白内障不同切口影响术后散光原因的分析

Analysis on the reason of impact on postoperative astigmatism of different incisions in cataract patients

随着白内障手术的日益完美,术后散光成为影响患者术后理想屈光状态的主要原因之一。目前最常使用的白内障手术方法仍是切口大小为3.2 mm的白内障超声乳化摘除联合人工晶体植入术,随着微小切口白内障手术的发展,术后散光相应减小。由于不同手术方式产生的术后散光不同,现通过文献回顾,综述不同切口影响白内障术后散光的原因并进行分析。

With the increasing progress of cataract surgery, the postoperative residual astigmatism has become one of the factors that influence the desirable refractive outcome for patients. At present, the most commonly used cataract extraction is also traditional phacoemulsification cataract surgery with incision size of 3.2 mm. With the progress of Micro-incision cataract surgery （MICS）, the postoperative residual astigmatism decreased. The different surgery induce different postoperative residual astigmatism. Through literature review, to analyze the causes of postoperative residual astigmatism by different incision cataract.
