超声乳化白内障吸除术联合人工晶状体植入术治疗闭角型青光眼的临床观察

目的:观察超声乳化白内障吸除术联合后房型折叠式人工晶状体植入术治疗急性闭角型青光眼合并白内障患者的临床疗效。方法:42例(42眼)急性闭角型青光眼合并白内障患者入院后均行超声乳化白内障吸除术联合后房型折叠式人工晶状体植入术,术后随访3mo。结果:术后最佳校正视力,较术前显著提高(P<0.05);患者术后3mo眼压平均为(13.5±3.2)mmHg,较术前用药前后眼压相比均明显下降(P<0.05);前房角镜检查发现术后前房角均有增宽,房角关闭及周边虹膜前粘连范围减小;中央前房深度为(3.12±0.46)mm,手术前后相比,差异有统计学意义(P<0.05)。结论:超声乳化白内障吸除术联合后房型折叠式人工晶状体植入术可有效降低眼压、提高视力,为急性闭角型青光眼同时合并白内障患者安全有效的治疗途径之一。

Effect of phacoemulsification with foldable posterior chamber intraocular lens implan-tation in management of acute angle-closure glaucoma

AIM:To study the clinical effect of phacoemulsification with foldable posterior chamber intraocular lens(PC-IOL)implantation in the management of acute angle-closure glaucoma(ACG)with cataract.METHODS:Phacoemulsification with foldable PC-IOL implantation was performed in 42 cases(42 eyes).The best corrected visual acuity(BCVA),intraocular pressure(IOP),anterior chamber depth(ACD)and anterior chamber angle width were measured and recorded preoperatively and at postoperative 1 day,1 week,1 month and 3 months.RESULTS:The mean IOP decreased significantly after surgery(P<0.05).The BCVA was significantly better after surgery(P<0.05).The angles examined by gonioscopy were wider after surgery,and the extent of any touch or adhesion between iris and trabecula reduced.The ACD increased after surgery significantly(P<0.05).CONCLUSION:Phacoemulsification with foldable PC-IOL implantation can substantially reduce IOP and improve visual acuity and can be one of the good alternatives in treatment of ACG with cataract.
