Multifocal lamellar keratitis following laser in situ keratomileusis

Abstract

Over a period of approximately 7 months, multiple subepithelial spots were noted in one or both corneas of some patients examined 2 to 6 months after laser in situ keratomileusis (LASIK). The lesions appeared identical to adenovirus keratitis. The eyes were quiet, had good vision, and no patient had a history of adenoviral keratoconjunctivitis. In all eyes, the lesions resolved spontaneously or with topical steroid eyedrops. All investigations were negative for adenovirus. Corneal laser scanning in vivo confocal microscopy revealed Langerhans cells in the epithelium, which disappeared after the lesions resolved.
