Scleral Lenses Can Restore Your Vision
Scleral lenses are used to treat a variety of conditions, including:
Corneal Cross-Linking (CXL) Complications
Glare, Dry Eyes, Halos, Starbursts, and Ghosting
Complications from LASIK, PRK, and RK
Pellucid Marginal Degeneration (PMD)
Scleral contact lenses are large-diameter lenses that provide clear and comfortable vision because the lenses do not actually touch the cornea. Instead, scleral lenses vault over the entire corneal surface, resting on the "sclera" or the "white" portion of the eyes. The space between the back and front portions of the scleral lens is filled with nonpreserved sterile saline solution, which keeps the eyes always moistened in a liquid environment. Scleral lenses cover a larger portion of the sclera, whereas semi-scleral lenses cover a smaller area. These larger lenses also are more stable than conventional gas-permeable contact lenses, and even soft contacts which tend to cause eye dryness in a day's worth. Moreover, scleral lenses do not fall out or dislodge into the folds of the eyelids during wear. They are surprisingly comfortable to wear when fitted properly.
Scleral lenses are typically manufactured with highly breathable, structurally sound polymer lens materials that permit plenty of liquid reservoir and oxygen exchanges for the wearer to enhance maximum comfort and health.
