近年来，高度近视合并白内障的发病率逐渐升高，高度近视眼特殊的解剖构造及病变性质，使得此类患者治疗难度及各类并发症远高于普通白内障手术。随着设计和材料的不断进步，囊袋张力环(CTR)的适应证逐渐扩展，尤其对于高度近视患者而言，可以维持人工晶状体位置的稳定，辅助悬韧带松弛部位，抑制术后残留的晶状体上皮细胞的迁移和增生，改善患者视觉质量以及降低视网膜脱离的发生率。本文就CTR的历史发展背景、临床使用情况以及在高度近视合并白内障中的应用效果等进行综述。

In recent years, the incidence of high myopia complicated with cataract shows a gradual upward trend. Due to the special anatomical structure and lesion nature of high myopia, the difficulty and various complications of such patients are much higher than those of ordinary cataract surgery. With the continuous advancement of design and materials, the indications for capsular tension ring(CTR)have gradually expanded. Especially for patients with high myopia,it can maintain the stability of intraocular lens position, assist the relaxation of the suspensory ligament, inhibit the migration and proliferation of residual lens epithelial cells after surgery, improve the visual quality of patients and reduce the incidence of retinal detachment. This paper reviewed the history of CTR, its clinical application, and the effect of CTR on high myopia complicated with cataract.
