Following the completion of the Reorganization and this offering (the time at which an investor would be interested), the Company believes that it will not have any further going concern issues, however, due to the retrospective nature of financial statements it will not be possible for our auditors to remove the going concern note from our financial statements.

The Company supplementally advises that while apheresis is a systemic therapy that does impact the entire body, it is important to know several decades of research supports the fact that this is a relatively safe procedure, particularly when Rheopheresis is an advancement involving a membrane filter that removes only select molecules from the blood. These molecules have been shown in epidemiological studies to be significantly elevated in patients manifesting AMD. - 35 - Further, patients in AMD trials in the United States and in Germany have been appropriately screened before every treatment and followed on a three-month schedule following the last treatment having labs determining their rheologic status (ensuring that the patients meet qualifications and the depletion of these molecules is not causing significant risks of side effects by being too low). (Sources: - Rheologic, Functional and Structural Aspects; Therapeutic Apheresis 2000; 4(5): 348-357 - Trans. Am. Ophthal. Soc 2002; 100: page 92 Table 3 - Therapeutic Apher Vol 4, No. 5, 2000 page 348) Clinical Studies - Page 46 64. CLARIFY WHETHER "LATE STAGE DRY AMD" MEANS CATEGORY 4, AS DEFINED EARLIER IN THE FILING.

PLEASE DESCRIBE IF THESE INSTITUTIONS OR WHOEVER LICENSES THE PROCEDURE FROM THESE INSTITUTIONS COULD BE YOUR POTENTIAL COMPETITOR. EXPLAIN WHY. None of the institutions that have conducted clinical trials could be the Company's competitor in the United States. The procedure that forms the basis of the Company's RHEO Therapy is protected by two patents. One of those patents is owned by the Company and the Company would not license this patent to anyone who would compete with it. The Company has the exclusive (even the owners may not use the patent in the United States) U.S. rights to use the other patent. In addition, there are two key components of the RHEO System, the OctoNova pump and the Rheofilter, that the Company has the exclusive North American rights to use (again, even the manufacturers may not use their products - 37 - to treat AMD in North America without violating their agreements with the Company). The Company also refers the Staff to the risk factor on page 13 of the Amended Form S-1 which describes the risk that the Company's patents may not be valid and the Company may not be able to obtain and enforce patents to protect their proprietary rights from use by competitors. Patents and Proprietary Rights - Page 51 67. YOU STATE THAT YOU WILL SEEK TO RE-EXAMINE THE PATENT LICENSED TO YOU. PLEASE EXPLAIN WHY YOU INTEND TO SEEK RE-EXAMINATION AND DESCRIBE IN DETAIL THE FACTS RELATED TO THIS MATTER. In response to the Staff's comments, the Company has revised the disclosure on page 56. Government Regulation - Page 53 68. WE NOTE THAT RHEO SYSTEM IS A CLASS III DEVICE, WHICH REQUIRES PMA APPROVAL. PLEASE DISCLOSE HOW LONG IT USUALLY TAKES TO ACQUIRE PMA APPROVAL, - 38 - WHEN YOU SUBMITTED YOUR APPLICATION FOR PMA APPROVAL, AND WHAT THE CURRENT STATUS IS. In response to the Staff's comments, the Company has revised the disclosure on page 57. In response to the Staff's comments, the Company supplementally advises the Staff that it has tried in various ways to formulate an acceptable estimate, but is concerned that the time that it takes for FDA to approve a PMA is so variable that it would be misleading to provide an estimate. The time to PMA approval depends very heavily on the product involved, the quality of and questions raised by the data, the acceptability of the manufacturing process, and the FDA's workload, to name just a few factors.

