A 25-year-old woman presented with redness, pain, and diminution of vision that occurred 2 weeks after microkeratome-assisted laser in situ keratomileusis (LASIK). On presentation, corneal edema, Descemet membrane folds, keratic precipitates, stromal infiltrates, and flap necrosis were observed. Delayed post-LASIK microbial keratitis was diagnosed. The patient had no history of ocular herpes. Culture and scraping showed no organisms. Immunofluorescence stain was positive for the herpes simplex virus antigen. The patient was started on oral valacyclovir, and progress was monitored through serial clinical photographs and anterior segment optical coherence tomography. Resolution began within 3 days of initiating treatment and was complete in 4 weeks.
