A method for simulating the behavior of an eye comprising the steps of (i) generating a FEM model of the eye representing the physical structure of the eye, the FEM model including an elastic walled corneo-scleral shell, (ii) modeling deformations of the eye with the FEM model, the deformation modeling including the simulated application of at least one external force to the FEM model, and (iv) obtaining FEM model solutions iteratively in an incremental fashion, whereby adjustable nodal pressure is introduced inside the corneo-scleral shell.
