Corneal cross-linking halted the occurrence of ectasia progression after LASIK and PRK while improving corrected distance visual acuity and maximum keratometry readings, according to a study.

Twenty-six eyes of 26 patients were included in the retrospective study; 23 eyes experienced ectasia after LASIK and three eyes experienced ectasia after PRK. Mean patient age was 35 years. Patients were followed up for a mean of 25 months.

Mean corrected distance visual acuity improved from 0.5 preoperatively to 0.3 postoperatively; the gain was statistically significant (P < .001).

The mean keratometry readings decreased from 52.8 D preoperatively to 50.9 D postoperatively, which was also statistically significant (P < .001).

The minimum radius of curvature significantly increased after cross-linking; however, the index of surface variance, the index of vertical asymmetry, the keratoconus index and the central keratoconus index were significantly reduced (P = .03, P = .04, P = .03 and P = .016, respectively).
