【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。更多还原

【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.更多还原
