      RECONCILIATION BETWEEN CANADIAN AND UNITED STATES GENERALLY ACCEPTED
      ACCOUNTING PRINCIPLES

      TLC Vision Corporation (the "Company") prepares its consolidated financial
      statements in accordance with United States (U.S.) Generally Accepted
      Accounting Principles ("GAAP"), which differ in certain respects from
      Canadian GAAP. This reconciliation between Canadian and U.S. GAAP should
      be read in conjunction with the consolidated interim financial statements
      as of June 30, 2005 and for the three and six months ended June 30, 2005
      and 2004 and related management's discussion and analysis prepared in
      accordance with U.S. GAAP and filed with the Securities Exchange
      Commission and the Ontario Securities Commission.

      a)    Reconciliation from U.S. GAAP to Canadian GAAP

            Following is a reconciliation of net income from U.S. GAAP to
            Canadian GAAP:

                                                                             =========      ============


(1)   During the year ended May 31, 2002, the Company reviewed its Practice
      Management Agreements ("PMA's") for impairment based on budgets prepared
      for future periods. The refractive industry had experienced reduced
      procedure volumes over the prior two years as a result of increased
      competition, customer confusion and a weakening North American economy.
      This reduction in procedures had occurred at practices the Company had
      purchased, and as a result revenues were lower than anticipated when
      initial purchase prices and resulting intangible values were determined.

      For U.S. GAAP purposes, the Company accounts for its intangible assets
      subject to amortization in accordance with Statement of Financial
      Accounting Standard ("SFAS") No. 142, "Goodwill and Other Intangible
      Assets" ("SFAS 142"). SFAS 142 requires the impairment analysis first
      consider undiscounted cash flows in determining if an impairment exists.
      If an impairment is evident, a second calculation using a discounted cash
      flow method is utilized to determine the actual amount of the impairment.
      For U.S. GAAP purposes, the Company recorded an impairment charge of $31.0
      million for the year ended May 31, 2002 related to its PMA's.

      For Canadian GAAP purposes, the Company measured the initial impairment
      charge in accordance with the Canadian Institute of Chartered Accountant's
      ("CICA") Handbook Section 3060, "Capital Assets", the Canadian GAAP rules
      in existence during the year ended May 31, 2002 ("CICA 3060"). CICA 3060
      required an impairment charge to be recognized when the expected future
      undiscounted cash flows exceeds the carrying value of such assets.

                                       27


      As at May 31, 2002, this resulted in a $6.3 million difference in the
      write-down of the PMA's between U.S. and Canadian GAAP ($24.7 million).
      This difference in the initial measurement of the impairment further
      resulted in a difference to the amortization expense in subsequent
      periods, resulting in an additional $4.7 million of amortization expense
      for Canadian GAAP compared to U.S. GAAP.

      During 2003, the CICA issued CICA 3061, Property, Plant and Equipment
      which is consistent with U.S. GAAP, however retroactive adoption of this
      change was not required.

(2)   During the year ended May 31, 2002, the Company completed a sale-leaseback
      transaction. Total consideration received for the sale of the building and
      related land was $6.4 million, which was comprised of $5.4 million in cash
      and a $1.0 million 8.0% note receivable ("Note"). The Note has a
      seven-year term with the first of four annual payments of $63,000 starting
      on the third anniversary of the sale and a final payment of $0.7 million
      due on the seventh anniversary of the sale.

      For U.S. GAAP purposes, this transaction was accounted for in accordance
      with SFAS 98, "Accounting for Leases" ("SFAS 98"). SFAS 98 prohibits sale
      recognition on a sale-leaseback transaction when the sublease is
      considered to be minor and the only recourse to any future amounts owing
      from the other party is the leased asset. A sublease is considered to be
      minor when the present value of the sublease rent is less than 10% of the
      total fair market value. The Company accounted for the transaction as a
      financing transaction which requires sale proceeds to be recorded as a
      liability and for the Note to not be recognized. In addition, since the
      sale recognition is not accounted for, the carrying value of the asset is
      not adjusted for and the asset continues to be depreciated over the
      original depreciation period of 40 years. Lease payments, exclusive of an
      interest portion, decrease the liability while payments received on the
      Note increase the liability.

      For Canadian GAAP purposes, the sales-leaseback transaction was accounted
      for in accordance with Emerging Issues Committee No. 25, "Accounting for
      Sales with Leasebacks", which resulted in the Company recognizing a loss
      on the sale with a corresponding lease asset and lease obligation. The
      terms of the lease are considered capital in nature and accordingly the
      land and building are reflected as assets under capital lease with the
      discounted value of the lease payments recorded as an obligation under
      capital lease. The fair value of the assets under capital lease was less
      than its previous carrying value and accordingly a write down of
      approximately $0.8 million was reflected in the consolidated statement of
      operations for the year ended May 31, 2002.

      For U.S. GAAP purposes, depreciation expense reflects the higher net book
      value of the building depreciated over a 40-year expected life. For
      Canadian GAAP purposes, the building is depreciated over the 15-year life
      of the lease and the Note ($0.9 million as of June 30, 2005) is included
      in investments and other assets.

