If you have an eye condition that prevents you from wearing regular contact lenses, such as corneal irregularities (i.e. keratoconus), post corneal transplant, severe dry-eye, or an unusually high refractive error, scleral contact lenses may be the right option for you.
Scleral contact lenses are large-diameter gas permeable lenses specially designed to fit over the cornea and extend onto the white of the eye which is known as the sclera. Scleral lenses functionally replace the irregular cornea with a perfectly smooth optical surface to correct vision problems caused by keratoconus and other corneal irregularities. The space between the cornea and the back surface of a scleral lens acts as a fluid reservoir to provide comfort for people with severe dry eyes who otherwise could not tolerate contact lens wear.
Scleral lenses are custom fit lenses which require in depth knowledge, expertise and the use of advanced diagnostic equipment. Dr. Johnson is known for his special expertise in fitting scleral contact lenses.
Scleral Contact Lenses are used to correct vision in a number of conditions, such as:
Post refractive surgical corneal issues and deformities
Ocular surface disease
Severe dry eye
