Wavefront Technology

This technology is able to measure and correct imperfections which could not be detected before by standard methods, while doing so with greater accuracy and precision.

The Wall Street Journal, May 27, 2003:
"Wavefront technology has been shown to give patients consistently better vision and reduced side effects as compared with earlier techniques. This new procedure, sometimes called custom Lasik, creates precise, individualized measurements of imperfections in the patient's eye before beginning corrections. During the FDA trials, 98% of patients achieved 20/20 or better uncorrected visual acuity after the surgery and most reported their night vision had improved."

What is Wavefront technology?
Wavefront technology was derived from principles first applied to correct distortions of light waves from space. This allowed researchers to accurately view images of stars and planets. Waveprint * technology uses the same principles to measure light waves as they travel through your eye thereby determining the refractive errors and aberrations of your entire optical system. This provides the most complete picture of your eye ever available and the most precise and detailed analysis of your vision. A "picture" is taken of your eye and a "Waveprint Map"* is created. Like your fingerprint, your Waveprint Map is unique to you. Dr. Muller uses your Waveprint Map to gain a detailed understanding of your vision requirements to develop a laser vision correction (LVC) treatment plan that is personalized exactly to your unique eye.

In summary, Wavefront (or Waveprint) technology:

  • Gives Dr. Muller a detailed understanding of your vision correction requirements
  • Reveals the way your entire optical system processes light
  • Provides a new level of diagnostic information previously unavailable (25 times more precise than what was previously measurable by standard methods for glasses and contact lenses)
  • Allows a treatment plan to be personalized to your unique vision

* Waveprint and Waveprint Map, are the trademark names VISX uses for wavefront technology

Commonly Asked Questions

Q: Does the Waveprint mapping hurt?


Q: What does a Waveprint Map look like?

The Waveprint Map is a brightly colored diagram of your vision. The different colors show Dr. Muller how light is moving through your eye - for example, red shows areas in which light moves quickly, blue shows areas in which light is moving slowly.

Q: What does the WavePrint Map show?

The WavePrint Map shows us the refractive state of the eye much the same as we try to do with glasses and an eye chart. However, the WavePrint Map provides a much more precise and detailed analysis of the visual characteristics of your eyes-like a "fingerprint," so to speak. The WavePrint Map shows visual imperfections that were previously undetectable with standard methods used for glasses and contact lenses. Information from the WavePrint Map is used to plan an individualized treatment for each person.

Q: How is the WavePrint different from other mapping systems?

The WavePrint Map provides information on more than just the surface of your eye. It reveals the way your entire eye processes light, allowing a more personalized treatment.

Q: 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.

Q: Why should I request a WavePrint Map?

The WavePrint Map is one of the tests which allow Dr. Muller to accurately assess whether you're a good candidate for laser vision correction. Anyone who is considering laser vision correction should obtain a WavePrint Map.

Q: What is CustomVue laser vision correction?

VISX CustomVue is an individualized laser vision correction treatment that is WaveScan-guided. This enables Dr. Muller 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.

Q: 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.

Q: What can the 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.

Q: Is the CustomVue procedure FDA approved?

Based on the clinical study, the U.S. FDA has approved the CustomVue procedure as safe and effective.

Q: What are some of the results of CustomVue to date?

In the FDA study, one year after the VISX CustomVue procedure:

  • 100% of participants could pass a driving test without glasses or contact lenses
  • 98% of participants could see 20/20 or better without glasses or contact lenses
  • 70% of participants could see better than 20/20 without glasses or contact lenses

In addition, many participants reported that they had clearer, better vision both during the day and at night, compared to their vision with glasses or contact lenses before the procedures.

Q: What does better than 20/20 mean?

20/20 is the current standard for excellence in vision. But, as shown in clinical study, individuals with the CustomVue procedure have the potential to see even better than 20/20. In fact, one year after the CustomVue procedure nearly 70 percent of clinical study participants saw 20/16, or better.

Q: Can the CustomVue procedure improve my night vision?

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

Other advantages in excimer laser technology which offer patients tremendous advantages:
1: Active Trak TM 3-D Eye Tracker

Infrared cameras actively follow the tiniest motions of your eye in all three dimensions so you can relax during your surgery - knowing the procedure will be delivered accurately.

2: Active Trak 3-D Automatic Centering

Enables Doctor Muller to precisely identify the center of your pupil and keep the laser centered to within 50 microns (about the width of a human hair) even if your eye moves.

3: Variable Spot Scanning (VSSTM)1

Allows for a larger treatment area and gives Doctor Muller greater flexibility to personalize your laser vision correction treatment when pupil size is a consideration.

Doctor Muller's excimer laser of choice is the VISX S4 because of its unparalleled safety and efficacy (she, personally, has decades of experience using it). You should feel confident knowing that:

Millions of Eyes Treated
VISX excimer lasers have been used to successfully treat over 3 million eyes in the U.S. and over 5 million eyes globally, so you can have confidence in the VISX technology.

More Doctors use VISX Lasers than any other Laser Vision Correction (LVC) Lasers
More doctors use VISX excimer lasers across the U.S. and around the world than any other LVC laser system, so you can have confidence in Dr. Muller's choice.

More VISX Lasers than all others Combined
There are more VISX excimer lasers used to perform LVC in the U.S. than all other brands combined, so you can believe in the industry's choice.

The Company that Pioneered LVC Surgery
VISX was the company that developed excimer laser technology for LVC and gained clearance from the U.S. FDA in 1995 for correcting a variety of vision conditions.

Unparalleled Commitment to LVC Technology
The VISX investment in leading LVC research and development is tops in the industry.

The entire VISX WavePrint System includes:

  • The WavePrintTM Map
  • 3D Active Trak Eyetracker
  • Variable Spot Scaning* (VSSTM)

Now, with the WavePrint Map, Dr. Muller can literally personalize your treatment plan to your unique eyes / vision.