PLEASE IDENTIFY ANY MEMBERS OF THE UNDERWRITING SYNDICATE THAT WILL ENGAGE IN ANY ELECTRONIC OFFER, SALE OR DISTRIBUTION OF THE SHARES AND DESCRIBE THEIR PROCEDURES TO US SUPPLEMENTALLY. IF YOU BECOME AWARE OF ANY ADDITIONAL MEMBERS OF THE UNDERWRITING SYNDICATE THAT MAY ENGAGE IN ELECTRONIC OFFERS, SALES OR DISTRIBUTIONS AFTER YOU RESPOND TO THIS COMMENT, PROMPTLY SUPPLEMENT YOUR RESPONSE TO IDENTIFY THOSE MEMBERS AND PROVIDE US WITH A DESCRIPTION OF THEIR PROCEDURES. BRIEFLY DESCRIBE ANY ELECTRONIC DISTRIBUTION IN THE FILING. - 48 - ALSO, IN YOUR DISCUSSION OF THE PROCEDURES, TELL US HOW YOUR PROCEDURES ENSURE THAT THE DISTRIBUTION COMPLIES WITH SECTION 5 OF THE SECURITIES ACT. IN PARTICULAR: o THE COMMUNICATIONS USED; o THE AVAILABILITY OF THE PRELIMINARY PROSPECTUS; o THE MANNER OF CONDUCTING THE DISTRIBUTION AND SALE, LIKE THE USE OF INDICATIONS OF INTEREST OR CONDITIONAL OFFERS; AND o THE FUNDING OF AN ACCOUNT AND PAYMENT OF THE PURCHASE PRICE. FINALLY, TELL US WHETHER YOU OR THE UNDERWRITERS HAVE ANY ARRANGEMENTS WITH A THIRD PARTY TO HOST OR ACCESS YOUR PRELIMINARY PROSPECTUS ON THE INTERNET. IF SO, IDENTIFY THE PARTY AND THE WEBSITE, DESCRIBE THE MATERIAL TERMS OF YOUR AGREEMENT AND PROVIDE US WITH A COPY OF ANY WRITTEN AGREEMENT. PROVIDE US ALSO WITH COPIES OF ALL INFORMATION CONCERNING YOUR COMPANY OR PROSPECTUS THAT HAS APPEARED ON THEIR WEBSITE. AGAIN, IF YOU SUBSEQUENTLY ENTER INTO ANY ARRANGEMENTS LIKE THIS, PROMPTLY SUPPLEMENT YOUR RESPONSE. - 49 - Citigroup Global Markets Inc., SG Cowen & Co., LLC and ThinkEquity Partners LLC, the representatives of the underwriters, have advised the Company that the representatives do not intend to place a prospectus online or otherwise engage in an electronic distribution in connection with this offering. However, it is possible that an electronic prospectus may be posted by any member of the underwriting syndicate. Citigroup Global Markets Inc., the lead manager, has advised the Company that none of the agreements Citigroup Global Markets Inc. has with the other underwriters contractually limits the ability of those underwriters to make such a posting. Citigroup Global Markets Inc. also has advised the Company that it does not know which, if any, members of the syndicate may place a prospectus online or how they might choose to do so. The representatives currently know only who may be invited to join the syndicate and will not know the final composition of the syndicate or the allocation of shares until after the registration statement is declared effective. The Company has been advised by Citigroup Global Markets Inc. that each member of the syndicate of this offering will be an established firm, a registered broker/dealer and an NASD member. However, due to the nature of the syndicate process, the final syndicate list and allocations of shares will not be made until the day of pricing. Shortly after the registration statement is declared effective, pricing information is determined and communicated to those firms that have - 50 - expressed an interest in becoming syndicate members. After a relatively short period, in which these invitees can decline to participate in the syndicate on the negotiated terms, the final syndicate is established and allocations of shares are made. Prior to that time, Citigroup Global Markets Inc. knows only who has been invited to join the syndicate, but not the final composition of the syndicate or the allocation of the shares. Therefore, Citigroup Global Markets Inc. does not have an opportunity to make inquiry of the individual firms that will ultimately comprise the syndicate until after the relevance of their plans, if any, for Internet distribution have been mooted by the declaration of effectiveness of the registration statement. To address the Staff's concerns, Citigroup Global Markets Inc. will include in a communication to the syndicate the following: "The Securities and Exchange Commission has asked us to inform you that you may not make an online distribution of shares of OccuLogix, Inc.'s common stock unless you are following procedures for online distributions previously cleared with the Securities and Exchange Commission. By accepting an allocation from us, you will be deemed to be representing to us that either (i) you are not making an online distribution or (ii) you are following procedures for online distributions previously cleared with the Securities and Exchange Commission." - 51 - Given the responsibility of each broker/dealer to comply with all applicable Commission and NASD rules, including the recent releases and no-action letters on Internet distributions, and given the representations that will be received by Citigroup Global Markets Inc. that syndicate