表面麻醉小切口非超声乳化白内障手术的临床效果分析

包毅

[摘要]目的观察表面麻醉小切口非超声乳化白内障手术的临床效果。方法行小切口非超声乳化白内障人工晶体
手术治疗白内障的患者98例(109眼)，随机分为表面麻醉组49例(54眼)和球后麻醉组49例(55眼)。球后麻醉组给予2％
利多卡因球后阻滞麻醉。表面麻醉组给予倍诺喜(盐酸奥布卡因0．4％)表面麻醉。结果采用表面麻醉和球后麻醉的麻醉
效果比较差异无统计学意义(P>0．05)，同时手术后1个月视力以及散光度情况比较差异无统计学意义(P>0．05)。但是表

面麻醉组的手术时间要显著短于球后麻醉组，表面麻醉组并发症的发生率显著低于球后麻醉组(P<0．05)。结论表面麻醉
下行小切口非超声乳化白内障摘除联合人工晶体植入术麻醉效果良好，能最大限度减少麻醉所带来的并发症，大大减少了病
人的痛苦。
