--------------------------------------------------------------------------------

In connection with the recent merger between TLC and LaserVision, individuals
holding outstanding TLC stock options, previously granted at an option price
higher than US$8.688, will be given the opportunity to exchange their options
for new options with an option price of US$8.688.

There are many important details regarding this voluntary offer contained in the
Offer to Exchange and other related documents that accompany this letter, and
you are urged to read these materials thoroughly. However, some key elements of
the offer are worth highlighting:

o     Only those options with an option price greater than US$8.688 are affected
      by this offer. Any outstanding options with an option price at or below
      US$8.688 will not be affected.

o     Optionholders who elect to participate in the offer will have their old
      options cancelled and new options issued to them.

o     For eligible options with an option price of over US$40, we will grant one
      new option for every four eligible options cancelled in the offer.

o     For eligible options with an option price of at least US$30 but less than
      US$40, we will grant one new option for every three eligible options
      cancelled in the offer.

o     For eligible options with an option price of at least US$20 but less than
      US$30, we will grant one new option for every two eligible options
      cancelled in the offer.

o     For eligible options with an option price of greater than US$8.688 but
      less than US$20, we will grant one new option for each eligible option
      cancelled in the offer.

o     The terms and conditions of the new options will be substantially similar
      to the terms and conditions of your options that are tendered and
      cancelled.

                                     - 2 -


o     If you are eligible and decide to tender any of your eligible options for
      cancellation, you must tender all of such options. Of course, the decision
      to participate is your own. TLC makes no recommendation as to whether you
      should participate in this offer.

Please review the enclosed Offer to Exchange for additional information. You
will also find enclosed a personalized statement summarizing all of your
outstanding options and how many options you will hold if you elect to
participate in the offer. We have also enclosed a Stock Option Q&A and Glossary
of Terms for your reference.

If you decide to tender your eligible options for exchange under this offer, you
must properly complete and submit the signature page to the enclosed acceptance
letter NO LATER THAN 11:59 P.M. eastern daylight savings time, on September 6,
2002, by regular external mail, interoffice mail or facsimile. E-MAIL DELIVERY
