Simulation of Corneal Tissue Mechanical Deformation Based on the Finite Element Method

On the basis of the principle and process of LTK,the paper puts forward a partition,load and restricting solution of gridding and conducts the deformation analysis of cornea under different operation parameters.It has analyzed the deformation quantity of cornea and diversification rate of curvature radius under different parameters.Through analysis and contrast,we can get the effect degree of cornea curvature diversification of different parameter in the operation so as to make certain the operation effect of every parameters in diopter correction.
