目的：回顾性分析超声乳化术后Nd：YAG激光后囊膜切开术的累积概率，并评估其危险因素。日本神奈川安藤眼科诊所：方法：在3997只接受超声乳化术和连续环形撕囊术的眼睛中，通过Kaplan-Meier生存分析计算后囊切开术的累积概率，并使用考克斯比例风险回归模型分析风险因素。测试的变量是性别;老化;白内障的类型;术前最佳矫正视力（BCVA）;糖尿病、糖尿病性视网膜病变或视网膜色素变性的存在;人工透镜（IOL）的类型;以及进行手术的年份。人工晶状体分为3件式聚甲基丙烯酸甲酯（PMMA），1件式PMMA，3件式硅胶，丙烯酸folded.Results：白内障手术后的囊切开术的累积概率为1.95%，18.50%，和32.70%，在1，3，5年，分别。阳性风险因素包括术前BCVA较好（P = .0005;风险比[RR]，1.7; 95%置信区间[CI]，1.3-2.5）和视网膜色素变性（P
Purpose: To retrospectively analyze the cumulative probability of neodymium:YAG (Nd:YAG) laser posterior capsulotomy after phacoemulsification and to evaluate the risk factors.Setting. Ando Eye Clinic, Kanagawa, Japan.Methods: In 3997 eyes that had phacoemulsification with an intact continuous curvilinear capsulorhexis, the cumulative probability of posterior capsulotomy was computed by Kaplan-Meier survival analysis and risk factors were analyzed using the Cox proportional hazards regression model. The variables tested were sex; age; type of cataract; preoperative best corrected visual acuity (BCVA); presence of diabetes mellitus, diabetic retinopathy, or retinitis pigmentosa; type of intraocular lens (IOL); and the year the operation was performed. The IOLs were categorized as 3-piece poly(methyl methacrylate) (PMMA), 1-piece PMMA, 3-piece silicone, and acrylic foldable.Results: The cumulative probability of capsulotomy after cataract surgery was 1.95%, 18.50%, and 32.70% at 1, 3, and 5 years, respectively. Positive risk factors included a better preoperative BCVA (P = .0005; risk ratio [RR], 1.7; 95% confidence interval [CI], 1.3-2.5) and the presence of retinitis pigmentosa (P
