Figure 3.

Sensitivity analysis of the material properties of the cornea and lid wiper. Change in Young's modulus of cornea does not have any effect on the VMS of the cornea whereas VMS increases slightly with the increase in Young's modulus of the lid wiper (a). Change in Poisson's ratio of cornea does not have any effect on the VMS of the cornea whereas VMS decreases slightly with the increase in Poisson's ratio of the lid wiper (b). Change in density does not have any effect on VMS of the cornea and lid wiper (c). Change in Young's modulus, Poisson's ratio, and density does not have any effect on displacement of the cornea (d–f).
