白内障小切口囊外摘出术与超声乳化吸出术的疗效比较

目的 比较白内障小切口囊外摘出术与超声乳化吸出术两种方法的疗效.方法 将326例(360眼)老年性白内障患者按随机数字表法分为A、B组,每组163例(180眼),分别采用超声乳化吸出术及小切口囊外摘出术,均植入后房型人工晶状体,对其术后视力、术中及术后并发症进行比较.结果 术后7 d裸眼视力:A组和B组≤0.4者分别占18.33%(33/180)和18.89%(34/180);0.5～0.9者占66.11%(119/180)和66.67%(120/180);≥1.0者占15.56%(28/180)和14.44%(26/180).术中后囊破裂玻璃体脱出:A组和B组分别占4.44%(8/180)和3.33%(6/180).术后角膜内皮水肿:A组和B组分别占16.11%(29/180)和17.22%(31/180).两种手术疗效相似,差异均无统计学意义(P＞0.05).结论 白内障小切口囊外摘出术经济、简便、容易掌握,适宜于目前我国基层医院开展.

Abstract：

Objective To compare the effect of extracapsular cataract extraction and phacoemulsification. Methods Three hundred and twenty-six cases (360 eyes) of senile cataract were divided into two groups by random digits table with 163 cases (180 eyes) in each. One group underwent phacoemulsification (phacoemulsification group),and the other group underwent extracapsular cataract extraction with small incision(no-phacoemulsifieation group). A comparison was carried out between the two groups of the vision and complications after operation. Results In phacoemulsification group,7 d after operation 18.33%(33/180)had 0.4 or less in vision,66.11%( 119/180) were 0.5-0.9,15.56%(28/180) were 1.0 or better. In no-phacoemulsification group,7 d after operation, 18.89% (34/180) were 0.4 or less in vision,66.67% (120/180) were 0.5-0.9,14.44% (26/180) were 1.0 or better. During operation,posterior capsular ruptured and vitreous prolapsed in 4.44% (8/180) in phacoemulsification group and 3.33%(6/180) in no-phacoemulsification group. Corneal edema:there were 16.11%(29/180) in phacoemulsification group and 17.22%(31/180) in no-phacoemulsification group. The curative effect between the two kinds of operation mentioned above was almost the same and had no significant difference (P ＞0.05). Conclusion The no-phacoemulsification is simple and economical, wihch is suitable for basic hospitals.
