The objective of this study was to compare the rotational stability of C-haptic PanOptix Toric (Alcon) and plate haptic AT Lisa Toric (Carl Zeiss Meditec) intraocular lenses (IOLs) using the iTrace system. This retrospective study involved 40 patients who underwent trifocal toric intraocular lens (IOL) implantation, either with the PanOptix Toric IOL (Group 1) or the AT Lisa Toric IOL (Group 2). Rotational stability was assessed at the 3-month postoperative visit using the iTrace Surgical Workstation (Tracey Technologies Corp., Houston, TX, USA) after pupil dilation. Group 1 comprised 20 patients, and Group 2 comprised 20 patients. The groups exhibited comparable preoperative characteristics, including age, sex, preoperative uncorrected and best-corrected distance visual acuity (UDVA and BDVA), spherical and cylindrical powers, axial length (AL), and corneal astigmatism (all p > 0.05). No statistically significant differences were observed between the groups in best-corrected visual acuity (BCVA), spherical, or cylindrical refractive errors at the three-month postoperative assessment (p > 0.05 for each parameter). The rotation angle, as measured by iTrace following pupil dilation, was 9.30 ± 10.84 degrees in Group 1 and 11.45 ± 8.76 degrees in Group 2 (p = 0.495). The data demonstrate that trifocal toric IOLs with C-haptic and plate-haptic designs have similar rotational stability in individuals with comparable biometric data.
