Study Summary
High order aberrations (HOA) are visual phenomena that decrease quality of vision. Examples of high order aberration are glare, halos, decreased contrast sensitivity and shape distortion. They are caused by slight imperfections or distortions in the corneal surface. HOA are currently measured using a variety of FDA approved devices. For this study, the LADARWave (Alcon) will be used to measure HOA. This device uses a harmless beam of light. It is FDA approved and non-invasive. Contact lens induced high order aberrations have never been measured and reported in the literature. This work may provide information to guide future contact lens design.
