What is CustomVue laser vision correction?

Visx CustomVue is an individualized laser vision correction treatment that is WaveScan-guided. This enables a doctor to measure and correct unique imperfections in each individual's vision that could never be measured before with standard methods used for glasses and contact lenses. With the CustomVue procedure, individuals have the potential to achieve a new level of vision that we call Personal Best Vision.

Does the WaveScan hurt?

No, the WaveScan is a measurement device that you simply gaze into while it measures the vision imperfections in your eye.

What do you mean by Personal Best Vision?

Personal Best Vision refers to the new level of laser vision correction that can be achieved with the CustomVue procedure. Since WaveScan technology can measure and correct imperfections that are unique to each individual's vision with 25 times more precision than standard measurements for glasses and contact lenses, individuals can potentially achieve the best possible vision for their eyes.

How accurate is WaveScan technology?

WaveScan technology identifies and measures imperfections in an individual's vision 25 times more precisely than standard methods used for glasses and contact lenses.

How does the CustomVue procedure work?

First, the WaveScan technology measures the imperfections in the eyes and produces a WavePrint Map. Much like a fingerprint, no two WavePrint maps are alike. Then, the treatment information is transferred to the Visx Star S4 laser. The doctor then uses that information to fine-tune the procedure thereby providing a new level of precision and accuracy.

What can CustomVue procedure do for me?

As shown in the clinical study, CustomVue has the potential to produce better vision than is possible with glasses and contact lenses. It tailors a distinct correction for each individual - in fact each treatment is "designed" by the unique characteristics of your individual eye.

Can the CustomVue procedure improve my night vision?

Yes, potentially. In the clinical study, four times as many people were very satisfied with their vision at night after the procedure as compared to their night vision before the procedure with glasses and contact lenses.

What is WaveScan and a WavePrint Map?

WaveScan technology provides a measurement and a visual representation of your vision based on the behavior of light waves. It compares light passing through your eye to the same light pattern from an eye that needs no vision correction. The WavePrint Map is the output of the WaveScan, it captures the unique imperfections of a person's visual path.

How WaveScan WaveFront Works

WaveScan WaveFront technology was originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space. Using this technology, your doctor can detect and measure the optical distortions unique to your entire optical system.

Light travels in a procession of flat sheets known as wavefronts. Gentle wavefront lights enter the eye, pass through the entire optical system (cornea, lens and retina) and are then reflected back into the WaveScan sensors.

The WaveScan system compares the reflected wavefronts with the original unaltered wavefronts. This produces a fingerprint of your vision, or WavePrint Map. This information is then transferred to the Visx S4 Laser and is used as a guide to reshape the cornea during your laser vision treatment.
