with the liquidity issues experienced in the global credit and capital markets, all of these investments have recently failed to settle on their respective settlement dates and have been reset to be settled at a future date with an average maturity of 46 days.

Due to the current lack of liquidity for asset-backed securities of this type, we concluded that the carrying value of these investments was higher than its fair value as of December 31, 2007. Accordingly, these auction rate securities have been recorded at their estimated fair value of $863,750, which represents a decline of $1,036,250 in the carrying value of these auction rate securities. We estimated the fair value of these auction rate securities based on the following: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions; (iii) consideration of the probabilities of default, auction failure, or repurchase at par for each period; and (iv) estimates of the recovery rates in the event of default for each security. This estimated fair value could change significantly based on future market conditions.

We determined the reduction in the value of these auction rate securities to be an other-than-temporary reduction in value. Accordingly, the impairment associated with these auction rate securities of $1,036,250 has been included as an impairment of investments in our consolidated statement of operations for the year ended December 31, 2007. Our conclusion for the other-than-temporary impairment is based on the Company's current liquidity position. Although we continue to receive payment of interest earned on these securities, we do not know at the present time when we will be able to convert these investments into cash. Accordingly, management has classified these investments as a non-current asset on its consolidated balance sheet as of December 31, 2007. Management will continue to closely monitor these investments for future indications of further impairment. If the current market conditions deteriorate further, or the anticipated recovery in market values does not occur, we may be required to record additional impairment charges in fiscal 2008.

The illiquidity of these investments may have an adverse impact on the length of time during which we currently expect to be able to sustain our operations in the absence of an additional capital raise by the Company as we do not have the ability to hold these auction rate securities until the market recovers nor can we hold these securities until their contractual maturity dates.

Cash Used in Operating Activities

Net cash used to fund our operating activities during the year ended December 31, 2007 was $17,217,438. Net loss during the year was $69,829,983. The non-cash charges which comprise a portion of the net loss during that period consisted primarily of the intangible assets and goodwill impairment of $57,656,388 and the amortization of intangible assets, fixed assets, patents and trademarks and accretion expense of $6,349,148 netted by applicable deferred income taxes of $14,915,425 and minority interest of $1,312,178. Additional non-cash charges consist of $480,971 in stock-based compensation charges and impairment of investments of $1,036,250 netted by the change in the fair value of warrant obligation of $1,882,497.

The net change in non-cash working capital balances related to operations for the years ended December 31, 2007, 2006 and 2005 consists of the following:

·	Amounts receivable increased due primarily to the expected repayment by Solx Acquisition, on or prior to February 15, 2008, in accordance with the stock purchase agreement between the Company and Solx Acquisition, of all the expenses relating to the SOLX business that we had paid.

·	Decrease in inventory balance reflects the write-down of inventory and the provision for obsolescence for inventory we are not expected to be able to sell prior to their expiration dates.

·	Decrease in prepaid expenses is primarily due to the expensing of advance payments made to various organizations involved in the RHEO-AMD trial due to our suspension of the trial, offset in part by prepaid insurance premiums.

·	Accounts payable and accrued liabilities increased and reflect amounts owed for costs associated with the Company's activities.

·	The decrease in amounts due to stockholders is due to payments made to TLC Vision during the year ended December 31, 2007 for its payment of benefits of certain of our employees and for computer and administrative support.

Cash Provided by Investing Activities

Net cash provided by investing activities for the year ended December 31, 2007 is $4,510,838 and consists of the net sale of short-term investments of $7,885,000 offset in part by the payment of $3,000,000 to the former stockholders of SOLX in connection with the payment of the purchase price, cash in the amount of $267,934 used to acquire fixed assets and cash in the amount of $106,228 used to protect and maintain patents and trademarks.

Net cash provided by investing activities for the year ended December 31, 2006 was $10,418,156 and resulted from cash generated from the sale of short-term investments of $21,841,860. Cash used in investing activities during the period consists of $255,886 used to acquire fixed assets and $105,217 used to protect and maintain patents and trademarks. Additional cash used in investing activities includes cash of $7,906,968 paid by the Company, including costs of acquisition, to acquire SOLX net of cash acquired from SOLX of $34,719. In addition, the Company advanced a total of $2,434,537 to SOLX to support its operations prior to the acquisition. The Company also invested $2,076,312 to acquire 50.1% of the capital stock of OcuSense, on a fully diluted basis, 57.62% on an issued and outstanding basis, including acquisition costs of $76,312. Cash acquired upon the acquisition of OcuSense was $1,320,497. The $2,076,312 invested by us in OcuSense has been utilized to fund the operations of OcuSense.

Cash Provided by Financing Activities

Net cash provided by financing activities for the year ended December 31, 2007 was $9,201,735 and is made up of gross proceeds in the amount of $10,016,000 raised in the February 2007 private placement of the Shares and the Warrants, less issuance costs of $871,215 which includes the fair value of the Cowen Warrant of $97,222 issued in part payment of the placement fee owed to Cowen and Company, LLC. Cash provided by financing activities also includes cash received in the amount of $2,228 from the exercise of options to purchase shares of common stock of the Company, offset by additional share issuance costs of $42,500 in respect of the shares issued to the former stockholders of SOLX in part payment of the purchase price of SOLX.

Net cash provided by financing activities for the year ended December 31, 2006 was $270,935 and reflects cash received from the exercise of options to purchase shares of common stock of the Company.

Borrowings

On November 30, 2006, we announced that Elias Vamvakas, our Chairman and Chief Executive Officer, had agreed to provide us with a standby commitment to purchase Convertible Debentures of the Company for a Total Commitment Amount of $8,000,000. Pursuant to the Summary of Terms and Conditions, during the 12-month commitment term commencing on November 30, 2006, upon no less than 45 days’ written notice by the Company to Mr. Vamvakas, Mr. Vamvakas was obligated to purchase Convertible Debentures in the aggregate principal amount specified in such written notice. A commitment fee of 200 basis points was payable by the Company on the undrawn portion of the total $8,000,000 commitment amount. Any Convertible Debentures purchased by Mr. Vamvakas would have carried an interest rate of 10% per annum and would have been convertible, at Mr. Vamvakas’ option, into shares of the Company's common stock at a conversion price of $2.70 per share. The Summary of Terms and Conditions of the standby commitment further provided that if the Company closed a financing with a third party, whether by way of debt, equity or otherwise and there are no Convertible Debentures outstanding, then, the Total Commitment Amount was to be reduced automatically upon the closing of the financing by the lesser of: (i) the Total Commitment Amount; and (ii) the net proceeds of the financing. On February 6, 2007, the Company raised gross proceeds in the amount of $10,016,000 in a private placement of shares of its common stock and warrants. The Total Commitment Amount was therefore reduced to zero, thus effectively terminating Mr. Vamvakas’ standby commitment. No portion of the standby commitment was ever drawn down by the Company, and the Company paid Mr. Vamvakas a total of $29,808 in commitment fees in February 2007.

Contractual Obligations and Contingencies

The following table summarizes our contractual commitments as of December 31, 2007 and the effect those commitments are expected to have on liquidity and cash flow in future periods.

On November 30, 2006, pursuant to the Series A Preferred Stock Purchase Agreement between us and OcuSense, we purchased 1,744,223 shares of OcuSense’s Series A Preferred Stock representing 50.1% of OcuSense’s capital stock on a fully diluted basis, 57.62% on an issued and outstanding basis, for an aggregate purchase price of up to $8,000,000. On the closing of the purchase which took place on November 30, 2006, we paid $2,000,000 of the purchase price. We paid another $2,000,000 installment of the purchase price on January 3, 2007. We agreed to make additional payments totaling $4,000,000 upon the attainment of two pre-defined milestones by OcuSense prior to May 1, 2009. In June 2007, we paid OcuSense a total of $2,000,000 upon the attainment of the first of the two pre-defined milestones. We will pay the last $2,000,000 installment of the purchase price upon the attainment by OcuSense of the second of such milestones, provided that the milestone is achieved prior to May 1, 2009. The Series A Preferred Stock Purchase Agreement also makes provision for an ability on our part to increase our ownership interest in OcuSense for nominal consideration if OcuSense fails to meet certain milestones by specified dates. In addition, pursuant to the Series A Preferred Stock Purchase Agreement, we have agreed to purchase $3,000,000 of shares of OcuSense’s Series B Preferred Stock, which shall constitute 10% of OcuSense’s capital stock on a fully diluted basis at the time of purchase, upon OcuSense’s receipt from the FDA of 510(k) clearance for the DED Test and to purchase another $3,000,000 of shares of OcuSense’s Series B Preferred Stock, which shall constitute an additional 10% of OcuSense’s capital stock on a fully diluted basis at the time of purchase, upon OcuSense’s receipt from the FDA of CLIA waiver for the DED Test.

Pursuant to the terms of our distribution agreement with MeSys GmbH, or MeSys, dated January 1, 2002, we undertook a minimum purchase commitment of 25 OctoNova pumps per year beginning after FDA approval of the RHEO™ System, representing an annual commitment after FDA approval of €405,000, or approximately $534,900. The marketing and distributorship agreement with Diamed provides for a minimum purchase of 1,000 OctoNova pumps during the period from the date of the agreement until the end of the five-year period following receipt of FDA approval, representing an aggregate commitment of €16,219,000, or approximately $23,871,935, based on exchange rates as of December 31, 2007.

Off-Balance-Sheet Arrangements

As of December 31, 2007, we did not have any significant off-balance-sheet arrangements as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.

Financial Condition

Management believes that the existing cash and cash equivalents and short-term investments, together with the net proceeds of the bridge loan, will be sufficient to fund the Company's anticipated level of operations and other demands and commitments until approximately the end of April 2008 (assuming that the outstanding obligation of OccuLogix to pay $2,000,000 to OcuSense becomes due and payable prior to the end of April 2008).

As at December 31, 2007, we had investments in the aggregate principal amount of $1,900,000 which consist of investments in four separate asset-backed auction rate securities yielding an average return of 5.865% per annum. However, as a result of market conditions, all of these investments have recently failed to settle on their respective settlement dates and have been reset to be settled at a future date with an average maturity of 46 days. Based on discussions with the Company's advisors and the current lack of liquidity for asset-backed securities of this type, we concluded that the carrying value of these investments was higher than its fair value as of December 31, 2007. Accordingly, these auction rate securities have been recorded at their estimated fair value of $863,750. We consider this to be an other-than-temporary reduction in the value, accordingly, the impairment associated with these auction rate securities of $1,036,250 has been included as an impairment of investments in our consolidated statement of operations for the year ended December 31, 2007. Although we continue to receive payment of interest earned on these securities, we do not know at the present time when it will be able to convert these investments into cash. Accordingly, management has classified these investments as a non-current asset on its consolidated balance sheet as of December 31, 2007. Management will continue to closely monitor these investments for future indications of further impairment. The illiquidity of these investments may have an adverse impact on the length of time during which we currently expect to be able to sustain its operations in the absence of an additional capital raise by the Company.

Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties. Actual results could vary as a result of a number of factors. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. Our future funding requirements will depend on many factors, including but not limited to:

the cost and results of development of OcuSense’s TearLab™ test for DED;

the cost and results, and the rate of progress, of the clinical trials of the TearLab™ test for DED that will be required to support OcuSense’s application to obtain 510(k) clearance and a CLIA waiver from the FDA to market and sell the TearLab™ test for DED in the United States;

OcuSense’s ability to obtain 510(k) approval and a CLIA waiver from the FDA for the TearLab™ test for DED and the timing of such approval, if any;

whether government and third-party payors agree to reimburse treatments using the TearLab™ test for DED;

the costs and timing of building the infrastructure to market and sell the TearLab™ test for DED;

the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights; and

the effect of competing technological and market developments.

We cannot begin commercialization of the TearLab™ test for DED in the United States until we receive FDA approval. At this time, we do not know when we can expect to begin to generate revenues from the TearLab™ test for DED in the United States.

We will need additional capital in the future, and our prospects for obtaining it are uncertain. On October 9, 2007, we announced that the Board had authorized management and the Company's advisors to explore the full range of strategic alternatives available to enhance shareholder value, including, but not limited to, the raising of capital through the sale of securities, one or more strategic alliances and the combination, sale or merger of all or part of the Company. For some time prior to the October 9, 2007 announcement, the Company had been seeking to raise additional capital, with the objective of securing funding sufficient to sustain its operations as it had been clear that, unless we were able to raise additional capital, the Company would not have had sufficient cash to support its operations beyond early 2008. Although the Company secured a bridge loan in an aggregate principal amount of $3,000,000 from a number of private parties on February 19, 2008, management believes that these net proceeds, together with the Company's existing cash and cash-equivalents, will be sufficient to cover its operating activities and other demands only until approximately the end of April 2008 (assuming that the outstanding obligation of OccuLogix to pay $2,000,000 to OcuSense becomes due and payable prior to the end of April 2008). Additional capital may not be available on terms favorable to us, or at all. In addition, future financings could result in significant dilution of existing stockholders. However, unless we succeed in raising additional capital, we will be unable to continue our operations. See “Risk Factors—Risks Relating to Our Business—Our financial condition and history of losses have caused our auditors to express doubt as to whether we will be able to continue as a going concern.”

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our audited consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amount of assets, liabilities, sales and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to our intangible assets, uncollectible receivables, inventories, goodwill and stock-based compensation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Because this can vary in each situation, actual results may differ from these estimates under different assumptions or conditions.

We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our audited consolidated financial statements.

Revenue Recognition

The Company recognized revenue from the sale of the RHEO™ System, prior to the Company's announcement of the indefinite suspension of its RHEO™ System clinical development program, which is comprised of OctoNova pumps and the related disposable treatment sets and, prior to the Company's disposition of SOLX on December 19, 2007, from the sale of the components of the SOLX Glaucoma System which includes the SOLX 790 Titanium Sapphire Laser (“SOLX 790 Laser”) and the SOLX Gold Shunt. The Company received a signed binding purchase order from its customers. The pricing was a negotiated amount between the Company and its customers. The Company sold the components of the SOLX Glaucoma System directly to physicians and also through distributors. Revenue has been reported net of distributors’ commissions.

The Company had the obligation to train its customers and to calibrate the OctoNova pumps delivered to them. Only upon the completion of these services did the Company recognize revenue for the pumps. The Company were also responsible for providing a one-year warranty on the OctoNova pumps, and the estimated cost of providing this service was accrued at the time revenue is recognized. The treatment sets and the components of the SOLX Glaucoma System did not require any additional servicing and revenue was recognized upon passage of title. However, the Company's revenue recognition policy requires an assessment as to whether collectibility is reasonably assured, which requires the Company to evaluate the creditworthiness of its customers. The result of the assessment could materially impact the timing of revenue recognition.

Bad Debt Reserves

The Company evaluates the collectibility of its accounts receivable based on a combination of factors. In cases where management is aware of circumstances that may impair a specific customer’s ability to meet its financial obligations to the Company, a specific allowance against amounts due to the Company is recorded, which reduces the net recognized receivable to the amount management reasonably believes will be collected. For all other customers, the Company recognizes allowances for doubtful accounts based on the length of time the receivables are past due, the current business environment and historical experience. As at December 31, 2007 and 2006, the Company had bad debt reserves of $172,992 and nil, respectively. The Company expensed amounts related to bad debt reserves of nil, nil and $518,852 during the years ended December 31, 2007, 2006 and 2005, respectively, and set up a provision for $172,992, nil and $530,445 representing invoices for products shipped, plus related taxes, to a customer during the years ended December 31, 2007, 2006 and 2005, respectively, for which revenue was not recognized due to the likelihood that the customer would not be able to pay for the amounts invoiced.

Inventory Valuation

Inventory is recorded at the lower of cost and net realizable value and consists of finished goods. Cost is accounted for on a first-in, first-out basis. Deferred cost of sales (included in finished goods) consists of products shipped but not recognized as revenue because they did not meet the revenue recognition criteria.

The Company evaluates its ending inventory for estimated excess quantities and obsolescence, based on expected future sales levels and projections of future demand, with the excess inventory provided for. In addition, the Company assesses the impact of changing technology and market conditions. In addition, the Company assesses whether recent transactions provide indicators as to whether the net realizable value of its inventory is below its recorded cost. In April 2006, the Company sold a number of treatment sets to Veris Health Sciences Inc. (“Veris”) at a price lower than the Company's cost. Accordingly, the Company wrote down the value of its treatment sets to reflect this current net realizable value during the year ended December 31, 2006. In light of the Company's current financial position, on November 1, 2007, the Company announced an indefinite suspension of the RHEO™ System clinical development program for Dry AMD. That decision was made following a comprehensive review of the respective costs and development timelines associated with the products in the Company's portfolio and, in particular, the fact that, if the Company is unable to raise additional capital, it will not have sufficient cash to support its operations beyond early 2008. Accordingly, the Company has written down the value of its treatment sets and OctoNova pumps, the components of the RHEO™ System, to nil as of December 31, 2007 since we are not expected to be able to sell or utilize these treatment sets and OctoNova pumps prior to their expiration dates, in the case of the treatment sets, or before the technologies become outdated.

As at December 31, 2007 and 2006, the Company had inventory reserves of $7,295,545 and $5,101,394, respectively. During the years ended December 31, 2007, 2006 and 2005, the Company recognized a provision related to inventory of $2,790,209, $3,304,124 and $1,990,830, respectively, based on the above analysis.

Impairment of long-lived assets

We review our fixed assets and intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. When such an event occurs, management estimates the future undiscounted cash flows expected to result from the use of the asset and its eventual disposition. In the event the undiscounted cash flows are less than the carrying amount of the asset, a further analysis is required to estimate the fair value of the asset using the discounted cash flow method and then an impairment loss equal to the excess of the carrying amount over the fair value is charged to operations.

Our intangible assets consist of the value of the exclusive distribution agreements we have with Asahi Medical and MeSys and other acquisition-related intangibles arising from our acquisition of SOLX and OcuSense during fiscal 2006 prior to the sale of SOLX on December 19, 2007. The distribution agreements and other acquisition-related intangible assets are amortized using the straight-line method over an estimated useful life of 15 and 10 years, respectively.

On November 1, 2007, we announced an indefinite suspension of the RHEO™ System clinical development program for Dry AMD and are in the process of winding down the RHEO-AMD study as there is no reasonable prospect that the RHEO™ System clinical development program will be relaunched in the foreseeable future. In accordance with SFAS No. 144, we concluded that its indefinite suspension of the RHEO™ System clinical development program for Dry AMD was a significant event which may affect the carrying value of the Company's distribution agreements. Accordingly, management was required to re-assess whether the carrying value of our distribution agreements was recoverable as of December 31, 2007. Based on management’s estimates of undiscounted cash flows associated with the distribution agreements, we concluded that the carrying value of the distribution agreements was not recoverable as of December 31, 2007. Accordingly, we recorded an impairment charge of $20,923,028 during the year ended December 31, 2007 to record the distribution agreements at their fair value as of December 31, 2007.

