Figure 8. Fitting of the modified NITI model to the ex vivo porcine corneal dataset.

a) The modified NITI model was used to fit ex vivo corneal dispersion data pressurized at 5, 10, 15, and 20 mmHg. The in-plane modulus μ was set at 1.0 MPa while the tensile prestress ${\sigma }_{\theta }$ was approximated via Eq. (40). b) The resulting dispersion curves are shown as linear wavenumber vs. frequency plots. c) The corresponding phase velocity curves are shown on the right. All parameters are summarized in Table 2.
