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、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。
AIM：To observe the effect of burst mode on phacoemulsi-fication of hard nucleus cataract.
METHODS： Four hundred and eighteen eyes （400 cases） were randomly divided into two groups （pulse group and burst group）. Actual phaco power, phaco time, visual acuity, corneal endothelial cell loss and other complications were recorded.
RESULTS： The actual phaco power in the two groups was 22.42 ＋ 5.65% and 6.30 ＋ 1.28%, respectively. The phaco time in the two groups was （202＋ 25）s and （45＋ 6）s, respectively. In comparison of the power and time between the two groups, the difference was significant （P〈0.001）.Visual acuity was significant improved in both of the two groups postoperatively. The difference between the two groups was statistically significant （P〈0.005）. Postoperative endothelial cell loss was significant lower in burst group than that in the pulse group （P〈0.005）. Serious corneal edema occurred more frequently in the pulse group than that in the burst group. CONCLUSION： During phacoemulsification, burst phaco mode reduced phaco time, actual phaco power, loss of corneal endothelial cell and corneal edema. It is safe to use burst phacoemulsification in clinical.
