Why do scleral lenses work well with keratoconus?
Scleral lenses do not touch or rest on the irritated corneal tissue. Instead these lenses vault over the cornea and are supported by the white portion (the sclera) of the eye. A special fluid fills the space between the back portion of the lens and the front of the cornea. There is very little lens movement and the edges of the lens are beneath the eyelids. Due to the increased stability of these lenses over conventional gas permeable lenses, comfort and vision is usually excellent. In addition, the fluid environment between the back of the lens and the front of the cornea tends to promote healing of the irritated corneal tissue. My doctor says that my keratoconus is mild yet I can’t seem to tolerate my contact lenses and the vision with my glasses is getting worse. My doctor has tried everything. Will scleral lenses work for me? The use of scleral lenses in keratoconus is not related to the severity of the disease. Patients with mild keratoconus can be fitted with gas permeable sclera
