摘　　要：目的:评估超声乳化白内障吸除术的爆破模式与脉冲模式的临床疗效。方法:晶状体核硬度Ⅲ～Ⅴ级的白内障480眼,分为爆破模式组(爆破组)230眼和脉冲模式组(对照组)250眼,分别采用爆破模式和脉冲模式的超声乳化白内障吸除术治疗,观察并比较两组手术过程使用的超声能量、时间、后囊膜破裂情况以及术后第1日的最佳矫正视力及角膜水肿的情况。结果:爆破组所用的超声能量和时间分别为(2.0±0.1)%、0.26(0.24～0.28)min,明显少于对照组的(21±6)%、5.0(1.4～8.6)min(均为P<0.01);爆破组囊膜破裂发生率为1.2%,略低于对照组的2%;爆破组术后第1日的平均最佳矫正视力为0.61(0.43～0.79),明显高于对照组的0.42(0.19～0.65),P<0.05;爆破组术后第1日角膜水肿评分为0.6(0～1.4)分,对照组为1.4(0.4～2.5)分,爆破组角膜水肿情况明显比对照组轻(P<0.01)。结论:爆破模式的超声乳化白内障吸除术比脉冲模式的疗效更好,并发症少,值得临床推广。Objective： To evaluate the effects of burst mode and pulse mode in phacoemulsification. Methods： 480 eyes with age-related cataract in Ⅲ - Ⅴ nuclei subgroup treated by phacoemulsification were divided into burst mode group （230 eyes） and pulse mode group （250 eyes）. The power, time, posterior capsular condition in phacoemulsification and the best corrected visual acuity, corneal edema on the first day after operation were compared between two groups. Results： The power and time in burst mode group were （ 2 ± 0. 1 ） % and 0. 26 （0. 24 ～ 0. 28 ） minutes, significantly lower than that of pulse mode group [ （ 21 ± 6 ） % and 5.0 （ 1.4 ～ 8.6） minutes, P 〈 0.01 ]. Posterior capsular conditions were similar in both groups （ P 〉 0. 05 ）. Best corrected visual acuity on the first day after treatment of burst mode group was statistically better than that of pulse mode group （ P 〈 0.05 ）. Corneal edema on the first day after treatment of burst mode group was significantly lighter than that of pulse mode group （P 〈0. 01 ）. Conclusion： Burst mode is superior to pulse mode in clinical efficacy by phacoemulsification and has less complications.
