Severe late-onset recurrent epithelial erosion with diffuse lamellar keratitis after laser in situ keratomileusis.
A 39-year-old woman had laser in situ keratomileusis that was complicated by intraoperative epithelial erosion in both eyes. Seven months after surgery, the patient returned, complaining of pain and blurred vision in the left eye. Slitlamp examination revealed corneal epithelial erosion with severe diffuse lamellar keratitis (DLK). Reepithelialization was complete in several days. However, severe inflammation remained until systemic steroids were administered. Recurrent erosions can lead to a serious inflammatory reaction such as DLK because of the presence of the flap-stroma interface.
