Preop vision a factor in BCVA change after cross-linking
SAN DIEGO — Corneal collagen cross-linking thwarted the progression of keratoconus and corneal ectasia in a majority of patients, and corneal flattening was sustained after 1 year, according to a study presented here.“We can say that cross-linking in most of the patients was very effective, that preop BCVA was a predictive factor for the change in BCVA in time, and also that the preop value of the average K was a predictive factor for change of keratometry in time,” Isabelle E.Y. Saelens, MD, said at the World Cornea Congress.
