For over 30 years my practice has been devoted to the non-surgical treatment of patients who have suffered loss of vision and ocular comfort due to the following conditions:

  • Keratoconus and Pellucid Marginal Degeneration
  • Post-Refractive Surgical Complications such as Corneal Ectasia, Dry Eye and
  • Reduction in Quality Vision
  • Irregular and Compromised Transplanted Corneas
  • Stevens-Johnson Syndrome
  • Corneal Dystrophies
  • Compromised Corneas Due to Ocular Trauma

Over these many years, I have developed one of the largest specialty scleral lens practices in North America. Very often this unique technology is the only non-surgical treatment that will restore quality vision and comfort to these patients. If you have patients who you feel could benefit from my services and these materials, please consider my office as a referral source. Please know that all patients will be sent back to your office with a detailed report including anterior segment photos. In addition, please feel free to contact me if you need assistance with a patient suffering from any of the above conditions.

Below are ocular photos of some of my patients' eyes with conditions which I have written about. All of these patients now have functional vision and comfort for the first time in many years. These patients are wearing gas permeable scleral lenses which I designed.

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:

  1. To eliminate blurred and distorted vision resulting in restored ocular comfort once again.
  2. To promote and restore healing to the compromised irregular cornea and adjacent ocular tissues.
  3. To protect the compromised cornea from the environment and the eyelids.

Stevens-Johnson Syndrome

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.

The following are photos of some of my patients with various eye conditions who have benefited from scleral lenses:

“This instrument is an Anterior Segment Ocular Coherence Tomographer (OCT) made by Zeiss Optical. We utilize this instrument to determine and measure the entire shape and thickness of the cornea and to evaluate the relationship of our scleral lenses with reference to the underlying cornea. With this instrument we can determine within 4 microns the clearance between the back surface of a scleral lens and the front surface of the cornea.”


Atlas Cornea Topographer

“This instrument is a Corneal Topographer made by Zeiss Optical. The purpose of this technology is to measure the exact elevations and depressions of the entire cornea. The Corneal Topographer gives us to ability to diagnosed corneal diseases and dystrophies much earlier. In addition, we can determine what contact or scleral lens technology will work best to correct a particular patient’s vision best.”
