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.
