摘要
目的 探讨爆破模式行硬核白内障超声乳化吸除术的效果。方法 将400例（418只眼）硬核（Ⅳ～Ⅴ级核）白内障患者随机分为脉冲组和爆破组行超声乳化吸除术。记录两组患者术中实际使用的超声能量和时间、术后视力及角膜内皮细胞密度，并观察手术并发症的发生情况。结果 脉冲组和爆破组术中实际使用的超声能量分别为（22．42±5．65）％及（6．30±1．28）％；超声时间分别为（202±25）s及（45±6）s；比较两组所用超声能量和时间，差异均有显著意义（P〈0．001）。两组患者术后视力均有提高，相比较差异有显著意义（P〈0．05）。术后爆破组角膜内皮细胞丢失率明显低于脉冲组（P〈0．001）。结论 应用爆破模式行硬核（Ⅳ～Ⅴ级核）白内障超声乳化吸除术，可明显减少超声能量和时间，降低角膜内皮细胞丢失率，减少术后早期角膜水肿，值得推广使用。
Objective To abserve the effect of burst mode on phacoemulsification of hard nucleus cataract. Method Four handreds and eighteen eyes （400patients） were rardomly divided into groups（ pulse group and burst group）. Actual phaco power, Phaco rime,visual acuity,corneal endothelial cell loss and other complications were recorded. Result The actual phaco power in the two groups was 22.42%±5.65% and 6.30%±1. 28% ,respectively. Phaco time in two groups was （202±25） s and （45±6） s, respectively. In comparison of the power and time between the two groups, the difference between the pulse group and burst group was significant（ P 〈0. 001 ）. Visual acuity was significant improved in all two groups postoperatively. The difference between the pulse and burst group was statistically significant（ P 〈0.005 ）. Endothelial cell loss postcperatively was lower in burst group than that in the pulse group was signiiican（ P 〈0. 005）. Serious corneal edema occurred more frequently in the pulse group than that in the burst group. Condusions Burst Phaco mode reduced phaco time and actual phaco power consumed during phacoemulsification and reduced the loss of corneal endothelial cell and corneal edema. It is safe to use the burst phacoemulsification clinically.
