摘　　要：目的观察拦截劈裂碎核结合冷超声乳化在白内障术中的应用效果。方法选择白内障患者116例(116眼),男64例,女52例,平均年龄66.3岁(57～89岁),晶状体核硬度Ⅱ级～Ⅴ级,对所选患者施行拦截劈裂法冷超声乳化手术,观察术中术后并发症及术后视力恢复情况。结果本组患者平均有效超声乳化时间(EPT):(7.35±6.81)S,平均总超声乳化时间(UST):(48.53±45.32)S,平均超声能量(7.52±5.75)%。所有患者均顺利一期行人工晶体囊袋内或睫状沟植入;术中4眼发生后囊膜破裂伴玻璃体脱失,经处理后顺利行人工晶体睫状沟植入。术后第一天检查发现较明显角膜水肿9眼,经治疗后均于术后一周内消退;术后第一天裸眼视力≥0.8者19眼(16.4%),≥0.5者46眼(39.7%),<0.5者51眼(43.9%);术后一个月裸眼视力≥0.8者42眼(36.2%),≥0.5者58眼(占50.0%),<0.5者16眼(13.8%)。结论拦截劈裂法结合冷超乳可以更有效的粉碎晶体核,从而降低超声乳化时间,减少超声能量使用,具有术后反应轻、视力恢复快等优点,是一种较好的白内障手术方式。Objetive To evaluate the effect of stopping and chopping skill combined with cold phacoemulsification for cataract extration. Methods One hundred and sixteen eyes of 116 patients with cataract, grading level II and V ,were operated with stopping and chopping combined with cold phacoemulsifieation .The complications during and after surgery , visual acuity after surgery were observed. Results Average effective power time of phacoemulsification was 7.35±6.81 seconds, average ultrasound time was 48.53± 45.32 seconds .Average ultrasound power was 7.52 ± 5.75%. Intraocular lens were successfully implanted to capsular bag or ciliary groove in 116 patients. Posterior capsule rupture and vitreous loss occurred in 4 eyes. Nine eyes showed severe corneal edema at postoperative 1 day and subsided within postoperative 7 days .Naked visual acuity 30.8 was in nineteen eyes （16.4%）, 30.5 in forty six eyes （39.7%）, 〈 0.5 in fifty one eyes （43.9%） at postoperative 1 day..Naked visual acuity ≥ 0.8 was in forty two eyes （36.2%）, ≥ 0.5 in fifty eight eyes （50.0%）, 〈 0.5 in sixteen eyes （13.8%） at postoperative 1 month. Conclusion Stoping and choping skill combined with cold phacoemulsification can effectively split lens nucleus and reduce the time and energy in the process of the operation, while less reaction and quickly visual acuity recovery could be got. Therefore it is an advanced way of phacoemulsification.
