Phacoemulsification combined with intraocular lens(IOL)implantation is currently one of effective methods for treating cataracts. As cataract surgery technology has evolved, traditional cataract surgery has shifted from vision surgery to refractive surgery. The Toric IOL can significantly reduce corneal astigmatism and enhance patients' postoperative visual effects. However, the corrective impact of Toric IOL is influenced by numerous factors, including the accuracy of preoperative biometric measurements, selection of appropriate Toric IOL calculation formulas, the precision of implantation axis, surgical incision design, and rotational stability of the Toric IOL. This article will review the factors that influence the Toric IOL's effect on corneal astigmatism.
