方法：选择在我院眼科就诊的闭角型青光眼合并白内障、原发性房角关闭患者作为研究对象，给予超声乳化联合人工晶状体植入术治疗，观察治疗前后患眼的平均视力、平均眼压、平均散光以及术后出现的并发症。

结果：患眼平均视力由0.15±0.02恢复至0.48±0.13、平均眼压由23.29±4.83mmHg下降至18.34±2.41mmHg、散光程度由1.14±0.15DC降至0.53±0.06DC； 术后并发症发生率角膜水肿2.5%、后囊混浊3.4%、前房纤维素渗出5.1%。

结论：超声乳化能够有效的改善眼压、恢复视力，对于闭角型青光眼和原发性房角关闭具有积极的治疗意义。

METHODS: Angle-closure glaucoma patients with cataract and primary angle closure patients were collected as research objects and given phacoemulsification combined with intraocular lens implantation for treatment. Then the preoperative and postoperative mean value of visual acuity,intraocular pressure and astigmatism and postoperative complication of treated eyes were observed.

RESULTS: The average visual acuity of treated eyes recovered from(0.15±0.02)to(0.48±0.13); the average intraocular pressure was dropped from(23.29±4.83)mmHg to(18.34±2.31)mmHg; astigmatism was dropped from(1.14±0.15)DC to(0.53±0.06)DC. As to postoperative complications, the occurrence rate of corneal edema, posterior capsular opacification and fibrous exudation in anterior chamber was 2.5%, 3.4 and 5.1%, respectively.

CONCLUSION: Phacoemulsification can effectively improve intraocular pressure and visual acuity,which has positive therapeutic significances in treating angle-closure glaucoma and primary angle closure.
