Fig 6. Finite element discretization of a patient-specific model of a human cornea in the physiological configuration.

Fig 6

(a) anterior surface view; (b) NT side view; and (c) NT section. The boundary conditions for static analysis include constrained displacement of the limbus nodes in the radial direction, while the allowed displacements at the limbus mimic the free rotation of the corneal shell about the central limbus circumference.
