"I marvel at a society that will pay for a corneal transplant but not for a scleral lens that could save the eye."Dr. Edward Boshnick
Our office uses Ocular Surface Tomography and proprietary software designed by Zeiss Optical which allows us to create Scleral Lenses with the proper diameter and curvatures needed for your eye. This technology permits us to determine within microns the necessary clearance required to vault over each individual cornea.
Doctor Boshnick designs Scleral Lenses to be unique for each individual patient and eye because no two eyes are the same and no two patients have exactly the same vision and ocular issues. our goals with these unique lenses are:
Our Patient Regains 20/20 Vision After 14 Years Of Blindness
Troy Thomas was blinded from Stevens-Johnson Syndrome from 1990 until August 2004. Troy is shown standing next to his beautiful bride Shay while holding up his Florida driver's license and standing next to his new car. His corrected visual acuity with his scleral lens is 20/20.

Scleral lenses are a unique type of lens designed to treat a variety of eye conditions which do not respond to any other type of therapy. The new generation of scleral lenses being used today are made from a highly oxygen permeable polymer and are unique in that they are fit onto and supported by the sclera (the white portion of the eye).
Because these lenses vault over the compromised cornea and fit under the eyelids, they are extremely comfortable and are almost never dislodged accidentally.
The space between the front of the cornea and the back surface of the scleral lens is filled with artificial tears. This liquid reservoir fills in the surface irregularities of the cornea allowing vision to be restored in a comfortable manner. The lens and the fluid liquid bandage beneath it protect the cornea from exposure to air and the rubbing effects of blinking. This cushion of fluid beneath the lens also provides oxygen to the cornea allowing the eye to heal. The effect is to create a smooth optical surface over the diseased cornea that replaces the distorted surface to improve vision often dramatically.
Our unique proprietary scleral lenses can replace the need for corneal transplant surgery which has a potential for serious complications, long healing period and uncertain visual outcome. When corneal transplant surgery fails, our lens designs can enable patients to recover lost vision. In other words, these unique lenses provide a non-surgical means of restoring lost vision and act in a therapeutic manner.
Over the years, many patients have come to our office seeking relief from the following devastating vision and ocular disorders: keratoconus, corneal ectasia resulting from lasik, post refractive surgical complications, distorted corneal transplants, Stevens-Johnson Syndrome, Sjogren’s Syndrome, corneal degenerations and dystrophies, eyelid abnormalities, chemical and burn injuries to the eye, aniridia, and pellucid degeneration. Scleral lenses have been the therapy of choice in treating all of these conditions with an extremely high rate of success.
The Scleral Lens is in fact a medical and therapeutic device that can be fitted to virtually any eye shape and for any degree of visual error while allowing the diseased/injured eye to heal. It is important to understand that Scleral Lenses are custom made for each patient. Therefore, the ability of the doctor to fit these lenses demands greater experience and more time than fitting conventional soft or rigid gas permeable lenses. Computerized Topographical Maps of the entire corneal surface are generated to facilitate the lens size and fitting. In addition, several diagnostic Scleral Lenses of varying curvatures and diameters may be applied to the eye during the fitting process.
Depending on the complexity of the eye and the condition of the ocular surface, adjustments of the lens parameters may be needed. This will require additional lenses to be made and exchanged. The entire scleral lens fitting process can take several visits to determine the optimal lens for each eye.
