Figure 1 Bland–Altman plots for the nine parameters measured by the Pentacam and Sirius. The mean difference is represented by the solid line and 95% limits of agreement (LoA) are presented by the dotted lines. (a) K1. (b) K2. (c) avgerage K. (d) Kmax. (e) Highest anterior elevation. (f) Highest posterior elevation. (g) Anterior best-fit sphere. (h) Posterior best-fit sphere. (i) Thinnest location pachymetry.
