Abstract
A 30-year-old man was referred as an acute case for keratitis. Two days earlier he hadhad photorefractive keratectomy for myopia at another clinic; a bandage contact lens was placed over the eye, but prophylactic antibiotics were not prescribed. The keratitis was treated with gentamicin sulfate (Garamycin®) and chloramphenicol eyedrops. Scrapings from the cornea showed nonhemolytic streptococci. Two and a half months later, visual acuity was finger counting because of gross distortion of the corneal contour. The combination of a bandage contact lens and the lack of prophylactic antibiotics may have been the source of bacterial keratitis.
