目的：探讨利用角膜地形图来研究翼状胬肉切除术前后角膜表面屈光度的变化。方法：选取2012年6-10月在本院眼科就诊的40例（44眼）原发性翼状胬肉患者，按照随机数字表法将其分为A、B两组，A组行胬肉切除联合术中应用丝裂霉素C，B组行胬肉切除联合角膜缘干细胞，手术前后分别行角膜地形图仪检查，记录主要参数，并比较手术前后角膜地形图变化，进行统计学分析。结果：翼状胬肉切除术后，A、B两组各参数均明显低于术前，且A组各参数均明显低于B组，差异均有统计学意义（P<0.05）。结论：翼状胬肉切除术能够解除翼状胬肉对角膜的机械牵拉及压迫作用，降低散光，提高视力，术中使用丝裂霉素C可降低复发率，有利于角膜屈光状况的恢复。

Objective:To investigate the pterygium excision changes in corneal surface refraction using corneal topography before and after operation.Method:40 patients(44 eyes)with primary pterygium were selected in our ophthalmology from June 2012 to October 2012,they were randomly divided into the group A and the group B.The group A was given mitomycin C pterygium excision combined with intraoperative,and the group B was given pterygium excision with limbal stem cell.Corneal topography examinations were performed before and after operation,the main parameters were recorded,and the changes of corneal topography were compared before and after operation,the results were statistically analyzed.Result:After excision of pterygium,the parameters of two groups were significantly lower than preoperative,and the parameters of group A were significantly lower than the group B,the differences were statistically significant(P<0.05 or P<0.01).Conclusion:Pterygium resection can remove pterygium mechanical pull and compression of the cornea,reduce the astigmatism and improve eyesight,intraoperative use of mitomycin C can reduce the recurrence rate,is beneficial to the recovery of corneal refractive status.