On December 19, 2007, we sold to Solx Acquisition, all of the issued and outstanding shares of the capital stock of SOLX. The sale transaction established fair values for the Company's recorded goodwill and the Company's shunt and laser technology and regulatory and other intangible assets acquired upon the acquisition of SOLX on September 1, 2006. Accordingly, management was required to re-assess whether the carrying value of the Company's shunt and laser technology and regulatory and other intangible assets was recoverable as of December 1, 2007. Based on management’s estimates of undiscounted cash flows associated with these intangible assets, we concluded that the carrying value of these intangible assets was not recoverable as of December 1, 2007. Accordingly, we recorded an impairment charge of $22,286,383 during the year ended December 31, 2007 to record the shunt and laser technology and regulatory and other intangible assets at their fair value as of December 31, 2007.

The Company determined that, as at December 31, 2007, there have been no significant events which may affect the carrying value of its TearLab™ technology. However, the Company's prior history of losses and losses incurred during the current fiscal year reflects a potential indication of impairment, thus requiring management to assess whether the OcuSense’s TearLab™ technology was impaired as of December 31, 2007. Based on management’s estimates of forecasted undiscounted cash flows as of December 31, 2007, the Company concluded that there is no indication of an impairment of the OcuSense’s TearLab™ technology. Therefore, no impairment charge was recorded during the year ended December 31, 2007.

Impairment of Goodwill

Effective January 1, 2002, goodwill is no longer amortized and is subject to an annual impairment test. Goodwill impairment is evaluated between annual tests upon the occurrence of certain events or circumstances. Goodwill impairment is assessed based on a comparison of the fair value of the reporting unit to the underlying carrying value of the reporting unit’s net assets, including goodwill. When the carrying amount of the reporting unit exceeds its fair value, the fair value of the reporting unit’s goodwill is compared with its carrying amount to measure the amount of impairment loss, if any.

Prior to the acquisition of SOLX and OcuSense during the second half of fiscal 2006, the Company was a single reporting unit. Therefore, management determined the fair value of the Company's goodwill using the Company's market capitalization as opposed to the fair value of its assets and liabilities. As a result of the announcement on February 3, 2006, the per share price of our common stock as traded on NASDAQ decreased from $12.75 on February 2, 2006 to close at $4.10 on February 3, 2006. The 10-day average price of the stock immediately following the announcement was $3.65 and reflected a decrease in our market capitalization from $536.6 million on February 2, 2006 to $153.6 million based on the 10-day average share price subsequent to the announcement. On June 12, 2006, we announced that the FDA will require us to perform an additional study of the RHEO™ System. In addition, on June 30, 2006, we announced that we had terminated negotiations with Sowood in connection with a proposed private purchase of approximately $30,000,000 of zero-coupon convertible notes of the Company. The per share price of our common stock decreased subsequent to the June 12, 2006 announcement and again after the June 30, 2006 announcement. Based on the result of the preliminary analysis of the data from MIRA-1 and the events that occurred during the second quarter of fiscal 2006, we concluded that there were sufficient indicators of impairment leading to an analysis of our intangible assets and goodwill and resulting in our reporting an impairment charge to goodwill of $65,945,686 and $147,451,758 during the years ended December 31, 2006 and 2005, respectively.

Subsequent to the acquisition of SOLX and OcuSense, the Company determined the fair value of acquired goodwill based on a comparison of the fair value of the reporting unit to the underlying carrying value of the reporting unit’s net assets, including goodwill.

On December 19, 2007, the Company sold to Solx Acquisition, all of the issued and outstanding shares of the capital stock of SOLX, which had been the glaucoma subsidiary of the Company prior to the completion of this sale. The sale transaction established fair values for the Company's recorded goodwill and certain of the Company's intangible assets. Accordingly, the Company performed an impairment test of its recorded goodwill to re-assess whether its recorded goodwill was impaired as at December 1, 2007. Based on the goodwill impairment analysis performed, the Company concluded that a goodwill impairment charge of $14,446,977 should be recorded during the year ended December 31, 2007 to write down the value of its recorded goodwill to its fair value of nil as at December 31, 2007.

Stock-based Compensation

We account for stock-based compensation in accordance with the provisions of SFAS 123R. Under the fair value recognition provision of SFAS 123R, stock-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as an expense ratably over the requisite service period of the award. We have selected the Black-Scholes option-pricing model as our method of determining the fair value for all our awards and will recognize compensation cost on a straight-line basis over the awards’ vesting periods.

Impairment of Investments

As at December 31, 2007, we had investments in the aggregate principal amount of $1,900,000 which consist of investments in four separate asset-backed auction rate securities yielding an average return of 5.865% per annum. However, as a result of market conditions, all of these investments have recently failed to settle on their respective settlement dates and have been reset to be settled at a future date with an average maturity of 46 days. Due to the current lack of liquidity for asset-backed securities of this type, the Company concluded that the carrying value of these investments was higher than its fair value as of December 31, 2007. Accordingly, these auction rate securities have been recorded at their estimated fair value of $863,750. We consider this to be an other-than-temporary reduction in the value. Accordingly, the loss associated with these auction rate securities of $1,036,250 has been included as an impairment of investments in the Company's consolidated statement of operations for the year ended December 31, 2007. Although we continue to receive payment of interest earned on these securities, we do not know at the present time when we will be able to convert these investments into cash. Accordingly, management has classified these investments as a non-current asset on its consolidated balance sheet as of December 31, 2007. We will continue to closely monitor these investments for future indications of further impairment. The illiquidity of these investments may have an adverse impact on the length of time during which we currently expect to be able to sustain our operations in the absence of an additional capital raise by the Company.

Fair Value of Warrants

On February 6, 2007, pursuant to the Securities Purchase Agreement between the Company and certain institutional investors, the Company issued the Warrants to these investors. The Warrants are five-year warrants exercisable into an aggregate of 2,670,933 shares of the Company's common stock. On February 6, 2007, the Company also issued the Cowen Warrant to Cowen and Company, LLC in part payment of the placement fee payable to Cowen and Company, LLC for the services it had rendered as the placement agent in connection with the private placement of the Shares and the Warrants. The Cowen Warrant is a five-year warrant exercisable into an aggregate of 93,483 shares of the Company's common stock. The per share exercise price of the Warrants is $2.20, subject to adjustment, and the Warrants became exercisable on August 6, 2007. All of the terms and conditions of the Cowen Warrant (other than the number of shares of the Company's common stock into which it is exercisable) are identical to those of the Warrants. The Company account for the Warrants and the Cowen Warrant in accordance with the provisions of SFAS No. 133 along with related interpretation EITF 00-19. Based on the provisions of EITF 00-19, the Company determined that the Warrants and the Cowen Warrant do not meet the criteria for classification as equity. Accordingly, the Company has classified the Warrants and the Cowen Warrant as a current liability as at December 31, 2007. The estimated fair value was determined using the Black-Scholes option-pricing model. In addition, SFAS No. 133 requires the Company to record the outstanding derivatives at fair value at the end of each reporting period resulting in an adjustment to the recorded liability of the derivative, with any gain or loss recorded in earnings of the applicable reporting period. The Company therefore estimated the fair value of the Warrants and the Cowen Warrant as at December 31, 2007 and determined the aggregate fair value to be a nominal amount, a decrease of approximately $2,052,578 over the initial measurement of the aggregate fair value of the Warrants and the Cowen Warrant on the date of issuance.

Effective Corporate Tax Rate

Income Taxes

As of December 31, 2007, we had net operating loss carry forwards for federal income taxes of $75 million. Our utilization of the net operating loss and tax credit carry forwards may be subject to annual limitations pursuant to Section 382 of the Internal Revenue Code, and similar state provisions, as a result of changes in our ownership structure. The annual limitations may result in the expiration of net operating losses and credits prior to utilization.

At December 31, 2007, we had recorded a deferred tax liability due to the difference between the fair value of our intangible assets and their tax bases. We also recorded a deferred tax asset, netted off against the deferred tax liability, from the availability of 2007 net operating losses in the United States which may be utilized to reduce taxes in future years. In addition, we also had additional deferred tax asset representing the benefit of net operating loss carry forwards and certain stock issuance costs capitalized for tax purposes. We did not record a benefit for this deferred tax asset because realization of the benefit was uncertain, and, accordingly, a valuation allowance is provided to offset the deferred tax asset.

The Company and its subsidiaries have current and prior year losses available to reduce taxable income and taxes payable in future years which, if not utilized, will expire as follows:

Recent Accounting Pronouncements

The adoption of Staff Accounting Bulletin No. 110, “Share-based payments” during fiscal 2007 did not have a material impact on our results of operations and financial position.

In September 2006, FASB issued Statement No. 157, “Fair Value Measurements” (“SFAS No. 157”). SFAS No. 157 defines fair value, establishes a framework and gives guidance regarding the methods used for measuring fair value, and expands disclosures about fair value measurements. SFAS No. 157 is effective for financial statements issued for fiscal years beginning on or after November 15, 2007 and for interim periods within those fiscal years.

On February 12, 2008, FASB issued FASB Staff Position No. 157-2, “Effective Date of FASB Statement No 157” (FSP No. 157”). FSP No. 157-2 amends SFAS No. 157 to delay the effective date of SFAS No. 157 for non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually) for fiscal years beginning after November 15, 2008.

On February 14, 2008, FASB issued FSP No. 157-1, “Application of FASB Statement No. 157 to FASB Statement No. 13 and Other Accounting Pronouncements that Address Fair Value Measurements for Purposes of Lease Classification or Measurement under Statement 13” (“FSP No. 157-1”). FSP No. 157-1 amends SFAS No. 157 to exclude SFAS No. 13, “Accounting for Leases” (“SFAS No. 13”), and other accounting pronouncements that address fair value measurements for purposes of lease classification or measurement under SFAS No. 13.

We are currently evaluating the impact that the adoption of SFAS No. 157, FSP No. 157-2 and FSP No. 157-1 will have on our results of operations and financial position.

In February 2007, FASB issued Statement No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115” (“SFAS No. 159”). SFAS No. 159 expands the use of fair value accounting but does not affect existing standards which require assets or liabilities to be carried at fair value. Under SFAS No. 159, a company may elect to use fair value to measure accounts and loans receivable, available-for-sale and held-to-maturity securities, equity method investments, accounts payable, guarantees and issued debt. Other eligible items include firm commitments for financial instruments that otherwise would not be recognized at inception and non-cash warranty obligations where a warrantor is permitted to pay a third party to provide the warranty goods or services. If the use of fair value is elected, any upfront costs and fees related to the item must be recognized in earnings and cannot be deferred (e.g., debt issue costs). The fair value election is irrevocable and generally made on an instrument-by-instrument basis, even if a company has similar instruments that it elects not to measure based on fair value. At the adoption date, unrealized gains and losses on existing items for which fair value has been elected are reported as a cumulative adjustment to beginning retained earnings. Subsequent to the adoption of SFAS No. 159, changes in fair value are recognized in earnings. SFAS No. 159 is effective for fiscal years beginning on or after November 15, 2007 and is required to be adopted by the Company in the first quarter of fiscal 2008. The adoption of SFAS No. 159 will not have a material impact on our results of operations and financial position.

In June 2007, FASB’s Emerging Issues Task Force (“EITF”) issued EITF Issue No. 06-11, “Accounting for Income Tax Benefits of Dividends on Share-Based Payment Awards” (“EITF No. 06-11”). EITF No. 06-11 requires that the tax benefits related to dividend equivalents paid on restricted stock units, which are expected to vest, be recorded as an increase to additional paid-in capital. EITF No. 06-11 is effective prospectively to the income tax benefits on dividends declared in fiscal years beginning on or after December 15, 2007. We are currently evaluating the impact the adoption of EITF No. 06-11 will have on our results of operations and financial position.

In December 2007, FASB issued Statement No. 141R (revised 2007), “Business Combinations (a revision of Statement No. 141)” (“SFAS No. 141R”). SFAS No. 141R applies to all transactions or other events in which an entity obtains control of one or more businesses, including those business combinations achieved without the transfer of consideration. SFAS No. 141R retains the fundamental requirements in Statement No. 141 that the acquisition method of accounting be used for all business combinations. SFAS No. 141R expands the scope to include all business combinations and requires an acquirer to recognize the assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree at their fair values as of the acquisition date. In addition, SFAS No. 141R changes the way entities account for business combinations achieved in stages by requiring the identifiable assets and liabilities to be measured at their full fair values. Also, contractual contingencies and contingent consideration shall be measured at fair value at the acquisition date. SFAS No. 141R is effective on a prospective basis to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. We are currently evaluating the impact, if any, that the adoption of SFAS No. 141R will have on our results of operations and financial position.

In December 2007, FASB issued Statement No. 160, “Noncontrolling Interests in Consolidated Financial Statements - an amendment of ARB No. 51” (“SFAS No. 160”). SFAS No. 160 amends ARB No. 51 to establish accounting and reporting standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS No. 160 clarifies that a non-controlling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. Additionally, SFAS No. 160 requires that consolidated net income include the amounts attributable to both the parent and the non-controlling interest. SFAS No. 160 is effective for interim periods beginning on or after December 15, 2008. We are currently evaluating the impact, if any, that the adoption of SFAS No. 160 will have on our results of operations and financial position.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Quantitative and Qualitative Disclosure of Market Risk

Currency Fluctuations and Exchange Risk

All of our sales are in U.S. dollars or are linked to the U.S. dollar, while a portion of our expenses are in Canadian dollars and Euros. We cannot predict any future trends in the exchange rate of the Canadian dollar or Euro against the U.S. dollar. Any strengthening of the Canadian dollar or Euro in relation to the U.S. dollar would increase the U.S. dollar cost of our operations, and affect our U.S. dollar measured results of operations. We do not engage in any hedging or other transactions intended to manage these risks. In the future, we may undertake hedging or other similar transactions or invest in market risk sensitive instruments if we determine that is advisable to offset these risks.

Interest Rate Risk

The primary objective of our investment activity is to preserve principal while maximizing interest income we receive from our investments, without increasing risk. We believe this will minimize our market risk.

As at December 31, 2007, we had investments in the aggregate principal amount of $1,900,000 which consist of investments in four separate asset-backed auction rate securities yielding an average return of 5.865% per annum. However, as a result of market conditions, all of these investments have recently failed to settle on their respective settlement dates and have been reset to be settled at a future date with an average maturity of 46 days. Due to the current lack of liquidity for asset-backed securities of this type, the Company has concluded that the carrying value of these investments was higher than its fair value as of December 31, 2007. Accordingly, these auction rate securities have been recorded at their estimated fair value of $863,750. We consider this to be an other-than-temporary reduction in the value. Accordingly, the loss associated with these auction rate securities of $1,036,250 has been included as an impairment of investments in the Company's consolidated statement of operations for the year ended December 31, 2007. Although we continue to receive payment of interest earned on these securities, we do not know at the present time when we will be able to convert these investments into cash. Accordingly, management has classified these investments as a non-current asset on its consolidated balance sheet as of December 31, 2007. We will continue to closely monitor these investments for future indications of further impairment. The illiquidity of these investments may have an adverse impact on the length of time during which we currently expect to be able to sustain our operations in the absence of an additional capital raise by the Company.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.

Consolidated Financial Statements

OccuLogix, Inc.

December 31, 2007 and 2006

REPORT OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of OccuLogix, Inc.

We have audited the accompanying consolidated balance sheets of OccuLogix, Inc. (the “Company”) as of December 31, 2007 and 2006 and the related consolidated statements of operations, changes in stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2007. Our audits also included the financial statement schedule listed in the index at Item 15(a). These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2007 and 2006 and the consolidated result of its operations and its cash flows for each of the three years in the period ended December 31, 2007 in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

Our previous audit report dated March 14, 2008, has been withdrawn, and the consolidated balance sheets as at December 31, 2007 and 2006 and the related consolidated statements of operations, changes in stockholders’ equity and cash flows for the years then ended have been restated, as described in note 2(a) to the consolidated financial statements.

The accompanying consolidated financial statements have been prepared assuming that OccuLogix, Inc. will continue as a going concern. As more fully described in Note 1, the Company has incurred recurring operating losses and has a working capital deficiency. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters also are described in Note 1. The financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty.

As discussed in Note 3 to these consolidated financial statements, the Company changed its accounting policy in regards to the accounting for income taxes for the year ended December 31, 2007. Additionally, as discussed in Note 17(e), the Company changed its accounting policy in regards to the accounting for stock-based compensation during the year ended December 31, 2006.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of OccuLogix, Inc.’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 14, 2008 (except for the material weakness described in the sixth paragraph of that report, as to which the date is July 18, 2008) expressed an adverse opinion on the effectiveness of internal control over financial reporting.

Notes to Consolidated Financial Statements

(expressed in U.S. dollars except as otherwise noted)

1. NATURE OF OPERATIONS AND GOING CONCERN UNCERTAINTY

Nature of Operations

OccuLogix, Inc. (“OccuLogix” or the “Company”) is an ophthalmic therapeutic company founded to commercialize innovative treatments for age-related eye diseases. Until recently, the Company operated two business divisions, being Retina and Glaucoma. Until recently, the Company’s Retina division was in the business of developing and commercializing a treatment for dry age-related macular degeneration, or Dry AMD. The Company’s product for Dry AMD, the RHEO™ System, contains a pump that circulates blood through two filters and is used to perform the Rheopheresis™ procedure, which is referred to under the Company’s trade name RHEO™ Therapy. The Rheopheresis™ procedure is a blood filtration procedure that selectively removes molecules from plasma, which is designed to treat Dry AMD, the most common form of the disease.

The Company conducted a clinical trial, called MIRA-1, or Multicenter Investigation of Rheopheresis for AMD, which, if successful, was expected to support its application with the U.S. Food and Drug Administration (the “FDA”) to obtain approval to market the RHEO™ System in the United States. On February 3, 2006, the Company announced that, based on a preliminary analysis of the data from MIRA-1, MIRA-1 did not meet its primary efficacy endpoint as it did not demonstrate a statistically significant difference in the mean change of Best Spectacle-Corrected Visual Acuity applying the Early Treatment Diabetic Retinopathy Scale, or ETDRS BCVA, between the treated and placebo groups in MIRA-1 at 12 months post-baseline. As expected, the treated group demonstrated a positive result. An anomalous response of the control group is the principal reason why the primary efficacy endpoint was not met.

On June 8, 2006, the Company met with the FDA to discuss the results of MIRA-1 and the impact the results will have on its application to market the RHEO™ System in the United States. In light of MIRA-1’s failure to meet its primary efficacy endpoint, the FDA advised that it will require an additional study of the RHEO™ System to be performed. On January 29, 2007, the Company announced that it had obtained Investigational Device Exemption clearance from the FDA to commence the new pivotal clinical trial of the RHEO™ System called RHEO-AMD, or Safety and Effectiveness in a Multi-Center, Randomized, Sham-Controlled Investigation for Dry Non-exudative Age-Related Macular Degeneration (AMD) using Rheopheresis.

