Treatment of Refractory Keratitis After a Boston Type I Keratoprosthesis With Corneal Collagen Cross-Linking.

PURPOSE To report a patient with refractory keratitis after a Boston type I keratoprosthesis treated with corneal collagen cross-linking (CXL). METHODS Case report. RESULTS A 29-year-old man with a history of chemical burn in the left eye underwent keratoprosthesis implantation. He developed infectious keratitis 4 months after surgery, which did not respond to topical antibiotics. The patient underwent corneal CXL with a shield covering the keratoprosthesis optic. Three weeks after CXL, the infiltration completely resolved. CONCLUSIONS Corneal CXL might be beneficial in the treatment of refractory keratitis in patients with the Boston type I keratoprosthesis.
