BCVA and tomographic parameters depending on the three groups. Data presented as mean ± SD preoperatively and 12 and 24 months following corneal CXL. a) BCVA, b) astigmatism, c) Kmax, d) Kmin, e) MCT, f) CCT. Statistically significant group differences (*p < 0.05) were observed for BCVA (12 months and 24 months post-op) and astigmatism (24 months post-op)
