What is VISX CustomVue (individualized laser vision) correction?
VISX CustomVue individualized laser vision correction is a WaveScan®-driven procedure, which enables the physician to measure and correct unique imperfections in each individual’s vision. Many of these imperfections could never be measured before.
Who is a candidate for VISX CustomVue procedure?
Anyone 21 years of age or older who wears glasses or contacts to correct nearsightedness and/or astigmatism may benefit from CustomVue.
What is Personal Best Vision?
Because every individual’s eyes are unique, each individual would benefit from a correction custom-tailored for them. For the first time, CustomVue using WaveScan technology can measure and correct the unique characteristics of each individual’s vision, potentially providing them with the best possible vision for their eyes, or their Personal Best Vision.
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 measured before 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 the standard method. 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.
How is the information transferred from the WaveScan to the laser?
The WaveScan digital information is transferred to the laser, providing a new level of precision and accuracy.
What will a patient experience during the course of this procedure?
The individual will initially meet with our doctors for an evaluation to determine if he or she is a good candidate for the CustomVue procedure. A WaveScan measurement will be taken to map the unique characteristics of his or her vision. The physician will assess several criteria including level of correction and overall eye health. Once it is confirmed that they are a good candidate, he or she can be scheduled for CustomVue. The doctor will provide details for the individual on how to prepare for the day of the procedure.
On procedure day, the individual will be seated in a reclined position. Anesthetic drops will be placed in the eyes and a flap will be created on the cornea. The individual’s treatment information is transferred from the WaveScan to the laser to complete the CustomVue procedure. The actual laser procedure typically takes about a minute. Although some individuals feel a slight pressure sensation lasting a few seconds, the majority of individuals feel no pain during the procedure.
After treatment the vision will gradually improve over the first few days after surgery. You will be scheduled for a follow-up visit the next day, and again several weeks after the initial procedure.
Is VISX CustomVue™ better than glasses and contacts?
As shown in the FDA clinical study, VISX CustomVue can produce better vision than is possible with glasses and contact lenses. Glasses and contacts are limited in their ability to correct unique imperfections in each individual’s vision. In fact, thousands of individuals have the same prescription. With the CustomVue™ procedure, no two prescriptions are identical.
Will I need glasses or contacts after the CustomVue procedure?
Not likely. One year after the clinical study, all participants saw well enough to drive a car without glasses or contacts. Ninety-eight 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 one year after the VISX CustomVue™ procedure:
- 100% of participants could pass a driving test without glasses or contacts
- 98% of participants could see 20/20 or better without glasses or contacts
- 70% 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, one year after the CustomVue procedure more than 70% percent of clinical study participants saw 20/16 or better.
How could the CustomVue™ procedure affect my night vision?
Because CustomVue corrects the unique imperfections in each individual’s vision, it is likely that night vision will be improved. In fact, in the clinical study, four times as many participants were very satisfied with their night vision after the procedure as compared to their night vision before with glasses or contacts.
Why is WaveScan technology so important to the CustomVue procedure?
For the first time, WaveScan technology captures unique imperfections in each individual’s vision that could not have been measured before using standard methods for glasses and contact lenses. This new level of measurement provides 25-times more precision than standard measurements for glasses and contact lenses. Then, WaveScan technology produces a detailed map of the eye – much like a fingerprint, no two are alike. The WaveScan digital information is transferred to the laser, providing a new level of precision and accuracy.
