摘　　要：目的：探讨高负压下劈核联合间断性能量释放技术治疗硬核性白内障的临床效果。方法：选取郁级以上硬核性老年性白内障患者68例82眼,采用高负压下劈核联合间断性能量释放技术进行白内障摘除并植入人工晶状体,观察术中超声时间、术后角膜透明度及视力恢复情况。结果：术中超声能量25%～60%;超声时间58～105（平均85±20）s。术后第1d角膜玉级水肿者28眼,角膜域级水肿者45眼,芋级水肿者9眼,无郁级水肿者。术后第1d视力0.1～0.25者16眼,0.3～0.5者34眼,术后视力﹥0.5者32眼。术后1wk,矫正视力0.3～0.6者11眼,矫正视力≥0.8者71眼。结论：高负压下劈核联合间断性能量释放技术,是无爆破模式的超声乳化仪对硬核型白内障的有效治疗方法之一,有利于碎核,操作方便,安全有效,适合在基层医院推广。AIM： To study the effect of high vaccumchop combined with intermittent-energy release technique in phacoemulsification for hard nuclear cataract. METHODS： Sixty-eight patients （82 eyes） with age related cataract were included in our study, all the eyes had hard nucleus classified as IV or V. High-vaccum chop combined with intermittent - energy release technique were adopted in phacoemulsification of cataract, and IOL were implanted at the same time. Time of phacoemulsification, corneal transparency after operation and visual outcome were recorded. RESULTS： The mean relative ultrasound power was 25%- 60% intraoperative. The time of ultrasound phacoemulsification was 58-105s, mean 85±20s. On the first day after operation, corneal edema classified at grade I were seen in 28 eyes, 45 eyes with corneal edema classified at grade II , and 9 eyes at grade III, no eye at grade IV. Seventy-three eyes with visual acuity I〉 0.3 the first day after operation, and 32 eyes with a visual acuity /〉 0.5. One week after operation, best corrected visual acuity 〉0.5 were seen in 78 eyes, and 71 eyes with a visual acuity better than 0.8. CONCLUSION： High - vaccum - chop combined with intermittent energy - release technique in ultrasonic emulsification instrument with non-burst mode is an effective and convenient way for phacoemulsification ofcataract with hard nucleus, and is especially suitable for primary hospitals.