However, on November 1, 2007, the Company announced the indefinite suspension of its RHEO™ System clinical development program. This decision was made following a comprehensive review of the respective costs and development timelines associated with the products in the Company’s portfolio and in light of the Company’s financial position. The Company is in the process of winding down the RHEO-AMD study as there is no reasonable prospect that the RHEO™ System clinical development program will be relaunched in the foreseeable future. Subsequent to the Company’s fiscal 2007 year-end, as of February 25, 2008, the Company has terminated its relationship with Asahi Kasei Kuraray Medical Co., Ltd. (formerly Asahi Kasei Medical Co., Ltd.), or Asahi Medical. Asahi Medical manufactures and supplied the Company with the Rheofilter filter and the Plasmaflo filter, both of which are key components of the RHEO™ System. The Company is also engaged in discussions with Diamed Medizintechnik GmbH, or Diamed, and MeSys GmbH, or MeSys, regarding the termination of its relationship with each of them. Diamed is the designer, and MeSys is the manufacturer, of the OctoNova pump, another key component of the RHEO™ System.

In anticipation of the delay in the commercialization of the RHEO™ System in the United States as a result of the MIRA-1 study’s failure to meet its primary efficacy endpoint and the FDA’s requirement of the Company to conduct an additional study of the RHEO™ System, the Company accelerated its diversification plans and, on September 1, 2006, acquired Solx, Inc., or SOLX, a Boston University Photonics Center-incubated company that has developed a system for the treatment of glaucoma, called the SOLX Glaucoma System. The SOLX Glaucoma System developed by SOLX includes the SOLX 790 Titanium Sapphire Laser (“SOLX 790 Laser”) and the SOLX Gold Shunt which can be used separately or together to provide physicians with multiple options to manage intraocular pressure, or IOP (note 4). Upon the acquisition of SOLX, SOLX became the Glaucoma division of the Company.

On December 20, 2007, the Company announced the sale of all of the issued and outstanding capital stock of SOLX to Solx Acquisition, Inc., or Solx Acquisition, a company wholly owned by Doug P. Adams, the founder of SOLX and who, until the closing of the sale, had been serving as an executive officer of the Company in the capacity of President & Founder, Glaucoma Division. The consideration for the purchase and sale of all of the issued and outstanding shares of the capital stock of SOLX consisted of: (i) on December 19, 2007, the closing date of the sale, the assumption by Solx Acquisition of all of the liabilities of the Company, as they related to SOLX’s business, incurred on or after December 1, 2007, and the Company’s obligation to make a $5,000,000 payment to the former stockholders of SOLX due on September 1, 2008 in satisfaction of the outstanding balance of the purchase price of SOLX; (ii) on or prior to February 15, 2008, the payment by Solx Acquisition of all of the expenses that the Company had paid to the closing date, as they related to SOLX’s business during the period commencing on December 1, 2007; (iii) during the period commencing on the closing date and ending on the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 3% of the worldwide net sales of the SOLX 790 Laser and the SOLX Gold Shunt, including next-generation or future models or versions of these products; and (iv) following the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 5% of the worldwide net sales of these products. In order to secure the obligation of Solx Acquisition to make these royalty payments, SOLX granted to the Company a subordinated security interest in certain of its intellectual property. In connection with the sale of SOLX, those employees of the Company, whose roles and responsibilities related mainly to SOLX’s business, ceased to be employees of the Company and became employees of Solx Acquisition or SOLX.

As part of its accelerated diversification plans, on November 30, 2006, the Company acquired 50.1% of the capital stock, on a fully diluted basis, 57.62% on an issued and outstanding basis, of OcuSense, Inc., or OcuSense, a San Diego-based company that is in the process of developing technologies that will enable eye care practitioners to test, at the point-of-care, for highly sensitive and specific biomarkers using nanoliters of tear film (note 4).

With the suspension of the Company’s RHEO™ System clinical development program, and the consequent winding-down of the RHEO-AMD study, and the Company’s disposition of SOLX, the Company no longer has any operating business. Its major asset is its 50.1% ownership stake, on a fully diluted basis, in OcuSense.

Going concern uncertainty

The consolidated financial statements have been prepared on the basis that the Company will continue as a going concern. However, the Company has sustained substantial losses of $69,829,983, $82,221,897 and $162,829,981 for the years ended December 31, 2007, 2006 and 2005, respectively. The Company’s working capital deficiency at December 31, 2007 is $996,862, which represents a $14,535,888 reduction of its working capital of $13,539,026 at December 31, 2006. As a result of the Company’s history of losses and financial condition, there is substantial doubt about the ability of the Company to continue as a going concern.

On February 19, 2008, the Company announced that it has secured a bridge loan in an aggregate principal amount of $3,000,000 (less transaction costs of approximately $200,000) from a number of private parties. The loan bears interest at a rate of 12% per annum and has a 180-day term, which may be extended to 270 days under certain circumstances. The Company has pledged its shares of the capital stock of OcuSense as collateral for the loan.

Management believes that these proceeds, together with the Company’s existing cash, will be sufficient to cover its operating activities and other demands only until approximately the end of April 2008 (assuming that the outstanding obligation of OccuLogix to pay $2,000,000 to OcuSense becomes due and payable prior to the end of April 2008) (note 4). The Company currently is not generating cash from operations, and most of its cash has been, and is being, utilized to fund its operations and to fund deferred acquisition payments. The Company’s operating expenses have consisted mostly of expenses relating to the furtherance of its clinical trial activities, the commercialization of the SOLX Glaucoma System in Europe and the completion of the product development of the TearLab™ test for dry eye disease, or DED. Unless the Company raises additional capital, it will not have sufficient cash to support its operations beyond approximately the end of April 2008.

On October 9, 2007, the Company announced that its Board of Directors, or the Board (note 17(e)), had authorized management and the Company’s advisors to explore the full range of strategic alternatives available to enhance shareholder value. These alternatives may include, but are not limited to, the raising of capital through the sale of securities, one or more strategic alliances and the combination, sale or merger of all or part of OccuLogix. In making the announcement, the Company stated that there can be no assurance that the exploration of strategic alternatives will result in a transaction. To date, the Company has not disclosed, nor does it intend to disclose, developments with respect to its exploration of strategic alternatives unless and until the Board has approved a specific transaction.

For some time prior to the October 9, 2007 announcement, the Company had been seeking to raise additional capital, with the objective of securing funding sufficient to sustain its operations as it had been clear that, unless the Company was able to raise additional capital, the Company would not have had sufficient cash to support its operations beyond early 2008. The Board’s decisions to suspend the Company’s RHEO™ System clinical development program and to dispose of SOLX were made and implemented in order to conserve as much cash as possible while the Company continued its capital-raising efforts.

On January 9, 2008, the Company announced the departure, or pending departure, of seven members of its executive team and, commencing on February 1, 2008, a 50% reduction in the salary of each of Elias Vamvakas, its Chairman and Chief Executive Officer, and Tom Reeves, its President and Chief Operating Officer. By January 31, 2008, a total of 12 non-executive employees of the Company had left the Company’s employment.

As at December 31, 2007, the Company had investments in the aggregate principal amount of $1,900,000 which consist of investments in four separate asset-backed auction rate securities yielding an average return of 5.865% per annum. However, as a result of market conditions, all of these investments have recently failed to settle on their respective settlement dates and have been reset to be settled at a future date with an average maturity of 46 days. Due to the current lack of liquidity for asset-backed securities of this type, the Company has concluded that the carrying value of these investments was higher than their fair value as of December 31, 2007. Accordingly, these auction rate securities have been recorded at their estimated fair value of $863,750. The Company considers this to be an other-than-temporary reduction in the value. Accordingly, the loss associated with these auction rate securities of $1,036,250 has been included as an impairment of investments in the Company’s consolidated statement of operations for the year ended December 31, 2007. Although the Company continues to receive payment of interest earned on these securities, the Company does not know at the present time when it will be able to convert these investments into cash. Accordingly, management has classified these investments as a non-current asset on its consolidated balance sheet as of December 31, 2007. Management will continue to closely monitor these investments for future indications of further impairment. The illiquidity of these investments may have an adverse impact on the length of time during which the Company currently expects to be able to sustain its operations in the absence of an additional capital raise by the Company.

The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary if the Company were not able to continue in existence as a going concern.

2. RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS

A. Correction of an error related to the method of consolidation of OcuSense Inc.

Background Information

On November 30, 2006, OccuLogix acquired 1,754,589 Series A preferred shares of OcuSense. The purchase price of these shares was made up of two fixed payments of $2.0 million each to be made on the date of the closing of the transaction (i.e. November 30, 2006) and on January 3, 2007. In addition, subject to OcuSense achieving certain milestones, the Company was required to pay two additional milestone payments of $2.0 million each.

Upon acquiring the Series A preferred shares, OccuLogix and the existing common shareholders entered into a voting agreement. The voting agreement provides the founding shareholders of OcuSense, as defined in the voting agreement, with the right to appoint two board members and OccuLogix with the right to also appoint two directors. A selection of a fifth director is mutually agreed upon by both OccuLogix and the founding stockholders, each voting as a separate class. The voting agreement is subject to termination under the following scenarios: a) a change of control; b) majority approval of each of OccuLogix and the founding stockholders; and c) conversion of all outstanding shares of the Company’s preferred shares to common shares. OccuLogix has the ability to force the conversion of all of the preferred shares to common shares and thus has the ability to effect a termination of the voting agreement, but this would require conversion of its own preferred shares and the relinquishment of the rights and obligations associated with the preferred shares.

The rights and obligations of the Series A preferred shareholders are as follows:

·	Voting – Holders of the Series A preferred shares are entitled to vote on an as-converted basis. Each Series A preferred share is entitled to one vote per share.

·	Conversion features – Series A preferred shares are convertible to common shares on a one-for-one basis at the option of OccuLogix.

·	Dividends – The preferred shares are entitled to non-cumulative dividends at 8%, and additional dividends would be shared between common and preferred shares on a per-share basis.

·	Redemption features – Subsequent to November 30, 2011, the preferred shares may be redeemed at the option of OccuLogix, at the higher of the original issue price and the fair market value of the common shares into which the preferred shares could be converted.

·	Liquidation preferences – Series A preferred shares have a liquidation preference over common shares up to the original issue price of the preferred shares (including the milestone payments).

Immediately after the OccuLogix investment in OcuSense, OcuSense had the following capital structure:

Description	Number
Common shares		1,222,979
Series A preferred shares – OccuLogix		1,754,589
Series A preferred shares – Other unrelated parties		67,317
Total		3,044,885
Potentially dilutive instruments
Warrants		89,965
Stock options		367,311
Fully diluted		3,502,161

Interpretation and Related Accounting Treatment

Since November 30, 2006, the date of the acquisition, the Company has consolidated OcuSense on the basis of a voting control model, as a result of the fact that it owns more than 50% of the voting stock of OcuSense and that the Company has the ability to convert its Series A preferred shares into common shares, which would result in termination of the voting agreement between the founders and OccuLogix and which would result in OccuLogix gaining control of the board of directors.

However, after further consideration, the Company has now determined that, as a result of the voting agreement between OccuLogix and certain founding stockholders of OcuSense, OccuLogix is not able to exercise voting control as contemplated in ARB 51, “Consolidated Financial Statements” (“ARB 51”) unless the Company converts its Series A preferred shares. For purpose of assessing voting control in accordance with ARB 51, accounting principals generally accepted in the United States (“U.S. GAAP”) do not take into consideration such conversion rights. Accordingly OccuLogix does not have the ability to exercise control of OcuSense, in light of the voting agreement that currently exists between the founding stockholders and OccuLogix.

In addition to the above consideration, the Company also determined that OcuSense is a Variable Interest Entity and that OccuLogix is the primary beneficiary based on the following:

·	OcuSense is a development stage enterprise (as defined under FAS 7, “Accounting and Reporting by Development Stage Enterprises”) and therefore is not considered to be a business under U.S. GAAP. Accordingly, OcuSense is not subject to the business scope exception.

·	The Company noted that the holders of the Series A preferred shares (including OccuLogix) have the ability to redeem their shares at the greater of their original subscription price and their fair value on an as-converted basis. As such, their investment is not considered to be at-risk equity.

Additionally, as a result of the voting agreement between OccuLogix and the founding stockholders of OcuSense, voting control of OcuSense is shared between OccuLogix and OcuSense. Accordingly, the common stockholders, who represent the sole class of at-risk equity, cannot make decisions about an entity’s activities that have a significant effect on the success of the entity without the concurrence of OccuLogix.

FIN 46(R) requires that the enterprise which consolidates the VIE be the primary beneficiary of that entity. The primary beneficiary is the entity that will absorb a majority of the VIE’s expected losses, receive a majority of the entity’s expected returns, or both. At the time of acquisition, it was expected that the Company would contribute virtually all of the required funding until commercialization through the acquisition of the Series A preferred shares and future milestone payments as described above. The common stockholders were expected to make nominal equity contributions during this period. Therefore, based primarily on qualitative considerations, the Company believes that it is the primary beneficiary of OcuSense and should consolidate OcuSense using the variable interest model.

The Company has noted that the initial measurement of assets, liabilities and non-controlling interests under FIN 46(R) differs from that which is required under FAS 141, “Business Combinations”. In particular, under FIN 46(R), assets, liabilities and non-controlling interest shall be measured initially at their fair value. The Company previously recorded non-controlling interest based on the historical carrying values of OcuSense’s assets and liabilities, and as a result consolidation under FIN 46(R) will result in material revisions to the amounts previously reported in the Company’s consolidated financial statements.

Assets acquired and liabilities assumed consisted solely of working capital and of a technology intangible asset relating to patents owned by OcuSense. Before consideration of deferred tax, the fair value of the assets acquired was greater than the fair value of the liabilities assumed and the non-controlling interest. Because OcuSense does not comprise a business, as defined in Emerging Issues Task Force (“EITF”) 98-3, “Determining Whether a Nonmonetary Transaction Involves Receipt of Productive Assets or of a Business”, the Company applied the simultaneous equation method as per EITF 98-11, “Accounting for Acquired Temporary Differences in Certain Purchase Transactions That Are Not Accounted for as Business Combinations”, and adjusted the assigned value of the non-monetary assets acquired (consisting solely of the technology asset) to include the deferred tax liability.

The Company also considered the appropriate accounting for the milestone payments, as a result of the fact that it has determined that it should apply the initial measurement guidance in FIN 46(R). The Company notes that subsequent to initial consolidation, the milestone payment liability represents a contingent liability to a controlled subsidiary, and as such, the liability will eliminate on consolidation. Previously, the Company adjusted the minority interest at the date of each milestone payment to reflect the non-controlling interest’s share in the additional cash of the subsidiary, with an offsetting increase to the non-monetary assets acquired (consisting solely of the technology intangible asset) reflecting the increased actual cost of obtaining those non-monetary assets.

The Company notes that because the non-controlling interest is required to be measured at fair value on acquisition of OcuSense, the fair value of the milestone payments as of the date of acquisition will be embedded in the initial measurement of non-controlling interest. As such, it would be inappropriate to record additional minority interest based on the full amount of the milestone payment applicable to the minority interest. Accordingly, the Company has accounted for the milestone payments as follows:

The Company determined the fair value of the milestone payments on the date of acquisition, by incorporating the probability that the milestone payments will be made, as well as the time value associated with the planned settlement date of the payments.

Upon payment of the milestone payments, the Company recorded the minority interest portion of the change in fair value of the milestone payment (i.e. the minority interest portion of the ultimate value of the milestone payment less the initial fair value determination) as an expense, with a corresponding increase to minority interest, to reflect the additional value provided to the minority interest in excess of that contemplated on the acquisition date.

The impact of the above restatement on the Company’s unaudited quarterly financial information is presented in Note 22

B. Correction of an error related to accounting for stock options

In accordance with the U.S. Securities and Exchange Commission (the “SEC”) Staff Accounting Bulletin (“SAB”) No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements”, the Company’s comparative consolidated financial statements have been corrected to reflect the Company’s accounting for stock options granted during fiscal 2005 to certain consultants that were subject to performance conditions. The vesting of these options was contingent upon the attainment of FDA approval of the RHEO™ System. These stock options were accounted for in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 123 “Accounting for Stock-Based Compensation” (“SFAS No. 123”) and subsequently in accordance with SFAS No. 123(R) (revised 2004), “Stock-Based Compensation” (“SFAS No. 123R”) upon the Company’s adoption of SFAS No. 123(R) on January 1, 2006. The total fair value of these options was estimated at the date of grant and was being amortized, over the Company’s estimate of the expected vesting period, as stock-based compensation expense in the Company’s consolidated statements of operations. In preparing the consolidated financial statements for the year ended December 31, 2007, the Company noted that these options should have been accounted for in accordance with EITF 96-18, “Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services”, (“EITF 96-18”) which requires that if, on the measurement date of the award, the quantity or any of the terms of the equity instruments are dependent on the achievement of performance conditions which result in a range of fair values, the lowest aggregate amount should be used.

Based on the provisions of EITF 96-18, the Company concluded that no stock-based compensation expense should have been recorded for these options. Since the effect of the error on the individual prior periods’ consolidated financial statements was immaterial, the Company has adjusted the comparative consolidated financial statements of prior years to reflect the correction of this error without undertaking a restatement of the prior periods’ consolidated financial statements. The following financial statement line items for fiscal 2006 and 2005 were affected by the correction of the error:

3. SIGNIFICANT ACCOUNTING POLICIES

The consolidated financial statements have been prepared by management in conformity with U.S. GAAP.

Basis of consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany transactions and balances have been eliminated on consolidation.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Some of the Company’s more significant estimates include those related to uncollectible receivables, stock-based compensation, investments and its intangible assets. Actual results could differ from those estimates.

Revenue recognition

Prior to the Company’s announcement of the indefinite suspension of its RHEO™ System clinical development program, the Company recognized revenue from the sale of the RHEO™ System, which is comprised of OctoNova pumps and the related disposable treatment sets, and, prior to the Company’s disposition of SOLX on December 19, 2007, the Company recognized revenue from the sale of the components of the SOLX Glaucoma System which includes the SOLX 790 Laser and the SOLX Gold Shunt. The Company received a signed binding purchase order from its customers. The pricing was a negotiated amount between the Company and its customers. The Company sold the components of the SOLX Glaucoma System directly to physicians and also through distributors. Revenue has been reported net of distributors’ commissions.

The Company had the obligation to train its customers and to calibrate the OctoNova pumps delivered to them. Only upon the completion of these services did the Company recognize revenue for the pumps. The Company was also responsible for providing a one-year warranty on the OctoNova pumps, and the estimated cost of providing this service was accrued at the time revenue was recognized. The treatment sets and the components of the SOLX Glaucoma System did not require any additional servicing and revenue was recognized upon passage of title. However, the Company’s revenue recognition policy requires an assessment as to whether collectibility is reasonably assured, which requires the Company to evaluate the creditworthiness of its customers. The result of the assessment could materially impact the timing of revenue recognition.

