However, according to the biodynamic principle of a closure glomus梕yeball, the posterior corneal surface tends to change its curvature with the decrease of the corneal thickness responding to the action of intraocular pressur.
就LASIK而言，角膜后表面的改变有可能直接或间接地影响手术疗效，并有可能成为一些并发症的直接或潜在的危险，故有必要对LASIK术后角膜后表面的变化进行研究。
