DEVICE AND METHOD FOR MODELLING A CORNEA

摘要

In order to model a cornea for simulating tissue sections in the cornea a patient-specific finite element model of the cornea is generated (S2). A first group of tissue sections with main fibres running parallel to the cornea surface are distributed in the finite element model according to a first distribution function (S22). A second group of tissue sections with inclined crosslink fibres running non-parallel to the cornea surface is produced in the finite element model according to a second distribution function (S23). The second distribution function distributes (S23) the crosslink fibres with a non-uniform weighting function over the depth of the cornea, from the outer surface of the cornea to the inner surface thereof.