      As of June 30, 2005, as a result of the difference in the initial
      accounting treatment of the sale-leaseback transaction and subsequent
      differences in depreciation expense recorded, the net book value of the
      building is $1.9 million higher for U.S. GAAP. Investments and other
      assets is $0.9 million higher and notes payable is $0.7 million higher (of
      which $0.6 million is classified as long-term) for Canadian GAAP. For the
      three and six months ended June 30, 2005 and 2004, depreciation expense is
      higher for Canadian GAAP by $70,000 and $140,000, respectively.

(3)   For each of the three months ended June 30, 2005 and 2004, the Company
      reported $19,000 of interest income related to the Note on the
      sale-leaseback of the building as described above.

      For each of the six months ended June 30, 2005 and 2004, the Company
      reported $39,000 of interest income related to the Note on the
      sale-leaseback of the building as described above.

      As of June 30, 2005, $52,000 of interest income was not yet received, and
      the associated interest receivable was included in prepaids and other
      current assets for Canadian GAAP purposes. In the above U.S. GAAP to
      Canadian GAAP reconciliation, cumulative interest payments received of
      $231,000 are recorded as reductions to long-term debt in order to adjust
      the U.S. GAAP treatment of the payments, which increases the debt upon
      their receipt.

(4)   For U.S. GAAP purposes, the Company has adopted the disclosure
      requirements of SFAS No. 123, Accounting for Stock-Based Compensation
      ("SFAS 123") and as permitted under SFAS 123, applies Accounting
      Principles Board Opinion No. 25, Accounting for Stock Issued to Employees
      ("APB 25") and related interpretations in accounting for its

                                       28


      stock option plans. SFAS 123 requires disclosure of pro forma amounts to
      reflect the impact if the Company had elected to adopt the optional
      recognition provisions of SFAS 123 for its stock option plans and employee
      stock purchase plans.

      For Canadian GAAP purposes, the Company accounts for its stock options in
      accordance with the provisions of CICA Section 3870, Stock-Based
      Compensation and Other Stock-Based Payments, ("CICA 3870").

      CICA 3870, issued in December 2001, established standards for the
      recognition, measurement and disclosure of stock-based compensation, and
      other stock-based payments. Under the provisions of CICA 3870, prior to
      January 1, 2004, companies could either measure the compensation cost of
      equity instruments issued under employee compensation plans using a fair
      value-based method or could recognize compensation cost using another
      method, such as the intrinsic value-based method. However, if another
      method was applied, pro forma disclosure of net income or loss and
      earnings or loss per share was required in the financial statements as if
      the fair value-based method had been applied. Effective January 1, 2004,
      CICA 3870 requires that all stock-based compensation be measured and
      expensed using a fair value-based methodology.

      Prior to January 1, 2004, the Company recognized employee stock-based
      compensation under the intrinsic value-based method and provided pro forma
      disclosure of net income or loss and earnings or loss per share as if the
      fair value-based method had been applied. Effective January 1, 2004, the
      Company adopted the fair value-based method for recognizing employee
      stock-based compensation on a retroactive basis to January 1, 1996,
      without restatement of prior periods. At January 1, 2004, the cumulative
      effect of the change in accounting policy on prior periods resulted in a
      charge to accumulated deficit of $13.6 million which represents the sum of
      the previously disclosed pro forma fair value adjustments with a
      corresponding increase to contributed surplus.

      For the three months ended June 30, 2005 and 2004, the Company recorded
      stock-based compensation expenses of $1,361,000 (of which $591,000 relates
      to OccuLogix, Inc. stock options) and $278,000, respectively. For the six
      months ended June 30, 2005 and 2004, the Company recorded stock-based
      compensation expenses of $2,368,000 (of which $818,000 relates to

      The Company granted 45,000 and 30,500 stock options during the six months
      ended June 30, 2005 and 2004, respectively.

      OccuLogix, Inc. granted 1.5 million options during the six months ended
      June 30, 2005. The fair value of the options granted by OccuLogix, Inc.
      during the six months ended June 30, 2005 was estimated at the date of
      grant using the Black-Scholes option pricing model.

      During the year ended May 31, 2002, the Company allowed the holders of
      outstanding TLC Vision Corporation stock options with an exercise price
      greater than $8.688 (C$13.69) to elect to reduce the exercise price of
      their options to $8.688 (C$13.69), in some cases by surrendering existing
      options for a greater number of shares than the number of shares issuable
      on exercise of each repriced option. For U.S. GAAP purposes, such
      modification which results in a change in the exercise price of the
      underlying stock options is subject to APB 25's variable method of
      accounting for stock options. Variable accounting requires that
      differences between the price of the Company's common shares at the end of
      each reporting period and the modified exercise price be charged to income
      as compensation expense over the remaining vesting period of the
      outstanding options. For the three and six months ended June 30, 2004, the
      Company recognized additional stock compensation expense of $15,000 and
      $334,000, respectively, related to the modified stock options.

      During the six months ended June 30, 2005, OccuLogix, Inc. granted options
      that have vesting periods contingent upon the date at which OccuLogix,
      Inc. receives FDA approval for its RHEO(TM) System. These options are
      subject to APB 25's variable method of accounting for stock options.
      During the six months ended June 30, 2005, OccuLogix, Inc. recorded
      $12,000 of variable compensation expense related to these options (of
      which the Company recognized $6,000 after minority interests).

      CICA 3870 does not require the application of variable method of
      accounting for stock options.
