Official title
Randomized Study of Safety and Effectiveness of Corneal Collagen Crosslinking Using Two Different Riboflavin Administration Protocols
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Corneal collagen crosslinking (CXL) has been demonstrated as an effective method of reducing progression of both keratoconus and corneal ectasia after surgery, as well as possibly decreasing the steepness of the cornea in these pathologies. Transepithelial crosslinking in which the epithelium is not removed has been proposed to offer a number of advantages over traditional crosslinking including an increased safety profile by reducing the risk for infection and scarring, faster visual recovery and improved patient comfort in the early postoperative healing period.
