Impending corneal perforation after collagen cross-linking for herpetic keratitis

Abstract

Collagen crosslinking (CXL) has been proposed as a treatment for infectious keratitis. Given the insurgence of antibiotic-resistant microorganisms and frequent toxicity of topical medications, CXL may be a potential treatment for corneal infections. However, corneal infection is itself a possible complication of this treatment. We describe a case of severe corneal thinning and melting in a woman who had a CXL procedure as a treatment for herpetic keratitis.
