Cherie B. Nau, O.D., has been involved in eye research for over 25 years. At the beginning of her career, she studied glaucoma, aqueous humor dynamics and corneal structures. Dr. Nau's current research focuses on the use of scleral contact lenses for treatment of corneal irregularities and ocular surface diseases. A scleral contact lens is a large, hard contact lens. It rests on the white part of the eye and has a smooth surface. An important aspect of Dr. Nau's current research is investigating the impact of disease and treatment modalities for people who use scleral lenses.
Scleral lenses are often the final option for individuals with vision that cannot be sufficiently corrected with spectacle lenses. Scleral lenses also protect and support the ocular surface in people with severe dry eye, ocular exposure or neurotrophic disease. For these people, scleral lenses allow improved vision and comfort. Scleral lenses may help maintain vision, stabilize the ocular surface and delay surgical interventions.
