| 摘 要： | 目的 评价白内障囊外摘除术不同切口对术后视力和角膜屈光力的影响.方法 分别应用10mm角巩膜阶梯状弧形切口和改良6mm巩膜隧道式眉状切口对108只患眼行白内障囊外摘除术,于术后3个不同时期比较两组术后视力和角膜曲率.结果 改良的巩膜隧道式切口组术后0.5,3和6个月的角膜屈光力差明显低于传统的角巩膜阶梯状切口组(P＜0.05),且视力显著高于后者(P＜0.05).结论 改良的巩膜隧道式眉状切口为一有效控制术后角膜散光的术式.

| Abstract: | Objective To evaluate the impact of different incisions on post-operative visual acuity and corneal refractivity after extracapsular cataract extaction.Methods The visual acuity and corneal refractivity in 108 eyes underwent extracapsular cataract extraction with traditional 10mm arc-shaped scleral ladder incisions and modified 6mm frown-shaped scleral tunnel incisions were examined and were compared at three post-operative periods.Results The mean increase in corneal refractivity in modified group was significantly less(P<0.05) and the corrected visual acuity was much better(P<0.05)than that in traditional group at 0.5 month,3 months and 6 months.Conclusion 6mm frown-shaped scleral tunnel incisions is effective method to control the post-operative corneal astigmatism in cataract surgery. |
