Bland-Altman plot of agreement between the predicted values of machine learning (ML) models and the modified vergence formula (MVF). a Bland-Altman plot of postoperative SE after NT-ICL implantation; b Bland-Altman plot of postoperative sphere after NT-ICL implantation; c Bland-Altman plot of postoperative sphere after TICL implantation; d Bland-Altman plot of postoperative sphere after TICL implantation. The mean difference (red) and 95% limits of agreement (mean difference − 1.96 SD, mean difference + 1.96 SD, black) are indicated by dotted lines. NT-ICL, non-toric implantable collamer lens; TICL, toric implantable collamer lens
