Abstract
In this study, corneal rupture is assumed to occur when the stress along the fiber direction of a corneal lamella reaches a critical value. By modeling a strip of corneal tissue as a laminate composite, the stress measured from a simple tensile test is related to the stress in the fiber direction within a lamella. This provides an estimate of the tensile strength of a corneal lamella based on the results of tensile tests of strips of human cornea. A laminate composite finite element model of the human cornea is then constructed, and it is shown that the pressure at which the maximum lamella stress reaches the lamella rupture stress agrees with experimental measurements of the rupture pressure of intact human corneas.
