Posterior capsule opacification remains a significant problem following cataract surgery. The aim of the study was to evaluate the incidence of symptomatic posterior capsule opacification requiring Nd:YAG capsulotomy in patients who underwent cataract extraction and implantation of the Rayner C-flex 570C intraocular lens (IOL) (Rayner Intraocular Lens, Ltd., Sussex, UK).
A retrospective study of 3,461 eyes that underwent cataract extraction and insertion of the Rayner C-flex IOL from January 2004 to December 2005. The cases that received Nd: YAG capsulotomies were evaluated.
Over a 24-month period, 3,461 Rayner C-flex IOLs were implanted. Nd:YAG capsulotomy was performed in 58 of these cases. The rate of Nd:YAG capsulotomy was 0.6% at 12 months and 1.7% at 24 months. The mean time to Nd:YAG capsulotomy was 9.3 months (range: 1.3 to 22.7 months). The follow-up period was 5.3 to 29.0 months.
The incidence of symptomatic posterior capsule opacification with the Rayner C-flex IOL is low.
白内障手术后后囊膜混浊仍然是一个重要问题。本研究的目的是评估在接受白内障摘除并植入Rayner C-flex 570C人工晶状体（IOL）（Rayner人工晶状体有限公司，英国苏塞克斯）的患者中，需要进行Nd:YAG囊膜切开术的有症状后囊膜混浊的发生率。
对2004年1月至2005年12月期间接受白内障摘除并植入Rayner C-flex IOL的3461只眼进行回顾性研究。对接受Nd:YAG囊膜切开术的病例进行评估。
在24个月的时间里，共植入了3461枚Rayner C-flex IOL。其中58例进行了Nd:YAG囊膜切开术。Nd:YAG囊膜切开术的发生率在12个月时为0.6%，在24个月时为1.7%。Nd:YAG囊膜切开术的平均时间为9.3个月（范围：1.3至22.7个月）。随访期为5.3至29.0个月。
Rayner C-flex IOL导致有症状后囊膜混浊的发生率较低。