Cost of goods sold

Cost of sales includes costs of goods sold and royalty costs. The Company’s cost of goods sold consists primarily of costs for the manufacture of the RHEO™ System, prior to the Company’s announcement of the indefinite suspension of its RHEO™ System clinical development program, and the SOLX Glaucoma System, prior to the Company’s disposition of SOLX on December 19, 2007. Cost of sales also includes the costs the Company incurs for the purchase of component parts from its suppliers, applicable freight and shipping costs, fees related to warehousing, logistics inventory management and recurring regulatory costs associated with conducting business and ISO certification. In addition to these direct costs, included in the cost of goods sold are licensing costs associated with distributing the RHEO™ System in Canada and minimum royalty payments due to Mr. Hans Stock and Dr. Richard Brunner that are only recoverable based on sufficient volume (notes 11 and 12).

Cash and cash equivalents

Cash and cash equivalents comprise cash on hand and highly liquid short-term investments with original maturities of 90 days or less at the date of purchase.

Investments

Investments consist of investments in auction rate securities. These investments are classified as available-for-sale securities and are recorded at fair value with unrealized gains or losses reported in accumulated other comprehensive income unless the fair value is determined to be less than the carrying value and that this reduction in value is other than temporary. In such circumstances, the reduction in the carrying value is included in the determination of net loss. All of the auction rate securities have contractual maturities of more than three years.

Bad debt reserves

The Company evaluates the collectibility of its accounts receivable based on a combination of factors. In cases where management is aware of circumstances that may impair a specific customer’s ability to meet its financial obligations to the Company, a specific allowance against amounts due to the Company is recorded, which reduces the net recognized receivable to the amount management reasonably believes will be collected. For all other customers, the Company recognizes allowances for doubtful accounts based on the length of time the receivables are past due, the current business environment and historical experience. As at December 31, 2007 and 2006, the Company had bad debt reserves of $172,992 and nil, respectively. The Company expensed amounts related to bad debt reserves of nil, nil and $518,852 during the years ended December 31, 2007, 2006 and 2005, respectively, and set up a provision for $172,992, nil and $530,445, representing invoices for products shipped, plus related taxes, to a customer during the years ended December 31, 2007, 2006 and 2005, respectively, for which revenue was not recognized due to the likelihood that the customer would not be able to pay for the amounts invoiced.

Inventory

The Company evaluates its ending inventory for estimated excess quantities and obsolescence, based on expected future sales levels and projections of future demand, with the excess inventory provided for. In addition, the Company assesses the impact of changing technology, market conditions and the question of whether recent transactions provide indicators as to whether the net realizable value of its inventory is below its recorded cost. In April 2006, the Company sold a number of treatment sets to Veris Health Sciences Inc. (“Veris”) at a price lower than the Company’s cost. Accordingly, the Company wrote down the value of its treatment sets to reflect this current net realizable value during the year ended December 31, 2006. In light of the Company’s current financial position, on November 1, 2007, the Company announced an indefinite suspension of the RHEO™ System clinical development program for Dry AMD. That decision was made following a comprehensive review of the respective costs and development timelines associated with the products in the Company’s portfolio and, in particular, the fact that, if the Company had been unable to raise additional capital, it would not have had sufficient cash to support its operations beyond early 2008. Accordingly, the Company has written down the value of its treatment sets and OctoNova pumps, the components of the RHEO™ System, to nil as of December 31, 2007 since the Company is not expected to be able to sell or utilize these treatment sets and OctoNova pumps prior to their expiration dates, in the case of the treatment sets, or before the technologies become outdated.

Fair value of financial instruments

Fair value of a financial instrument is defined as the amount at which the instrument could be exchanged in a current transaction between willing parties. The estimated fair values of cash and cash equivalents, amounts receivable, accounts payable, accrued liabilities and amounts due from and to stockholders approximate their carrying values due to the short-term maturities of these instruments.

Fixed assets

Fixed assets are recorded at cost less accumulated amortization. Amortization is calculated using the straight-line method, commencing when the assets become available for productive use, based on the following estimated useful lives:

Furniture and office equipment	2 – 7 years
Computer equipment and software	3 years
Leasehold improvements	Shorter of useful life or initial term of the lease
Medical equipment	1 – 5 years

Impairment of long-lived assets

The Company reviews its fixed assets and intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. When such an event occurs, management estimates the future undiscounted cash flows expected to result from the use of the asset and its eventual disposition. In the event the undiscounted cash flows are less than the carrying amount of the asset, an impairment loss equal to the excess of the carrying amount over the fair value is charged to operations.

The Company’s intangible assets as at December 31, 2007 are comprised of the value of the exclusive distribution agreements the Company had with Asahi Medical, Diamed and MeSys and the value of the TearLab™ technology acquired upon the acquisition of 50.1% of the capital stock of OcuSense on a fully diluted basis 57.62% on an issued and outstanding basis. The Company’s intangible assets are being amortized using the straight-line method over an estimated useful life of 10 years.

Patents and trademarks

Patents and trademarks are recorded at historical cost and are amortized using the straight-line method over their estimated useful lives, not to exceed 15 years.

Goodwill

Goodwill is not amortized and instead is subject to an annual impairment test. The Company’s annual impairment test is conducted effective October 1 and is evaluated between annual tests upon the occurrence of certain events or circumstances. Goodwill impairment is assessed based on a comparison of the fair value of the reporting unit to the underlying carrying value of the reporting unit’s net assets, including goodwill. When the carrying amount of the reporting unit exceeds its fair value, the fair value of the reporting unit’s goodwill is compared with its carrying amount to measure the amount of impairment loss, if any.

Foreign currency translation

The Company’s functional and reporting currency is the U.S. dollar. The assets and liabilities of the Company’s Canadian operations are maintained in U.S. dollars. Monetary assets and liabilities denominated in foreign currencies are translated into U.S. dollars at exchange rates in effect at the consolidated balance sheet dates, and non-monetary assets and liabilities are translated at exchange rates in effect on the date of the transaction. Revenue and expenses are translated into U.S. dollars at average exchange rates prevailing during the year. Resulting exchange gains and losses are included in net loss for the year and are not material in any of the years presented.

Clinical and regulatory costs

Clinical and regulatory costs attributable to the performance of contract services are recognized as the services are performed. Non-refundable, up-front fees paid in connection with these contracted services are deferred and recognized as an expense on a straight-line basis over the estimated term of the related contract.

Income taxes

On January 1, 2007, the Company adopted the provisions of Financial Accounting Standards Board (“FASB”) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes – An Interpretation of FASB Statement No. 109” (“FIN No. 48”). FIN No. 48 addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under FIN No. 48, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. FIN No. 48 also provides guidance on derecognition, classification, interest and penalties on income taxes and accounting in interim periods and requires increased disclosure.

As a result of the implementation of the provisions of FIN No. 48, the Company recognized a reduction to the January 1, 2007 deferred tax liability balance in the amount of $4.6 million with a corresponding reduction to accumulated deficit.

As of January 1, 2007, the Company had unrecognized tax benefits of $24.8 million which, if recognized, would favorably affect the Company’s effective tax rate.

When applicable, the Company recognizes accrued interest and penalties related to unrecognized tax benefits as other expense in its consolidated statements of operations, which is consistent with the recognition of these items in prior reporting periods. As of January 1, 2007, the Company did not have any liability for the payment of interest and penalties.

The Company does not expect a significant change in the amount of its unrecognized tax benefits within the next 12 months. Therefore, it is not expected that the change in the Company’s unrecognized tax benefits will have a significant impact on the results of operations or financial position of the Company.

However, a portion of the Company’s net operating losses may be subject to annual limitations as a result of the Company’s initial public offering and prior changes of control. Accordingly, until a formal analysis of the effect of the changes of control is performed, a portion of the income tax benefits recognized to date may be affected.

All federal income tax returns for the Company and its subsidiaries remain open since their respective dates of incorporation due to the existence of net operating losses. The Company and its subsidiaries have not been, nor are they currently, under examination by the Internal Revenue Service or the Canada Revenue Agency.

State and provincial income tax returns are generally subject to examination for a period of between three and five years after their filing. However, due to the existence of net operating losses, all state income tax returns of the Company and its subsidiaries since their respective dates of incorporation are subject to re-assessment. The state impact of any federal changes remains subject to examination by various states for a period of up to one year after formal notification to the states. The Company and its subsidiaries have not been, nor are they currently, under examination by any state tax authority.

Stock-based compensation

The Company accounts for stock-based compensation expense for its employees in accordance with the provisions of SFAS No. 123R. Under the fair value recognition provision of SFAS No. 123R, stock-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as an expense ratably over the requisite service period of the award. The Company has selected the Black-Scholes option-pricing model as its method of determining the fair value for all its awards and will recognize compensation cost on a straight-line basis over the awards’ vesting periods (note 16(e)).

Net loss per share

The Company follows SFAS No. 128, “Earnings Per Share” (“SFAS No. 128”). In accordance with SFAS No. 128, companies that are publicly held or have complex capital structures are required to present basic and diluted earnings per share (“EPS”) on the face of the statement of income. Basic EPS excludes dilution and is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding for the year. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted and the resulting additional shares are dilutive because their inclusion decreases the amount of EPS.

The following are potentially dilutive securities which have not been used in the calculation of diluted loss per share as they are anti-dilutive:

Stock options		4,787,387	4,237,221	4,107,614
Warrants		2,764,416	—	—

Comprehensive income

The Company follows SFAS No. 130, “Reporting Comprehensive Income” (“SFAS No. 130”). SFAS No. 130 establishes standards for reporting and the presentation of comprehensive income and its components in a full set of financial statements. SFAS No. 130 requires only additional disclosures in the financial statements and does not affect the Company’s financial position or results of operations.

Comparative figures

Certain of the comparative figures have been reclassified to conform to the current year’s method of presentation and to reflect the effect of discontinued operations.

Recent accounting pronouncements

The adoption of SAB No. 110, “Share-based payments”, during fiscal 2007 did not have a material impact on the Company’s results of operations and financial position.

In September 2006, FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS No. 157”). SFAS No. 157 defines fair value, establishes a framework and gives guidance regarding the methods used for measuring fair value, and expands disclosures about fair value measurements. SFAS No. 157 is effective for financial statements issued for fiscal years beginning on or after November 15, 2007 and for interim periods within those fiscal years. On February 12, 2008, FASB issued FASB Staff Position No. 157-2, “Effective Date of FASB Statement No 157” (FSP No. 157-2”). FSP No. 157-2 amends SFAS No. 157 to delay the effective date of SFAS No. 157 for non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually) for fiscal years beginning after November 15, 2008.

The Company is currently evaluating the impact that the adoption of SFAS No. 157, FSP No. 157-2 and FSP No. 157-1 will have on its results of operations and financial position.

In February 2007, FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115” (“SFAS No. 159”). SFAS No. 159 expands the use of fair value accounting but does not affect existing standards which require assets or liabilities to be carried at fair value. Under SFAS No. 159, a company may elect to use fair value to measure accounts and loans receivable, available-for-sale and held-to-maturity securities, equity method investments, accounts payable, guarantees and issued debt. Other eligible items include firm commitments for financial instruments that otherwise would not be recognized at inception and non-cash warranty obligations where a warrantor is permitted to pay a third party to provide the warranty goods or services. If the use of fair value is elected, any up-front costs and fees related to the item must be recognized in earnings and cannot be deferred (e.g., debt issue costs). The fair value election is irrevocable and generally made on an instrument-by-instrument basis, even if a company has similar instruments that it elects not to measure based on fair value. At the adoption date, unrealized gains and losses on existing items for which fair value has been elected are reported as a cumulative adjustment to beginning retained earnings. Subsequent to the adoption of SFAS No. 159, changes in fair value are recognized in earnings. SFAS No. 159 is effective for fiscal years beginning on or after November 15, 2007 and is required to be adopted by the Company in the first quarter of fiscal 2008. The adoption of SFAS No. 159 will not have a material impact on the Company’s results of operations and financial position.

In June 2007, FASB’s EITF issued EITF No. 06-11, “Accounting for Income Tax Benefits of Dividends on Share-Based Payment Awards” (“EITF No. 06-11”). EITF No. 06-11 requires that the tax benefits related to dividend equivalents paid on restricted stock units, which are expected to vest, be recorded as an increase to additional paid-in capital. EITF No. 06-11 is effective prospectively to the income tax benefits on dividends declared in fiscal years beginning on or after December 15, 2007. The Company is currently evaluating the impact the adoption of EITF No. 06-11 will have on its results of operations and financial position.

In December 2007, FASB issued SFAS No. 141R (revised 2007), “Business Combinations (a revision of Statement No. 141)” (“SFAS No. 141R”). SFAS No. 141R applies to all transactions or other events in which an entity obtains control of one or more businesses, including those business combinations achieved without the transfer of consideration. SFAS No. 141R retains the fundamental requirements in Statement No. 141 that the acquisition method of accounting be used for all business combinations. SFAS No. 141R expands the scope to include all business combinations and requires an acquirer to recognize the assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree at their fair values as of the acquisition date. In addition, SFAS No. 141R changes the way entities account for business combinations achieved in stages by requiring the identifiable assets and liabilities to be measured at their full fair values. Also, contractual contingencies and contingent consideration shall be measured at fair value at the acquisition date. SFAS No. 141R is effective on a prospective basis to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. The Company is currently evaluating the impact, if any, that the adoption of SFAS No. 141R will have on its results of operations and financial position.

In December 2007, FASB issued Statement No. 160, “Noncontrolling Interests in Consolidated Financial Statements - an amendment of ARB No. 51” (“SFAS No. 160”). SFAS No. 160 amends ARB 51 to establish accounting and reporting standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS No. 160 clarifies that a non-controlling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. Additionally, SFAS No. 160 requires that consolidated net income include the amounts attributable to both the parent and the non-controlling interest. SFAS No. 160 is effective for interim periods beginning on or after December 15, 2008. The Company is currently evaluating the impact, if any, that the adoption of SFAS No. 160 will have on its results of operations and financial position.

4. ACQUISITIONS

During the fiscal year ended December 31, 2006, the Company completed two acquisitions. The results of each purchase acquisition are included in the Company’s consolidated statements of operations from the date of each acquisition. There were no acquisitions made during fiscal 2007.

The Company’s acquisitions during fiscal 2006 are described below.

Solx, Inc.

On September 1, 2006, the Company acquired SOLX, a privately held company that has developed a system for the treatment of glaucoma. The SOLX Glaucoma System developed by SOLX includes the SOLX 790 Laser and the SOLX Gold Shunt which can be used separately or together to provide physicians with multiple options to manage intraocular pressure. The acquisition of SOLX represented an expansion of the Company’s ophthalmic product portfolio beyond the RHEO™ procedure for Dry AMD. The results of SOLX’s operations have been included in the Company’s consolidated financial statements since September 1, 2006.

The Company acquired SOLX by way of a merger, in connection with which the Company issued an aggregate of 8,399,983 shares of its common stock and paid $7,000,000 in cash to the stockholders of SOLX. The Company made an additional payment of $3,000,000 in cash on the first anniversary of the September 1, 2006 closing and was expected to make an additional payment of $5,000,000 in cash to the former stockholders of SOLX on the second anniversary of the September 1, 2006 closing. In addition, if SOLX received final FDA approval for the marketing and sale of the SOLX Gold Shunt on or prior to December 31, 2007, the Company was expected to make an additional payment of $5,000,000 in cash to the former stockholders of SOLX. The stock consideration was valued based on a per share price of $1.79, being the weighted-average closing sale price of the Company’s common stock as traded on the NASDAQ Global Market (“NASDAQ”) over the two-day trading period before and after August 1, 2006, being the date the terms of the acquisition of SOLX were agreed to and announced. The Company recorded the cash payment paid on the first anniversary of the closing date as a current liability as of December 31, 2006. The $5,000,000 due on the second anniversary of the closing date was recorded as a long-term liability at its present value, discounted at the incremental borrowing rate of the Company as at August 1, 2006. The difference between the discounted value and the $5,000,000 payable was being amortized using the effective yield method over the two-year period with the monthly expense being charged as an interest expense in the Company’s consolidated statements of operations. In accordance with SFAS No. 141, “Business Combinations”, the contingent payment of $5,000,000 was not included in the determination of the purchase price or recorded as a liability as the receipt of FDA approval for the marketing and sale of the SOLX Gold Shunt on or prior to December 31, 2007 was subject to many variables, the outcome of which was not determinable beyond reasonable doubt.

The total purchase price of $29,068,443, which included acquisition-related transaction costs of $851,279, was allocated as follows:

	$

Net tangible assets		(2,908,384	)
Deferred tax liability		(12,270,150	)
Intangible assets:
Shunt and laser technology		27,000,000
Regulatory and other		2,800,000
		14,621,466
Goodwill		14,446,977
		29,068,443

Acquisition-related transaction costs included investment banking, legal and accounting fees and other third-party costs directly related to the acquisition.

In estimating the fair value of the intangible assets acquired, the Company considered a number of factors, including discussion with SOLX management, review of historic financial information, future revenue and expense estimates and a review of the economic and competitive environment. As a result, the Company used the income approach to value SOLX’s shunt and laser technology (consisting of the SOLX Gold Shunt and the SOLX 790 Laser) and the cost approach to value the regulatory and other intangible assets acquired (note 8).

On December 19, 2007, the Company sold all of the issued and outstanding capital stock of SOLX to Solx Acquisition. The consideration for the purchase and sale of all of the issued and outstanding shares of the capital stock of SOLX consisted of: (i) on the closing date of the sale, the assumption by Solx Acquisition of all of the liabilities of the Company related to SOLX’s business, incurred on or after December 1, 2007, and the Company’s obligation to make a $5,000,000 payment to the former stockholders of SOLX due on September 1, 2008 in satisfaction of the outstanding balance of the purchase price of SOLX; (ii) on or prior to February 15, 2008, the payment by Solx Acquisition of all of the expenses that the Company had paid to the closing date, as they related to SOLX’s business during the period commencing on December 1, 2007; (iii) during the period commencing on the closing date and ending on the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 3% of the worldwide net sales of the SOLX 790 Laser and the SOLX Gold Shunt, including next-generation or future models or versions of these products; and (iv) following the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 5% of the worldwide net sales of these products. In order to secure the obligation of Solx Acquisition to make these royalty payments, SOLX granted to the Company a subordinated security interest in certain of its intellectual property. The results of operations of SOLX from September 1, 2006, the date the Company acquired SOLX, to December 19, 2007, the closing date of the sale, have been included in discontinued operations in the Company’s consolidated statements of operations (note 10).

OcuSense, Inc.

