The human cornea is extremely fragile and subject to accidental injury and various disease processes. When this occurs, a corneal transplant may be performed to restore eyesight. Unfortunately, in many cases, corneal transplantation does not provide clear vision for the patient without additional treatment such as gas permeable contact lenses.
In 1999 Drs. Buffington & Lilley were successful in developing a revolutionary contact lens designed specifically for corneal transplant patients. This new lens has been proven an unparalleled success.

The proprietary design is now being patented for the exclusive use of corneal transplant patients. Ultimately, this design will be available throughout the United States and worldwide.

This innovative design is based on new technology called "reverse geometry". In a conventional contact lens design, the edges of the lens bevel up and away from the eye. On corneal transplants, the lenses slide around and can easily pop out as illustrated in the drawing below.
With our new reverse geometry design, the edges of the lens do the reverse of a conventional design, they bevel down toward the eye. This allows the lens to lock on to the transplant, resulting in a stable fit. This is illustrated in the drawing below.
Our office maintains a large fitting set of reverse geometry lenses for transplant patients. Frequently, we can fit the patient the same day as the initial examination.
