Q. Who is a candidate for the VISX CustomVUE™ procedure?
A. 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™.

Q. What is WaveScan® technology?
A. WaveScan technology was originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space. The 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.

Q. Why is WaveScan® technology so important to the CustomVue™ procedure?
A. Until now, physicians were forced to practice one-size-fits-all vision correction. An off-the-shelf lens corrects and 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® we are able to measure more precisely the subtle changes on an individuals cornea.

Q. Will I need glasses or contacts after the CustomVue™ procedure?
A. 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 hand 20/20 vision. However, individual results may vary.

Q. What were the visual acuity results of the FDA clinical study?
A. 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.

Q. What does “better than 20/20” mean?
A. 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 procedure more than 74% of clinical study participants saw 20/16 or better.

Q. How could the CustomVue™ procedure affect my night vision?
A. 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.

Q. What is the PreVue™ Lens?
A. The PreVue™ Lens allows individuals to test drive their potential new vision before undergoing the procedure. Once the WaveScan measurement is taken, the physician places a plastic lens under the VISX laser. The individual's unique correction is placed on the lens, and then the lens is fitted in a trial frame for viewing. The PreVue lens is not a requirement for the CustomVue™ procedure. Your physician will decide if this tool is beneficial for you. If a PreVue lens is used in this evaluation, your vision through the PreVue lens is not meant to be predictive of the results that you might achieve.
