Bland-Altman analysis showing the distribution of the corneal astigmatism differences on the -axis and the average of the instrument readings on the -axis. IOL Master and Galilei, above (mean : +0.016 ± 0.249 D, with 95% limits of agreement between −0.482 and +0.514); IOL Master and WAM 5500, middle (mean : −0.061 ± 0.265 D, with 95% limits of agreement between −0.591 and +0.469); Galilei and WAM 5500, below (mean : −0.078 ± 0.292 D, with 95% limits of agreement between −0.662 and +0.506).
