Bacterial keratitis following laser in situ keratomileusis for hyperopia.

A 42-year-old Bahraini man had uneventful laser in situ keratomileusis for hyperopia (OD: +3.00 +0.75 x 155 degrees; OS: +2.00 +0.50 x 155 degrees). Three weeks later, he presented with localized keratitis in his right eye, with localized keratitis at the flap margin with stromal edema. Uncorrected visual acuity was 20/80 OD with no improvement with pinhole, and was 20/20 OS. Corneal smear culture showed a positive growth of Staphylococcus aureus. The patient was immediately treated with subconjunctival gentamicin and intensive topical ofloxacin 0.3% with systemic cephalosporin. The patient recovered from keratitis within 2 weeks and his uncorrected visual acuity OD improved to 20/20. Keratitis following LASIK should be treated promptly so that it does not lead to permanent reduction in visual acuity.
