RK Thirty Years Ago
This is a photo of an eye that underwent Radial Keratotomy (RK) about 30 years ago. Fluorescein dye was instilled on the ocular surface to make the RK incisions more visible. Note the yellow-green dye within the deep RK incisions. This tells you that these incisions never closed. In addition, virtually every post-RK cornea is irregular and dry. Last year this eye underwent cataract surgery. During the surgery, the vertical incision extending downward from 12:00 ruptured forcing the cataract surgeon to suture the open wound. Note the increased staining in the superior portion of this cornea. Without correction, this patient not only has poor vision with this eye but also extreme discomfort (burning, dryness etc.). This patient is now wearing a scleral lens on this eye which is not only protecting this compromised eye from the environment and the blinking action of the eyelids but also providing this patient with clear, stable vision once again. Scleral lenses are now the “standard of care” when it comes to treating post-refractive surgical corneas. That is corneas that have been altered by LASIK, Radial Keratotomy and a host of other harmful, unnecessary surgeries.
