方法：选取2013-01/2015-12在本院眼科中心进行白内障超声乳化术患者39例40眼进行回顾性分析，所有患者均于术中同时植入囊袋张力环，随访6mo，观察患者的手术前后的视力变化、晶状体位置及并发症的发生情况。

结果：术后随访6mo，人工晶状体基本保持正位； 术前患者视力<0.1者19眼(48%)、0.1～0.3者21眼(52%)； 术后6mo，0.1～0.3者14眼(35%)，0.4～0.6者25眼(63%)，术后有1眼视力达到0.8。有13眼(33%)发生手术相关并发症，其中9眼(23%)发生角膜水肿， 2眼(5%)出现高眼压情况， 2眼(5%)出现玻璃体脱出。

结论：白内障超声乳化手术联合囊袋张力环植入治疗晶状体半脱位的效果可靠，安全性较好。

METHODS:Retrospective analysis was performed on 39 patients(40 eyes)who were treated with phacoemulsification in our hospital from Jan. 2013 to Dec. 2015. All patients were implanted the capsular tension ring at the same time, and the patients were followed up for 6 months, to observe the changes of visual acuity, the position of the lens and the occurrence of complications before and after operation.

RESULTS: At follow-up 6mo after operation, the intraocular lens was kept normal. Preoperative visual acuity(<0.1)had 19 eyes(48%), 0.1 to 0.3 range, and 21 eyes(52%); 6mo after surgery, patients with 0.1 to 0.3 range of vision in 14 eyes(35%)was significantly lower than preoperative; 0.4 to 0.6 range of vision in 25 eyes(63%)was significantly higher than that before surgery; 1 patients(1 eyes)visual acuity 0.8. A total of 13 eyes(33%)surgical complications, including 9 eyes(23%)had corneal edema, 2 eyes(5%)had high intraocular pressure, 2 eyes(5%)appeared prolapse of vitreous body.

CONCLUSION: Surgical treatment of subluxated lens treated with cataract phacoemulsification and capsular tension ring implantation is reliable and safety.
