目的 :研究不同手术切口对白内障术后角膜散光的影响。方法 :182例 (2 0 1眼 )老年性白内障患者白内障囊外摘除联合人工晶体植入术。所有患者随机分为 2组 ,分别采用角膜缘切口或巩膜瓣切口。于术后不同时期观察角膜散光情况。结果 :巩膜瓣切口组术后角膜散光明显降低 ,与角膜缘切口组比较 ,差异具有显著性 (P <0 .0 5 )。结论 :改良手术切口可减少白内障术后角膜散光 ,提高复明效果 Objective: To study the effect of different incisions on corneal astigmatism after cataract surgery. Methods: 182 cases (210 eyes) of senile cataract patients underwent extracapsular cataract extraction combined with intraocular lens implantation. All patients were randomly divided into two groups, respectively, limbal incision or scleral incision. Corneal astigmatism was observed at different stages after surgery. Results: Corneal astigmatism was significantly lower in the scleral incision group compared with the limbal incision group (P <0.05). Conclusion: Modified surgical incision can reduce corneal astigmatism after cataract surgery and improve the fuming effect
