We have heard a lot about scleral contact lenses, but what are these?
Scleral lenses are also a type of gas permeable lenses but with a larger diameter which may range from 14 to 20 mm. They get the name “scleral” because the lens covers the cornea entirely and rests on the white part of the eye called sclera. There are different types of scleral lenses based on their diameter and fitting properties namely corneal lenses, mini-scleral lenses, corneoscleral lenses, and scleral lenses.
Scleral lenses offer more comfort to people suffering from keratoconus, corneal ectasia and other eye conditions as these rests on the sclera and not completely on the cornea.
It is a progressive disease which results in an irregular shape of the cornea. It is caused in very few people and leads the cornea to become thin and bulge. This causes a very unclear vision. The use of scleral lenses can solve the problem of Keratoconus to an extent. As the scleral lenses rest on the sclera, the highly sensitive and innervated cornea is completely bound by the lens offering visual stability and more comfort.
Post-Lasik Corneal Ectasia
Corneal ectasia is either iatrogenically or genetically caused. Scleral lenses are preferred in a moderate to a bit advanced stage of post lasik corneal ectasia. The large scleral lens offers more comfort and protection for people with a cone-shaped cornea by completely covering the cornea and reducing the friction. Patients who are not comfortable with normal lenses have found scleral lenses to clear this issue as there is not much contact with the cornea and rests on the sclera.
