摘要
眼外伤、手术均可使角膜屈光状况、角膜内皮发生改变。本文对１６例３２只眼角膜裂伤术后伤眼与健眼进行了角膜地形图检查。发现角膜平均表面规则系数ＳＲＩ为３．４５８３±２．２９，平均表面不规则系数ＳＡＩ为２．２７３６±１．９０，角膜外伤术眼与健眼ＳＲＩ及ＳＡＩ均有显著性差异（Ｐ＜０．０１）。角膜外伤术眼的角膜地形图ＳｉｍＫ差值为５．７１６７±４．２５１８，健眼ＳｉｍＫ差值为１．５４１７±２．９６１１，二者存在显著性差异（Ｐ＜０．０１）。对评价手术的安全性。
Both trauma and operation of eyes can cause the changes of corneal refraction and endothelium In this study corneal topographic analysis was performed on eyes after operation of corneal laceration and the other healthy eyes There were all together 16 patients(32 eyes) The average surface regularity index(SRI) of eyes after corneal operation was 3 4583±2 99,and the average surface asymmetry index(SAI) was 2 2736±1 90 There were significant differences in SRI and SAI between eyes after corneal operation and the healthy eyes (p<0 01) The average simulated keratoscope reading (Sim K) of eyes after corneal operation was 5 7176±4 2518,and that of healthy eyes was 1 5417±2 9611.There was also significant difference(p<0 01) Corneal topographic analysis was an effective method to eveluate the safety,skill and prognosis of corneal operation