On November 30, 2006, the Company acquired 50.1% of the capital stock of OcuSense, measured on a fully diluted basis, and 57.62% measured on an issued and outstanding basis. OcuSense’s first product, which is currently under development, is a hand-held tear film test for the measurement of osmolarity, a quantitative and highly specific biomarker that has shown to correlate with dry eye disease, or DED. The test is known as the TearLab™ test for DED. The results of OcuSense’s operations have been included in the Company’s consolidated financial statements since November 30, 2006.

Pursuant to the terms of the Series A Preferred Stock Purchase Agreement (the "Series A Preferred Stock Purchase Agreement"), dated as of November 30, 2006, between OcuSense and the Company, the Company purchased 1,754,589 shares of OcuSense's Series A Preferred Stock, par value of $0.001 per share, representing 50.1% of OcuSense's capital stock on a fully diluted basis, and 57.62% on an issued and outstanding basis, for an initial purchase price of $4,000,000. OccuLogix paid $2,000,000 of the initial purchase price on the closing of the purchase, which took place on November 30, 2006 and paid $2,000,000, the balance of the initial purchase price, on January 3, 2007. In connection with the purchase, OccuLogix incurred transaction costs of $171,098, thus establishing the total initial purchase price at $4,171,098. In addition, pursuant to the Series A Stock Purchase Agreement, the Company was obligated to make two additional payments to OcuSense of $2,000,000 each, subject to OcuSense's achievement of two pre-defined milestones. In June 2007, the Company made the first of these $2,000,000 payments to OcuSense upon its achievement of the first of these two pre-defined milestones. The Company will make the second of these $2,000,000 payments upon the achievement by OcuSense of the second of the two pre-defined milestones, provided that that milestone is achieved prior to May 1, 2009.

OcuSense is considered to be a VIE and OccuLogix is considered to be the primary beneficiary of OcuSense’s activities. Accordingly, under FIN 46(R), the assets, liabilities and non-controlling interest shall be measured initially at their fair value.

Assets acquired and liabilities assumed consisted primarily of working capital and of a technology intangible asset relating to patents owned by OcuSense. Before consideration of deferred tax, the fair value of the assets acquired was greater than the fair value of the liabilities assumed and the non-controlling interest. Because OcuSense does not comprise a business, as defined in EITF 98-3, “Determining Whether a Nonmonetary Transaction Involves Receipt of Productive Assets or of a Business”, the Company applied the simultaneous equation method as per EITF 98-11, “Accounting for Acquired Temporary Differences in Certain Purchase Transactions That Are Not Accounted for as Business Combinations”, and adjusted the assigned value of the non-monetary assets acquired (consisting solely of the technology asset) to include the deferred tax liability.

The fair values of OcuSense’s assets, liabilities and minority interest, at the date of acquisition, were as follows:

	As at November 30
	2006

Net tangible assets	$	2,690,316
Intangible assets	$	12,895,388
Deferred taxes	$	(5,158,155	)
Minority interest	$	(6,256,451	)
	$	4,171,098

In estimating the fair value of the intangible assets acquired, the Company considered a number of factors, including the valuation performed by an independent third-party valuator that used the income approach to value OcuSense’s TearLab™ technology (note 8).

5. GOODWILL

The Company follows the provisions of SFAS No. 142, “Goodwill and Other Intangible Assets” (“SFAS No. 142”), which requires that goodwill not be amortized but instead be tested for impairment at least annually and more frequently if circumstances indicate possible impairment.

The Company’s goodwill amount by reporting unit is as follows:

	Retina			Glaucoma			Total
	$			$			$

Balance, December 31, 2005		65,945,686			—			65,945,686
Acquired during the year		—			14,446,977			14,446,977
Impairment loss recognized		(65,945,686	)		—			(65,945,686	)
Balance, December 31, 2006		—			14,446,977			14,446,977
Impairment loss recognized		—			(14,446,977	)		(14,446,977	)
Balance, December 31, 2007		—			—			—

The Company performs its annual goodwill impairment analysis on its acquired goodwill on October 1 of each year and evaluates the carrying value of its goodwill between annual tests upon the occurrence of certain events and circumstances.

Retina

The Company conducted a pivotal clinical trial, called MIRA-1, which, if successful, was expected to support its application to the FDA to obtain approval to market the RHEO™ System in the United States. On February 3, 2006, the Company announced that, based on a preliminary analysis of the data from MIRA-1, MIRA-1 did not meet its primary efficacy endpoint as it did not demonstrate a statistically significant difference in the mean change of ETDRS BCVA between the treated and placebo groups in MIRA-1 at 12 months post-baseline. As a result of the announcement on February 3, 2006, the per share price of the Company’s common stock as traded on NASDAQ decreased from $12.75 on February 2, 2006 to close at $4.10 on February 3, 2006. The 10-day average price of the stock immediately following the announcement was $3.65 and reflected a decrease in the Company’s market capitalization from $536.6 million on February 2, 2006 to $153.6 million based on the 10-day average share price subsequent to the announcement. Based on this, the Company concluded that there were sufficient indicators to require management to re-assess whether the Company’s recorded goodwill was impaired as of December 31, 2005. Prior to the acquisition of SOLX and OcuSense during the second half of fiscal 2006, the Company was a single reporting unit. Therefore, management determined the fair value of the Company’s goodwill using the Company’s market capitalization as opposed to the fair value of its assets and liabilities. The Company recorded a goodwill impairment charge of $147,451,758 during the year ended December 31, 2005 as a result of a goodwill impairment re-assessment performed subsequent to the February 3, 2006 announcement.

On June 12, 2006, the Company announced that it met with the FDA to discuss the results of MIRA-1 and confirmed that the FDA will require the Company to perform an additional study of the RHEO™ System to obtain approval to market the RHEO™ System in the United States. In addition, on June 30, 2006, the Company announced that it had terminated negotiations with Sowood Capital Management LP in connection with a proposed private purchase of approximately $30,000,000 of zero-coupon convertible notes of the Company. In accordance with SFAS No. 142, the Company concluded that, based on the price of the Company’s common stock subsequent to the June 12, 2006 announcement and again after the June 30, 2006 announcement, there were sufficient indicators to require management to re-assess whether the Company’s recorded goodwill was impaired as at June 30, 2006. Based on the goodwill impairment analysis performed, the Company concluded that a further goodwill impairment charge of $65,945,686 should be recorded during the second quarter of 2006.

Glaucoma

On September 1, 2006, the Company acquired SOLX by way of a merger for a total purchase price of $29,068,443. Of this amount, $14,446,977 has been allocated to goodwill. On December 19, 2007, the Company sold to Solx Acquisition, and Solx Acquisition purchased from the Company, all of the issued and outstanding shares of the capital stock of SOLX, which had been the Glaucoma Division of the Company prior to the completion of the transactions provided for in the stock purchase agreement. The sale transaction established fair values for the Company’s recorded goodwill and certain of the Company’s intangible assets. Accordingly, the Company performed an impairment test of its recorded goodwill to re-assess whether its recorded goodwill was impaired as at December 1, 2007. Based on the goodwill impairment analysis performed, the Company concluded that a goodwill impairment charge of $14,446,977 should be recorded during the year ended December 31, 2007 to write down the value of its recorded goodwill to its fair value of nil (note 10).

Amortization expense was $844,948, $213,488 and $99,301 during the years ended December 31, 2007, 2006 and 2005, respectively, of which $231,542, $74,610 and nil is included as amortization expense of discontinued operations for the years ended December 31, 2007, 2006 and 2005, respectively (note 10).

On November 1, 2007, the Company announced an indefinite suspension of the RHEO™ System clinical development program for Dry AMD and is in the process of winding down the RHEO-AMD study as there is no reasonable prospect that the RHEO™ System clinical development program will be relaunched in the foreseeable future. In accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS No. 144”), the Company determined that the carrying value of certain of the Company’s medical equipment was not recoverable as of December 31, 2007. Accordingly, during the year ended December 31, 2007, the Company recorded a reduction to the carrying value of certain of its medical equipment of $431,683 which reflects a write-down of the value of this medical equipment to nil as of December 31, 2007. The assets written down were being used in the clinical trials of the RHEO™ System. The Company did not write down the carrying value of any of its fixed assets during the years ended December 31, 2006 and 2005.

Amortization expense was $195,494, $5,608 and $5,712 during the years ended December 31, 2007, 2006 and 2005, respectively.

Based on the November 1, 2007 announcement and in accordance with SFAS No. 144, the Company determined that the carrying value of certain of the Company’s patents and trademarks was not recoverable as of December 31, 2007. Accordingly, during the year ended December 31, 2007, the Company recorded a $190,873 reduction to the carrying value of its patents and trademarks related to the RHEO™ System, which reflects a write-down of these patents and trademarks to a value of nil as of December 31, 2007. The Company did not write down the carrying value of any of its patents and trademarks during the years ended December 31, 2006 and 2005.

The Company’s recorded patents and trademarks as of December 31, 2007 relate to the cost of pending applications for patents and trademarks for the TearLab™ technology. These patents and trademarks will be amortized, using the straight-line method, over an estimated useful life of 10 years from the date of approval of the patents and trademarks.

Estimated amortization expense for patents and trademarks for each of the next five years is as follows:

	Patents $		Trademarks $		Total $

2008		12,384		1,560		13,944

8. INTANGIBLE ASSETS

The Company’s intangible assets consist of the value of the exclusive distribution agreements that the Company has with its major suppliers and other acquisition-related intangibles. The Company has no indefinite-lived intangible assets. The distribution agreements were being amortized using the straight-line method over an estimated useful life of 15 years while the other acquisition-related intangible assets are amortized using the straight-line method over an estimated useful life of 10 years, respectively. Amortization expense for the years ended December 31, 2007, 2006 and 2005 was $5,308,706, $2,817,462 and $1,716,667, respectively, of which $2,731,667, $993,333 and nil is included as amortization expense of discontinued operations for the years ended December 31, 2007, 2006 and 2005, respectively (note 10).

2011		1,289,539
2012 and thereafter		5,926,898
		11,085,054

The Company’s intangible assets consist of the value of the exclusive distribution agreements the Company has with Asahi Medical, the manufacturer of the Rheofilter filters and the Plasmaflo filters, and Diamed and MeSys, the designer and the manufacturer, respectively, of the OctoNova pumps. The Rheofilter filter, the Plasmaflo filter and the OctoNova pump are components of the RHEO™ System, the Company’s product for the treatment of Dry AMD. On November 1, 2007, the Company announced an indefinite suspension of the RHEO™ System clinical development program for Dry AMD and is in the process of winding down the RHEO-AMD study as there is no reasonable prospect that the RHEO™ System clinical development program will be relaunched in the foreseeable future. In accordance with SFAS No. 144, the Company concluded that its indefinite suspension of the RHEO™ System clinical development program for Dry AMD was a significant event which may affect the carrying value of its distribution agreements. Accordingly, management was required to re-assess whether the carrying value of the Company’s distribution agreements was recoverable as of December 31, 2007. Based on management’s estimates of undiscounted cash flows associated with the distribution agreements, the Company concluded that the carrying value of the distribution agreements was not recoverable as of December 31, 2007. Accordingly, the Company recorded an impairment charge of $20,923,028 during the year ended December 31, 2007 to record the distribution agreements at their fair value as of December 31, 2007.

On December 19, 2007, the Company sold to Solx Acquisition all of the issued and outstanding shares of the capital stock of SOLX, which had been the Glaucoma Division of the Company prior to the completion of the transactions provided for in the stock purchase agreement. The sale transaction established fair values for the Company’s recorded goodwill and the Company’s shunt and laser technology and regulatory and other intangible assets acquired upon the acquisition of SOLX on September 1, 2006. Accordingly, management was required to re-assess whether the carrying value of the Company’s shunt and laser technology and regulatory and other intangible assets was recoverable as of December 1, 2007. Based on management’s estimates of undiscounted cash flows associated with these intangible assets, the Company concluded that the carrying value of these intangible assets was not recoverable as of December 1, 2007. Accordingly, the Company recorded an impairment charge of $22,286,383 during the year ended December 31, 2007 to record the shunt and laser technology and regulatory and other intangible assets at their fair value as of December 31, 2007 (note 10).

The Company determined that, as of December 31, 2007, there have been no significant events which may affect the carrying value of its TearLab™ technology. However, the Company’s prior history of losses and losses incurred during the current fiscal year reflects a potential indication of impairment, thus requiring management to assess whether the Company’s TearLab™ technology was impaired as of December 31, 2007. Based on management’s estimates of forecasted undiscounted cash flows as of December 31, 2007, the Company concluded that there is no indication of an impairment of the Company’s TearLab™ technology. Therefore, no impairment charge was recorded during the year ended December 31, 2007.

9. RESTRUCTURING CHARGES

In March 2006, the Company implemented a number of structural and management changes designed to then support both the continued development of its RHEO™ System and to execute its accelerated diversification strategy within ophthalmology. In accordance with SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities” (“SFAS No. 146”), the Company recognized a total of $819,642 in restructuring charges during the year ended December 31, 2006. The restructuring charges of $819,642 recorded during the year ended December 31, 2006 consist solely of severance and benefit costs related to the termination of a total of 12 employees at both the Company’s Mississauga, Ontario and Palm Harbor, Florida offices. All severance and benefit costs were fully paid as at December 31, 2006.

On January 9, 2008, the Company announced the termination of employment of certain members of its executive team in light of the Company’s current financial situation and in connection with the indefinite suspension of its RHEO™ System clinical development program and the sale of SOLX. In accordance with SFAS No. 146, the Company recognized a total of $1,312,721 in restructuring charges during the year ended December 31, 2007. The total restructuring charges of $1,312,721 recorded in the year ended December 31, 2007 consist solely of severance and benefit costs related to the termination of a total of eight employees at both the Company’s Mississauga, Ontario and Palm Harbor, Florida offices. All severance and benefit costs are yet to be paid as at December 31, 2007.

10. DISCONTINUED OPERATIONS

On December 19, 2007, the Company sold to Solx Acquisition, and Solx Acquisition purchased from the Company, all of the issued and outstanding shares of the capital stock of SOLX, which had been the Glaucoma Division of the Company prior to the completion of this transaction. The consideration for the purchase and sale of all of the issued and outstanding shares of the capital stock of SOLX consisted of: (i) on the closing date of the sale, the assumption by Solx Acquisition of all of the liabilities of the Company related to SOLX’s business, incurred on or after December 1, 2007, and the Company’s obligation to make a $5,000,000 payment to the former stockholders of SOLX due on September 1, 2008 in satisfaction of the outstanding balance of the purchase price of SOLX; (ii) on or prior to February 15, 2008, the payment by Solx Acquisition of all of the expenses that the Company had paid to the closing date, as they related to SOLX’s business during the period commencing on December 1, 2007; (iii) during the period commencing on the closing date and ending on the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 3% of the worldwide net sales of the SOLX 790 Laser and the SOLX Gold Shunt, including next-generation or future models or versions of these products; and (iv) following the date on which SOLX achieves a positive cash flow, the payment by Solx Acquisition of a royalty equal to 5% of the worldwide net sales of these products. In order to secure the obligation of Solx Acquisition to make these royalty payments, SOLX granted to the Company a subordinated security interest in certain of its intellectual property. No value was assigned to the royalty payments as the determination of worldwide net sales of SOLX’s products is subject to significant uncertainty.

The sale transaction described above established fair values for certain of the Company’s acquisition-related intangible assets and goodwill. Accordingly, the Company performed an impairment test of these assets at December 1, 2007. Based on this analysis, during the year ended December 31, 2007, the Company recognized a non-cash goodwill impairment charge of $14,446,977 and an impairment charge of $22,286,383 to record its acquisition-related intangible assets at their fair value as of December 31, 2007 (notes 5 and 8).

12. RELATED PARTY TRANSACTIONS

The following are the Company’s related party transactions in addition to those disclosed in notes 10, 11 and 15.

(a)	RHEO Clinic Inc.

One of the Company’s primary customers had been RHEO Clinic Inc., a subsidiary of TLC Vision. RHEO Clinic Inc. used the RHEO™ System to treat patients for which it charged its customers (the patients) a per-treatment fee. During the third quarter of 2005, RHEO Clinic Inc. determined that it would no longer treat patients and subsequently sold certain of its assets to the Company at a purchase price of C$61,812, including all applicable taxes. In connection with that sale, the Company agreed to share equally in losses incurred by RHEO Clinic Inc., to a maximum of C$28,952, for assets that RHEO Clinic Inc. was not able to dispose of as of the agreed date, being December 31, 2005. On May 1, 2006, the Company paid RHEO Clinic Inc. C$31,859 which included the amount owing for losses incurred for the assets that RHEO Clinic Inc. was not able to dispose of as of the agreed date.

(b)	TLC Vision and Diamed

On June 25, 2003, the Company entered into agreements with TLC Vision and Diamed to issue grid debentures in the maximum aggregate principal amount of $12,000,000 in connection with the funding of the Company’s MIRA-1 and related clinical trials. $7,000,000 of the aggregate principal amount was convertible into shares of the Company’s common stock at a price of $0.98502 per share, and $5,000,000 of the aggregate principal amount was non-convertible.

The $5,000,000 portion of the $12,000,000 commitment which was not convertible into the Company’s common stock was not advanced and the commitment was terminated prior to the completion of the Company’s initial public offering of shares of its common stock. During the years ended December 31, 2004 and 2003, the Company issued grid debentures in an aggregate principal amount of $4,350,000 and $2,650,000 to TLC Vision and Diamed, respectively, under the convertible portion of the grid debentures. On December 8, 2004, as part of the corporate reorganization relating to the Company’s initial public offering, the Company issued 7,106,454 shares of its common stock to TLC Vision and Diamed, upon conversion of $7,000,000 of aggregate principal amount of convertible debentures at a conversion price of $0.98502 per share. Collectively, at December 31, 2007, the two companies have a combined 35.6% equity interest in the Company on a fully diluted basis.

(c)	Asahi Medical

The Company entered into a distributorship agreement (the “Distribution Agreement”), effective October 20, 2006, with Asahi Medical. The Distribution Agreement replaced the 2001 distributorship agreement between Asahi Medical and the Company, as supplemented and amended by the 2003, 2004 and 2005 Memoranda. Pursuant to the Distribution Agreement, the Company had distributorship rights to Asahi Medical's Plasmaflo filter and Asahi Medical's second-generation polysulfone Rheofilter filter on an exclusive basis in the United States, Mexico and certain Caribbean countries (collectively, “Territory 1-a”), on an exclusive basis in Canada, on an exclusive basis in Colombia, Venezuela, New Zealand, Australia (collectively, “Territory 2”) and on a non-exclusive basis in Italy.

On January 28, 2008, the Company disclosed that it was engaged in discussions with Asahi Medical to terminate the Distribution Agreement. The Company and Asahi Medical have entered into a termination agreement to terminate substantially all of their obligations under the Distribution Agreement on and as of February 25, 2008 (the “Termination Agreement”). Pursuant to the Termination Agreement, the Company and Asahi Medical have agreed to a mutual release of claims relating to the Distribution Agreement, other than any claims relating to certain provisions of the Distribution Agreement which survived its termination.

