Chapter 3 erected the relationship between refraction error and cornel ablation depth in theory . the paper proposed various mathematical models which can be used for proceed the simple myopia , simple hypermetropia , compund myopia astigmatism , compund hypermetropia astigmatism , simple myopia astigmatism , simple hypermetropia astigmatism , mixed astigmatism . the influence of the astigmatic axis and the degree of astigmatism on the correction field is discussed . wavefront aberration guided excimer laser cornea ablation is a main method of customised corneal ablation 以數學的方法研究出了屈光性單純近視、屈光性單純遠視、復性近視散光、復性遠視散光、單純近視散光、單純遠視散光、混合性散光屈光矯正的物理模型;并揭示了不同軸位的轉換規律,對不同散光情況下的初始角膜兩個不同方向的曲率半徑和手術后最終的曲率半徑作了定量的研究。

Based on the diopter status of myopia and hypermetropia , the paper presented the principle of excimer laser refractive surgery , the change of impacting cornea curvature on the cornea diopter . in this chapter , we also discussed excimer laser - corneal tissue interactions and photoablation . determine the relationship between the fluence of arf excimer laser and the cornea ablation rate , attain the relationship between the energy density and the ablation depth 研究了激光與生物組織相互作用、光蝕作用及準分子激光消融角膜的機理;首次定量研究193nm準分子激光高斯光束的切削量與能量密度的關系,計算單個激光脈沖角膜切削量;發現了角膜曲率對切削效果的影響,首次提出了角膜曲率半徑、切削位置與切削深度的關系;首次定量確定了激光光斑參數及其排列方式對術后角膜表面粗糙度的影響,為更精確實現角膜切削和提高切削后角膜表面光潔度、減少手術后角膜渾濁及角膜表面術后不規則提供了理論依據。
