Fluctuating Radial Keratomy Vision Corrected to 20/20 with GVR Scleral Lens
The patient in this photo underwent Radial Keratotomy (R-K) eye surgery in 1990 for the purpose of eliminating his myopia and astigmatism and his dependence on eyeglasses. For many years his post-surgical vision was very good. In recent years his vision began to deteriorate. He noticed that his vision was not stable and would fluctuate depending on the day, the time of the day and the surrounding lighting conditions. Last year he underwent Collagen Cross-Linking treatment in both eyes in an effort to stabilize his corneas and to improve his uncorrected visual acuity. Six weeks ago we fit this patient with GVR Scleral lenses. For the first time in many years he is seeing clearly (20/20) and comfortably with all day lens wear. In addition, his vision is stable regardless of the surrounding lighting conditions. In the lower photo can be seen the deeply scarred R-K incisions in his cornea. These incisions are still open 25 years after the R-K surgery was done. Over this scarred cornea is a GVR Scleral lens. In addition to allowing this eye to see clearly once again, this scleral lens protects the compromised cornea from the environment and the blinking action of the eyelids.
