Item Contact lens design(2010-05) Pearson, Glen Dale; Iyer, Ram V.; Matthews, StevenThis thesis studies the design of a rigid gas permeable contact lens. The goal of this thesis is to present a method to design this type of contact lens. This lens will correct higher-order aberrations of a patient's eye based on wavefront measurement using the Shack-Hartman aberrometer. We can represent these wavefronts using Zernike Polynomials as basis functions for the space of continuous functions on a unit disc. The coe cients of the Zernike Polynomials represent various aberrations in the eye. We present a method to correct specifi c regions of the contact lens in front of the pupil. Another contribution in this thesis is a method of interpolating the corrected region of the contact lens with the uncorrected region.
