Rotational stability is key for optimizing postoperative visual outcomes because even a small degree of rotation of a toric intraocular lens (IOL) from its target axis can result in a significant reduction in astigmatic correction. This systematic review and meta-analysis evaluated the rotational stability of toric IOLs of different lens models and haptic designs. All published studies and clinical trials that investigate postoperative rotation of toric IOLs were searched and evaluated. Quality of studies was assessed using the Methodological Index for Nonrandomized Studies scale. A single-arm meta-analysis was performed in R4.3.1 software with subgroup analysis performed based on lens model and haptic design. 51 published studies of 4863 eyes were included in the meta-analysis. The pooled mean absolute rotation of all toric IOLs was 2.36 degrees (95% CI, 2.08-2.64). Postoperative rotation is dependent on many aspects of lens material and design. Modern commercially available toric IOLs exhibit exceptional rotational stability.
旋转稳定性对于优化术后视觉效果至关重要，因为即使是很小程度的散光人工晶状体（IOL）相对于目标轴的旋转，也可能导致散光矫正显著减少。本系统评价和荟萃分析评估了不同晶状体模型和襻设计的散光 IOL 的旋转稳定性。搜索并评估了所有研究和临床试验，以评估术后散光 IOL 的旋转。使用非随机研究方法学指数量表评估研究质量。在 R4.3.1 软件中进行了单臂荟萃分析，并根据晶状体模型和襻设计进行了亚组分析。荟萃分析纳入了 51 项 4863 只眼的已发表研究。所有散光 IOL 的平均绝对旋转为 2.36 度（95%CI，2.08-2.64）。术后旋转取决于镜片材料和设计的许多方面。现代市售的散光 IOL 具有出色的旋转稳定性。
