Wavefront Aberration Measurements of the Human Eye

Abstract

Wavefront sensing in the human eye recently has been extensively studied, because Liang used a Hartmann-Shack wavefront sensor to successfully measure the aberrations in the human eye. In this article, the basicmethods of a Hartmann-Shack wavefront sensor for the eye and several clinical applications will be described. The benefits of wavefront sensing will be observed in many clinical situations, such as in patients with keratoconusor cataract and in those undergoing intraocular lens implantation or corneal refractive surgery.
