Wavefront Technology: Wavefront Technology

Flat sheets of light (wavefronts) passing through the eye are distorted by the imperfect refractive medium. The wavefront "wrinkles" on its way through an irregular cornea or lens.

Simple refractive errors like nearsightedness or farsightedness would result in a simple bowl-like symmetrical wavefront distortion. But higher order aberrations yield a complex non-symmetrical distortion ofthe originally flat wavefront, which is unique for every singleperson's eye. These wavefront distortions lead to blurred optical imaging of viewed scenes and they cannot be compensated for by glasses or normal contact lenses.

With the compact and highly integrated wavefront sensing technology,you are able to measure the simple refractive errors as well as the higher order aberrations with unsurpassed precision. This wavefront data can be used by very precise excimer laser systems using highly customized laser surgical procedures based on the measured wavefront to correct these aberrations.

20/10 PERFECT VISION publicly presented the WaveScan™ wavefront diagnostic devices for the first time at the AAO show in Orlando,Florida, in October 1999. Since then, 20/10 PERFECT VISION has been the worldwide technology leader for solutions for the Personalized VisionCare™ market. The WaveScan™ became the first FDA-approved wavefront diagnostic device (510(k), in May 2000).

In April 2003, VISX (now: AMO) acquired the rights and technology to the 20/10 PERFECT VISION WaveScan product line. By now it is with about1500 shipped units one of the most successful ophthalmic wavefront systems in the world.
