[Corneal ulcer caused by MRSA after UV/riboflavin cross-linking in a patient with bilateral keratoconus].

Riboflavin/UV cross-linking is a surgical method for stabilizing a progressive form of keratoconus which was developed in Germany and is now used worldwide. The procedure is considered to be safe and rarely results in complications. In this article we report the case of a 40-year-old male patient with a severe infection due to methicillin-resistant Staphylococcus aureus (MRSA) after uneventful cross-linking in the better eye. Despite intensive local and oral therapy the ulcer did not heal completely and penetrating keratoplasty had to be performed.
