不同方向巩膜隧道切口对白内障术后角膜散光的影响

The after Operation Corneal Astigmatism Influence of Cataract by Different Directions Sclera Tunnel Incision

目的探讨不同方向巩膜隧道切口对白内障术后角膜散光影响情况。方法分析我院眼科2012年2月至2014年4月收治的白内障患者50例临床资料,依据不同方向巩膜隧道切口进行临床分组,治疗Ⅰ组25例和治疗Ⅱ组25例。结果两组白内障术后视力无明显差异,P>0.05,治疗Ⅱ组白内障术后角膜散光明显优于治疗Ⅰ组,P<0.05,差异均有统计学意义。结论采用巩膜反眉状隧道切口,根据术前散光轴位选择小切角可以降低术后角膜散光的影响,促进视力恢复。

Objective To approach after operation corneal astigmatism influence of cataract by different directions sclera tunnel incision. Method Analyzed 50 cases clinical data of cataract patients in our hospital from February 2012 to April 2014, which was to be divided into two groups by different directions sclera tunnel incision, treatment I group 25 cases and treatment II group 25 cases. Result The after operation vision of two group cataract patients were no difference, P〉0.05, the after operation corneal astigmatism of treatment II group was better than treatment I group, P〈0.05, the difference were statistical significance. Conclusion The after operation corneal astigmatism influence is decreased, in According to the preoperative optical axis chooses small chamfer, which was used sclera eyebrow shape tunnel incision, vision is recovery.