members will so comply, there would not appear to be a regulatory need to make Citigroup Global Markets Inc. responsible for the Internet activities of other syndicate members. Lead managers have not traditionally been viewed as responsible for the paper delivery activities of their syndicate members, and thus by analogy, it would seem unnecessary and inappropriate with respect to online distribution activities. The Company supplementally advises the Staff that neither the Company nor any of the underwriters have any arrangements with a third-party to host or access the preliminary prospectus on the Internet, other than in connection with plans to conduct an Internet roadshow through Net Roadshow, Inc. (www.netroadshow.com). While Citigroup Global Markets Inc. has contracted with Net Roadshow, Inc. to conduct an Internet roadshow, the purpose of such contract is not specifically to host or access the preliminary prospectus. The primary purpose of the Internet roadshow is to provide access to the roadshow to institutional customers who cannot, or elect not to, attend roadshow meetings in person. As part of the electronic roadshow process, an electronic version of the - 52 - preliminary prospectus (identical to the copy filed with the Commission and distributed to live attendees) is required to, and will, be made available on the web site. In its agreement with Citigroup Global Markets Inc., Net Roadshow, Inc. agrees to conduct Internet roadshows in accordance with the Net Roadshow, Inc. no-action letter, received from the Commission on September 8, 1997, and subsequent no-action letters from the Commission with respect to virtual roadshows. Citigroup Global Markets Inc. has previously provided to the Staff copies of its agreement with Net Roadshow, Inc. AUDITOR'S REPORT - PAGES F-2 AND F-40 90. REVISE TO INCLUDE SIGNED REPORTS OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM. REFER TO ITEM 302 OF REGULATION S-T WHICH, ADDRESSES SIGNATURES IN ELECTRONIC FILINGS In response to the Staff's comment, the Company has revised amended Form S-1 to include signed reports of the Independent Registered Public Accounting Firm, Ernst & Young LLP. - 53 - FINANCIAL STATEMENTS OF OCCULOGIX, INC. 91. PLEASE UPDATE THE FINANCIAL STATEMENTS AS REQUIRED BY RULE 3-12 OF REGULATION S-X. The Company has updated its financial statements as required by Rule 3-12. 92. PLEASE INCLUDE AN UPDATED ACCOUNTANT'S CONSENT IN THE AMENDED FILINGS. In response to the Staff's comment, an updated consent has been included with the amended filing. NOTE 2: SIGNIFICANT ACCOUNTING POLICIES REVENUE RECOGNITION - PAGE F-8 93. PLEASE EXPAND YOUR DISCLOSURE TO CLARIFY YOUR REVENUE RECOGNITION POLICY TO DISCUSS THE IMPACT OF RETURN POLICIES, POST SHIPMENT OBLIGATIONS INCLUDING TRAINING, CUSTOMER ACCEPTANCE, ETC., WARRANTIES AND CREDITS, DISCOUNTS, PRICE PROTECTION OR OTHER ARRANGEMENTS WITH THIRD PARTY DISTRIBUTORS. - 54 - In response to the Staff's comment, the Company has revised the disclosure on page F-8 to clarify its revenue recognition policy as follows: OccuLogix, Inc. Persuasive evidence of an arrangement refers to a signed legally binding agreement between the Company and OccuLogix, L.P. (the "Partnership") which stipulates not only pricing but also obligations of the Partnership and of the Company as they relate to the sales and distribution of the Company's products. As per this arrangement, the Company's obligation is to provide products (RHEO System components) to the Partnership at cost, while the Partnership is responsible for marketing and servicing the product. Included in the selling price of the Company's product to the Partnership are the freight cost, and cost of calibration. All related costs of revenue are accrued by the Company. The Company's customary business practice of recognizing revenue is FOB shipping as the Company does not retain any further significant obligation. The Partnership has a responsibility to provide the Company with forecasts and projections for a six month period of which the first three months of projections become fixed orders. - 55 - The agreement between the Company and the Partnership stipulates the selling price of the products from the Company to the Partnership to be at cost. OccuLogix, L.P. Persuasive evidence of an arrangement refers to a signed binding purchase order sent by the customer (RHEO Clinic Inc., Canadian Retinal Institute or Rheo Therapeutics Inc.) to the Partnership. Other than shipping the products, the Partnership has the obligation to calibrate the OctoNova pumps, which is considered to be a significant service. The Partnership's policy of recognizing revenue is upon the completion of this calibration process. All related costs of