Wavefront Analysis for Keratoconus

Abstract

Keratoconus is the most common primary corneal ectasia, involving a thinning of the central cornea, leading to irregular corneal astigmatism. Wavefront analysis is an evolving field in the area of corneal surgery, initially designed for laser refractive treatments, but today is growing in importance and application in the diagnosis and treatment of corneal disorders such as keratoconus. In this article we will review the theoretical background of high order aberrations and the wavefront analysis as a tool for the diagnosis of keratoconus.
