目的探讨不同能量释放模式白内障超声乳化术的效果。方法将286例白内障患者由电脑抽签法分为A、B、C三组。基于相同切口撕囊灌注的常规操作上,分别采用爆破式、脉冲式和连续性超声乳化晶状体核。结果术后A组视功能恢复优于B、C组;A、B、C三组平均乳化时间分别是(37.86±7.12)s、(179.35±43.13)s和(225.68±42.39)s,切口灼伤发生率分别是18.27%、20.30%和68.69%,术后角膜水肿发生率分别是20.19%、25.93%和72.73%,差异有显著统计意义,P<0.01-0.05。结论爆破模式超声乳化白内障吸除术、乳化时间短,视力恢复快,并发症少,可作为白内障乳化术的首选方案。
Objective To explore the effect of phacoemulsification with different energy release modes. Methods 286 cases of cataract patients were divided into A, B and C groups by computerized drawing method. Based on the routine operation of the same incision capsulorhexis, the nucleus of the lens was phacoemulsified by pulsed, pulsed and continuous methods respectively. Results The postoperative visual acuity recovery of group A was better than that of group B and C. The average emulsification time of group A, B and C were (37.86 ± 7.12) s, (179.35 ± 43.13) s and (225.68 ± 42.39) s, respectively The incidences of postoperative corneal edema were 20.19%, 25.93% and 72.73%, respectively, with a significant difference (P <0.01-0.05). The incidence rates of postoperative corneal edema were 18.27%, 20.30% and 68.69% respectively. Conclusion Explosion mode phacoemulsification cataract surgery, emulsification time is short, quick recovery of visual acuity, less complications, can be used as the first choice for cataract emulsification.
