Standard cross-linking versus photorefractive keratectomy combined with accelerated cross-linking for keratoconus management: a comparative study.

Refractive outcomes analysis In group A, there was a statistically highly significant reduction in the myopic component that was reduced from 3.21 ± 1.09 to 1.17 ± 0.73 D (mean ± SD) postoperatively at the end of the 24th month of follow‐up period (p value <0.001) ( Tables 3 and 4 ) .

These outcomes in group A could be attributed to the fact that the standard CXL affects all corneal meridians symmetrically so that it had a great influence in the postoperative sphere reduction and almost insignificant influence in the postoperative cylinder reduction.
