Keratitis with loss of useful vision after photorefractive keratectomy

A 30-year-old man was referred as an acute case for keratitis. Two days earlier he had had 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(TM)) 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.
