囊袋张力环作为一种囊袋内填充装置，在白内障手术中起着重要的作用。囊袋张力环设计的初衷是维持囊袋的圆形轮廓、提高手术安全性，之后发现它在抑制后囊膜混浊与囊袋收缩、增强人工晶状体稳定性等方面亦有较好效果。经过近30a的改良，囊袋张力环衍生出多种类型，临床应用范围逐渐扩展，尤其是应用于复杂白内障手术，可以降低术中风险及提升术后效果。本文总结了囊袋张力环临床应用的植入时机、适应证和并发症，并对近年来囊袋张力环的临床应用进展进行简要综述。

[Abstract]
As an in-bag filling device, capsular tension ring(CTR)has played an important role in cataract surgery. Maintaining the circular contour of the capsular bag and improving the safety of surgery is the original intention of CTR design, and then it was found to have better effects in inhibiting posterior capsular opacity and capsular bag shrinkage, and enhancing the stability of intraocular lenses. After nearly 30a of improvement and development, CTR has been derived into a variety of types, and its clinical application has gradually expanded. In particular, CTR can be used in complex cataract surgery to reduce intraoperative risk and improve postoperative outcomes. In the present paper, the implantation timing, indications and complications of CTR were summarized, and the progress in clinical application in recent years was briefly reviewed.
