摘要： 目的探讨利用角膜地形图做角膜切口以矫正散光的效果。方法对97例患者(102眼,术前散光范围0.25～5.75D),术前行角膜地形图检查,然后随机分为A、B两组。A组(51眼)常规做颞上方巩膜隧道切口,B组在角膜曲率最大轴位做透明角膜切口,行白内障超声乳化,植入折叠式人工晶体。于术后1 d、1周、1个月和3个月时对患者进行视力、裂隙灯、眼底、角膜地形图检查,观察角膜散光的变化。结果A组患者术后1 d、1周、1个月、3个月时角膜散光与术前比较差异无显著性意义(P>0.05)。B组患者术后1 d、1周角膜散光较术前增加,术后1个月、3个月散光较术前改善。术前散光≤1.5 D者术后平均散光(0.52±0.14)D;术前散光1.5～2.5 D者术后平均散光(0.88±0.53)D;术前散光>2.5 D者术后平均散光(1.5±0.72)D。结论通过角膜地形图引导的手术切口可以较好地矫正术前部分散光,获得满意视力。

Abstract: Objective To explore the effect of correcting astigmatism with corneal incision guided by the corneal topography preoperatively.Methods 97 patients(102 eyes) having undergone phacoemulsification and foldable introcular lens implanation,were divided into two groups according to the incision.Superior temple sclera tunnel incision was made on 51 eyes of the group A,and the clear cornea incision was made on the steepest meridian for the group B(51 eyes).The preexisting cornea astigmatism of all patients reneged from 0.25 D to 5.75 D.Corneal topography examination was made before the operation and one day,1 week,1 month and 3 months after surgery except for visual acuity,slit lamp and fundus examination.The value of surgical induced cornea astigmatism was observed.Results In the group A,the differences were not statistically significant between pre-operation and 1 day,1 week,1 and 3 months after surgery for the value of corneal astigmatism(P>0.05).In the group B,the value of corneal astigmatism in 1 day and 1 week after surgery were a little greater than that of pre-operation,but 1 month later,that was significant better than that pre-operation.The value of corneal astigmatism was reduced from 1.5 D before surgery to 0.52±0.14 D after surgery,from 1.5～2.5 D to 0.88±0.53 D and from over 2.5 D to 1.5±0.72 D respectively.Conclusion The incision guided by corneal topography can correct cornea astigmatism existed pre-operation and get the best visual outcome.
