随着屈光性白内障手术的发展，散光矫正型人工晶状体(Toric IOL)作为一种功能性IOL已在临床上广泛应用，植入后能有效地矫正白内障患者术前的角膜散光，减少术后残余散光，获得更好的裸眼视力和视觉质量。轻微的Toric IOL偏心、倾斜和旋转不会引起患者明显的主观不适，但一定程度的偏心、倾斜和旋转反而增加散光和高阶像差，导致视力和视觉质量下降。本文根据相关国内外研究结果，结合基础和临床两个层面分析了Toric IOL的偏心、倾斜和旋转对视觉质量的影响，并对目前存在的问题和展望进行了讨论。

[Abstract]
With the development of refractive cataract surgery,Toric intraocular lens(Toric IOL)has been widely used as a functional IOL in the clinical practice. The implantation of Toric IOL in cataract patients can effectively correct preoperative corneal astigmatism and reduce postoperative residual astigmatism, thus obtaining better uncorrected visual acuity and visual quality. Mild decentration, tilt and rotation of Toric IOL do not cause significant subjective discomfort in patients. However, a certain degree of decentration, tilt and rotation of Toric IOL can increase astigmatism and higher-order aberration, resulting in decreased visual acuity and visual quality. Based on relevant results at home and abroad, this article reviewed the influence of the decentration, tilt and rotation of Toric IOL on visual quality at both basic and clinical levels and discussed the existing problems and prospects.
