2、房型人工晶状体植入术,观察术中实际等效超声能量(totalequivalentpower,,I’EP),有效超声时间(effectivephaeotime,EPT),累计释放能量(cumulativedissipatedenergy,CDE);比较术后角膜内皮计数,角膜厚度,角膜水肿和前节反应状态。结果II级核处理:高频脉冲组EPT和CDE显著高于扭动组(P<0.05),其余各参数无显著差异。III级核处理:高频脉冲组与扭动组EPT无显著差异,高频脉冲组CDE显著低于扭动组(13.38±2.85)VS(29.66±6.79)
3、,差异有统计学意义(P<0.05)。IV级核处理:高频脉冲组与扭动组EPT无显著差异,高频脉冲组CpE显著低于扭动组(23.26±10.76)SVS(34.23士15.99)S,差异有统计学意义(P<0.05)。高频脉冲能量在处理II级和III级核中,TEP、EPT、CDE无显著差异,扭动能量在处理III级核,TEP、EPT、CDE均显著高于II级核处理。两组患者术后1天及1周的角膜内皮丢失率和角膜水肿率差异无统计学意义,但术后1天,高频脉冲组的角膜厚度增加率显著低于扭动组(11.57±9.37)%VS(19.02±10.3