revenue are accrued by the Partnership. The pricing is a negotiated amount between the Partnership and its customers. The amount charged to RHEO Clinic Inc. (a related party) is consistent with those amounts charged to the Canadian Retinal Institute (a third party). The Partnership believes this amount to be indicative of fair market at this time. Post Sale Obligations: - 56 - OccuLogix, Inc. has no significant obligation other than to provide the products to the Partnership. All significant obligations are the responsibility of the Partnership. The most significant obligation of the Partnership is to calibrate the OctoNova pumps so that they can be used as intended. The filters do not require any additional servicing. Other potential obligations which may result from the sale of an OctoNova pump include initial training and an enhanced one year warranty that supplements the one that is offered by the manufacturer. The Partnership provides training prior to recognizing revenue, if required. With respect to the warranty, the Partnership accrues the estimated cost of providing this one year warranty service at the time revenue is recognized. The Company and the Partnership do not take into consideration returns, discounts and price protection as part of their revenue recognition policy. 94. IN ADDITION, CLARIFY WHY SHIPMENT IS THE APPROPRIATE POINT FOR REVENUE RECOGNITION. DOES LEGAL TITLE PASS UPON SHIPMENT? ARE THE TERMS FOB SHIPPING POINT? In response to the Staff's comment, the Company has revised the disclosure on page F-8. - 57 - INVESTMENTS IN LIMITED PARTNERSHIP - PAGE F-14 95. PLEASE REVISE TO INDICATE WHY YOU DO NOT CONSOLIDATE THE PARTNERSHIP AND, IF TRUE, WHAT FACTORS CAUSE YOU TO CONCLUDE YOU DO NOT HAVE CONTROL OVER THE PARTNERSHIP. WE NOTE THAT THE COMPANY PROVIDES MANAGEMENT ASSISTANCE TO THE PARTNERSHIP, FOR WHICH IT IS REMUNERATED, AND PRIOR TO THE OFFERING YOU WILL ACQUIRE THE REMAINING 50% INTEREST IN THE PARTNERSHIP FROM TLC. ALSO WE NOTE THAT ELIAS VAMVAKAS, IN JUNE 2003, BECAME THE CHAIRMAN AND SECRETARY FOR BOTH THE COMPANY AND THE PARTNERSHIP. WE MAY HAVE FURTHER COMMENTS UPON REVIEW OF YOUR RESPONSE. In response to the Staff's comment, the Company supplementally advises that in regards to its investment in OccuLogix, L.P., the Company considered the following authoritative guidance: o FAS 57 Related Party Disclosures; and o FIN 46 (R) Consolidation of Variable Interest Entities. Background - 58 - In 2002, the Company and TLC Vision entered into a joint venture agreement, structured as a limited partnership, for the purpose of pursuing commercial applications of technologies owned or licensed by the Company applicable to the evaluation, diagnosis, monitoring and treatment of dry age-related macular degeneration. Nature of Relationship Between Partners The Company and TLC Vision are considered to be related parties due to the following: o at December 31, 2003, TLC Vision owned approximately 8% of the total issued and outstanding shares of the Company. On a fully diluted basis, TLC Vision owned approximately 26% of the Company; and o Elias Vamvakas is Chairman of both TLC Vision and the Company. Treatment of Investment in OccuLogix, L.P. Through the joint venture agreement, the Company has an indirect 50% interest in the Partnership through its wholly owned subsidiary. However, TLC Vision's effective interest in the Partnership is greater than 50% when the interests held by - 59 - its wholly-owned subsidiaries, plus the interest held indirectly through its interest in the Company, are considered. Given that TLC Vision is the ultimate owner of greater than 50% of the investment in the Partnership, TLC Vision has consolidated its investment in the Partnership. Although technically the Company has a 50% interest in the Partnership, given TLC Vision's consolidation of the Partnership, TLC Vision's larger effective interest and common board membership of the Company and TLC Vision, and TLC Vision's disproportionately large share of funding of the Partnership to date, the Company has determined it is currently most appropriate to account for the investment in the Partnership on the equity method for U.S. GAAP purposes. Variable Interest Entity Given the small amount of equity investment at risk by the Company and TLC Vision, the Partnership meets the following definition of a VIE: "...the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support from other parties". The Partnership does not have sufficient funding from TLC Vision and the Company to finance its activities and continues to be financed by the equity holders and by TLC Vision, which has provided the funding through RHEO - 60 - Clinic Inc. for the Partnership to pay the Company for