Comparison of Color Light-Emitting Diode Corneal Topographer and Dual Rotating Scheimpflug–Placido Topographer

Figure 1

Bland–Altman plots showing the agreement between the posterior corneal index measurements from the 2 systems. The bold lines represent the mean difference between the 2 methods. The broken lines represent the 95% limits of agreement. (a) Normal group posterior simK, (b) refractive group posterior simK, (c) normal group posterior astigmatism magnitude, (d) refractive group posterior astigmatism magnitude, (e) normal group posterior J0, (f) refractive group posterior J0, (g) normal group posterior J45, and (h) refractive group posterior J45 (color LED, color light-emitting diode corneal topographer; DRSP, dual rotating Scheimpflug–Placido corneal topographer).
