摘　　要：目的 观察冲洗针头液流抛光与传统注吸头机械抛光对白内障超声乳化术后晶状体后囊膜混浊(PCO)的疗效和安全性。方法 纳入2020年6月—2020年12月咸阳市第一人民医院眼科诊断为年龄相关性白内障患者100例(200只眼),随机分为对照组和观察组,最终纳入对照组47例(94只眼),观察组48例(96只眼)。2组患者均行常规白内障超声乳化吸除术后,对照组术中采用注吸头进行后囊膜抛光,再植入人工晶体。观察组植入人工晶体并在囊袋内旋转360°,采用冲洗针头液流抛光后囊膜。记录术前、术后1 d、7 d、1年的最佳矫正视力(BCVA),术后1年PCO评分和后囊膜激光切开率。结果 (1)BCVA:观察组术后各时间点BCVA均较术前改善,差异均有统计学意义(t1 d=36.759、t7 d=40.101、t1年=47.629,均P=0.000);对照组术后各时间点BCVA均较术前改善,差异均有统计学意义(t1 d=52.429、t7 d=56.829、t1年=62.487,均P=0.000)。2组间术后1 d和7 d BCVA比较,差异均无统计学意义(P>0.05),观察组术后1年BCVA优于对照组,差异有统计学意义(t=2.709,P=0.007)。(2)PCO评分:观察组PCO分值为(0.13±0.07)分,低于对照组的(0.25±0.15)分,差异有统计学意义(t=7.090,P=0.000)。(3)后囊激光切开率:2组后囊激光切开率比较,差异无统计学意义(P>0.05)。2组术中和术后均未发生并发症。结论 冲洗针头液流抛光技术可预防白内障术后PCO的发生,操作简单、经济实用、安全可靠,可降低白内障术后PCO发生率,具有一定推广价值。OBJECTIVE To observe the efficacy and safety of irrigation needle fluid polishing compared to traditional mechanical polishing with a needle during phacoemulsification surgery in the prevention of posterior capsule opacification(PCO).METHODS This study included 100 patients(200 eyes)diagnosed with age-related cataracts at the Ophthalmology Department of The First People's Hospital of Xianyang,from June 2020 to December 2020.Patients were randomly divided into a control group and an observation group,with 47 patients(94 eyes)in the control group and 48 patients(96 eyes)in the observation group.Both groups underwent conventional phacoemulsification surgery.In the control group,mechanical polishing of the posterior capsule was performed using a needle,followed by intraocular lens(IOL)implantation.In the observation group,the IOL was implanted and rotated 360°within the capsular bag,followed by posterior capsule polishing using an irrigation needle fluid.Best-corrected visual acuity(BCVA)was recorded preoperatively,and on postoperative first and seventh day,and at one year.PCO scores and the rate of posterior capsule laser capsulotomy were recorded one year postoperatively.RESULTS(1)BCVA:BCVA improved at all postoperative time points compared to preoperative values in the observation group,with statistically significant differences(t1 d=36.759,t7 d=40.101,t1 year=47.629,all P=0.000).The control group also showed significant improvement in BCVA at all postoperative time points compared to preoperative values(t1 d=52.429,t7 d=56.829,t1 year=62.487,all P=0.000).There was no statistically significant difference in BCVA between the two groups on postoperative first and seventh day(P>0.05).However,the observation group had significantly better BCVA on postoperative 1 year compared to the control group(t=2.709,P=0.007).(2)PCO scores:The PCO scores in the observation group(0.13±0.07)were lower than those in the control group(0.25±0.15).There were statistically significant differences in both groups(t=7.090,P=0.000).(3)Pos
