白内障术中矫正角膜散光的研究进展

Research progress of correcting corneal astigmatism in cataract surgery

散光矫正是屈光性白内障手术的必然要求,术中散光矫正问题日益受到重视。术前对角膜的屈光状态充分评估,科学合理设计手术切口,选择适宜手术方式,矫正术前存在的角膜散光,是解决白内障术后因散光导致视觉质量不佳的有效方法。目前白内障术中矫正散光的方法主要有角膜松解术和散光矫正型人工晶状体(Toric IOL)植入术。本文就白内障术中联合矫正角膜散光相关研究进行综述。

Astigmatism correction is the inevitable requirement of refractive cataract surgery,and the issues of astigmatism correction in surgery has been paid more and more attention.Adequate preoperative evaluation of corneal refractive status,scientific and reasonable design of surgical incision,and appropriate surgical methods,make better correction of preoperative corneal astigmatism which may effectively improve the poor post-operative visual quality caused by astigmatism after cataract surgery.At present,methods of combined corneal astigmatism correction in cataract surgery include keratotomy and Toric intraocular lens implantation.This article reviewed recent progress of correcting corneal astigmatism in cataract surgery.
