Scleral Lenses

Several conditions are caused by problems with the cornea in the eye. Multiple forms of treatment are available to correct these problems, but not all treatments work for every patient. When other treatments are not working, patients can use scleral lenses to correct their vision. At Ritz and Johnson, our optometrists in Ocala will administer a comprehensive eye exam and discuss if scleral lenses are a good option for your vision.


What Are Scleral Lenses?

These lenses work much like standard contact lenses, but there are a few key differences. These contacts are larger than the standard contact lenses. They cover the center of the eye as well as part of the scleral, otherwise known as the white part of the eye. Scleral lenses are kept from coming into contact with the cornea by using a fluid barrier. These contacts may reduce your pain because they do not touch the cornea while providing vision correction.

Scleral lenses keep the front part of the eye protected when there is a problem such as exposure or neurotrophic keratopathy. They can also help with making the eye feel more comfortable when the patient has conditions such as Stevens-Johnson syndrome or dry eye. For people who have irregular corneal surfaces, these contacts can help them to see more clearly. Several things can make the corneal surface irregular, including corneal scarring and keratoconus. No matter what the corneal problem, these lenses can provide a soothing choice for vision correction.

The Sizes of Scleral Lenses

Scleral lenses are made especially for each patient so that they have an exact fit. In humans, the cornea averages about 11.8mm in diameter. Regular contact lenses cover most of that space. But with scleral lenses, they are much larger. The smallest ones measure about 14.5mm in diameter, while the largest can have a diameter of up to 24mm.

A Different Kind of Contact Lens

If you have been told that your corneal problem prevents you from being able to wear contacts, scleral lenses may be a good option. They can keep the cornea comfortable while delivering the vision correction of normal contact lenses. If you have cornea problems and are interested in scleral lenses, call Ritz and Johnson in Ocala, FL, today at (352) 732-7900 to speak with one of our optometrists.
