Ex Vivo Study of Transepithelial Corneal Cross-linking.

PURPOSE To perform in vitro assessment of different techniques of transepithelial corneal cross-linking (CXL) and to compare the results to deepithelialized CXL. METHODS Transepithelial CXL was performed after pre-treatment with or without penetration enhancers (gum cellulose, 0.44% sodium chloride, and 0.01% benzalkonium chloride) for 15 or 60 minutes… (More)
