Scleral lenses are large diameter gas permeable lenses that rest. beyond the limits of the cornea on the sclera. Successful fitting of. scleral lenses may defer surgical intervention and decrease the risk. of corneal scarring (4). Scleral lenses may be indicated for primary. and secondary corneal ectasias, post-corneal transplants, and.
Scleral lenses (15mm to 25mm) place all lens bearing on the sclera. Scleral lenses are further subdivided as: mini-scleral lenses (15mm to 18mm) which have a somewhat limited tear reservoir capacity, and full scleral lenses (18mm to 25mm) which have an almost unlimited tear reservoir capacity.
