目的：探讨LASIK术后眼压变化与角膜厚度改变的相关性。 方法：选择我院104例201眼行LASIK术的患者，进行手术前后的角膜厚度及眼压的测量，对术后角膜厚度及眼压的变化进行直线相关及一元回归分析，求出回归方程，并行F、t检验，检测回归方程的统计学意义。 结果：201眼术后角膜厚度及眼压的变化经行直线相关及一元回归分析，得相关系数R=0.469，R2=0.220，求回归方程为：Y=3.503+0.043X，经F检验及t检验，得F=8448，t=2.906，P=0.007。 结论：角膜厚度及眼压变化呈直线相关，当角膜厚度改变时，所测的眼压值相应改变。

Abstract AIM: To discuss the relation of the change of intraocular tension and corneal thickness after LASIK. METHODS:Intraocular tension and corneal thickness of the 104 cases (201 eyes) preLASIK and postLASIK were examined, the linear correlation of the change of intraocular tension and corneal thickness was turned out,and regression equation was calculated. Statistical significance of regression equation was detected with F，t analysis. RESULTS: The coefficient correlation of the change of intraocular tension and corneal thickness was R=0.469，R 2=0.220，regression equation was Y=3.503+0.043X，F=8448，t=2.906，P=0.007. CONCLUSION:The change of intraocular tension and corneal thickness has linear correlation.When corneal thickness changes ,the value of intraocular tension changes correspondingly.
