了解白内障超声乳化术治疗急性闭角型青光眼合并白内障的有效性。 方法:对2006-03-01/2010-10-31收治的急性闭角型青光眼合并白内障患者47例51眼，眼压稳定后行超声乳化联合人工晶状体植入术，术后均随访1~3a。 结果:术后47例51眼中44例48眼眼压下降，术前眼压22.98±3.22mmHg，术后眼压13.24±3.17mmHg(P<005)，45例49眼视力较术前明显提高(P<0.05)。47例51眼术后前房深度加深，由术前1.542±0.314mm转为术后3.157±0.243mm(P<0.05)。 结论:白内障超声乳化术可以使急性闭角型青光眼前房加深，不同程度地开放已关闭的房角，改善周边窄房角的解剖状态，降低瞳孔阻滞后周边前房关闭的可能性，可以使升高的眼压下降，提高视力，是闭角型青光眼合并白内障患者安全有效的治疗途径。

To evaluate the efficacy and safety of phacoemulsification for acute angle-closure glaucoma combined with cataract. METHODS：An uncontrolled retrospective clinical study．Fifty-one eyes of 47 cases from 2006 to 2010 were acute angle-closure glaucoma combined with cataract. Phacoemulsification combined with intraocular lens implantation surgery was done after intraocular pressure was stable. The follow-up time was 1 year-3 years. RESULTS：Intraocular pressure (IOP) decreased after operation in 44 cases (48 eyes) in 47 cases (51 eyes). Preoperative IOP was 22.98±3.22mmHg, while postoperative IOP was 13.24±3.17mmHg(P<0.05). Visual acuity of 49 eyes improved significantly (P<0.05). The anterior chamber was deepened from the preoperative 1.542±0.314mm to postoperative 3.157±0.243mm (P<0.05). CONCLUSION：Phacoemulsification combined with intraocular lens implantation surgery is a safe and effective approach for the treatment of acute angle-closure glaucoma combined with cataract．A multi-center randomized controlled clinical study is needed to evaluate the long-time safety and efficacy of phacoemulsification for acute angle-closure glaucoma combined with cataract．Phacoemulsification can deepen the anterior chamber, partly reopen the closed peripheral anterior chamber angle，decrease the possibility of closure of the peripheral anterior chamber angle, make the elevated IOP drop, and improve eyesight.
