简介:目的评价表面麻醉下白内障超声乳化手术二种切口(角膜、巩膜切口)不同手术阶段疼痛感觉及镇痛效果.方法铺巾前、开睑后滴"0.4%爱而卡因"表面麻醉剂二次后手术.随机选择角膜切口组,巩膜切口组各120例,在手术各阶段中不作任何提示,征询病人疼痛感觉,详细记录按疼痛分级表,并客观评价镇痛效果.结果本组病例手术时间范围5~25min,平均7.2min.两组病例在水分离,超声乳化,清除皮质阶段中角膜切口组3级疼痛以下发生率分别为9.2%,25.0%,12.5%;巩膜切口组分别为12.5%,22.5%,13.3%.二组间差异无显著性(P>0.05).所有病例均能很好耐受手术,顺利完成手术并植入囊袋内人工晶状体.后囊膜破裂率为3.8%,前囊撕裂率5.8%,无晶状体核坠入玻璃体内和眼内大出血等严重并发症.结论表面麻醉方式行超声乳化手术是安全而有效的.
