The unloaded geometry. Zoom onto the macroscale geometry of an idealized two-dimensional corneal slice (created with BioRender.com). The unloaded-configuration cornea is shown in blue, the key parameters are indicated in red and the green dotted lines (circles) depict the curves of constant Φ ($\tilde{R}$). The unloaded configuration is then discretized (N = 4, M = 80, γ = 20). The panel on the bottom right presents a zoom onto the unit cell with the dimensional lengths of the elements (denoted with tilde) dependent on the radial position (index i). Terms in red represent corresponding quantities in the continuum limit (N → ∞) of the dimensionless model. Note that while the unit cell for a finite N and M forms an isosceles trapezoid, in the continuum limit this becomes a rectangle.
