Scleral contacts have a variety of uses. Their main application is for the correction of vision in patients with irregular corneas. The common causes of irregular cornea include corneal disease such as keratoconus, pellucid marginal degeneration, salzmann’s nodules and others.
Certain eye surgeries can also result in an irregular cornea, including corneal transplant, refractive keratotomy (RK), and LASIK. Corneal trauma can lead to scarring that also causes irregularity. Scleral lenses cover up the irregularity of the these corneas and creates a new, spherical ocular surface to properly focus light.
Scleral lenses also have therapeutic benefits. Dr. Andrew Biondo uses them for patients with dry eye syndrome. The lenses bathe the cornea in hydrating saline throughout the day that can allow patients with all degrees of dry eye to function normally in all indoor and outdoor conditions. This works especially well for patients with severe dry eye resulting from sjogren’s syndrome, rheumatoid arthritis, graft-versus-host disease and other systemic conditions. It also works well for patients who experience dehydration and dryness with their soft lenses. The scleral lens corrects astigmatism as well for people who wear toric soft lenses.
While scleral lenses are ‘hard’ or ‘rigid’ gas permeable lenses, they are not uncomfortable like the older, smaller GP and hard lenes. In fact, Dr. Biondo participated in a study that showed them to be as comfortable, or even more comfortable, than soft lenses for many patients.
Dr. Andrew Biondo specializes in the fitting of scleral lenses for all types of conditions and is a fellow of the Scleral Lens Society. He travels throughout the country every month to help teach other physicians how to properly use this exciting new technology.
