摘要
目的:比较与评价切口的缝合与否对巩膜隧道切口超声乳化白内障吸除联合硬人工晶状体植入术后角膜散光的度数及轴向的变化及手术效果。方法:将100例(116眼)白内障患者行白内障超声乳化吸除联合硬性人工晶体植入术,按切口缝合与否分为A、B两组,A组:行切口缝合1针者53例(62眼),B组:不缝合者47例(54眼),分别于术前及术后1周、1个月及3个月使用角膜地形图仪及自动屈光仪测量角膜散光变化。结果:术后1周、1个月、3个月平均手术性角膜散光度分别为(+1.36±1.61)D和(-1.27±1.72)D,(+0.77±0.67)D和(-2.07±1.82)D,(+0.39±0.55)D和(-1.95±1.93)D,差异有显著性(P<0 0 5);A、B两组术后角膜散光轴均有早期的顺规向逆规转化。结论:对于小切口超声乳化白内障吸除联合人工晶状体植入术巩膜隧道切口缝合一针可稳定提高术后的视力,减少术后的角膜逆规散光,同时也提高了切口的安全性,特别对于基层及复明工程手术值得采用。
Objective：To compare and evaluate the operative effect and change of degree and axial of postoperative astigmatism by phacoemulsification combined with hard intraocular lensimplantation.Methods：116 eyes of 100 patients treated with phacoemulsification combined with hard intraocular lensimplantation were divided into groups A and B by suturing the incision or not.62 eyes of 53 patients in group A were treated with 1 needle through scleral tunnel incision.The other 54eyes of 47 patients in group B were not sutured.All the patients’ corneal astigmatism were examined by corneal topography and auto-refkeratometer preoperatively,one week,one month and three months postoperatively.Results： The postoperative corneal astigmatism at one day,one month and three months were（＋（＋1.36±1.61）Dand（-1.27±1.72）D,（＋0.77±0.67）Dand（（-2.07±1.82）D,（＋0.39±0.55）Dand（（-1.95±1.93） respectively.There was significant difference between the astigmatism（P〈0.05）;The previous astigmatism with the rule conversed to against-the-rule astigmatism in all patients.Conclusions： The suture of scleral tunnel incision with 1 needle can improve postoperative vision stably,Reduce the postoperative astigmatism and improve the safety of incision at the same time.Especially useful for basic unit and rebright engineering
