Glasses and contact lenses are popular solutions for many individuals with refractive disorders. Although many techniques have been proposed and tested by the laser eye surgery, photorefractive keratectomy (PRK), and laser in situ keratomileusis (LASIK) are the most widely practiced by using excimer laser. A difficult problem for all refractive surgical procedures is to predict the final refraction because the intraocular pressure (IOP) applies inside the eyes. In this paper, mechanical analysis of cornea was carried out by using finite element method (FEM) and the optical performance of these models was calculated by ray tracng.
