The Fingerprint of Your Vision™
Your vision is unique - as personal as your fingerprint or your DNA. WaveScan® technology provides your eye doctor with a map of your vision.
Initially you will meet with your eye doctor for a complete medical evaluation and eye history to determine whether you are a good candidate for the CustomVue procedure. Your doctor will discuss the benefits and risks of the procedure with you. A WaveScan measurement will be taken to map the unique characteristics of your vision. With this map, your doctor will be able to:]
- Accurately assess whether you're a good candidate for laser vision correction. Anyone who is considering laser vision correction should obtain a WaveScan measurement as the first step.
- Along with the other diagnostic tests that your doctor performs, an individualized treatment plan can then be developed to address your unique vision needs.
- Once it is confirmed that you are a good candidate, your doctor will schedule you for a CustomVue procedure. Your doctor will provide details to you on how to prepare for the day of the procedure.
If your doctor feels it is beneficial, he or she may choose to provide you with a PreVue Lens during the consultation. The PreVue Lens enables you to evaluate your potential vision before the CustomVue procedure. Your doctor will place a plastic lens under the laser. Using the information from the WaveScan, your unique correction will be placed on the lens. The lens is then fitted in a trial frame so that you can see your potential visual results. If a PreVue Lens is used in this evaluation, your vision through the PreVue lens is not meant to be predictive of the end result that you might achieve.
The CustomVue Procedure
On procedure day, you will be seated in a reclined position. Anesthetic drops will be placed in your eyes and a flap will be created on your cornea. Your individualized treatment information is transferred from the WaveScan to the laser in order to drive the CustomVue procedure. The actual laser procedure typically takes several seconds. The majority of individuals feel no pain during the procedure.
After CustomVue, you will notice results immediately, and your vision will continue to improve over the next few days. You will be scheduled for a follow-up visit the next day, and again several weeks after the initial procedure.
Please review the important information contained in the Patient Information Sheet.
Clinical Study Results
The U.S. Food and Drug Administration (FDA) has approved the VISX CustomVue™ procedure as a safe and effective method for correcting nearsightedness and astigmatism.
A significant visual acuity result of the FDA clinical study was that six months after the VISX CustomVue™ procedure:
- 100% of participants could see well enough to legally drive a car (20/40 or better) without glasses or contacts
- 94% of participants achieved uncorrected visual acuity of 20/20 or better
- 74% of participants were 20/16 or better
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.
Overall, many participants were more satisfied with their quality of vision after the VISX 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.
Uncorrected visual acuity is the measurement of how well you see without the aid of glasses or contact lenses.
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 your eyes 25 times more precisely than standard methods. In addition, WaveScan digital information 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.
