Geometric parameters of the Bennett-Rabbetts schematic eye.

This schematic eye is based on the Bennett-Rabbetts model as described in [1]. Sizes are specified in mm.

Notes

The Bennett-Rabbetts eye is a three-surface schematic eye with a single cornea surface. In visisipy, this means that only the posterior corneal surface is modelled, and the corneal thickness will be equal to zero. The Bennett-Rabbetts geometry does not specify the retinal curvature, so the value from the Navarro model is used by default.
