This article presents a methodology for two-dimensional modeling of the human eye to analyze the heat transfer in biological tissues, in this case, ocular tissues. The technique used was the finite differences method in the time domain. With a proposal for a numerical simulation of the problem, see that this type of work aims to promote the development of tools that help detect errors in biomedical engineering. Several medical procedures, including surgical ones that use laser, whose main limiting factor is the increase in temperature in living tissue, a fact that can cause irreversible damage, even evaporating. For example, refractive eye surgery using a laser. The simulation is intended to calculate the temperature gradient to guide the physician more precisely before an intervention. An example of this is certain types of inoperable tumors that can be irradiated with laser sources. Their function is to cause a rise in local temperature to destroy cancer cells without thermal damage to the healthy region.