treatment sets and pumps purchased by the Partnership. TLC Vision currently funds the Company at a rate of $175,000 per month in accordance with the terms of the TLC Vision secured convertible grid debenture. The convertible grid debenture funding is intended to be applied towards the completion of the MIRA-1 clinical trial. It is expected that funding of purchases of RHEO System products from suppliers for the Partnership will be funded by either the Partnership (i.e., through advances from the equityholders, TLC Vision and the Company) or their customers, of which RHEO Clinic Inc., a subsidiary of TLC Vision, is the largest. The Partnership does not have a significant amount of cash to fund operations, and will continue to require funding from the equityholders or their subsidiaries. Given these circumstances, it is clear that the investment in the Partnership is not sufficient to finance its activities without additional financial support. The Company's investment in the Partnership is not considered an exception as per Paragraph 4 of FIN 46(R). Determination of Primary Beneficiary of the VIE FIN 46 (R) Paragraph 17 states that, "if two or more related parties hold variable interests in the same variable interest - 61 - entity, and the aggregate variable interest held by those parties would, if held by a single party, identify that party as the primary beneficiary, then the party, within the related group, that is most closely associated with the VIE is the primary beneficiary. The determination of which party...is most closely associated with the VIE requires judgment and shall be based on an analysis of all relevant facts and circumstances." The above paragraph applies to the Partnership, as the aggregate of TLC Vision and the Company's investment in the Partnership is a 100% interest. The facts and circumstances regarding TLC Vision and the Company's association with the Partnership are as follows: (a) the existence of a principal-agency relationship between parties within the related party group. There does not appear to be a principal-agency relationship between TLC Vision and the Company, as neither of these two companies are acting on behalf of the other with respect to the activities carried out by the Partnership, and (b) the relationship and significance of the activities of the VIE to the parties in the related party group. - 62 - Each of TLC Vision and the Company have differing roles with respect to the activities of the Partnership. The Company has acquired the rights to market and distribute the technology which it has, in turn, licensed to the Partnership. It has licensed software (the Company had created software which captured clinical data from the RTC treatment site in Florida), patents, trademarks and know-how to the Partnership, and has appointed the Partnership its sales representative for the RHEO System for which the Company has distribution and marketing rights. Although the appointment of the Partnership as sales representative for the Company suggests that the Partnership's activity is significant, the joint venture is structured such that the Company does not make a profit on sales to the Partnership, but rather that profits from the sale of the RHEO System are realized by the Partnership and shared between the equity investors. TLC Vision has licensed software (TLC Vision has created proprietary contact management and outcome analysis software called Pharos, for which it has created a subset applicable to the capture of Rheopheresis activities) to the Partnership, and its subsidiary, the RHEO Clinic Inc., provides many administrative and support activities for the Partnership (including but not limited to the rental of office space, storage of - 63 - Partnership inventory, and assistance with inventory management when necessary). Also, much of the management of the Partnership consists of TLC Vision executives who became involved with the Company and the Partnership as TLC Vision made its investments in the Company and ultimately the Partnership. The Chairman of TLC Vision is also the Chairman of the Partnership and the Company and the control of the Company's board prior to this offering rested with TLC Vision and Diamed, with TLC Vision taking the management role. The senior financial person for the Company and Partnership was TLC Vision's former controller. (c) A party's exposure to the expected losses of the VIE. The structure is such that both TLC Vision and the Company have a 50% interest in the Partnership. However, TLC Vision and its subsidiary's funding of the Partnership is disproportionately large compared to that of the Company (e.g., balances due to RHEO Clinic Inc., a TLC Vision subsidiary are $240,000 at March 31, 2004 