| 目的探讨钩针预劈核在白内障超声乳化手术中的应用效果。方法研究对象是 2017年1—9月在芜湖市第二人民医院眼科住院治疗的全部年龄相关性白内障病人 46例(53眼)，晶状体核硬度 Ⅲ~Ⅳ级，将病人按随机数字表法分为两组，即钩针预劈核组(23例27眼)和超声拦截劈核组(23例26眼)比较两组术中实际有效超声时间(EPT)、术后角膜水肿、术后裸眼视力及并发症等情况。结果钩针预劈核组的 EPT(6.69±2.69s低于超声拦截劈核组s；)，(9.49±3.03)(P＜0.05)角膜水肿发生率较超声拦截劈核组低，差异有统计学意义(P＜0.05)；两组病人术后裸眼视力均有所提高，但术后视力提高情况钩针预劈核较超声拦截劈核组更为明显；两组均无严重并发症发生。结论钩针预劈核的 EPT短，术后角膜水肿的发生率低，较早地改善病人术后视力，无严重的并发症发生。 |

| Objective Investigate the application effect of crochet prechopping nucleus in phacoemulsification. Methods The study subjects were 46 patients(53 eyes)of all age?related cataract patients with Grade Ⅲ?Ⅳ of nucleus hardness hospitalized inWuhu Second People Hospital from January to September of 2017.The patients were randomly assigned into two groups:the crochet prenuclear group(27 eyes of 23 cases)，the ultrasound intercepting nucleus group(26 eyes of 23 cases).The effective ultrasound time(EPT)，postoperative corneal edema，and the uncorrected visual acuity and complications were compared.Results The EPT of the crochet prechopping group(6.69±2.69)s was lower than(9.49±3.03)s of the control group(P＜0.05).The incidence of corneal edema was lower than that of the ultrasound intercepting nucleus group，and the difference was significant(P＜0.05).The visual acu? ity of the two groups was improved after operation，but the improvement of visual acuity in the crochet prechopping group was moreobvious than that in the ultrasound intercepting nucleus group.There was no serious complication in the two groups. Conclusion The EPT of crochet prechopping is short，and the incidence of corneal edema is low after operation，which improves the vision of pa? tients early and has no serious complications. |
