Two cases of methicillin-resistant Staphylococcus aureus keratitis after Epi-LASIK.
BACKGROUND
We describe two severe cases of methicillin-resistant Staphylococcus aureus (MRSA) keratitis following Epi-LASIK surgery.


METHODS
One patient was a 23-year-old man who underwent Epi-LASIK surgery in both eyes. He developed an infectious corneal ulcer in one eye 2 days after surgery and was referred to us 7 days post-surgery with corneal perforation, for which we performed therapeutic penetrating keratoplasty. The other patient was a 32-year-old man who developed infectious keratitis in one eye 4 days after bilateral Epi-LASIK and was referred to us 2 days later.


METHODS
Microbial testing revealed MRSA infection as the cause of the keratitis in both patients which was successfully treated with vancomycin eyedrops.


CONCLUSIONS
Infectious keratitis after refractive surgery is uncommon; it is important to diagnose this condition, identify the causative agent, and initiate treatment with appropriate antibiotics as soon as possible.
