散光型人工晶状体旋转稳定性的影响因素

The influence factors of rotational stability of Toric introcular lens

散光型人工晶状体(Toric IOL)是解决白内障患者较大角膜散光的主要方式,其旋转稳定性是决定其术后矫正效果的主要因素之一。Toric IOL轴位旋转受术前标记、术中操作、自身旋转、囊袋纤维化及手术方式等多种因素影响,只有充分了解其影响因素,针对患者个体特性,才能更好地减少术后旋转的发生。

The Toric introcular lens(IOL)is the main way to solve larger corneal astigmatism in cataract patients,and its rotational stability is one of the main factors determining its postoperative corrective effect.The axial rotation of Toric IOLs is affected by various factors such as preoperative marking,intraoperative alignment,self-rotation,capsular bag fibrosis,and surgical methods.Only by fully understanding the effect factors and targeting the individual characteristics of the patient can we better minimize the occurrence of postoperative rotation.