The Company received free inventory from Asahi Medical for purposes of the RHEO-AMD trial, the LEARN, or Long-term Efficacy in AMD from Rheopheresis in North America, trials and related clinical studies. The Company has accounted for this inventory at a value equivalent to the cost the Company has paid for the same filters purchased from Asahi Medical for purposes of commercial sales to the Company’s customers. The value of the free inventory received from Asahi Medical was $384,660 and nil for the years ended December 31, 2007 and 2006, respectively.

(d)	Mr. Hans Stock (note 11)

On February 21, 2002, the Company entered into an agreement with Mr. Stock as a result of his assistance in procuring a distributorship agreement for the filter products used in the RHEO™ System from Asahi Medical. Mr. Stock agreed to further assist the Company in procuring new product lines from Asahi Medical for marketing and distribution by the Company. The agreement will remain effective for a term consistent with the term of the distributorship agreement with Asahi Medical, and Mr. Stock will receive a 5% royalty payment on the purchase of the filters from Asahi Medical. During each of the years ended December 31, 2007 and 2006, the Company did not pay any amount to Mr. Stock as royalty fees. Included in due to stockholders at December 31, 2007 and 2006 is $48,022 and $48,022, respectively, due to Mr. Stock.

On June 25, 2002, the Company entered into a consulting agreement with Mr. Stock for the purpose of procuring a patent license for the extracorporeal applications in ophthalmic diseases for that period of time in which the patent was effective. Mr. Stock was entitled to 1.0% of total net revenue from the Company’s commercial sales of products sold in reliance and dependence upon the validity of the patent’s claims and rights in the United States. The Company agreed to make advance consulting payments to Mr. Stock of $50,000 annually, payable on a quarterly basis, to be credited against any and all future consulting payments payable in accordance with this agreement. Due to the uncertainty of future royalty payment requirements, all required payments to date have been expensed.

On August 6, 2004, the Company entered into a patent license and royalty agreement with Mr. Stock to obtain an exclusive license to U.S. Patent No. 6,245,038. The Company is required to make royalty payments totaling 1.5% of product sales to Mr. Stock, subject to minimum advance royalty payments of $12,500 per quarter. The advance payments are credited against future royalty payments to be made in accordance with the agreement. This agreement replaces the June 25, 2002 consulting agreement with Mr. Stock which provided for a royalty payment of 1% of product sales. During each of the years ended December 31, 2007 and 2006, the Company paid $50,000 to Mr. Stock as royalty fees. Included in due to stockholders at December 31, 2007 and 2006 is $12,500 and $12,500, respectively, due to Mr. Stock.

Other

On June 25, 2003, the Company entered into a reimbursement agreement with Apheresis Technologies, Inc. (“ATI”) pursuant to which employees of ATI, including Mr. John Cornish, one of the Company’s stockholders and its former Vice President, Operations, provided services to the Company and ATI is reimbursed for the applicable percentage of time the employees spend working for the Company. Effective April 1, 2005, the Company terminated its reimbursement agreement with ATI, as a result of which termination the Company no longer compensated ATI in respect of any salary paid to, or benefits provided to, Mr. Cornish by ATI. Until April 1, 2005, Mr. Cornish did not have an employment contract with the Company and received no direct compensation from the Company. On April 1, 2005, Mr. Cornish entered into an employment agreement with the Company under which he received an annual base salary of $106,450, representing compensation to him for devoting 80% of his time to the business and affairs of the Company. Effective June 1, 2005, the Company amended its employment agreement with Mr. Cornish such that he began to receive an annual base salary of $116,723, representing compensation to him for devoting 85% of his time to the business and affairs of the Company. Effective April 13, 2006, the Company further amended its employment agreement with Mr. Cornish such that his annual base salary was decreased to $68,660 in consideration of his devoting 50% of his time to the business and affairs of the Company. In light of the Company’s current financial situation, and in connection with the indefinite suspension of its RHEO™ System clinical development program and the sale of SOLX, the Company terminated the employment of Mr. Cornish effective January 4, 2008.

During the year ended December 31, 2007, ATI made available to the Company, upon request, the services of certain of ATI’s employees and consultants on a per diem basis. During the year ended December 31, 2007, the Company paid ATI $98,769 under this arrangement (2006 – nil). Included in accounts payable and accrued liabilities at December 31, 2007 and 2006 is $20,004 and $9,629, respectively, due to ATI.

Effective January 1, 2004, the Company entered into a rental agreement with Cornish Properties Corporation, a company owned and managed by Mr. Cornish, pursuant to which the Company leases space from Cornish Properties Corporation at $2,745 per month. The original term of the lease extended to December 31, 2005. On November 8, 2005, as provided for in the rental agreement, the Company extended the term of the rental agreement with Cornish Properties Corporation for another year, ending December 31, 2006. On December 19, 2006, the Company extended the term of the rental agreement with Cornish Properties Corporation for another year, ending December 31, 2007, at a lease payment of $2,168 per month. During the years ended December 31, 2007 and 2006, the Company paid Cornish Properties Corporation an amount of $26,016 and $32,940, respectively, as rent.

On November 30, 2006, the Company announced that Mr. Elias Vamvakas, the Chairman, Chief Executive Officer and Secretary of the Company, had agreed to provide the Company with a standby commitment to purchase convertible debentures of the Company (“Convertible Debentures”) in an aggregate maximum amount of $8,000,000 (the “Total Commitment Amount”). Pursuant to the Summary of Terms and Conditions, executed and delivered as of November 30, 2006 by the Company and Mr. Vamvakas, during the 12-month commitment term commencing on November 30, 2006, upon no less than 45 days’ written notice by the Company to Mr. Vamvakas, Mr. Vamvakas was obligated to purchase Convertible Debentures in the aggregate principal amount specified in such written notice. A commitment fee of 200 basis points was payable by the Company on the undrawn portion of the Total Commitment Amount. Any Convertible Debentures purchased by Mr. Vamvakas would have carried an interest rate of 10% per annum and would have been convertible, at Mr. Vamvakas’ option, into shares of the Company’s common stock at a conversion price of $2.70 per share. The Summary of Terms and Conditions further provided that if the Company closes a financing with a third party, whether by way of debt, equity or otherwise and there are no Convertible Debentures outstanding, then the Total Commitment Amount was to be reduced automatically upon the closing of the financing by the lesser of: (i) the Total Commitment Amount; and (ii) the net proceeds of the financing. On February 6, 2007, the Company raised gross proceeds in the amount of $10,016,000 in a private placement of shares of its common stock and warrants. The Total Commitment Amount was therefore reduced to zero, thus effectively terminating Mr. Vamvakas’ standby commitment. No portion of the standby commitment was ever drawn down by the Company, and the Company paid Mr. Vamvakas a total of $29,808 in commitment fees in February 2007.

The Company entered into a consultancy and non-competition agreement on July 1, 2003 with the Center for Clinical Research (“CCR”), then a significant stockholder of the Company, which requires the Company to pay a fee of $5,000 per month. For the year ended December 31, 2003, CCR agreed to forego the payment of $75,250 due to it in exchange for options to purchase 20,926 shares of the Company’s common stock at an exercise price of $0.13 per share. In addition, CCR agreed to the repayment of the balance of $150,500 due to it at a rate of $7,500 per month beginning in July 2003. On August 22, 2005, the Company amended the consultancy and non-competition agreement with CCR such that the fee payable to it was increased from $5,000 to $15,000 per month effective January 1, 2005. The monthly fee is fixed regardless of actual time incurred by CCR in performance of the services rendered to the Company. The agreement allows either party to convert the payment arrangement to a fee of $2,500 daily. In the event of such conversion, CCR shall provide services on a daily basis as required by the Company and will invoice the Company for the total number of days that services were provided in that month. The amended consultancy and non-competition agreement provides for the payment of a one-time bonus of $200,000 upon receipt by the Company of FDA approval of the RHEO™ System and the grant of 60,000 options to CCR at an exercise price of $7.15 per share. The stockholders of the Company approved the adjustment of the exercise price of these options to $2.05 per share on June 23, 2006. These options were scheduled to vest as to 100% when and if the Company receives FDA approval of the RHEO™ System on or before November 30, 2006, as to 80% when and if the Company receives FDA approval after November 30, 2006 but on or before January 31, 2007 and as to 60% when and if the Company receives FDA approval after January 31, 2007. In August 2006, by letter agreement between the Company and CCR, it was agreed that the monthly fee of $15,000 would be suspended at the end of August 2006 until CCR’s services are required by the Company in the future. This resulted in a consulting expense, included within clinical and regulatory expense for the years ended December 31, 2007 and 2006, of $10,000 and $125,000, respectively.

On September 29, 2004, the Company signed a product purchase agreement with Veris for its purchase from the Company of 8,004 treatment sets over the period from October 2004 to December 2005, a transaction valued at $6,003,000, after introductory rebates. However, due to delays in opening its planned number of clinics throughout Canada, Veris no longer required the contracted-for number of treatment sets in the period. The Company agreed to the original pricing for the reduced number of treatment sets required in the period. Dr. Jeffrey Machat, who is an investor in, and one of the directors of, Veris, was a co-founder and former director of TLC Vision. In December 2005, by letter agreement, the Company agreed to the volume and other terms for the purchase and sale of treatment sets and pumps for the period ending February 28, 2006. As of December 31, 2005, the Company had received a total of $1,779,566 from Veris. Included in amounts receivable, net at December 31, 2005 was $1,049,297 due from Veris for the purchase of additional pumps and treatment sets. Veris agreed to the payment of interest at the rate of 8% per annum on all amounts outstanding for more than 45 days up to March 31, 2006, the expected date of final payment. In January 2006, the Company received from Veris an interest payment of $4,495 on amounts outstanding for more than 45 days to December 31, 2005. On February 3, 2006, the Company announced that the MIRA-1 clinical trial had not met its primary efficacy endpoint and that it would be more likely than not that the Company will be required to conduct a follow-up clinical trial of the RHEO™ System in order to support its Pre-Market Approval application to the FDA. Because of this delay in being able to pursue commercialization of the RHEO™ System in the United States and the resulting market reaction to this news and based on discussions with Veris, the Company believed that Veris would not be able to meet its financial obligations to the Company. Therefore, during the year ended December 31, 2005, the Company recorded an allowance for doubtful accounts of $1,049,297 against the amount due from Veris and did not accrue additional interest on the amount outstanding during the year ended December 31, 2006.

101

In April 2006, the Company agreed to sell a total of 1,000 treatment sets, with a negotiated discount, to Veris at a price of $200 per treatment set, which is lower than the Company’s cost. It was also agreed that payment for the treatment sets must be received by the Company in advance of shipment. In July 2006, Veris negotiated new payment terms with the Company, and it was agreed that payment for treatment sets shipped subsequent to June 2006 must be received within 60 days of shipment. The Company also agreed that all sales of treatment sets made to Veris to the end of 2006 will remain at the discounted price of $200 per treatment set. During the year ended December 31, 2006, the Company received a total of $171,800 from Veris for the purchase of 1,207 treatment sets. The sale of the treatment sets was included in revenue for the year ended December 31, 2006 as all the treatment sets had been delivered to Veris. In November 2006, the Company sold 348 treatment sets to Veris for $73,776, including applicable taxes, payment for which was not received by the Company within the agreed 60-day credit period. The sale of these treatment sets was not recognized as revenue during the year ended December 31, 2006 as the Company believed that Veris would not be able to meet its financial obligations to the Company. In January 2007, the Company met with the management of Veris and agreed to forgive the outstanding amount receivable of $73,776 for the purchase of 348 treatment sets delivered to Veris in November 2006. This amount was therefore not included in amounts receivable, net as of December 31, 2006. In addition, the Company recorded an inventory loss of $60,987 in the year ended December 31, 2006 for the sale of these 348 treatment sets since these treatment sets had been delivered to Veris already.

In June 2006, Veris returned four pumps which had been sold to it in December 2005. In fiscal 2005, the Company had recorded an inventory loss associated with all sales made to Veris in December 2005 and did not recognize revenue due to the Company’s anticipation that Veris may not return the products shipped to it and would not be able to pay for the amounts invoiced. Accordingly, during fiscal 2006, amounts receivable, net and the allowance for doubtful accounts recorded against the amount due from Veris have been reduced by the invoiced amount for the four pumps of $143,520. In addition, the cost of the four pumps returned by Veris, valued at $85,058, was used to reduce the cost of goods sold in the period.

On November 6, 2006, the Company amended its product purchase agreement with Veris and agreed to forgive the outstanding amount receivable of $904,101 from Veris which had been owing for the purchase of treatment sets and pumps and for related services delivered or provided to Veris during the period from September 14, 2005 to December 31, 2005. In consideration of the forgiveness of this debt, Veris agreed that the Company did not owe Veris any amounts whatsoever in connection with (i) the use by the Company of the leasehold premises located at 5280 Solar Drive in Mississauga, Ontario or (ii) legal fees and expenses incurred by Veris prior to February 14, 2006 with respect to certain of Veris’ trademarks that had been assigned to the Company, and licensed back to Veris, on February 14, 2006.

In March 2007, Veris negotiated new payment terms with the Company, and it was agreed that payment for treatment sets shipped subsequent to March 2007 must be received within 180 days of shipment. During the year ended December 31, 2007, the Company sold a total of 816 treatment sets to Veris, for a total amount of $172,992, plus applicable taxes. The sale of these treatment sets was not recognized as revenue during the year ended December 31, 2007 based on Veris’ payment history with the Company and the new 180-day payment terms agreed by Veris and the Company. In October 2007, the Company met with the management of Veris and, based on discussions with Veris, the Company believes that Veris will not be able to meet its financial obligations to the Company. Therefore, during the year ended December 31, 2007, the Company recorded an allowance for doubtful accounts of $172,992 against the total amount due from Veris for the purchase of these treatment sets.

102

The Company also entered into a clinical trial agreement on November 22, 2005 with Veris which required Veris to provide certain clinical trial services to the Company. The agreement provided for an advance payment of C$195,000 to Veris which represents 30% of the total value of the contract. The Company paid Veris C$195,000 on November 22, 2005 as provided for in the clinical trial agreement. This amount has been expensed during the year ended December 31, 2005 as the Company has suspended the clinical trial in question.

15. MINORITY INTEREST

As previously discussed in; Note 2A OcuSense was determined to be a VIE and OccuLogix was the primary beneficiary.

On acquisition of OcuSense, FIN 46(R) requires that the non-controlling interest be measured initially at fair value.

Minority interest reflects the initial fair value of the minority’s 42.38% interest in OcuSense’s net assets which are comprised of working capital and intangible assets as at the November 30, 2006 acquisition date, less the minority’s proportionate interest in losses incurred to date, plus the fair value of all vested options and warrants issued to parties other than OccuLogix as of the date of acquisition, as well as the value of options and warrants vested and issued after the acquisition date.

In addition, the Company has accounted for the milestone payments, made subsequent to the acquisition date, as follows:

The Company determined the fair value of the milestone payments on the date of acquisition by incorporating the probability that the milestone payments will be made, as well as the time value associated with the planned settlement date of the payments.

Upon payment of the milestone payments, the Company recorded the minority interest portion of the change in fair value of the milestone payment (i.e., the minority interest portion of the ultimate value of the milestone payment less the initial fair value determination) as an expense, with a corresponding increase to minority interest, to reflect the additional value provided to the minority interest in excess of that contemplated on the acquisition date.

16. COMMITMENTS AND CONTINGENCIES

Commitments

The Company has commitments relating to operating leases for rental of office space and equipment from unrelated parties. The total future minimum obligation under the various leases is $197,374 for 2008. Rent paid under these leases was $90,465, $80,329 and $60,207 for the years ended December 31, 2007, 2006 and 2005, respectively. All Canadian dollar amounts have been converted at the year-end exchange rate.

In May and June 2002, the Company entered into two separate agreements with Dr. Richard Brunner and Mr. Stock, respectively, to obtain the exclusive license to U.S. Patent No. 6,245,038. The Company is required to make royalty payments totaling 1.5% of product sales. The Company is required to make minimum advance quarterly royalty payments of $25,000 and amounts credited against future royalty payments to be made in accordance with the agreements. These agreements may be terminated by the Company upon the first to occur of:

(a)	all patents of the patent rights expiring, which is June 2017;

(b)	all patent claims of the patent rights being invalidated; or

(c)	the introduction of a similar competing technology deployed in the United States which could not be deterred by enforcement of the patent.

On August 6, 2004, the Company entered into a patent license and royalty agreement with Mr. Stock to obtain an exclusive license to U.S. Patent No. 6,245,038. The Company is required to make royalty payments totaling 1.5% of product sales to Mr. Stock, subject to minimum advance royalty payments of $12,500 per quarter. The advance payments are credited against future royalty payments to be made in accordance with the agreement. This agreement replaces the June 2002 consulting agreement with Mr. Stock, which provided for a royalty payment of 1% of product sales. This agreement effectively increases the total royalty payments required to be made in respect of U.S. Patent No. 6,245,038 to 2% of product sales (note 12).

Future minimum royalty payments under the agreements as at December 31, 2007 are approximately as follows:

	$
2008		100,000
2009		100,000
2010		100,000
2011		100,000
2012 and thereafter		550,000
		950,000

106

In addition, the Company entered into a consultancy and non-competition agreement on July 1, 2003 with CCR (note 12), which requires the Company to pay a fee of $5,000 per month. On August 22, 2005, the Company amended the consultancy and non-competition agreement with CCR such that the fee payable was increased from $5,000 to $15,000 per month effective January 1, 2005. The monthly fee is fixed regardless of actual time incurred by CCR in performance of the services rendered to the Company. The agreement allows either party to convert the payment arrangement to a fee of $2,500 daily. In the event of such conversion, CCR shall provide services on a daily basis as required by the Company and will invoice the Company for the total number of days that services were provided in that month. The amended consultancy and non-competition agreement provides for the payment of a one-time bonus of $200,000 upon receipt by the Company of FDA approval of the RHEO™ System and the grant of 60,000 options to CCR at an exercise price of $7.15 per share. The stockholders of the Company approved the adjustment of the exercise price of these options to $2.05 per share on June 23, 2006 (note 17(e)). These options were scheduled to vest as to 100% when and if the Company receives FDA approval of the RHEO™ System on or before November 30, 2006, as to 80% when and if the Company receives FDA approval after November 30, 2006 but on or before January 31, 2007 and as to 60% when and if the Company receives FDA approval after January 31, 2007. In August 2006, by letter agreement between the Company and CCR, it was agreed that the monthly fee of $15,000 would be suspended at the end of August 2006 until CCR’s services will be required by the Company in the future. The future minimum obligation under the consultancy and non-competition agreement for 2008 is therefore nil.

