Why Aberrometry or wavefront analysis?
An aberrometer is a diagnostic device that provides novel measuring standards (wavefront analysis). Whereas a traditional LASIK is based on correction values that were determined with eyeglasses or contact lenses, the aberrometer measures the refractive power of the eye at more than 200 different spots. It produces a "map of the eye", which contains the precise refractive power for every measured spot and is often called "fingerprint of your vision".

This map is later used to perform the vision correction by taking tiny differences in the refractive power of the eye or of the cornea as well as higher order aberrations into account, therefore optimizing the result.

The WaveScan Wavefront System supports iris recognition and is connected to the VISX Excimer Laser System for an optimized ablation.
