A scleral lens covers both the cornea and the sclera, the white part of the eye. The lens itself rests on the sclera, taking the pressure off the more sensitive cornea. Because of this, a scleral lens tends to be more comfortable to wear.
The lens is a rigid, gas permeable lens that offers many advantages over typical, corneal lenses, in addition to the comfort of wear. In addition, because of the size of the lens—extending under the upper and lower lids—a scleral lens will rarely dislocate, leading to stability and keeping the lens centered on the eye.
Scleral contact lenses are indicated to improve the vision in patients with corneal irregularities including:
Post-Radial Keratotomy (RK)
Post Corneal Transplants
Treatment with scleral contacts can also provide relief for patients with ocular surface disease. These can include:
Dry Eye Syndrome
Ocular Chronic Graft Versus Host Disease (GVHD)
History of Ocular Herpes (Shingles) and AutoImmune disorders (eg. Rheumatoid Arthritis)
Patients with refractive errors may also benefit from a scleral lens.
