Scleral Contact Lenses

Scleral contact lenses are rigid, gas-permeable lenses that are designed to fit over the whole surface of the cornea and a large portion of the sclera rather than just across the iris, as with conventional RGP lenses.

If you have been told that your vision problems make you a poor candidate for soft contacts, then scleral contact lenses might be the answer to your needs.

What Are Scleral Lenses?
Scleral contact lenses are rigid, gas-permeable lenses that are designed to fit over the whole surface of the cornea and a large portion of the sclera (white part of the eye) rather than just across the iris, as with soft contact lenses.

Using the latest corneal topography technology, Dr. Mao will design customized scleral lenses that exactly match the curve of your eyes. This curved optical surface allows scleral lenses to fit snugly onto your eye, providing a clear vision for people with a prescription that goes beyond the parameters of soft contacts.
