From the beginning, VISX's success has been based upon unparalleled Research and Development efforts in the field of Laser Vision Correction technology. Today these efforts are represented by the marriage of the STAR S4 Excimer Laser System and the WaveScan® Wavefront System creating the CustomVue® procedure.
The CustomVue® procedure tailors a distinct correction for each individual – in fact each treatment is “designed” by the unique characteristics of the individuals’ eyes. WaveScan® technology captures unique imperfections in each individual’s vision that could not have been measured before. This new level of measurement provides 25-times more precision than measurements using standard methods for glasses and contact lenses. WaveScan® technology produces a detailed map of the eye – much like a fingerprint, no two are alike and translates this information into a set of CustomVue® treatment instructions for the laser. WaveScan® transfers these digital treatment instructions to the laser, providing a new level of precision and accuracy.
Beyond Glasses and Contacts
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. This precise level of measurement and treatment can enable individuals to achieve the full potential of their vision.
Clinical Study Results
VISX's FDA clinical study results were remarkable. Among other things:
At one year after the VISX CustomVue® procedure*
100% of the clinical study participants could pass a driving test without glasses or contacts
98% of the clinical study participants could see 20/20 or better without glasses or contacts
70% of the clinical study participants could see 20/16 or better without glasses or contacts
Four times as many clinical study participants were very satisfied with their night vision after the VISX CustomVue® procedure, compared to their night vision before with glasses or contacts.
WaveScan® Wavefront System
The WaveScan® WaveFront System is an ophthalmic diagnostic instrument that measures the refractive error and wavefront aberrations of the human eye using a Hartmann-Shack wavefront sensor. The measurements can be used to determine regular refractive errors ( myopia, hyperopia, astigmatism) and irregularities (aberrations) that cause decreased or blurry vision in the human eye. The WaveScan® software uses the information to create a custom tailored correction map for the unique characteristics of each individual eye.
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. The powerful WaveScan software translates the information into a set of CustomVue® treatment instructions for the laser. These digital treatment instructions are then 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 is not uniquely tailored to your fingerprint of vision. Now, with WaveScan® technology, Dr. Gualtieri can custom tailor a correction for the unique characteristics of your vision.
Will I Benefit From a WaveScan and CustomeVue?
Initially you will meet with Dr. Gualtieri for a complete medical evaluation and eye history to determine whether you are a good candidate for the LASIK procedure. He will discuss the benefits and risks of the procedure with you. A WaveScan® measurement will be taken to map the unique characteristics of your eye. With this map, Dr. Gualtieri will be able to accurately assess whether you're a good candidate for CustomVue® 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 Dr. Gualtieri performs, an individualized treatment plan can then be developed to address your unique vision needs.
