散光是屈光不正的常见类型，由角膜或晶状体非对称曲率引起。在屈光性白内障手术时代，角膜散光对白内障患者术后的视觉质量影响很大。散光人工晶状体(Toric IOL)作为矫正白内障合并散光的重要手段，可矫正大范围的散光度数，显著提高患者术后的裸眼视力。但其术后稳定性可直接影响患者术后的视觉质量。文章就Toric IOL稳定性的影响因素及改进策略展开综述，旨在为临床上Toric IOL的选择和未来IOL的研究方向提供参考。

[Abstract]
Astigmatism, a common form of refractive error, results from an asymmetric curvature of the anterior corneal surface or the lens. In the context of refractive cataract surgery, corneal astigmatism has a substantial impact on postoperative visual outcomes. Toric intraocular lenses(Toric IOL)have become a critical option for managing cataracts accompanied by astigmatism, effectively correcting a broad spectrum of astigmatic errors and significantly improving postoperative uncorrected visual acuity. However, the rotational stability of Toric IOL following implantation is a key determinant of final visual quality. This review systematically examines factors influencing the postoperative stability of Toric IOL and discusses potential strategies for enhancement, with the aim of providing evidence-based guidance for clinical Toric IOL selection and future developments in IOL design.
