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.

WaveScan Technology
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.

PreVue® Lens
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.

What i s Wavefront/CustomVue Technology?

In the past, laser vision correction has only been able to treat nearsightedness, farsightedness, and astigmatism. These are considered “simple” refractive errors. However, there are many other “complex” aberrations or distortions that exist within the optical system of the eye.

Nearsightedness Astigmatism Complex Aberrations


These distortions occur naturally in all eyes in varying degrees. Many people have degraded vision due to complex aberrations in small amounts, but others have visually significant degradation in overall clarity of best-corrected vision because of them.

The FDA has approved wavefront‑guided LASIK with the VISX STAR 4 Excimer Laser, which automatically incorporates the correction of these complex distortions into the traditional LASIK procedure. This highly customized treatment is based on a wavefront analysis of the eye, which is essentially a “fingerprint” of that individual eye's optical system. This detailed information is used to help guide the laser. It is captured by the wavefront analyses (wave scan – Custom Vue)

The Result?

A customized cornea whose optical system has an unparalleled reduction in distortions. This dramatic improvement can mean the difference between just barely reading the small row of letters on the eye chart and reading it without effort. Many patients have reported an improvement in night vision.

How does Wavefront work?

Ideally in a perfect eye, all light would come to an exact point of focus on the back of the eye at the retina and bounce straight back out in a perfectly flat plane. In reality, all eyes have some degree of simple and complex imperfections.

Wavefront measures light that is reflected from the back of your eye out into a wavefront analyzer. This WaveScansystem separates the broad light into individual points of light that can be measured on a microscopic level. Each of these measured points of light results in a mathematical formula for the “error” at that exact point at the corneal plane. This data guides the ablation (reshaping) of your cornea by the Visx Excimer Laser.

Published Wavefront Results of the VISX Star 4 Excimer Laser guide by the CustomVue Wave Front Analyzer

6 months after treatment Before and After Night Vision Improvement as Reported by the Patient
• 100% of  eyes see 20/40 or better
• 94% of eyes see 20/20 or better
• 30% of eyes see better without correction after treatment than they did with glasses before treatment

Patients reported subjective improvement in all categories of quality of vision:

• sharpness
• visual comfort (improved 16.5%)
• consistency of vision
• daytime vision
• night vision (improved 20.2%)
• night vision glare (improved 21.1%)

Over 20% of patients who were dissatisfied or very dissatisfied with their night vision before treatment were no longer dissatisfied with their night vision after treatment.
