To Participants in the TLC Vision Corporation 2004 Employee Share Purchase Plan and 1997 Share Purchase Plan for Canadian Employees:

Enclosed for your consideration is an offer to purchase, dated May 11, 2007, in connection with a tender offer being conducted by TLC Vision Corporation. TLC is offering to purchase for cash up to 20,000,000 of its common shares from its shareholders. The tender offer will be conducted upon the terms and subject to the conditions set forth in the Offer to Purchase. TLC is inviting shareholders to tender shares at a price between US$5.75 and US$6.25 per share (the “purchase price”), without interest, upon the terms and subject to the conditions of the tender offer.

The TLC Vision Corporation 2004 Employee Share Purchase Plan and 1997 Share Purchase Plan for Canadian Employees (collectively, the “Plan”) hold TLC common shares on behalf of participants in the Plan. The custodian of the Plan, The Bank of New York, is the owner of record of all TLC common shares held by the Plan. As such, the Plan custodian is the only one who can tender shares held by the Plan. The Plan custodian will tender shares held by the Plan only if and to the extent it is directed by Plan participants.

Participants in the Plan who hold TLC common shares in their Plan accounts may participate in the tender offer by giving directions to the Plan custodian. To participate in the tender offer, you must direct the Plan custodian by completing and returning the attached instruction form. You must complete this form by specifying the number of TLC common shares you hold in the Plan you wish to tender and the share price at which you wish to have the TLC common shares purchased. If you select a Purchase Price Tender or you fail to specify a purchase price, you will be deemed to have selected a purchase price of US$5.75.

TO PARTICIPATE IN THE TENDER OFFER YOU MUST COMPLETE THIS FORM AND IT MUST BE RECEIVED BY THE BANK OF NEW YORK AT THE ADDRESS LISTED BELOW BY 5:00 P.M., EASTERN TIME, ON JUNE 20, 2007.

The purchase of shares by TLC is subject to proration if the number of common shares properly tendered and not withdrawn by shareholders exceeds 20 million shares. In such an event, common shares tendered by the Plan custodian but not purchased will be returned to your account.

Please complete and return this form to instruct the Plan custodian as to whether you wish the custodian to tender any or all of the TLC common shares you hold in the Plan on the terms and subject to the conditions of the tender offer and at what price you wish to tender these shares.

We call your attention to the following:

1.	The purchase price is between US$5.75 and US$6.25 per share at your selection at US$0.05 intervals, net to you in cash, without interest.
2.	The tender offer is not conditioned upon any minimum number of shares being tendered. The tender offer is, however, subject to certain other conditions set forth in Section 4 of the offer to purchase.
3.	The Bank of New York must receive this form by 5:00 p.m., Eastern time, on June 20, 2007, if you wish to participate in the tender offer.
4.	The tender offer is for up to 20,000,000 shares, constituting approximately 29% of TLC’s shares outstanding as of May 4, 2007.
5.	The board of directors of TLC has approved the tender offer. However, neither TLC nor its board of directors makes any recommendation to shareholders as to whether to tender or refrain from tendering their shares.

Shareholders must make their own decision as to whether to tender their shares and, if so, how many shares to tender.

If you wish to have the Plan custodian tender any or all of the TLC common shares you hold in the Plan, please so instruct by completing, executing, detaching and returning to us the attached instruction form.

The tender offer is being made solely under the offer to purchase and is being made to all record holders of shares. The tender offer is not being made to, nor will tenders be accepted from or on behalf of, holders of shares residing in any jurisdiction in which the making of the tender offer or acceptance thereof would not be in compliance with the securities, blue sky or other laws of such jurisdiction.
