Cross-linking appears to halt progression of keratoconus for at least 7 years
Corneal collagen cross-linking improved visual acuity and prevented the progression of keratoconus for up to 7 years, according to a long-term study investigating the procedure, with no serious complications and no eyes requiring re-treatment.“All eyes were stable 7 years following cross-linking, and between 1 and 5 years, there were continued improvements in corneal shape with K-max reduced and coma improved. Importantly, there were no sight-threatening complications out to 7 to 8 years,” David P.S. O’Brart, MD, FRCS, FRCOphth, the corresponding author, told Ocular Surgery News.
