The first step in laser vision correction is the creation of a WavePrint™ Map of the eye. Essentially a fingerprint of your vision, the WavePrint™ Map is derived from a precise and individualized measurement. During the diagnostic phase,   the WaveScan WaveFront™ System creates this detailed map of each patient's eye, and this WavePrint™ Map is then used during the treatment phase to perform the vision correction.

The WaveScan WaveFront™ System, featuring Fourier algorithms, is an FDA-approved advancement in wavefront technology that delivers the highest available resolution of your wavefront correction. WaveScan™ technology - originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space - has now been applied to laser vision correction, to identify unique imperfections in the eye. In fact, WaveScan™-based digital technology identifies and measures imperfections in a patient's eye 25 times more precisely than standard methods used for glasses and contact lenses. Physicians transfer this information (the WavePrint™ Map) to the laser to treat individuals with the Advanced CustomVue™ procedure.

This new level of precision provided by the WaveScan WaveFront™ System with Fourier algorithms overcomes the limitations of previous technology, delivering unprecedented resolution to ensure the most effective individualized advanced laser treatment available today: Advanced CustomVue™ *
