Wavefront guided laser vision correction is performed with The WaveScan System by VISX®. The components of this system include:

• The WaveScan Map;
• 3D ActiveTrak Eyetracker; and
• Variable Spot Scanning

The WaveScan Map shows the variability of how light is focused in different areas of your eye, giving your surgeon a new level of diagnostic information to personalize your treatment plan. 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. In addition to measuring myopia and astigmatism, it can measure other abnormalities (higher order distortions) in your optical system, so the laser can correct these as well. These abnormalities are unique to each individual, much like a fingerprint.

The 3D ActiveTrak Eyetracker follows the tiny movement of your eye in all three dimensions, repositioning the laser to ensure accuracy. Used with our VISX S4 excimer laser, the Eyetracker helps your surgeon guide the laser through your treatment plan with greater accuracy.

The Visx S4 Variable Spot Scanning (VSS) excimer laser allows for more accurate reshaping of your eye using your unique WavePrint profile. It also offers your surgeon greater flexibility in developing a more personalized laser vision procedure when pupil size may be a consideration.

The 3D ActiveTrak Eyetracker along with the Variable Spot Scanning ability of the VISX S4 excimer laser, allow for treatment of both your glasses prescription and high order distortions. These distortions contribute to the ghosting, halos, and starbursts that some patients experience after laser surgery.
