Example of a finite element mesh for a human cornea. The solid model is derived from patient-specific geometries acquired by means of an advanced corneal topographer. Once the discretization level (mesh size) has been decided, as dictated by the particular application, the coordinates of the nodes lying on the anterior and posterior surface are determined by interpolation over the grid of topographer points. a Anterior view. b Posterior view. c Side view. d Meridional nasal-temporal section
