Fig. 11 — Finite element model of the averaged human eye; (a, b, c) without considering localised material model (Ogden model parameters are μc = 0.07, αc = 110.8, μs1 = 0.441, αs1 = 124.5, μs2 = 0.349, αs2 = 138.5, μs3 = 0.308 and αs3 = 162.2); (d, e, f) considering localised material model. Von Mises stresses distribution is shown in (a, d), and displacements distribution (b, e) is plotted at 15 mmHg IOP. The difference between von mises stress in the ring-segmented model (c), and regional element-specific model (f) is shown in (g) as a map and in (h) as a polar plot. Finally, maximum logarithmic strains resulted in the stress-free analysis and their relevant displacements are presented in (i). The Z-axis is aligned with the axial direction of the eye in all subplots.
