Traditional LASIK surgery achieves a simple correction of focusing power by reshaping the cornea with the aid of a laser. Wavefront LASIK is a variation of that conventional procedure and accomplishes a spatially varying correction based on readings from a wavefront sensor. In essence, a wavefront sensor measures the eye itself. It detects any aberrations by directing a weak laser source into the eye, and by sampling and processing the reflection off the retina.
Wavefront measurements reveal the irregularities of the lens, which cause optical aberrations (any deviation from a desired perfect planar wavefront). Wavefront custom sculpts the cornea to accomplish corrected vision. In many ways, Wavefront offers better results than traditional LASIK. View the rest of this article