or $202,000 at December 2003 while balances due to the Company were $31,000 at March 31, 2004 or $15,000 at December 31, 2003). TLC Vision funds the Partnership in two ways. First, through RHEO Clinic Inc. it has provided the necessary - 64 - funding for the Partnership to pay for product purchased from the Company. Due to the Partnership's ordering greater amounts of inventory than its customers, including RHEO Clinic Inc., have purchased, it was necessary for RHEO Clinic Inc. to pay for the Partnership's purchases as the Partnership did not have the required funds and the Company's funding from TLC Vision is to be used for clinical trial activities and not to assist in commercial activities through the Partnership. Second, where there are costs for salaries, office supplies and similar items in which the TLC Vision payroll or A/P process was used TLC Vision allows these balances to go unpaid due to lack of funds within the Partnership and due to significant delays in being able to open bank accounts for the Partnership. Also, TLC Vision has the greater exposure to expected losses of the Partnership as a result of its indirect investment in the Partnership through its shareholdings in the Company. TLC Vision owns 50% of the Partnership plus 26% of the Company for a combined (direct and indirect) ownership of around 62%-63%. In connection with this offering, the activities of the Partnership will be merged back into the Company. Although this might suggest that the Company is more closely associated with or has greater exposure to the losses of the Partnership, the transaction is structured such that TLC Vision will receive shares of the - 65 - Company such that its proportionate interest in the Partnership will be maintained, giving TLC Vision total ownership of 62 to 63% in the new entity which will result from the reorganization of the Company and the Partnership. As a result, TLC Vision maintains the larger exposure to the losses from the activities of the Partnership. (d) The design of the VIE. The Partnership was designed by TLC Vision's counsel with the primary goal of optimizing TLC Vision's ability to utilize tax losses. The effect of the joint venture structure on the Company was a secondary concern. Based on these factors, the Company determined that OccuLogix, Inc. was not the primary beneficiary of the Partnership; therefore the Company has accounted for its investment in the joint venture as an equity investment. 96. WE NOTE YOU AGREED TO CONVERT $500,000 OF THE ASAHI MEDICAL NOTE INTO SHARES OF COMMON STOCK AT A PRICE OF $0.98502 PER SHARE IN NOVEMBER 2003. SUPPLEMENTALLY PROVIDE US WITH THE ANALYSIS YOU PERFORMED IN CONCLUDING THAT A BENEFICIAL CONVERSION FEATURE DID NOT ARISE FROM THIS AGREEMENT. - 66 - OTHERWISE, REVISE THE FINANCIAL STATEMENTS TO REFLECT AND ACCOUNT FOR THE BENEFICIAL CONVERSION FEATURE. REFER TO EITF98-5 AND 00-27. In response to the Staff's comment, the Company provides the following supplemental analysis. EITF 98-5 paragraph 1 states a beneficial conversion feature to be the following: "Those securities may be convertible into common stock at the lower of a conversion rate fixed at the commitment date or a fixed discount to the market price of the common stock at the date of conversion." The Company's equity instruments are not freely traded and therefore obtaining market price is difficult in the absence of a financing transaction. The most recent financing transaction occurred on June 25, 2003 when TLC Vision and Diamed agreed to invest up to $12,000,000 in funding (convertible and non-convertible) at a conversion price of $0.98502 per share. A portion of the Asahi Medical Note was converted into shares of common stock in November 2003 at a price of $0.98502 per share. The conversion price was negotiated between Asahi and the Company. The Company believed this amount - 67 - to be market value at such date based on the TLC Vision and Diamed funding that occurred on June 25, 2003, which was a relatively proximate transaction. Furthermore, negotiations with Asahi were ongoing during this time period. Lastly, the Company did not experience any significant changes in its operations, including but not limited to its efforts related to clinical and regulatory activities, during the period from June 2003 to November 2003. The implied value of the Company's pending initial public offering was not considered in determining whether the Asahi Medical Note had a beneficial conversion feature. The Company applied the implied value of the initial public offering to only those options granted to senior management and the Board of Directors as these individuals were considered to be insiders of the Company. 