改良超声乳化联合小梁切除术的临床应用

目的探讨改良超声乳化联合小梁切除术治疗青光眼合并白内障的可行性及临床效果。方法对21例(21眼)青光眼合并白内障患者施行改良白内障超声乳化联合巩膜隧道切口内的小梁切除术,术后随访观察视力、眼压、滤过泡、人工晶状体位置等情况。结果术后平均随访1年,18眼术后视力均有不同程度提高。指数者2眼,<0.1者1眼,0.1～0.3者5眼,0.3以上者13眼,术后眼压均在正常范围,平均眼压为(12.32±4.06)mmHg(1mmHg=0.133kPa)。结论改良白内障超声乳化及人工晶状体植入联合巩膜隧道内小梁切除术,可达到降眼压和提高视力的双重效果,是青光眼合并白内障较好的手术方法之一。

Clinical application of modified phacotrabeculectomy

Objective To evaluate the feasibility and clinical effect of modified phacotrabeculectomy on patients with glaucoma and cataract. Methods Twenty-one eyes of 21 patients with glaucoma and cataract were treated with phacotrabeeulectomy under a modified seleral tunnel incision. Visual acuity, intraocular pressure, filtering bleb and the position of intraocular lens were observed after the surgery. Results The patients were followed up for one year average- ly. Eighteen patients achieved better visual acuity （finger count in 2 eyes, 〈 0.1 in 1 eye, 0.1 to 0.3 in 5 eyes and 〈 0.3 in 13 eyes） and the mean postoperative intraocular pressure was 12.32 ±4.06 nun Hg （1 mm Hg =0. 133 kPa）. Conclusions Phacotrabeculectomy and intraocular lens implantation was effective in reducing intraocullar pressure and improving visual acuity in patients with glaucoma and cataract.