The Company entered into consulting agreements with individual members of its Scientific Advisory Board (“SAB”). The SAB was established in fiscal 2005 to advise the Company on its continuing research and development activities. In light of the Company’s financial position, on November 1, 2007, the Company announced an indefinite suspension of the RHEO™ System clinical development program for Dry AMD. That decision was made following a comprehensive review of the respective costs and development timelines associated with the products in the Company’s portfolio and, in particular, the fact that, if the Company were unable to raise additional capital, it would not have had sufficient cash to support its operations beyond early 2008. Accordingly, the Company terminated its agreements with the individual members of the SAB effective November 1, 2007. The future minimum obligation under the various consulting agreements is therefore nil. Consulting fees paid amounted to $218,929, $244,165 and nil for the years ended December 31, 2007, 2006 and 2005, respectively.

On November 30, 2006, pursuant to the Series A Preferred Stock Purchase Agreement between the Company and OcuSense, the Company purchased 1,744,223 shares of OcuSense’s Series A Preferred Stock representing 50.1% of OcuSense’s capital stock on a fully diluted basis, 57.62% on an issued and outstanding basis, for an aggregate purchase price of up to $8,000,000 (the “Purchase Price”). On the closing of the purchase which took place on November 30, 2006, the Company paid $2,000,000 of the Purchase Price. The Company paid another $2,000,000 installment of the Purchase Price on January 3, 2007. In June 2007, the Company paid the third $2,000,000 installment of the Purchase Price upon the attainment by OcuSense of the first of two pre-defined milestones. The Company is expected to pay the last $2,000,000 installment of the Purchase Price upon the attainment by OcuSense of the second of such milestones, provided that the milestone is achieved prior to May 1, 2009. The Series A Preferred Stock Purchase Agreement also makes provision for an ability on the part of the Company to increase its ownership interest in OcuSense for nominal consideration if OcuSense fails to meet certain milestones by specified dates. In addition, pursuant to the Series A Preferred Stock Purchase Agreement, the Company has agreed to purchase $3,000,000 of shares of OcuSense’s Series B Preferred Stock, which shall constitute 10% of OcuSense’s capital stock on a fully diluted basis at the time of purchase, upon OcuSense’s receipt from the FDA of 510(k) clearance for the TearLab™ test for DED and to purchase another $3,000,000 of shares of OcuSense’s Series B Preferred Stock, which shall constitute an additional 10% of OcuSense’s capital stock on a fully diluted basis at the time of purchase, upon OcuSense’s receipt from the FDA of Clinical Laboratory Improvement Amendments or CLIA, waiver for the TearLab™ test for DED (note 4).

On April 4, 2007, the Company entered into an independent contractor services agreement with Carol Jones for the purpose of providing consulting services for the Company’s clinical trial activities. The agreement requires the Company to pay a minimum fee of $1,750 per month during the period from April 4, 2007 to April 4, 2008. Future minimim obligation under the independent contractor services agreement is $24,500 for 2008.

107

On January 25, 2007, OcuSense entered into a consulting agreement with Dr. Michael Lemp which requires the Company to pay a consulting fee of $8,333 per month. Future minimim obligation under the consulting agreement is $100,000 for 2008.

On February 1, 2007, OcuSense entered into a consulting agreement with Nancy Cahill which requires the Company to pay a consulting fee of $1,000 per month. Future minimim obligation under the consulting agreement is $12,000 for 2008.

On September 17, 2007, OcuSense signed a letter of agreement with KAM Communications for the purpose of providing marketing support for the future launch of the TearLab™ test for DED which requires the Company to pay a monthly fee of $2,398. Future minimum obligation under the agreement is $16,786 for 2008.

Contingencies

During the ordinary course of business activities, the Company may be contingently liable for litigation and a party to claims. Management believes that adequate provisions have been made in the accounts where required. Although it is not possible to estimate the extent of potential costs and losses, if any, management believes that the ultimate resolution of any such contingencies will not have a material adverse effect on the financial position and results of operations of the Company.

Pursuant to the terms of the distribution agreement with MeSys, dated January 1, 2002, the Company undertook a commitment to purchase a minimum of 25 OctoNova pumps yearly, beginning after receipt of FDA approval of the RHEO™ System, representing an annual commitment of approximately $534,900. The marketing and distributorship agreement with Diamed provides for a minimum purchase of 1,000 OctoNova pumps during the period from the date of the agreement until the end of the five-year period following receipt of FDA approval, representing an aggregate commitment of €16,219,000, or approximately $23,871,935, based on exchange rates as of December 31, 2007. The Company is currently engaged in discussions with Diamed and MeSys regarding the termination of its relationship with each of them. Diamed is the designer, and MeSys is the manufacturer, of the OctoNova pump, one of the key components of the RHEO™ System.

17. CAPITAL STOCK

(a)	Authorized share capital

The total number of authorized shares of common stock of the Company is 75,000,000. Each share of common stock has a par value of $0.001 per share. The total number of authorized shares of preferred stock of the Company is 10,000,000. Each share of preferred stock has a par value of $0.001 per share.

(b)	Reorganizations

(i)

On July 18, 2002, the Company’s former parent company, OccuLogix Corp. (“Old OccuLogix”), merged with the Company, which was then a wholly-owned subsidiary of Old OccuLogix, to form OccuLogix, Inc. Pursuant to the merger, the Company effected a one-for-four stock split of its common and convertible preferred stock pursuant to which each share of Old OccuLogix common stock outstanding immediately prior to the merger was converted into one-fourth of one fully paid and non-assessable share of the Company’s common stock. Each outstanding share of Old OccuLogix Series A preferred stock was converted into one-fourth of one fully paid and non-assessable share of the Company’s Series A convertible preferred stock.

At the effective time of the merger, each outstanding warrant and option to purchase common stock of Old OccuLogix was assumed by the Company and converted into a warrant or option to purchase common stock of the Company, with appropriate adjustments to the exercise price and number of shares for which such warrants or options were exercisable.

108

(ii)

On December 8, 2004, the Company consummated certain reorganization transactions, which are collectively referred to as the “Reorganization” and which consisted of the following:

4,622,605 shares of common stock issued upon the automatic conversion of all outstanding shares of Series A and Series B convertible preferred stock;

7,106,454 shares of common stock issued to TLC Vision and Diamed upon conversion of $7,000,000 aggregate principal amount of convertible grid debentures held by them, the conversion price was $0.98502 per share; and

19,070,234 shares of common stock issued to TLC Vision in connection with the purchase by the Company of TLC Vision’s 50% interest in OccuLogix L.P. (the “Partnership”), this amount included 1,281,858 shares of common stock which were issued upon the exchange of shares of OccuLogix ExchangeCo ULC, one of the Company’s Canadian subsidiaries, issued for tax purposes to TLC Vision in connection with the Company’s purchase of TLC Vision’s interest in the Partnership.

Following the Reorganization, the Partnership’s U.S. business was carried on, and will continue to be carried on, by OccuLogix LLC, a Delaware limited liability company that is the Company’s wholly-owned, indirect subsidiary. The Partnership carried on the Canadian business until December 31, 2005.

The Company had licensed to the Partnership all of the distribution and marketing rights for the RHEO™ System for ophthalmic indications to which it is entitled. Prior to the Reorganization, the Company’s only profit stream came from its share of the Partnership’s earnings. The Company’s acquisition of TLC Vision’s 50% ownership interest in the Partnership, achieved through the Reorganization, moved the earnings potential for sales of the RHEO™ System to the Company.

(iii)

On December 31, 2005, the Partnership transferred all of its assets and liabilities, and assigned its right to develop and sell the RHEO™ System, to OccuLogix Canada Corp., a wholly-owned subsidiary of the Company. Following the transfer, the Partnership’s Canadian business will be carried on by OccuLogix Canada Corp. The Partnership and its general partner have subsequently been wound up.

(c)	Convertible preferred stock

Convertible preferred stockholders were entitled to one vote per share, on an “as-converted to common stock” basis. Each share of Series A and Series B Convertible Preferred Stock was entitled to receive a non-cumulative dividend of $0.411216 and $0.34698, respectively, prior to the payment of any dividend on common stock. Each share of Series A and Series B Convertible Preferred Stock was entitled to a liquidation preference of $4.836 and $3.5183, respectively, plus any declared but unpaid dividend before any payment could be made to holders of common stock.

After giving effect to the anti-dilution adjustment resulting from the issuance of the June 25, 2003 related party secured grid debentures (note 12), each share of Series A and Series B Convertible Preferred Stock was convertible into 1.678323 and 1.643683 shares of common stock, respectively, at the option of the holder. Each share of Series A and Series B Convertible Preferred Stock would automatically convert into shares of common stock at the conversion rate previously described if the Company obtained a firm underwriting commitment for an initial public offering. The conversion rate would be adjusted for stock dividends, stock splits and other dilutive events. Shares of Series A and Series B Convertible Preferred Stock would automatically convert in the event of sale of all or substantially all of the assets or capital stock of the Company.

(d)	Common stock

In December 2004, 5,600,000 shares of common stock of the Company at $12.00 per share were issued in connection with the initial public offering for gross cash proceeds of $67,200,000 (less issuance costs of $7,858,789).

On September 1, 2006, the Company issued 8,399,983 shares of its common stock to the former stockholders of SOLX in connection with the acquisition of SOLX. The stock consideration was valued based on a per share price of $1.79, being the weighted-average closing sale price of the Company’s common stock as traded on NASDAQ over the two-day trading period before and after August 1, 2006, being the date the terms of the acquisition of SOLX were agreed to and announced (note 4).

109

On February 1, 2007, the Company entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with certain institutional investors, pursuant to which the Company agreed to issue to those investors an aggregate of 6,677,333 shares of the Company’s common stock (the “Shares”) and five-year warrants exercisable into an aggregate of 2,670,933 shares of the Company’s common stock (the “Warrants”). The per share purchase price of the Shares was $1.50, and the per share exercise price of the Warrants is $2.20, subject to adjustment. The Warrants became exercisable on August 6, 2007. Pursuant to the Securities Purchase Agreement, on February 6, 2007, the Company issued the Shares and the Warrants. The gross proceeds of the sale of the Shares and the Warrants totaled $10,016,000 (less transaction costs of $871,215). On February 6, 2007, the Company also issued to Cowen and Company, LLC a five-year warrant exercisable into an aggregate of 93,483 shares of the Company’s common stock (the “Cowen Warrant”) in part payment of the placement fee payable to Cowen and Company, LLC for the services it had rendered as the placement agent in connection with the sale of the Shares and the Warrants. All of the terms and conditions of the Cowen Warrant (other than the number of shares of the Company’s common stock into which the Cowen Warrant is exercisable) are identical to those of the Warrants. The estimated grant date fair value of the Cowen Warrant of $97,222 is included in the transaction costs of $871,215 (note 17(f)).

As at December 31, 2007, the number of shares of common stock of the Company reserved for issuance upon the exercise of stock options is as follows:

Expiry date	Range of exercise prices $		#

2008		2.05	25,000
2009		2.00 – 2.05	167,625
2010		2.00 – 2.05	119,375
2012		0.80 – 2.00	96,090
2013		0.99 – 1.30	1,079,798
2014		2.05	675,000
2015		2.05	949,500
2016		1.77 – 2.14	728,749
2017		1.11 – 1.82	946,250
			4,787,387

(e)	Stock Option Plan

The Company has a stock option plan, the 2002 Stock Option Plan (the “Stock Option Plan”), which was most recently amended in June 2007 in order to, among other things, increase the share reserve under the Stock Option Plan by 2,000,000. Under the Stock Option Plan, up to 6,456,000 options are available for grant to employees, directors and consultants. Options granted under the Stock Option Plan may be either incentive stock options or non-statutory stock options. Under the terms of the Stock Option Plan, the exercise price per share for an incentive stock option shall not be less than the fair market value of a share of stock on the effective date of grant and the exercise price per share for non-statutory stock options shall not be less than 85% of the fair market value of a share of stock on the date of grant. No option granted to a holder of more than 10% of the Company’s common stock shall have an exercise price per share less than 110% of the fair market value of a share of stock on the effective date of grant.

Options granted may be time-based or performance-based options. The vesting of performance-based options is contingent upon meeting company-wide goals, including obtaining FDA approval of the RHEO™ System and the achievement of a minimum amount of sales over a specified period. Generally, options expire 10 years after the date of grant. No incentive stock options granted to a 10% owner optionee shall be exercisable after the expiration of five years after the effective date of grant of such option, no option granted to a prospective employee, prospective consultant or prospective director may become exercisable prior to the date on which such person commences service, and with the exception of an option granted to an officer, director or consultant, no option shall become exercisable at a rate less than 20% per annum over a period of five years from the effective date of grant of such option unless otherwise approved by the Board.

110

The Company has also issued options outside of the Stock Option Plan. These options were issued before the establishment of the Stock Option Plan, when the authorized limit of the Stock Option Plan was exceeded or as permitted under stock exchange rules when the Company was recruiting executives. In addition, options issued to companies for the purpose of settling amounts owing were issued outside of the Stock Option Plan, as the Stock Option Plan prohibited the granting of options to companies. The issuance of such options was approved by the Board and granted on terms and conditions similar to those options issued under the Stock Option Plan.

On January 1, 2006, the Company adopted the provisions of SFAS No. 123R, “Share-Based Payments”, requiring the recognition of expense related to the fair value of its stock-based compensation awards. The Company elected to use the modified prospective transition method as permitted by SFAS No. 123R and therefore has not restated its financial results for prior periods. Under this transition method, stock-based compensation expense for each of the years ended December 31, 2007 and 2006 includes compensation expense for all stock-based compensation awards granted prior to, but not yet vested, as of January 1, 2006, based on the grant-date fair value estimated in accordance with the original provisions of SFAS No. 123. Stock-based compensation expense for all stock-based compensation awards granted subsequent to January 1, 2006 was based on the grant-date fair value estimated in accordance with the provisions of SFAS No. 123R. The Company recognizes compensation expense for stock option awards on a straight-line basis over the requisite service period of the award.

The following table sets forth the total stock-based compensation expense resulting from stock options included in the Company’s consolidated statements of operations:

	December 31,
	2007		2006 (i)		2005 (ii)
	$		$		$

General and administrative		65,660		1,396,609		170,576
Clinical and regulatory		216,246		203,131		53,700
Sales and marketing		199,065		527,303		500
Stock-based compensation expense before income taxes (iii)(iv)		480,971		2,127,043		224,776

(i)

At the annual meeting of stockholders of the Company held on June 23, 2006, the stockholders of the Company approved the re-pricing of all then out-of-the-money stock options of the Company. Consequently, the exercise price of all outstanding stock options of the Company that, on June 23, 2006, was greater than $2.05, being the weighted-average trading price of the Company’s common stock on NASDAQ during the five-trading day period immediately preceding June 23, 2006, was adjusted downward to $2.05. 2,585,000 of the Company’s outstanding stock options with a weighted-average exercise price of $8.42 were affected by the re-pricing. SFAS No. 123R requires the re-pricing of equity awards to be treated as a modification of the original award and provides that such a modification is an exchange of the original award for a new award. SFAS No. 123R considers the modification to be the repurchase of the old award for a new award of equal or greater value, incurring additional compensation cost for any incremental value. This incremental difference in value is measured as the excess, if any, of the fair value of the modified award determined in accordance with the provisions of SFAS No. 123R over the fair value of the original award immediately before its terms are modified, measured based on the share price and other pertinent factors at that date. SFAS No. 123R provides that this incremental fair value, plus the remaining unrecognized compensation cost from the original measurement of the fair value of the old option, must be recognized over the remaining vesting period. Of the 2,585,000 options affected by the re-pricing, 1,401,073 were vested as at December 31, 2006. Therefore, additional compensation cost of $423,338 for the 1,401,073 stock options that were vested has been recognized and is included in the stock-based compensation expense for the year ended December 31, 2006.

In accordance with SFAS No. 123R, the Company also recorded compensation expense of $3,363 in the year ended December 31, 2006 as the Board approved accelerating the vesting of 1,250 unvested stock options granted to a terminated employee on April 28, 2006. SFAS No. 123R treats such a modification as a cancellation of the original unvested award and the grant of a new fully vested award as of that date.

111

(ii)

Stock-based compensation expense for the year ended December 31, 2005 relates primarily to compensation expense associated with non-employee stock options. The fair value of these options was determined using the Black-Scholes option-pricing model and was recorded in the Company’s consolidated statements of operations in accordance with the provisions of SFAS No. 123.

On December 11, 2005, the Board approved accelerating the vesting of unvested stock options granted prior to December 31, 2004 to employees, officers and directors. As a result of the vesting acceleration, options to purchase 438,561 shares of the Company’s common stock became exercisable immediately, including 308,611 held by executive officers, 48,958 held by non-employee directors and 80,992 held by other employees. These accelerated stock options represent approximately 30% of the total employee stock options of the Company that would not have been vested as at December 31, 2005. The weighted-average exercise price of the options that were accelerated was $11.78. The purpose of the acceleration was to enable the Company to avoid recognizing compensation expense associated with these options of $1,532,203 and $1,466,253 during the years ended December 31, 2006 and 2007, respectively, in its consolidated statements of operations as a result of the adoption of SFAS No. 123R on January 1, 2006. In accordance with Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB No. 25”), the Company recorded a compensation expense of $53,295 for the year ended December 31, 2005 as 9,033 of the total options, of which the vesting was accelerated, were “in-the-money” as at the date of the accelerated vesting. With respect to SFAS No. 123, the Company recognized, for purposes of pro forma disclosures, the incremental increase in fair value and the remaining balance of unrecognized compensation cost for the affected options at the time of acceleration.

In accordance with APB No. 25, the Company also recorded a compensation expense of $4,431 for the year ended December 31, 2005 as certain performance-based options granted to an employee and two directors were “in-the-money” as at December 31, 2005.

(iii)

The tax benefit associated with the Company’s stock-based compensation expense for the years ended December 31, 2007, 2006 and 2005 is $964,644, $781,527 and nil, respectively. This amount has not been recognized in the Company’s consolidated financial statements for the years ended December 31, 2007 and 2006 as there is a low probability that the Company will realize this benefit.

(iv)

Of the total stock-based compensation expense of $480,971, $2,127,043 and $224,776 included in the Company’s consolidated statements of operations for the years ended December 31, 2007, 2006 and 2005, respectively, $72,800, $36,287 and nil is included as stock-based compensation expense of discontinued operations for the years ended December 31, 2007, 2006 and 2005, respectively.

Net cash proceeds from the exercise of common stock options were $2,228, $270,935 and $231,235 for the years ended December 31, 2007, 2006 and 2005, respectively. No income tax benefit was realized from stock option exercises during the years ended December 31, 2007, 2006 and 2005. In accordance with SFAS No. 123R, the Company presents excess tax benefits from the exercise of stock options, if any, as financing cash flows rather than operating cash flows.

