Corneal cross-linking in keratoconus. Results from a seven-years follow-up

Abstract

We assessed the eff ects of corneal cross-linking in a young patient with progressive keratoconus over a seven-year period. Th is was a retrospective study of a 16-year-old patient with progressive keratoconus after epi-off corneal cross-linking (CXL). Uncorrected visual acuity, best-corrected visual acuity, refraction, maximum keratometry, mean keratometry and pre-treatment of higher order aberrations were assessed every month and then every two years after CXL. Results showed an interruption in keratoconus progression, improvement in best-corrected visual acuity, and a decrease in keratometry, as well as an improvement in higher order aberrations, in both the medium and long term throughout the follow-up period. In conclusion, corneal CXL was found to be eff ective in interrupting keratoconus progression over a long follow-up period.
