Abstract: INTRODUCTION: This study evaluated the rotational stability of three toric intraocular lens (TIOL) platforms in patients undergoing repositioning surgery. METHODS: This comparative retrospective study enrolled eyes that underwent cataract surgery and implanted with an AcrySof, AT TORBI/LISA, or TECNIS TIOL. Patients who experienced TIOL misalignment ≥10° postoperatively and underwent repositioning surgery were included. The incidence of repositioning surgery after cataract surgery and the misalignment degree before and after repositioning surgery of the three TIOL platforms were mainly compared. RESULTS: Of the 2,598 eyes implanted with TIOLs, 56 eyes (2.156%) underwent repositioning. The repositioning rates for the AcrySof, AT TORBI/LISA, and TECNIS platforms were 0.848% (10/1,179), 2.935% (28/954), and 3.871% (18/465), respectively, showing significant differences (p < 0.001). Misalignment degrees before repositioning surgery for the AcrySof, AT TORBI/LISA, and TECNIS TIOLs were 27.90 ± 15.74°, 60.79 ± 18.79°, and 31.61 ± 20.84°, respectively (p < 0.001). AT TORBI/LISA platform had a significantly greater misalignment degree compared to AcrySof (difference: 32.89°, p < 0.001) and TECNIS platforms (difference: 29.18°, p < 0.001). There was no significant difference between AcrySof and TECNIS (difference: 3.71°, p = 0.629). After repositioning, the AT TORBI/LISA platform showed significantly higher misalignment degrees compared to AcrySof and TECNIS (difference: 6.63°; 5.49°, p = 0.009). CONCLUSION: AcrySof TIOLs had a lower incidence of repositioning surgery compared with AT TORBI/LISA and TECNIS, while AT TORBI/LISA TIOLs exhibited a higher degree of axis misalignment both before and after repositioning.
