摘　　要：目的探讨白内障不同切口术后角膜地形图变化。方法观察2009年10月至2009年12月在我院眼科行小切口白内障囊外摘除合并人工晶体植入术的患者资料,按切口形状分为两大组:直线形组(长6.0 mm)43例(43只眼),按切口距角膜缘距离不同分3个亚组:A1组(切口距角膜缘1.5 mm)、B1组(切口距角膜缘2.0mm)、C1组(切口距角膜缘2.5 mm);反眉弓形组(弦长6.0 mm)41例(41只眼),按切口距角膜缘距离不同分3个亚组:A2组(切口距角膜缘1.5 mm)、B2组(切口距角膜缘2.0 mm)、C2组(切口距角膜缘2.5 mm)。于术后1周、1个月、3个月随访观察。术后观察角膜地形图变化及统计学分析两种手术切口的术后散光差异。结果切口越远离角膜视部,术后角膜散光度越小,反眉弓形切口较直线形切口在术后早期的角膜表面规则性较好。结论两组切口的结果比较表明,反眉弓形切口较直线形切口对角膜形态影响小。Objective To study corneal topographic map changes in patients after cataract extraction with different incision.Method To observe all patients treated with small incision cataract extraction through broken nuclear technique and intraocular lens implantation from October 2009 to dec 2009 in our hospital.According to the incision shape patients were divided into two groups：straight-line group（length is 6.0mm） 43 patients,and 43 patients（43 eyes） with cataract were divided into three groups according to incisions with different distance from limbus： Group A1（the distance is 1.5mm from incision to limbus）,Group B1（the distance is 2.0mm from incision to limbus）,Group C1（the distance is 2.5mm from incision to limbus）;anti-superciliary arch-shaped group（chord length is 6.0mm） 41 patients,and 41 patients（41 eyes） with cataract were divided into three groups according to incisions with different distance from limbus： Group A2（the distance is 1.5mm from incision to limbus）,Group B2（the distance is 2.0mm from incision to limbus）,Group C2（the distance is 2.5mm from incision to limbus）.All patients were examined by corneal topography and specular microscopy preoperatively,one week,one month and three months postoperatively.Results The corneal incision away from depending on department,the smaller the cornea after scattered spectrophotometry,the eyebrow bow is linear incision in the form of early postoperative incision corneal surface rules better properties.Conclusion The results of two groups of incision comparison shows that the eyebrow bow is linear form of incision corneal incision small effects form.
