                                                                May 5, 2003

TO OUR STOCKHOLDERS:

With our Annual Meeting just weeks away, WE URGE YOU TO VOTE FOR THE VISX
BOARD OF DIRECTORS' NOMINEES BY SIGNING, DATING AND RETURNING TODAY THE
ENCLOSED GOLD PROXY CARD.

                           LEADERSHIP AND INNOVATION
                              DRIVE OUR BUSINESS

We are NUMBER ONE in our market. We GENERATE CASH from our business and we are
focused on building our business and providing continued value to you, our
stockholders. Our REVOLUTIONARY NEW PROCEDURE, CUSTOMVUETM, HAS THE POTENTIAL,
FOR THE FIRST TIME EVER, TO OFFER BETTER VISION THAN CONTACTS AND GLASSES.

                     VISX CONTINUES ITS STRONG PERFORMANCE

Our strong first quarter results show that we continue to drive profitability
and manage our business for our future growth. In the first quarter we:

         o    Achieved a solid 24% operating margin

         o    Grew our licensing revenue by 20% from the previous quarter - an
              extraordinary performance under current weak economic conditions

         o    Shipped 107 WaveScan Systems - our strongest quarter yet, and

         o    Reported Q1 earnings per share of $0.11, surpassing
              expectations.

                           CARL ICAHN IS AT IT AGAIN

Yes, Carl Icahn is at it again. He has nominated Keith Meister to our board.
This follows the Icahn group's:

      o  2001 proxy challenge, during which the Icahn group offered to
         purchase VISX, but later abandoned his effort,

      o  2002 challenge, where the Icahn group stated an intention to nominate
         a slate of directors, which was also abandoned.

This year's candidate, KEITH MEISTER, IS A 30 YEAR-OLD ICAHN EMPLOYEE WHO WE
BELIEVE LACKS ANY RELEVANT EXPERIENCE THAT MIGHT HELP THE COMPANY CAPITALIZE
ON ITS EXCITING GROWTH OPPORTUNITIES. In fact, we believe he was nominated to
pursue Mr. Icahn's personal agenda.

               ICAHN'S EMPLOYEE BRINGS NOTHING TO THE VISX BOARD

We believe Mr. Meister lacks the qualifications appropriate to serve on our
board. Prior to his current position with Mr. Icahn, Mr. Meister managed a
fund at J Net Enterprises, formerly Jackpot Enterprises. According to the J
Net's SEC filings:

         o    Meister's employment was terminated

         o    The company has since been delisted.

Mr. Meister's experience as a public company director appears to be limited to
just four months with a company controlled by Mr. Icahn.

Our current board is firmly committed to upholding its responsibility to you
to operate VISX in a manner that is in your best interest. To that end, we do
not believe that Mr. Meister has the industry knowledge or business experience
to adequately represent your interests as a board member of VISX.

           VISX HAS THE RIGHT TEAM IN PLACE TO GROW THE COMPANY AND
               CREATE LONG-TERM VALUE FOR ALL OUR STOCKHOLDERS

OUR BOARD IS COMPRISED OF SEASONED LEADERS WITH DECADES OF EXPERIENCE, who
have:

         o    Spent years as decision makers in the medical industry

         o    Held senior level executive positions in NYSE or NASDAQ listed
              companies

         o    Participated in decisions to buy and sell companies, and

         o    Served as independent directors of other public companies.

                            YOUR VOTE IS IMPORTANT

WE BELIEVE THAT YOUR VOTE FOR THE VISX BOARD OF DIRECTORS' NOMINEES WILL
ENSURE THAT YOU ARE VOTING FOR AN EXPERIENCED BOARD THAT CONSIDERS THE
INTERESTS OF ALL STOCKHOLDERS. Your Board of Directors unanimously recommends
that VISX stockholders vote the enclosed GOLD PROXY CARD today FOR your
Board's director nominees and DISCARD ANY PROXY CARD THAT YOU MAY RECEIVE FROM
MR. ICAHN AND HIS AFFILIATES.

On behalf of your Board of Directors, I thank you for your continued
confidence and support.

                                  Sincerely,


                                  Elizabeth Davila
                                  Chairman, President, and CEO
