From 230 eyes implanted with 13.2 mm ICL, these were divided in modeling (n = 180) and evaluation group (n = 50). Two groups implanted with 12.6 mm and 13.7 mm (n = 50 each) were also used as evaluation. Anterior-segment optical coherence tomography was used preoperatively to perform anterior chamber biometry (angle-to-angle [ATA] distance, crystalline lens rise, anterior chamber depth [ACD], cornea sagittal depth, pupil diameter, nasal\/temporal TIA<jats:sub>750<\/jats:sub>); postoperatively for measuring the vault, pupil diameter and nasal\/temporal TIA<jats:sub>750<\/jats:sub>. Corneal curvature and horizontal visible iris diameter were measured using optical tomography. Bivariate correlation analysis was used to determine associations between preoperative and postoperative horizontal TIA<jats:sub>750<\/jats:sub> with anterior chamber biometry, ICL-related parameters and age. Finally, a multivariate linear regression model was constructed for predicting the postoperative TIA<jats:sub>750<\/jats:sub>.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>Horizontal TIA<jats:sub>750<\/jats:sub> reduced from 42.9 \u00b1 8.0 degrees preoperatively to 24.4 \u00b1 5.6 degrees postoperatively. Postoperative TIA<jats:sub>750<\/jats:sub> was positively correlated with the preoperative TIA<jats:sub>750<\/jats:sub>, cornea sagittal depth and ACD, and negatively associated with the vault. The main predictors of the postoperative TIA<jats:sub>750<\/jats:sub> were the preoperative parameters, TIA<jats:sub>750<\/jats:sub>, ICLsize \u2212 ATA and pupil diameter (adjusted-<jats:italic toggle=\"yes\">R<\/jats:italic>\n                                 <jats:sup>2<\/jats:sup> = 0.39).
