Exhibit 99.1

                      VISX Operating Profit Up 89 Percent

     SANTA CLARA, Calif.--(BUSINESS WIRE)--Oct. 21, 2004--VISX, Incorporated
(NYSE:EYE) today announced financial results for the third quarter and nine
months ended September 30, 2004.
     Third quarter revenues were $38.7 million compared with $39.3 million for
the comparable period of 2003. Operating income increased 89 percent, due to a
favorable product mix shift to higher margin license revenue in the quarter. Net
income rose to $0.22 per diluted share from $0.10 in last year's third quarter,
reflecting higher operating income as well as an effective tax rate of 24.5
percent.
     License revenue, which generated a 97 percent gross margin, grew 16 percent
from the comparable period of 2003. This increase resulted from 4 percent growth
in U.S. procedure volume compared to the third quarter of last year, as well as
higher CustomVue procedure sales in both domestic and international markets.
     "Our highly profitable license revenue drove operating profit sharply
higher this quarter," stated Liz Davila, VISX chairman and CEO. "In the eastern
United States, in particular in the southeast where business was repeatedly
disrupted by the impacts of the hurricanes, we experienced weaker than
anticipated procedure volume. However, in the rest of the country, we saw
healthy procedure volume growth of 8 percent. In the international market,
CustomVue procedures were three times last year's level."
     Davila continued, "In the U.S., we are awaiting approval of our CustomVue
hyperopia procedure which will expand our market opportunity for CustomVue. Our
total CustomVue conversion in the quarter was just over 35 percent. More than
200 U.S. accounts are now at 50% or greater conversion to CustomVue. We are
expanding our marketing and training programs to target the low volume accounts
that are lagging behind the average."
     VISX results for the third quarter of 2004 included tax-related items that
increased earnings per diluted share by approximately $0.04.
     VISX cash and equivalents at the end of the third quarter were $121.0
million. Cash flow from operations was $6.2 million reflecting higher net income
offset by increased inventory for anticipated laser and new product shipments
and higher receivables.
     Revenues for the nine months ended September 30, 2004, increased to $125.5
million compared with $105.7 million for the comparable period of the prior
year. Net income more than doubled to $32.6 million, or $0.64 per diluted share,
in the first nine months of 2004 compared with net income of $14.4 million, or
$0.28 per diluted share, in the first nine months of 2003.

     Financial Outlook:

     VISX believes that fourth quarter revenues will be in the range of $39 to
$42 million. EPS is expected to be in the range of $0.17 to $0.20 for the
quarter. The tax rate in the fourth quarter is anticipated to be 40 percent.
     For 2004, the Company expects revenue growth of 14 percent to 16 percent
compared to 2003 and earnings per diluted share of $0.81 to $0.84, an increase
of over 75 percent compared with last year's earnings per diluted share.
     VISX is targeting 25 percent to 30 percent operating profit growth in 2005.

     New Product Introductions:

     CustomVue Presbyopia

     In the third quarter, VISX launched internationally its CustomVue
presbyopia treatment for far sighted individuals that require reading glasses.
This is the first commercially available laser treatment of presbyopia that
corrects the eye for simultaneous near and distance vision.

     Fourier Wavefront Upgrade

     During the quarter, VISX introduced worldwide its Fourier Wavefront
Upgrade, a new software that fully utilizes the wavefront data to assess visual
error. This provides a new level of precision and unprecedented resolution for
individualized CustomVue treatments.

     Iris Registration

     In international markets, VISX introduced its Iris registration product. It
is the first fully automated method of adjusting for the differences between the
eye's position when sitting for a WaveScan measurement versus lying down for the
laser treatment.

     About CustomVue Laser Vision Correction:

     CustomVue laser vision correction employs a diagnostic laser system that
analyzes the optical errors in the eye. Much like a fingerprint, each person's
visual error is unique and can now be captured through the use of the VISX
WaveScan System. The information is digitally recorded, transferred to the VISX
STAR Laser System and the CustomVue laser vision correction procedure is
customized based on the specific refractive errors of the individual. With the
new CustomVue product, ophthalmologists can correct aberrations, or
imperfections, of the eye that previously were not measured. This means that
custom technology has the potential to improve vision beyond correction with
contacts and glasses.

     Conference Call:

     VISX management will discuss its third quarter financial results on a
conference call at 4:30 p.m. eastern time on October 21, 2004. The call will be
Webcast live at www.visx.com and will be available for a period of one week
following the call. A telephone rebroadcast of the call will also be available
for one week following the conclusion of the call. To access the rebroadcast via
telephone, call 888-286-8010. International callers should call 617-801-6888.
Enter reservation number 30387865.

     This press release contains certain forward-looking statements based on
current expectations, forecasts, and assumptions of VISX that involve risks and
uncertainties. Forward-looking statements in this release, including statements
that our CustomVue hyperopia procedure will expand our market opportunity for
CustomVue, that we plan to expand our marketing and training programs to target
the low volume accounts that are lagging behind the average in CustomVue

profit growth in 2005 of 25 percent to 30 percent, are based on information
available to the Company as of the date hereof. The Company's actual results
could differ materially from those stated or implied in such forward-looking
statements, due to risks and uncertainties associated with the Company's
business, which include the fact that market acceptance of our products, and
particularly of CustomVue, is uncertain and depends on broad acceptance by
physicians and patients, that intense competition in the laser vision correction
industry could result in the loss of customers, an inability to attract new
customers, or a decrease in prices for our products, that we face risks due to
our reliance on sales in international markets, that we are subject to extensive
governmental regulation, which increases our costs and could prevent us from
selling our products, that the possibility of long-term side effects and adverse
publicity regarding laser correction surgery could seriously harm our business,
that we have and may become subject to product liability claims, that adverse
economic conditions may cause our revenues to decline, and that expenses are
relatively fixed in the short term and declines in revenue would have an
immediate impact on earnings per share. Further information on risk factors is
contained in the Company's most recent filings with the Securities and Exchange
Commission, including VISX's Annual Report on Form 10K for the year ended
December 31, 2003 and VISX Form 10-Q for the quarter ended June 30, 2004. The
Company assumes no obligation to update the information included in this press
release, whether as a result of new information, future events, or otherwise.
