The numerical analysis of thermal process proceeding in the human cornea due to a laser irradiation is presented. Heat transfer in the cornea is assumed to be transient and one dimensional. The internal heat sources resulting from laser irradiation based on the Beer law are taken into account. The paper deals with sensitivity analysis of temperature field with respect to the optical and thermophysical parameters of cornea. At the stage of numerical computations the boundary element method has been used. In the final part of paper the results obtained are shown.
