Background <p>Rotational stability is a critical determinant of the refractive performance of toric intraocular lenses (IOLs), as even small degrees of postoperative rotation may compromise astigmatic correction. This study aimed to compare the rotational stability of two toric IOLs with different designs.</p> Methods <p>A retrospective comparative study was conducted including eyes that underwent cataract surgery with implantation of either a monofocal toric Ankoris IOL or a TECNIS ZCT toric IOL. Postoperative IOL rotation was evaluated at 1&#xa0;day, 1 week, and 1 month after surgery. Rotational stability was assessed using the absolute value of rotation, regardless of direction. Secondary outcomes included the proportion of eyes with clinically significant rotation (&gt; 10°) and the need for surgical repositioning. Statistical analyses were performed according to data distribution.</p> Results <p>A total of 61 eyes were included, with 31 eyes in the Ankoris group and 30 eyes in the TECNIS ZCT group. At 1 month postoperatively, the Ankoris group showed a significantly greater absolute rotation compared with the TECNIS ZCT group (median 4° [IQR 3–8] vs. 3° [IQR 2–3], <i>p</i> = 0.047). Both IOLs demonstrated a tendency toward progressive stabilization over time; however, the TECNIS ZCT lens exhibited lower rotational variability at all evaluated time points. The proportion of eyes with rotation greater than 10° was low in both groups, with no statistically significant difference. Surgical repositioning was required in two eyes (6.5%) in the Ankoris group and in none of the TECNIS ZCT group (<i>p</i> = 0.49).</p> Conclusions <p>Both toric IOLs demonstrated clinically acceptable rotational stability during the first postoperative month. Among eyes demonstrating measurable postoperative rotation, the TECNIS ZCT lens exhibited lower rotational magnitude and less variability compared with the Ankoris lens, which may be clinically relevant when selecting toric IOLs for astigmatism correction.</p>
