Abstract：
To identify the risk factors predisposing posterior capsule rupture (PCR) during mature cataract surgery.
A total of 1302 consecutive mature cataract cases were included in this retrospective study. A detailed examination was performed for each patient and risk factors including age, gender, systemic diseases, ocular comorbidities, surgeon, and surgery method were recorded. Cases with PCR during surgery were classified as complicated. Multivariate logistic regression analysis with a generalized estimating equations method was applied for statistical analysis.
The overall rate of PCR was 7.30% (n=95 eyes). After adjusting for confounders, factors that remained significant on multivariate analysis were strabismus (odds ratio [OR]: 5.70, 95% confidence interval [CI]: 2.17-14.97; P < 0.001), phacodonesis (OR: 4.62, 95% CI: 2.59-8.22; P < 0.001), history of trauma (OR: 4.46, 95% CI: 1.64-12.12; P = 0.003), surgery method (extracapsular cataract extraction/phacoemulsification) (OR: 2.61, 95% CI: 1.60-4.26; P < 0.001), and pseudoexfoliation (OR: 1.94, 95% CI: 1.20-3.16; P = 0. 007).
Strabismus, phacodonesis, history of trauma, extracapsular cataract extraction method, and pseudoexfoliation were found to be important risk factors for developing PCR. Appropriate preoperative and perioperative precautions for these higher-risk cases can reduce complications.

摘要：
UASSIGNED：确定在成熟白内障手术中诱发后囊破裂（PCR）的危险因素。
UNASSIGNED：这项回顾性研究共纳入了1302例连续的成熟白内障病例。对每位患者进行了详细的检查，包括年龄在内的危险因素，性别,全身性疾病,眼部合并症，外科医生,并记录手术方法。手术期间进行PCR的病例被归类为复杂病例。采用广义估计方程方法进行多变量逻辑回归分析进行统计分析。
UNASSIGNED:总的PCR率为7.30%(n=95只眼)。在调整了混杂因素后，在多变量分析中保持显著的因素是斜视(比值比[OR]:5.70,95%置信区间[CI]:2.17-14.97;P<0.001),牙列(OR:4.62,95%CI:2.59-8.22;P<0.001),外伤史(OR:4.46,95%CI:1.64-12.12;P=0.003),手术方式(囊外白内障摘除/超声乳化)(OR:2.61,95%CI:1.60-4.26;P<0.001),和假性剥脱（OR：1.94，95％CI：1.20-3.16；P=0。007）。
未经授权：斜视，牙列,外伤史,白内障囊外摘除术,发现假性剥脱是发展PCR的重要危险因素。对这些高危病例采取适当的术前和围手术期预防措施可以减少并发症。
