A scleral lens is a large diameter lens made of a highly oxygen permeable material. It does not move on the eye and is capable of providing a patient with a complicated ocular condition with clear, stable vision with all day lens wearing comfort. A scleral lens is not a contact lens in the sense that it does not touch the cornea. Instead, a liquid reservoir exists between the back surface of the scleral lens and the front surface of the cornea. In other words, the front surface of the eye is always in a liquid environment.
In addition to keeping the eye moist, this liquid reservoir under the scleral lens allows vision to be restored. The scleral lens and the liquid bandage beneath it protect the cornea from exposure to the environment and from the eyelids rubbing against the compromised ocular surface. This cushion of fluid beneath the lens also provides oxygen to the cornea allowing healing to take place. We design all of our scleral lenses with the aid of special computers with proprietary software.
The result of the work that we do is to create a smooth optical surface over the diseased or compromised cornea that replaces it as an optical surface. Almost always, vision and comfort are improved dramatically.
