Methicillin-resistant Staphylococcus aureus keratitis after laser in situ keratomileusis

A 50-year-old man had uneventful bilateral laser in situ keratomileusis (LA SIK) for moderate myopia (-4.50 diopters sphere, both eyes). Twelve days po stoperatively, he developed unilateral bacterial keratitis. Cultures reveal ed methicillin-resistant Staphylococcus aureus. The antibiotic regimen was adjusted, and he regained an uncorrected visual acuity of 20/40 and a best spectacle-corrected visual acuity (BSCVA) of 20/15. Bacterial keratitis aft er LASIK is a rare occurrence, Aggressive use of cultures and fortified ant ibiotics can prevent significant loss of BSCVA, even when a resistant organ ism is the cause.
