摘　　要：目的探讨白内障手术中晶状体后囊膜破裂的相关因素。方法选取2014年2月-2015年4月贵州省妇幼保健院收治的白内障手术中晶状体后囊膜破裂患者36例(37眼),按照1:4的比例选取白内障手术中晶状体后囊膜未破裂患者144例(147眼),比较两组患者术后视力,对晶状体后囊膜破裂的相关因素进行分析。结果破裂组36例,37眼,术后视力<0.1的1例,0.1~0.3的5例,0.4~0.8的19例,≥0.9的12例;未破裂组144例,147眼,术后视力<0.1的1例,0.1~0.3的7例,0.4~0.8的68例,≥0.9的71例。两组(破裂组和未破裂组)患者Emery核分级、术前视力、合并高血压、植入人工晶体、玻璃体积血差异均具有统计学意义(P<0.05)。对单因素分析中有统计学意义的数据进行多因素Logistic回归分析,结果显示术前视力、玻璃体积血是影响白内障手术中晶状体后囊膜破裂的独立危险因素(P<0.05)。结论白内障手术中晶状体后囊膜破裂能够降低患者视力,其中术前视力、玻璃体积血是影响晶状体后囊膜破裂的独立危险因素。Objective To explore the factors related to rupture of posterior capsule of the lens during cataract surgery. Methods This study selected 36 patients （37 eyes） with posterior capsule rupture of the lens during cataract surgery treated in our hospital from February 2014 to April 2015. In accordance with the ratio of 1： 4, 144 cases of unruptured posterior capsule （147 eyes） were selected, Visual acuity was compared between the two groups of patients, and the relevant factors of posterior capsular rupture were analyzed. Results In the rupture group, 1 case had visual acuity 〈0.1, 5 cases had visual acuity of 0.1-0.3, 19 cases had visual acuity of 0.4-0.8, 12 cases had visual acuity≥ 0.9. In the unruptured group, 1 case had visual acuity 〈 0.1, 7 cases had visual acuity of 0.1-0.3, 68 cases had visual acuity of 0.4-0.8, 71 cases had visual acuity I〉0.9. There were significant differences in Emery nuclear grade, preoperative visual acuity, hypertension, intraocular lens implantation and vitreous hemorrhage between the two groups （P 〈 0.05）. Multivariate logistic regression analysis showed that preoperative visual acuity and vitreous hemorrhage were the independent risk factors for posterior capsule rupture of the lens during cataract surgery （P 〈 0.05）. Conclusions Posterior capsule rupture of the lens during cataract surgery can reduce visual acuity. Preoperative visual acuity and vitreous hemorrhage are the independent risk factors for posterior capsule rupture of the lens.
