Corneal Contact Lenses and<br />

Corneal Oxygen Transport<br />

Dr. Weissman continues to study the optics and physiological<br />

tolerance of contact lens systems. He has<br />

specified a model that predicts optical changes that are<br />

induced when a hydrogel (soft) contact lens “wraps”<br />

onto a human cornea. He has also published an optical<br />

model of piggyback contact lens systems. Dr. Weissman<br />

investigates the severe complications occasionally<br />

encountered with contact lens wear, such as neovascularization,<br />

abrasion, and corneal infection, and he has<br />

published several recent large cohort series. He is<br />

interested in systems for oxygen supply to the corneas<br />

of contact lens wearers, and in the ability of contact<br />

lenses and emerging ophthalmic devices to transmit<br />

oxygen, and he developed a model to predict the tear<br />

layer oxygen under different contact lens designs,<br />

including piggyback lens systems. Keratoconus, a<br />

corneal disease treated with contact lenses, is another<br />

area of interest. Dr. Weissman was the principal investigator<br />

for the UCLA center of the National <strong>Eye</strong> <strong>Institute</strong>sponsored<br />

Collaborative Longitudinal Evaluation of<br />

Keratoconus (CLEK) study.<br />