97. IN THIS REGARD, PROVIDE US WITH A SIMILAR ANALYSIS ADDRESSING EACH OF THE CONVERSIONS OR AGREEMENTS TO CONVERT DISCUSSED IN NOTE 13. EXPLAIN CLEARLY HOW YOU DETERMINED THE FAIR VALUE OF YOUR COMMON STOCK AT THE DATE OF EACH ASSESSMENT. - 68 - In response to the Staff's comment, the Company supplementally advises that it determined the fair value of its common stock with respect to each of the items in Note 13 as follows: 13(a) Authorized share capital: No analysis is required. 13(b) Reorganization and reverse stock split: No analysis is required. 13(c) Share conversion: The valuation of the share conversion referred to in Note 13(c) is explained in the Company's response to Staff comment number 96 above. 13(d)(i) Series A convertible preferred shares: As identified in Note 7(i) of the financial statements, the Company issued convertible series B debentures in the 1999, 2000 and 2001 fiscal years. These debentures were convertible into preferred shares of the Company at a price of $2.00 per preferred share. Attached to these debentures were warrants to purchase preferred shares, also at a price of $2.00 per share. A review of the prior financing of the Company reflected the fact that in 1997 Series A preferred shares were issued at $2.00 per share and in 1998 common shares were issued at $1.00 per share. As such the pricing of the convertible - 69 - series B debentures has not provided any benefit to the investors. The 4:1 compression of all equity in July 2002 resulted in the $2.00 value being adjusted to $8.00. The anti-dilution impact (as per original terms of the debenture) of the initial funding from TLC Vision in 2002 resulted in anti-dilution calculations which reduced the conversion prices of the debentures as previously agreed upon and did not provide any benefit in the conversion process. 13(d)(ii) Series B convertible preferred stock: As identified in Note 7(ii) of the financial statements, the Company issued subordinated convertible promissory notes in April 2002 at a conversion price of $5.78 subsequent to 4:1 compression and anti-dilution calculations. The conversion features of these instruments were set out in the applicable legal documentation and represented a price negotiated with an independent third party (i.e., TLC Vision, which had not previously invested in the Company). In July 2002, these notes were converted as per the terms set out. No benefit occurred in the conversion process. As identified in Note 7(ii) of the financial statements, the Company issued Series B convertible debentures in May 2002 at a conversion price of $5.20 subsequent to 4:1 compression and anti-dilution calculations. This conversion price represented a discount to the April 2002 financing and represented negotiations with third parties to ensure sufficient funds were in place for the Company to - 70 - remain in business until additional financing was obtained in July 2002. The conversion features of these debentures were set out in the issuance documents of the debentures and were not deviated from. The conversion process for these debentures does not represent a beneficial conversion feature. No other equity instruments were issued as a result of the conversion of debt instruments. The Company has been consistent in following the conversion terms as originally defined in those debentures which have been converted and in the exceptional instance in which $500,000 of the Asahi Medical Note was converted without having had conversion terms previously defined, Management believes it used fair value as negotiated with Asahi (consistent with the June 2003 financing) for that conversion.

Previously all budgets included only completion of the FDA trial by the end of 2006. The Company uses SFAS 123 for all non-employee/ director options. It uses APB25 for employee/director options. As a result of SEC guidance, it was believed that the value of the IPO would be ascribed to the December 2003 options and as such these options were accounted for based on the intrinsic value (APB25) between the strike price and the IPO price using the Company's best estimate of value for the Company at the date of the initial filing of the Form S-1 of $500 million. Prior to the current year, there was no progression in value of the common stock. In January to February 2004, enrollment in MIRA-1 increased. As a result of this information, analysts who follow TLC Vision began to ascribe increasing value to its investment in OccuLogix in their reports on TLC Vision. Management's first discussions with the underwriters occurred in March 2004. In establishing the - 75 - strike price of the December 2003 options, the Company acted on its belief that the value of $0.99 was the best indication of value at that time. EXHIBITS 103.
