Summary

The overall goal of this project is to improve the visual quality of individuals who have abnormal corneal conditions that alter the shape of their cornea (eg. keratoconus). Patients with an abnormal corneal shape have substantial lower and higher order aberrations (distortions in the eye). This results in reduced visual acuity which cannot be corrected by regular sphero-cylindrical correction. Compensating for these aberrations has been challenging due to difficulty measuring their wavefront aberrations accurately and, consequently, manufacturing the custom contact lenses with irregular optical profiles. This project is designed to systematically overcome these obstacles with a customized scleral and/or soft contact lens capable of compensating for the lower and higher order aberrations of the eye.
