Finite element based mechanical models of the cornea for pressure and indenter loading

R P Vito et al. Refract Corneal Surg. 1992 Mar-Apr.

Abstract

Background: In this article, we examine the finite element method and its use in mechanical modeling of the cornea.

Methods: Both linear elastic and geometrically nonlinear models are considered. The effects of corneal geometry, boundary conditions, thickness, and the number of layers in the model are determined.

Results: Results indicate that, for intraocular pressure loading, the thickness and the choice of boundary conditions at the limbus are significant.

Conclusions: A model of tonometry showed that simulating the layered nature of the cornea and including the increased flexibility of large deformation are critical.
