摘　　要：目的探讨Orbscan-Ⅱ在准分子激光原位角膜磨镶术(LASIK)术前后检查中的应用价值。方法对41例(80只眼)屈光不正患者于LASIK术前和术后1、6个月用Orbscan-Ⅱ检测角膜后表面隆起度及相关因素并进行统计学比较。结果手术前与术后1、6个月Orbscan-Ⅱ测量的角膜后表面隆起度有统计学差异(P<0.05);高度近视组角膜后表面隆起度改变量均大于中低度组的改变量,结果有非常显著差异(P<0.05)。术后1、6个月Orbscan-Ⅱ角膜后表面隆起度改变量与角膜平面屈光等效球镜度改变量之间有相关关系(r=0.404,P<0.05;r=0.54,P<0.05);术后6个月角膜后表面隆起度改变量与激光切削量有相关性r=0.33P<0.05。结论Orbscan-Ⅱ角膜后表面隆起度检测对LASIK术后动态观察及处理具有重要指导意义。Objective To study the usefulness of the Orbscan-Ⅱ in the corneal posterior surface elevation examination for LASIK.Methods The 80 eyes of 41 cases was assessed using Orbscan-Ⅱ before LASIK and 1 month and 6 months after the operation. The corneal posterior surface elevation and the corneal power after LASIK were analyzed.Results The corneal posterior surface elevation before and after LASIK were statistically significant(P<0.05).The changes of posterior surface elevation in high myopia were significantly more than that of mild-moderate myopia after LASIK(P<0.05).The changes of posterior surface elevation correlated significantly with the △SEQ(r=0.404, P<0.05;r=0.54,P<0.05)1 month and 6months after LASIK.Conclusion The corneal posterior surface elevation examination using Orbscan-Ⅱ before and after the operation is very important for LASIK.
