Figure 5.

Predicted diseased corneal shapes using the continuum model with the parabolic (ξ = 2 in (4.2)); (a–d), quartic (ξ = 4; e–h) and sextic (ξ = 6; i–l) damage profiles and varying value of central damage ${\mathcal{D}}_{\max }=0.8$ (first column), 0.9 (second column), 0.95 (third column), 0.99 (fourth column). Panels on the right show the circumferential stress ${\tilde{T}}_{\mathit{\Phi }\mathit{\Phi }}$ at ${\mathcal{D}}_{\max }=0.99$ for the three considered values of ξ—this can be compared with the healthy profile in figure 3h.
