Group A included 37 patients (37 eyes) with the ATTORBI 709\u202fM plate-haptic design, while Group B comprised 42 patients (42 eyes) with the PY-60\u202fAD C-loop design. SS-OCT examinations were performed both before and one month after cataract surgery. A customized CNN algorithm was developed to generate data for IOL tilt and decentration, using the corneal vertex as a reference.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      This study included 79 patients (79 eyes). Before surgery, there were no statistically significant differences in ocular parameters between the two groups (all\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;gt;\u202f0.05). Significant difference in IOL decentration was observed (Group A &amp;amp; Group B: 0.16\u202f\u00b1\u202f0.08\u202fmm &amp;amp; 0.42\u202f\u00b1\u202f0.28\u202fmm,\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.001).

Both groups displayed a predominant inferotemporal tilt of the crystalline lens and IOL, but decentration did not show a distinct distribution pattern. Multivariate linear regression confirmed a correlation between IOL tilt in both groups and crystalline lens tilt (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.003).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The plate-haptic design IOL shows less decentration than the C-loop design.
