Pellucid Marginal Degeneration
Post-refractive surgical complications due to LASIK, Radial Keratotomy, PRK and so on.
Complications resulting from corneal transplant surgery
Chronic dry eye due to systemic disease, medications and cancer and other therapies.
A variety of corneal degenerations and dystrophies such as Stevens-Johnson Syndrome, Sjogrens Syndrome and Fuchs dystrophy. Corneal damage due to ocular trauma, chemical and burn injuries and eyelid abnormalities. Diseases of the tear gland, tear duct and the glands that produce the oils that compromise part of a normal tear film.
The diseases and conditions written above are not a complete list of causes..Many patients suffer ocular surface disease from unknown causes. If the ocular surface is inflamed and compromised, then it goes without saying that the patient’s vision will also suffer. At the present time there are a number of treatments and therapies involving eyedrops. Almost all the these treatments may be effective, but only for a brief period of time, perhaps only hours.
In recent years, scleral lenses have become the standard of care for the treatment of patients suffering vision loss due to ocular surface disease. The reason for this is that this is the only technology that will protect the eye from the environment
and the blinking action of the eyelids while at the same time providing the patient with clear, comfortable vision. In addition, the scleral lens does not touch the cornea. Instead, this lens vaults over the cornea and is supported by the white portion of the eye (known as the sclera). The space between the back surface of the scleral lens and the front surface of the compromised cornea is
filled with unpreserved saline solution. In other words, the compromised or disease corneal tissue is always in a moist environment, perfect for a healing process to take place.
