The clear, protective, outermost layer of the eye is the cornea. Its dome-shaped surface covers the front of the eye and is considered the most important tissue for vision. Along with the sclera (white of the eye), the cornea serves as a barrier against germs and other elements that can harm the eye’s components. All the light that enters the eye is bent by the cornea. If the cornea becomes damaged through disease, infection, or injury, the resulting scars or discoloration interferes with vision by blocking light from entering the eye.
The Cornea and External disease center is headed by Dr. Edgar Espana, who performs cutting-edge surgery along with NIH-sponsored research.
