(a) Four types of cornea-based structures used in the finite element models with type I representing a plate, type II a spherical shell, type III a normal cornea, and type IV a keratoconic cornea; (b) schematic of a finite element model of cornea-like structure under central displacement excitation; and (c) the OCE-measured and mathematically fitted temporal profile of the displacement excitation.
