Purpose:
To evaluate the efficacy of ultraviolet-corneal cross-linking (CXL) for treating infectious melting keratitis.
Methods:
Five patients with infectious keratitis associated with corneal melting were treated with CXL at the outpatient departments of the Institut für Refraktive und Ophthalmo-Chirurgie and the eye hospital at the University of Zurich. CXL was performed when the infection did not respond to systemic and topical antibiotic therapy. Follow-up after cross-linking ranged from 1 to 9 months.
Results:
In all cases, the progression of corneal melting was halted after CXL treatment. Emergency keratoplasty was not necessary in any of the 5 cases presented.
Conclusions:
CXL is a promising option for treating patients with therapy-refractory infectious keratitis to avoid emergency keratoplasty.
