Change in the stress-strain state of the cornea after refractive surgery

Abstract

Changes in the stress-strain state of the cornea with multy-layer structure of the human eye after surgery for vision correction are modeled with finite element package ANSYS. The effect of deformations on the internal radius of curvature after surgery LASIK is studied. The cornea is modeled as a four-layer transversely isotropic shell of variable thickness with layers of different biomechanical properties.
