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 investigate the significance of disposable transfusion cap pricking needle in the phacoemulsification of cataract phacoemulsification. Methods Phacoemulsification was performed in patients with age-related cataract phacoemulsification by using disposable puncture knife (group A, 70 eyes) and disposable infusion needle cap puncture needle (group B, 60 eyes) for scleral tunnel incision respectively. Comparison of operation time, postoperative visual acuity, corneal astigmatism and complications. Results The scleral tunnel incision time was 5-9s in group A, and the laparoscopic phacoemulsification was (180 ± 53) s in group A. The incision time was 6-11s in group B, and the operating time was (185 ± 46) s. There was no statistical difference between the two groups Significance (P> 0.05). There was no significant difference in the best corrected visual acuity between the two groups at 1 day, 1 week and 1 month after surgery (P> 0.05). After 1 month, the visual acuity of more than 1.0 in group A and B accounted for 82.85% and 78.33% respectively. The mean preoperative astigmatism in group A was (0.55 ± 0.53) D, and the postoperative astigmatism was (0.73 ± 0.45) D at 1 month after operation. There was no significant difference compared with preoperative values (P> 0.05). The average preoperative astigmatism in group B was (0.65 ± 0.42) D, and the number of astigmatism was (0.80 ± 0.25) D in one month. There was no significant difference between the two groups (P> 0.05). There was no significant difference between the two groups in intraoperative and postoperative complications (P> 0.05). Conclusion The sharp one-time infusion cork needle after simple modification, can be used to do scleral tunnel incision, safe and effective, can effectively reduce the cost of surgery.
