白内障超声乳化与现代囊外摘除治疗白内障的对比分析

目的 :比较白内障超声乳化 (phacoemusificationaspiration ,PHACO)与现代囊外摘除 (extracapsularcataractextraction ,ECCE)治疗白内障的优缺点。方法 :采用回顾性的分析方法 ,对我院从 1996年至 1999年 35 0例(378只眼 )白内障患者中 ,其中 2 0 4眼进行了白内障超声乳化摘除联合人工晶植入 ,174眼进行了白内障现代囊外摘除与后房型人工晶体植入 ,对术后视力、角膜散光情况及术中术后主要并发症进行对比分析 ,经统计学处理 ,比较两者的差异。结果 :术后裸眼视力≥ 4.6者PHACO组占 86 .8% ,囊外摘除术组占 76 .9% ,角膜散光PHACO组平均为 - 1.5 0± 0 .5 ,ECCE组平均为 - 3.0± 0 .5 ,两者差异具有统计学意义。术中及术后早期并发症主要有后囊膜破裂、虹膜损伤、角膜水肿等。结论 :PHACO手术较ECCE手术具有较小的切口、较低的角膜散光值及获得较好视功能等特点 ,值得临床推广应用。

Comparison of Phacoemusification Aspiration and Extracapusular Cataract Extraction in the Treatment of Cataract

To compare the effects of phacoemusification aspiration (PHACO) and extracapsular cataract extraction(ECCE)in the treatment of cataract. Methods: From 1996 to 1999,350 patients(378 eyes) underwent cataract surgery in which 204 eyes underwent PHACO and 174 eyes underwent ECCE. In this retrospective study,the vision,astigmatism and the main complications after the operations were compared between two groups. The non-parametric test and Mann-Whitely U test were used in the statistical analysis. Results: 86.8% of the eyes treated in the PHACO group and 76.9% in the ECCE group had the visual acuity above 4.6. The average value of astigmatism was -1.5±0.5 (Mean±SEM) in PHACO group and -3.0±0.5 (Mean±SEM) in the ECCE group. There were statistical differences between the two groups. The major complications during and after the operations included posterocapsule scapture, trauma of iris and edema of cornea. Conclusion: PHACO surgery is superior to ECCE in which it has a smaller cutting,and lower astigmatism value and better vision can be obtained.
