输液器瓶盖穿刺针头在超声乳化白内障手术中的应用

Application on transfixion needle of disposable infusion apparatus for phacoemulsification

目的探讨一次性输液器瓶盖穿刺针头在白内障晶状体超声乳化手术中应用的意义。方法分别应用一次性穿刺刀(A组,70眼)和一次性输液器瓶盖穿刺针头(B组,60眼)做巩膜隧道切口,进行老年性白内障晶状体超声乳化手术。比较手术时间、术后视力、角膜散光情况及并发症。结果A组巩膜隧道切口时间5～9s,白内障晶状体超声乳化吸出手术时间为(180±53)s;B组隧道切口时间6～11s,手术时间为(185±46)s,两组差异无统计学意义(P>0.05)。术后1d、1周和1月两组的最佳矫正视力差异无统计学意义(P>0.05),术后1月A、B两组视力1.0以上者分别占82.85%和78.33%。A组术前散光平均为(0.55±0.53)D,术后1个月散光为(0.73±0.45)D,与术前比较差异无统计学意义(P>0.05)。B组术前散光平均为(0.65±0.42)D,1个月散光为(0.80±0.25)D,与术前比较差异无统计学意义(P>0.05)。两组术中及术后并发症差异无统计学意义(P>0.05)。结论锋利的一次性输液瓶塞穿刺针头经过简单的改装,可用以做巩膜隧道切口,安全有效,能够有效减少手术成本。

Objective To study the application of stopper transfixion needle of disposable infusion apparatus in phacoemulsification. Methods 130 eyes treated with phacoemulsification were divided into disposable blade scleral tunnel incision group （A, 70 eyes） and disposable transfixion needle group（ B, 60 eyes）. Time for tunnel incision and phacoemulsification was recorded. Corneal astigmatism and corrected visual acuity were examined preoperatively, one day, one week, one month postoperatively. Results Theperiods of scleral tunnel incision time and phacoemulsification time were 5-9s and 180±53s respectively for group A,and 6-11s,185 ± 46s for group B. There was no statistic significance between the two groups （ P 〉 0.05 ）. The con＇ected visual acuity over 1.0 were 82.39% and 78.20% respectively for group A and B. The preand postoperative corneal astigmatism were 0.55± 0.5D and 0.7 ± 0.45D respectively in group A. There was no statistic significance between them （P 〉 0.05 ）. The pre- and postoperative corneal astigmatism were 0.65 ±0.4D and 0.8 ± 0.25D, respectively in group B. There was no statistic significance between them （P 〉 0.05）. Conclusion The stopper transfixion needle of disposable infusion apparatus is as safe and effective as traditional disposable blade in phacoemulsification. It＇ s an alternative in special conditions.
