Wavefront Driven Refractive Laser Vision Correction.

Your vision is unique — as personal as your fingerprint or your DNA. Visx CustomVue wavescan laser  vision correction sets a new standard for visual quality and results to correct the unique imperfections in your vision.

In the clinical study leading to FDA approval, many participants were more satisfied with their quality of vision after the CustomVue procedure than before the procedure with use of glasses or contacts. Quality of vision refers to not only what you see, but also how well you see under a variety of conditions, such as driving at night.

Four times as many participants were very satisfied with their night vision after CustomVue, compared to their night vision with their glasses or contact lenses before the procedure.

CustomVue uses WaveScan® technology, which provides your eye doctor with a map of your vision.

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 measured before using standard methods for glasses and contact lenses.

WaveScan-based digital technology identifies and measures imperfections in your eyes 25 times more precisely than standard methods. In addition, WaveScan provides information that is transferred to the laser, driving a new level of precision and accuracy.

Until now, eye doctors were forced to practice one-size-fits-all vision. An off-the-shelf lens can correct your vision fairly well, but it does not correct it precisely. Now, with WaveScan technology, your eye doctor can custom tailor a correction for the unique characteristics of your vision.

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.

What is the PreVue® Lens?
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 result that you might achieve.
