Time Course of Changes in Simulated Keratometry and Total Corneal Refractive Power after Corneal Collagen Cross-Linking for Progressive Keratoconus

Figure 3

Time course of central corneal thickness after corneal cross-linking (CXL). Multiple comparisons demonstrated no significant differences between measurements made before CXL and at 1, 3, 6, and 12 months after CXL. The results are expressed as median ± quartiles.
