超声乳化术治疗小梁切除术后并发白内障的临床观察

目的观察超声乳化白内障吸出术联合后房型人工晶状体植入术治疗小梁切除术后并发白内障的临床疗效。方法回顾性分析小梁切除术后并发白内障患者21例(22只眼),行透明角膜切口晶状体超声乳化吸除联合后房型人工晶状体植入术。随机选取同期单纯老年性白内障50例作对照,随访1个月至1年,对比术前、术后视力,观察术后角膜内皮细胞数量、前房深度、前房角宽度和眼压变化。结果术后视力均有不同程度提高;22只眼术后眼压均控制正常,与对照组相比差异无统计学意义(P>0.05);术后角膜内皮细胞丢失数(320±84)个/mm2,对照组为(338±78)个/mm2;两者差异无统计学意义(P>0.05);术前前房深度平均(2.14±0.10)mm,术后平均(3.30±0.28)mm,差异有统计学意义(P<0.05);术后前房角比术前明显变宽。结论超声乳化术治疗小梁切除术后并发白内障手术安全、疗效可靠。

Clinical effect of phacoemulsification on patients with complicated cataract after trabeculectomy

Objective To evaluate the therapeutic effect of phacoemulsification combined with posterior chamber intraocular lens implantation on cataract after trabeculeetomy. Methods Twenty-one patients （22 eyes） with cataract after trabeculeetomy （experimental group） were exerted with phacoemulcifieation combined with posterior chamber intraocular lens implantation. Fifty patients with senile cataract received the same operation and were chosen randomly as the control group. All individuals were followed up for 1 month to 1 year. The pre-and postoperative visual acuity, endothelial cells, anterior chamber depth, anterior chamber angle width and intraocular pressure （IOP） was observed. Results The visual acuity improved in all eyes after the operation. The IOPs in 22 eyes were all controlled to normal, with no significant difference compared with those in the control group（P 〉0.05 ）. The endothelium cell loss was 320±84/mm^2 in the experimental group and 338±78/mm^2 in the control group, with no significant difference between them （P 〉 0.05 ）. The anterior chamber was significantly deepened after the operation with the average depth increasing from （2.14±0.10） mm to （ 3.30±0.28 ） mm （ P 〈 0.05 ）. The anterior chamber angle was widened significantly. Conclusions Phacoeniulsification combined with posterior chamber intraocular lens implantation could be safe and effective for patients with cataract after trabeculeetomy. （ Chin J Ophthalmol and Otorhinolaryngol,2011,11：35-37）
