MRSA keratitis is rare complication

Link: Ophthalmology Times.

A 45-year-old male patient developed pain and a foreign-body sensation in his left eye 2 days after he had underwent uneventful bilateral LASIK. The patient was found to have a corneal infiltrate unresponsive to third-generation fluoroquinolone antibiotics. Laboratory investigation of corneal scrapings revealed methicillin-resistant Staphylococcus aureus (MRSA) keratitis. The keratitis responded to vancomycin, and the patient eventually developed a central scar. After excision of the overlying necrotic flap and application of topical mitomycin-C (Mutamycin, Bristol-Myers Oncology) to the underlying stroma, the patient's vision subsequently improved to 20/30. This paper provides a review of MRSA keratitis after LASIK and discusses the risk factors and the treatment options for this unusual, yet potentially serious, condition.
