【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6.0mm)43例,按切口距角膜缘距离不同分三个亚组：A1组(切口距角膜缘1.5mm)、B1组(切口距角膜缘2.0mm)、C1组(切口距角膜缘2.5mm)；反眉弓形组(弦长6.0mm)41例,按切口距角膜缘距离不同分三个亚组：A2组(切口距角膜缘1.5mm)、B2组(切口距角膜缘2.0mm)、C2组(切口距角膜缘2.5mm)。于术后1w、1m、3m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。结论距角膜缘距离2.0mm的反眉弓形切口更适合于临床
[Abstract]:Objective To study the changes of corneal topography after cataract surgery .

method

The patient data of cataract extraction combined with IOL implantation from October 2009 to December 2009 were observed and divided into two major groups according to the shape of incision : linear group ( length 6.0 mm ) 43 cases , according to

The distance between the incision and the corneal margin was divided into three sub - groups : A1 group ( 1.5 mm from the cornea margin ) , B1 group ( 2.0 mm from the cornea margin ) and C1 group ( 2.5 mm from the edge of the cornea ) ;
41 cases of eyebrow arch group ( chord length : 6.0 mm ) , by cutting

The corneal topography was measured at 1w , 1m and 3m postoperatively . The changes of corneal topography and the postoperative astigmatism were analyzed statistically .

Results

The smaller the incision is away from the cornea , the smaller the postoperative corneal astigmatism , the better regularity of the corneal surface at the early postoperative period .

Conclusion

An arch - shaped incision with a distance of 2.0 mm from the edge of the cornea is more suitable for clinical use
