Corneal Cross-Linking as a Treatment for Keratoconus: Four-Year Morphologic and Clinical Outcomes with Respect to Patient Age
Purpose:
To report the 4-year outcomes of corneal cross-linking (CXL) for progressive keratoconus in a population of different age groups.
Design:
Retrospective, single-center, nonrandomized clinical study.
Participants:
Four hundred consecutive eyes treated with corneal CXL for progressive keratoconus from April 2006 through April 2010.
Intervention:
After removal of the epithelium, the cornea was irrigated for 30 minutes with a solution of 0.1% riboflavin and 20% dextran, followed by irradiation with an ultraviolet A light of 3 mW/cm2 for 30 minutes.
