THERMAL EFFECTS OF CORRECTIVE LASIK SURGERY

摘要

In this paper we report a numerical, 3D finite element study on the thermal effects associated to the eye refractive laser surgery (LASIK) aimed at correcting the vision. To keep the problem tractable, the models are reduced to the cornea and aqueous humor regions. The main objective is the understanding of the heat transfer process within the cornea and its relation to the optical correction aimed by the LASIK surgical procedure. Several difficulties related to the lack of geometrical information and thermo-mechanic properties are commented. In this study we used FIDAP and GAMBIT as software tools
