目的：探讨晶状体囊袋张力环(capsular tension ring，CTR)联合虹膜拉钩在白内障合并晶状体不全脱位手术中的应用。
方法：对27例27眼合并晶状体不全脱位的白内障患者行白内障超声乳化手术，术中植入CTR联合虹膜拉钩固定前囊孔完成手术。观察术后视力、眼压、前房及人工晶状体位置等情况。
结果：患者25例25眼按照预定手术方案顺利完成手术； 2例2眼出现后囊破裂、玻璃体脱出： 其中1例睫状沟植入人工晶状状体，另1例植入前房型人工晶状体。所有病例视力均有不同程度提高，无严重并发症发生。
结论：在超声乳化治疗合并晶状体不全脱位的白内障手术中，运用CTR联合虹膜拉钩能提高手术的可操作性和安全性，减少手术并发症。

[Abstract]
AIM: To discuss the application of capsular tension ring(CTR)combined with iris hook in treatment of cataract with dislocated lens.
METHODS: Twenty-seven patients with 27 cataract-infected eyes combined with lens subluxation were treated phacoemulsification cataract surgery. With iris hook fixing capsular hole, CTR was implanted. The operation methods, postoperative vision, intraocular pressure, anterior chamber and intraocular lens location were analyzed.
RESULTS: The operations were successfully completed for 25 patients with 25 cataract-infected eyes. The posterior capsule rupture and vitreous prolapse happened for the other 2 cases with 2 eyes. Between the 2 cases, 1 received ciliary sulcus implantation and the other anterior chamber intraocular lens implantation. The patients' vision was improved more or less. No serious complications happened.
CONCLUSION: The application of CTR combined with iris hook in the treatment of cataract with lens dislocation can improve the procedure's operability and security, and reduce operation complications.
