OPtics and Topography Involving the Cornea And Lens


Project Overview

Welcome to the home page for the OPTICAL research project. This project is studying the cornea, the front part of the eye that is responsible for three quarters of the light refraction in the eye. Visual correction through contact lenses or recently developed corneal surgeries require precise information about the shape of the cornea. Through the use of geometric modeling and scientific visualization, this project is developing sophisticated techniques to provide improved shape representations of patients' corneas. We are affiliated with the Computer Graphics group in the Computer Science Division at the University of California, Berkeley. This research is in collaboration with the School of Optometry and the Vision Science Group at Berkeley.
