An analttically solvable model that considers the elasticity of the cornea is developed for use in the current and novel corneal refractive surgery procedures. The model assumes that the cornea is a thin spheroid shell with an elastic response to intraocular pressure. The value of the Young's modulus of the post-operative cornea and its dependence on the geometric parameters of the ablation zone are estimated employing "best-fit" approach to nomograms currently used in corneal refractive surgery. These elasticity parameters are applied for quantitative modeling of different types of refractive surgery for myopia.
为用于当前和新型角膜屈光手术程序，开发了一个考虑角膜弹性的可解析模型。该模型假设角膜是一个对眼内压有弹性响应的薄椭球体壳。采用目前角膜屈光手术中使用的列线图的“最佳拟合”方法，估计术后角膜的杨氏模量值及其对消融区几何参数的依赖性。这些弹性参数用于近视不同类型屈光手术的定量建模。
