Identification of Corneal Aberrations by using Computer Techniques

Abstract

The objective was to study the relative contributions of optical aberrations of the cornea and determine the irregularities across its surface area. Corneal topographic imaging data is used and corneal aberrations are computed by using corneal height maps. Mathematical modeling of cornea surface is developed by using Zernike polynomials and they are compared with the patient corneas.  Simulation techniques are utilized to determine the amount of corrections with respect to an ideal cornea in computer environment.
