Abstract
A 54-year-old man with −10.00 to −11.00 diopters (D) of myopia in both eyes underwent uncomplicated radial keratotomy (RK) in his left eye in December 1986 and in his right eye in May 1987. Within several months after the second RK he experienced gradually declining visual acuity. The patient was treated with topical steroids with no effect. Within 18 months after surgery his condition had stabilized. Report of a Case. —We first examined the patient 38 months after the second RK. Best corrected visual acuity was 20/30+ OD with −3.00 sphere and 20/60− OS with −2.00 sphere. No decrease in visual acuity was noted in bright light. Keratometry measured 38.50/39.50 at 170 OD and 38.25/38.62 at 180 OS with mild distortion in both eyes. Biomicroscopy revealed bilateral eight-incision RK with 2-mm central clear zones. Incisions did not extend into the central optical zones. Mild superficial peripheral corneal vascularization was
