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.
For example, scleral lens technology developments made in just the last decade include front surface toric lenses for residual astigmatism and toric peripheral curves for eyes with greater than average scleral toricity. A number of laboratories also offer reverse geometry design lenses and multifocal scleral lenses.
