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

Figure 2

Time courses of the simulated keratometry (Sim K) and total corneal refractive power (TCRP) after corneal cross-linking (CXL). The Sim K was significantly larger than the TCRP before CXL and at 1, 3, 6, and 12 months after CXL. The results are expressed as median ± quartiles. p<0.001.
