Abstract:  CWhatUC : Software Tools for Predicting, Visualizing and Simulating Corneal Visual Acuity by Daniel Dante Garcia Doctor of Philosophy in Computer Science University of California at Berkeley Professor Brian A. Barsky, Chair The cornea is the transparent tissue covering the front of the eye, and performs about two-thirds of the refraction, or bending of lightinto the eye. Thus, subtle variations in its shape signicantly aect a patient's visual acuity. Clinicians need to know the shape and refractive contribution of the cornea for several reasons: corneal refractive surgery, contact lens tting and diagnosis of eye conditions. Instruments that measure the cornea's topography are called corneal topographers (CTs), and they have recently become a quite common tool for clinicians. These devices typically shine rings of lightonto the cornea and capture the reection pattern with a video camera. The raw data is extracted from the CT and a spline surface representation is constructed ...
