What is VISX CustomVue™ (individualized laser vision) correction?
VISX CustomVue individualized laser vision correction is WaveScan®-driven, which enables the physician to measure and correct unique imperfections in each individual's vision. Many of these imperfections could never be measured before using standard methods for glasses and contact lenses.

Who is a candidate for the VISX CustomVue procedure?
If you are 21 years of age or older and wear glasses or contacts to correct nearsightedness and/or astigmatism, you may benefit from CustomVue™. If you meet the criteria, you should see your eye doctor for more information.

What is WaveScan® technology?
WaveScan technology was originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space. This technology has now been applied to laser vision correction, measuring imperfections in the eye never before measured using standard methods for glasses and contact lenses. WaveScan-based digital technology identifies and measures imperfections in an individual's eye 25 times more precisely than standard methods. Physicians use this information to treat individuals with the CustomVue procedure.

Why is WaveScan technology so important to the CustomVue procedure?
Until now, physicians were forced to practice one-size-fits-all vision. An off-the-shelf lens corrects an individual's vision fairly well, but it does not correct it precisely because it is not uniquely tailored to that person's fingerprint of vision. Now, with WaveScan technology, we can custom tailor a correction for the unique characteristics of each individual's vision.

Will I need glasses or contacts after the CustomVue procedure?
Probably not. Six months after the FDA clinical study, all participants saw well enough to drive a car without glasses or contacts. Ninety-four percent had 20/20 vision. However, individual results may vary.

What were the visual acuity results of the FDA clinical study?
A significant result was that six months after the VISX CustomVue™ procedure:

      • 100% of participants could pass a driving test
         without glasses or contacts
      • 94% of participants could see 20/20 or better
         without glasses or contacts
      • 74% of participants could see better than 20/20
         without glasses or contacts

What does "better than 20/20" mean?
20/20 is the current standard for excellence in vision. But, with the CustomVue procedure, individuals have the potential to see even better than 20/20. In fact, six months after the CustomVue procedure more than 74% percent of clinical study participants saw 20/16 or better.

How could the CustomVue procedure affect my night vision?
In the clinical study, many participants found their night vision was improved after the CustomVue procedure. In fact, four times as many participants were very satisfied with their night vision after the procedure, as compared with their night vision before with glasses or contacts.
