Optical Coherence Tomography and Confocal Microscopy Following Three Different Protocols of Corneal Collagen-Crosslinking in Keratoconus

Abstract

Iontophoresis was associated with weaker damage of corneal sub-basal nerves and anterior keratocytes compared to conventional procedures, but the demarcation line was present in less than 50% of cases and was more superficial than with the traditional procedure.
