Observing the Efficacy of Irrigation Needle Fluid Polishing Technique on Posterior Capsule Opacification after Phacoemulsification Surgery
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)Posterior capsule laser capsulotomy rate:There was no statistically significant difference in the posterior capsule laser capsulotomy rate between the two groups(P>0.05).No complications occurred during or after surgery in either group.CONCLUSIONS The irrigation needle fluid polishing technique is simple,cost-effective,and safe for preventing PCO after cataract surgery.It effectively reduces the incidence of PCO postoperatively and is worth promoting.
