Analytic Modeling and Simulating of the Cornea with Finite Element Method

Finite element analysis is a useful tool for modeling surgical effects on the cornea and developing a better understanding of the biomechanics of the cornea. In this paper we proposed a method of building a physical model of the cornea with finite element method. Firstly, an individual 3D modal model of cornea was constructed. Then the finite element model was built up based on a nonlinearly elastic, isotropic formulation. Finally, the intra-ocular pressure and external pressure were simulated with results of cornea shape changes computed via finite element analysis.
