Boston PRK is performed by Dr Ernest Kornmehl, a refractive surgery specialist. On this webpage, Dr Kornmehl provides information about PRK refractive surgery and how it has improved the vision of many of his patients. PRK or Photo-Refractive Keratectomy treats refractive errors by removing tissue from the surface of the cornea. First, your eye is numbed using a topical eye drop anesthesia. Then, the surgeon removes the epithelium, a thin layer of protective skin that covers the cornea. This may be done with either a blade, a brush or even the excimer laser. During the actual procedure, the patient stares at a fixation light. In less than a minute, the laser removes the proper amount of tissue while it reshapes the surface of the cornea.
After PRK, a bandage lens is placed on the cornea for 3 – 5 days. Because the epithelium was removed, patients may experience blurry vision for three to five days and a mild to moderate amount of discomfort until the epithelium heals and covers the treated area. Eye drops, and narcotics are effective in reducing this post-operative discomfort. Final visual results may be fully realized anywhere from several days to a few months or more as the surface heals in accordance to each individual’s healing tendencies. PRK is most often used to treat low to high amounts of nearsightedness and astigmatism.
