Fig. 2

Posterior corneal elevation changes at the 6-month and 5-year follow-up. a. PCE change; b. PTE change; c. PME change. PCE = posterior central elevation; PTE = posterior corneal surface at thinnest point; PME = posterior corneal mean elevation; NS = not significant. P values were adjusted for preoperative spherical equivalent in mixed effect model. P values less than 0.05 were considered statistically significant