Prior to the adoption of SFAS No. 123R, the Company applied the provisions of SFAS No. 123, which allowed companies either to expense the estimated fair value of employee stock options or to follow the intrinsic value method as set forth in APB No. 25 but required companies to disclose the pro forma effects on net loss as if the fair value of the options had been expensed. The Company elected to apply APB No. 25 in accounting for employee stock options. Therefore, as required by SFAS No. 123, prior to the adoption of SFAS No. 123R, the Company provided pro forma net loss and pro forma net loss per share disclosures for stock-based awards as if the fair value of the options had been expensed.

The following table illustrates the pro forma net loss and net loss per share of common stock as if the fair value method had been applied to all awards during the year ended December 31, 2005:

	$

Net loss, as reported		(162,829,981	)

112

The weighted-average fair value of stock options granted during the years ended December 31, 2007, 2006 and 2005 was $0.90, $1.77 and $3.54, respectively. The estimated fair value was determined using the Black-Scholes option-pricing model with the following weighted-average assumptions:

	Years ended December 31,
	2007	2006	2005

Volatility	0.765	0.901	0.728
Expected life of options	5.85 years	5.56 years	2.33 years
Risk-free interest rate	4.87%	4.83%	3.87%
Dividend yield	0%	0%	0%

The Company’s computation of expected volatility for the years ended December 31, 2007, 2006 and 2005 is based on a comparable company’s historical stock prices as the Company did not have sufficient historical data. The Company’s computation of expected life has been estimated using the “short-cut approach” as provided in SAB No. 110 as options granted by the Company meet the criteria of “plain vanilla” options as defined in SAB No. 110. Under this approach, estimated life is calculated to be the mid-point between the vesting date and the end of the contractual period. The risk-free interest rate for an award is based on the U.S. Treasury yield curve with a term equal to the expected life of the award on the date of grant.

A summary of the options issued during the year ended December 31, 2007 and the total number of options outstanding as of that date and changes since December 31, 2004 are set forth below:

	Number of Options Outstanding			Weighted Average Exercise Price $		Weighted Average Remaining Contractual Life (years)		Aggregate Intrinsic Value $

Outstanding, December 31, 2004		2,749,199			4.64		8.31		—

113

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (i.e., the difference between the Company’s closing stock price on the last trading day of fiscal 2007 of $0.08 and the exercise price, multiplied by the number of shares that would have been received by the option holders if the options had been exercised on December 31, 2007). This amount is nil for all the years presented as the exercise price of all options outstanding as at December 31, 2007, 2006, 2005 and 2004 is higher than $0.08, the Company’s closing stock price on the last trading day of fiscal 2007.

As at December 31, 2007, $3,870,931 of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 1.85 years.

(f)

Warrants

On February 6, 2007, pursuant to the Securities Purchase Agreement between the Company and certain institutional investors (note 17(d)), the Company issued the Warrants to these investors. The Warrants are five-year warrants exercisable into an aggregate of 2,670,933 shares of the Company’s common stock. On February 6, 2007, the Company also issued the Cowen Warrant to Cowen and Company, LLC in part payment of the placement fee payable to Cowen and Company, LLC for the services it had rendered as the placement agent in connection with the private placement of the Shares and the Warrants pursuant to the Securities Purchase Agreement. The Cowen Warrant is a five-year warrant exercisable into an aggregate of 93,483 shares of the Company’s common stock. The per share exercise price of the Warrants is $2.20, subject to adjustment, and the Warrants became exercisable on August 6, 2007. All of the terms and conditions of the Cowen Warrant (other than the number of shares of the Company’s common stock into which it is exercisable) are identical to those of the Warrants.

The Company accounts for the Warrants and the Cowen Warrant in accordance with the provisions of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” (“SFAS No. 133”), along with related interpretation EITF No. 00-19, “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock” (“EITF No. 00-19”). SFAS No. 133 requires every derivative instrument within its scope (including certain derivative instruments embedded in other contracts) to be recorded on the balance sheet as either an asset or liability measured at its fair value, with changes in the derivative’s fair value recognized currently in earnings unless specific hedge accounting criteria are met. Based on the provisions of EITF No. 00-19, the Company determined that the Warrants and the Cowen Warrant do not meet the criteria for classification as equity. Accordingly, the Company has classified the Warrants and the Cowen Warrant as a current liability at December 31, 2007.

The estimated fair value of the Warrants and the Cowen Warrant was determined using the Black-Scholes option-pricing model with the following weighted-average assumptions:

Volatility		79.8%
Expected life of warrants		5 years
Risk-free interest rate		4.76%
Dividend yield		0%

The Company initially allocated the total proceeds received, pursuant to the Securities Purchase Agreement, to the Shares and the Warrants based on their relative fair values. This resulted in an allocation of $2,052,578 to obligation under warrants which includes the fair value of the Cowen Warrant of $97,222.

In addition, SFAS No. 133 requires the Company to record the outstanding derivatives at fair value at the end of each reporting period, resulting in an adjustment to the recorded liability of the derivative, with any gain or loss recorded in earnings of the applicable reporting period. The Company therefore estimated the fair value of the Warrants and the Cowen Warrant as at December 31, 2007 and determined the aggregate fair value to be a nominal amount, a decrease of approximately $2,052,578 over the initial measurement of the aggregate fair value of the Warrants and the Cowen Warrant on the date of issuance. Accordingly, the Company recognized a gain of $2,052,578 in its consolidated statement of operations for the year ended December 31, 2007 which reflects the decrease in the Company’s obligation to its warrant holders to its nominal amount at December 31, 2007.

114

Transaction costs associated with the issuance of the Warrants of $170,081 has been recorded as a warrant expense in the Company’s consolidated statement of operations for the year ended December 31, 2007.

A summary of the warrants issued during the year ended December 31, 2007 and the total number of warrants outstanding as of that date are set forth below:

	Number of warrants outstanding #		Weighted average exercise price $

19. FINANCIAL INSTRUMENTS

Currency risk

The Company’s activities which result in exposure to fluctuations in foreign currency exchange rates consist of the purchase of equipment from suppliers billing in foreign currencies. The Company does not use derivative financial instruments to reduce its currency risk.

Credit risk

The Company’s financial instruments that are exposed to concentration of credit risk consist primarily of cash and cash equivalents and amounts receivable. The Company maintains its accounts for cash with large low credit risk financial institutions in the United States and Canada in order to reduce its exposure.

During fiscal 2007, the Company derived all of its revenue from the sale of the components of the RHEO™ System and the SOLX Glaucoma System prior to the sale of all of the issued and outstanding shares of SOLX on December 19, 2007. During the year ended December 31, 2007, the Company sold components of the RHEO™ System to one of its customers, Veris. As previously discussed in note 12, the Company fully provided for the balance due from Veris. Accordingly, no trade receivables due from Veris have been recognized as at December 31, 2007.

20. SEGMENTED INFORMATION

As a result of the acquisition of SOLX and OcuSense during 2006 (note 4), the Company had three reportable segments: retina, glaucoma and point-of-care. The retina segment was in the business of commercializing the RHEO™ System which was used to perform the Rheopheresis™ procedure, a procedure that selectively removes molecules from plasma, which is designed to treat Dry AMD. The Company began limited commercialization of the RHEO™ System in Canada in 2003 and provided support to its sole customer in Canada, Veris, in its commercial activities in Canada. The Company obtained investigational device exemption clearance from the FDA to commence RHEO-AMD, its clinical study of the RHEO™ System. On November 1, 2007, the Company announced an indefinite suspension of the RHEO™ System clinical development program for Dry AMD. That decision was made following a comprehensive review of the respective costs and development timelines associated with the products in the Company’s portfolio and, in particular, the fact that, if the Company is unable to raise additional capital, it will not have sufficient cash to support its operations beyond approximately the end of April 2008 (assuming that the outstanding obligation of OccuLogix to pay $2,000,000 to OcuSense becomes due and payable prior to the end of April 2008) (note 4).

The glaucoma segment of the Company was in the business of providing treatment for glaucoma with the use of the components of the SOLX Glaucoma System which are used to provide physicians with multiple options to manage intraocular pressure. The Company was seeking to obtain 510(k) approval to market the components of the SOLX Glaucoma System in the United States. The Company acquired the glaucoma segment in the acquisition of SOLX on September 1, 2006; therefore, no amounts are shown for the segment in periods prior to September 1, 2006. On December 19, 2007, the Company sold all of the issued and outstanding shares of the capital stock of SOLX, which had been the glaucoma segment of the Company prior to the completion of this sale. All revenue and expenses related to the Company’s glaucoma segment, prior to the December 19, 2007 closing date, has therefore been included in discontinued operations on its consolidated statements of operations for the years ended December 31, 2007 and 2006.

The point-of-care segment is made up of the TearLab™ business which is currently developing technologies that enable eye care practitioners to test, at the point-of-care, for highly sensitive and specific biomarkers in tears using nanoliters of tear film. The Company acquired the TearLab™ business in the acquisition of 50.1% of the capital stock of OcuSense, on a fully diluted basis, 57.62% on an issued and outstanding basis, on November 30, 2006; therefore, no amounts are shown in periods prior to November 30, 2006. During the year ended December 31, 2006, the TearLab™ business did not meet the quantitative criteria to be disclosed separately as a reportable segment and was included as other.

The accounting policies of the segments are the same as those described in significant accounting policies (note 3). Intersegment sales and transfers are minimal and are accounted for at current market prices, as if the sales or transfers were to third parties.

The Company’s reportable units are strategic business units that offer different products and services. They are managed separately, because each business unit requires different technology and marketing strategies. The Company’s business units are acquired or developed as a unit, and in the case of SOLX and OcuSense, their respective management was retained at the time of acquisition.

21. SUBSEQUENT EVENTS

(i)

On February 19, 2008, the Company announced that it had secured a bridge loan in an aggregate principal amount of $3,000,000 (less transaction costs of approximately $200,000) from a number of private parties. The loan bears interest at a rate of 12% per annum and has a 180-day term, which may be extended to 270 days under certain circumstances. The Company has pledged its shares of the capital stock of OcuSense as collateral for the loan.

Under the terms of the loan agreement, the Company has two pre-payment options available to it, should it decide to not wait until the maturity date to repay the loan. Under the first pre-payment option, the Company may repay the loan in full by paying the lenders, in cash, the amount of outstanding principal and accrued interest and issuing to the lenders five-year warrants in an aggregate amount equal to approximately 19.9% of the issued and outstanding shares of the Company’s common stock (but not to exceed 20% of the issued and outstanding shares of the Company’s common stock). The warrants would be exercisable into shares of the Company’s common stock at an exercise price of $0.10 per share and would not become exercisable until the 180th day following their issuance. Under the second pre-payment option, provided that the Company has closed a private placement of shares of its common stock for aggregate gross proceeds of at least $4,000,000, the Company may repay the loan in full by issuing to the lenders shares of its common stock, in an aggregate amount equal to the amount of outstanding principal and accrued interest, at a 15% discount to the price paid by the private placement investors. Any exercise by the Company of the second pre-payment option would be subject to stockholder and regulatory approval.

(ii)

On September 18, 2007, OccuLogix received a letter from The Nasdaq Stock Market, or Nasdaq, indicating that, for the previous 30 consecutive business days, the bid price of the Company’s common stock closed below the minimum $1.00 per share requirement for continued inclusion under Marketplace Rule 4450(e)(5), or the Minimum Bid Price Rule. Therefore, in accordance with Marketplace Rule 4450(e)(2), the Company was provided 180 calendar days, or until March 17, 2008, to regain compliance. The Nasdaq letter stated that, if, at any time before March 17, 2008, the bid price of the Company’s common stock closes at $1.00 per share or more for a minimum of 10 consecutive business days, Nasdaq staff will provide written notification that it has achieved compliance with the Minimum Bid Price Rule. The Nasdaq letter also stated that, if the Company does not regain compliance with the Minimum Bid Price Rule by March 17, 2008, Nasdaq staff will provide written notification that the Company’s securities will be delisted, at which time the Company may appeal the Nasdaq staff’s determination to delist its securities to a Nasdaq Listing Qualifications Panel.

On February 1, 2008, the Company received a letter from The Nasdaq Stock Market, or Nasdaq, indicating that, for the previous 30 consecutive trading days, the Company’s common stock did not maintain a minimum market value of publicly held shares of $5,000,000 as required for continued inclusion by Marketplace Rule 4450(a)(2), or the MVPHS Rule. Therefore, in accordance with Marketplace Rule 4450(e)(1), the Company was provided 90 calendar days, or until May 1, 2008, to regain compliance. The Nasdaq letter stated that, if, at any time before May 1, 2008, the minimum market value of publicly held shares of the Company’s common stock is $5,000,000 or greater for a minimum of 10 consecutive trading days, Nasdaq staff will provide written notification that the Company complies with the MVPHS Rule. The Nasdaq letter also stated that, if the Company does not regain compliance with the MVPHS Rule by May 1, 2008, Nasdaq staff will provide written notification that the Company’s securities will be delisted, at which time the Company may appeal the Nasdaq staff’s determination to delist its securities to a Nasdaq Listing Qualifications Panel.

The Company will not have become compliant with the Minimum Bid Price Rule by March 17, 2008. Although the Company intends to appeal any determination by Nasdaq staff to delist its common stock to a Nasdaq Listing Qualifications Panel, the Company may not be successful in its appeal, in which case its common stock may be transferred to The Nasdaq Capital Market or be delisted altogether. Should either occur, existing stockholders will suffer decreased liquidity.

These Nasdaq notices have no effect on the listing of the Company’s common stock on the Toronto Stock Exchange.

ITEM 9.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

Not applicable.

ITEM 9A. CONTROLS AND PROCEDURES.

Management’s Consideration of the Restatement

Prior to filing this Amended Report, the Company’s management, with the participation of the Chief Executive Officer and Chief Financial Officer, reconsidered its conclusions regarding the effectiveness of disclosure controls and procedures and its internal control over financial reporting as at December 31, 2007 in light of and giving consideration to the facts and circumstances of the Restatement.

In assessing whether the Company’s disclosure controls and procedures and the Company’s internal control over financial reporting were effective as at December 31, 2007, management also considered the impact of the Restatement of its Financial Statements with respect to the method of consolidation used to account for its investment in OcuSense, Inc., to the consolidated financial statements for the fiscal years ended December 31, 2007 and 2006 as well as the Company’s control environment.

Management has concluded that due to the failure to account for the consolidation of OcuSense, Inc. under the variable interest entity model since the Company’s acquisition of OcuSense on November 30, 2006, there was a material weakness in its internal control over financial reporting as of December 31, 2007.

Accordingly, the Company’s management has concluded that the Company’s disclosure controls and procedures and internal control over financial reporting were not effective as of December 31, 2007.

During the period subsequent to December 31, 2007, the Company underwent significant changes, including the termination of employment of most of its employees, including finance department employees and senior executives. Despite the reduced resources at our disposal, using our remaining internal resources and engaging the services of outside consultants, we have focused our efforts on ensuring, to the fullest extent possible, that the Company has and maintains appropriate design and operating effectiveness of internal control over financial reporting. However, as is the case for many small companies, the Company may not have the resources to address fully complex financial accounting matters.

Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company’s reports under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefit of controls must be considered relative to their costs. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. The Company’s disclosure controls and procedures are designed to provide reasonable assurance of achieving their desired objectives, and the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are not effective to provide that reasonable assurance.

As of the end of the period covered by the report, the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act). Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that, as at December 31, 2007 the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) were not effective to provide reasonable assurance that the information required to be disclosed in the reports the Company files and submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

123

There have been no significant changes in the Company’s internal control over financial reporting that occurred during the year ended December 31, 2007, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of the Company is responsible for establishing and maintaining effective internal control over financial reporting as defined in Rule 13a-15(f) under the Exchange Act. The Company’s internal control over financial reporting is designed to provide reasonable assurance to the Company’s management and Board of Directors regarding the preparation and fair presentation of published financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

After the Company filed its Annual Report on Form 10-K for the year ended December 31, 2007, the Company identified an error in its previously issued audited consolidated financial statements and concluded that the financial statements included in the Annual Report on Form 10-K should be restated, as discussed in Note 2 to the consolidated financial statements included elsewhere in this Amended Report. The Company determined that this error resulted from a material weakness in the operating effectiveness of the Company’s internal control over financial reporting relative to the method of consolidation of its acquisition of OcuSense on November 30, 2006.

A material weakness is a control deficiency, or a combination of control deficiencies such that there is a reasonable possibility that a material misstatement of the annual of interim financial statements will not be prevented or detected.

As a result of the deficiency described above, the Company’s management has revised its earlier assessment and has now concluded that the Company had a material weakness as at December 31, 2007 and, therefore, the Company’s internal control over financial reporting was not effective as of such date.

The framework on which such re-evaluation was based is contained in the report entitled “Internal Control – Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO” Report”).

Management’s revised assessment of the effectiveness of internal control over financial reporting as of December 31, 2007, has been audited by Ernst & Young LLP, an independent registered public accounting firm who also audited the Company’s consolidated financial statements. As stated in the Report of Independent Registered Public Accounting Firm on Internal Controls, they have amended their opinion and now conclude that the Company has not maintained effective internal control over financial reporting as of December 31, 2007.

124

REPORT OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of OccuLogix, Inc.

We have audited OccuLogix, Inc.’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). OccuLogix, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s annual report on internal control over financial reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our report dated March 14, 2008, we expressed an unqualified opinion on the effectiveness of internal control over financial reporting. As described in the following paragraph, the Company subsequently identified a misstatement in its annual consolidated financial statements. Such matter was considered to be a material weakness as further discussed in the following paragraph. Accordingly, management has revised its assessment about the effectiveness of the Company’s internal control over financial reporting and our present opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2007, as expressed herein, is different from that expressed in our previous report.

A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. The following material weakness has been identified and included in management’s assessment. In its assessment as of December 31, 2007, management has concluded that the controls in place relating to the method of accounting for significant investments was not operating effectively to provide reasonable assurance that the provisions of FASB Interpretation No. 46(R), “Consolidation of Variable Interest Entitles” (“FIN 46(R)”), Accounting Research Bulletin No. 51, “Consolidated Financial Statements” and other authoritative US generally accepted accounting principles literature related to consolidation based on voting control would be properly applied, and that this is a material weakness in internal control over financial reporting. As a result, on July 18, 2008, the Company’s Board of Directors approved the restatement of the Company’s previously issued consolidated financial statements for the years ended December 31, 2007 and 2006. The restatement is described in note 2(a) to the consolidated financial statements.

125

This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2007 consolidated financial statements, and this report does not affect our report dated March 14, 2008, except for Note 2(a), as to which the date is July 18, 2008, on those consolidated financial statements.

In our opinion, because of the effect of the material weakness described above on the achievement of the objectives of the control criteria, OccuLogix, Inc. did not maintain effective internal control over financial reporting as of December 31, 2007 based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of OccuLogix, Inc. as of December 31, 2007 and 2006, and the related consolidated statements of operations, changes in stockholders’ equity and cash flows for each of the three years ended December 31, 2007 and our report dated March 14, 2008, except for note 2A, as to which the date is July 18, 2008, expressed an unqualified opinion thereon.
