Comparison of 2 Different Methods of Transepithelial Corneal Collagen Cross-Linking: Analysis of Corneal Histology and Hysteresis

Purpose: To compare the effect of 2 different methods of transepithelial corneal collagen cross-linking (CXL) on corneal histology and hysteresis. Methods: The right eyes of New Zealand white rabbits (n = 50) were treated using one of the 2 transepithelial CXL methods. The eyes were then divided into 2 groups: group 1, transepithelial CXL using continuous ultraviolet A (UVA); group 2, accelerated transepithelial CXL using pulsed UVA. Results:...
