目的：通过对比钕：YAG （Nd:YAG）激光晶状体切除术后白内障后囊膜混浊的发生率，评价AcrySof(R)和Stabibag(R)两种不同的人工晶状体植入术后白内障后囊膜混浊的发生率。方法：回顾性分析1999年1年间596例（705眼）采用AcrySof （n = 335）或Stabibag （n = 370）人工晶状体行超声乳化术及后房型人工晶状体植入术的临床资料。伴有继发性白内障、联合手术或手术并发症（如囊撕裂）的眼睛被排除在研究之外。记录受试者的年龄、性别、术者（2名）、Nd:YAG激光囊切开术时间。结果：两组患者平均随访23个月。两组人工晶状体在性别分布和手术医师方面无统计学差异。AcrySof组的平均年龄为77.0岁，而Stabibag组的平均年龄为79.2岁（p = 0.001）。Stabibag组7.6%的患者进行了Nd:YAG激光囊膜切开术，而AcrySof组为2.7%（即显著高于对照组）（p = 0.004）。生存分析表明，年龄和人工晶状体的类型是唯一独立的预测发生率的囊切除术。结论：本研究表明，与AcrySof人工晶状体相比，Stabibag人工晶状体术后后囊膜混浊的发生率明显高于AcrySof。
Purpose: To evaluate the incidence of posterior capsule opacification after implantation of two different intraocular lenses (IOLs), AcrySof(R) and Stabibag(R), by comparing the neodymium:YAG (Nd:YAG) laser capsulotomy rates.Methods: The medical records of 596 patients (705 eyes) who underwent phacoemulsification and posterior chamber IOL implantation using either AcrySof (n = 335) or Stabibag (n = 370) IOLs during a 1-year (1999) period were reviewed. Eyes with secondary cataract, combined procedures or operative complications, such as capsule tears, were excluded from the study. The subjects' age, sex, surgeon (two surgeons), and time for Nd:YAG laser capsulotomy were recorded.Results: The mean follow-up was 23 months in both IOL groups. There were no statistically significant differences within the two IOL groups regarding sex distribution or surgeon. The mean age in the AcrySof group was 77.0 years compared to 79.2 years in the Stabibag group (p = 0.001). Nd:YAG laser capsulotomy was performed in 7.6% of patients in the Stabibag group compared to 2.7% in the AcrySof group (i.e. at a significantly higher rate) (p = 0.004). Survival analyses demonstrated that age and type of IOL were the only independent predictors of the incidence of capsulotomy.Conclusions: This study shows that the frequency of eyes with posterior capsule opacification needing capsulotomy was significantly higher in eyes with Stabibag IOLs compared to eyes with AcrySof IOLs.
