Modelling of heat transfer in a laser irradiated eye retina

Ultimately, this research is to develop a versatile 3D non-axial finite element model of the whole human eye that is not limited to any specific ophthalmic treatment. The goal is to include the asymmetric cooling by an equivalent uniform layer representing the vascular system of the choroid. In this paper, we trialled the feasibility of simulating conductive heat transfer through the retina as the base step towards a 3D model. This was done by developing a 2D axial model of the retina in which most heat is absorbed in the retinal pigment epithelium.
