Abstract
The nonlinear mechanical properties of the cornea, sclera, and optic disk determined previously are incorporated in a finite element mathematical model of a human corneo-scleral shell. This mathematical model is then used to calculate a nonlinear intraocular pressure-volume relation and the forces and volumes in applanation tonometry. These results are compared with experimental results obtained by other investigators. Friedenwald's coefficients of ocular rigidity were also calculated using the model and were found to decrease with increased intraocular pressure.
