Abstract:
The purpose of this research is to establish a mathematical model to determine corneal shape and apply that technique to excimer laser refractive surgery. Seeing that the corneal physiological surface is aspheric, the preoperative corneal shape can be approximated by toric surface with radii of curvature Rix, Riy. The relationship between refraction error and corneal ablation depth was deduced in theory. Various mathematical models which can be used for compound myopia astigmatism, compound hypermetropia astigmatism, simple myopia astigmatism, simple hypermetropia astigmatism, mixed astigmatism have been proposed. Clinic practice shows that the technique proposed can correct regular astigmatism and achieve satisfied results.
