Simulación del queratocono corneal basado en elementos finitos

Abstract

Keratoconus is a degenerative disease, according to the stage of the disease the treatment of the disease can vary, and there are cases of transplantation. Currently, for different ocular pathological cases, transplants can be from a donor or synthetic type using a type of polymer, being that in some cases this process is not entirely effective. For this disease, the diagnosis has not been clear until today, so the use of computational technology has facilitated its treatment and diagnosis, within this computational technology is the finite element analysis which allows to study a case without being destructive or invasive. Accordingly, in the work presented, the deformation of a synthetic cornea in a degenerative process of keratoconus is analysed using finite elements. The simulation starts from a three-dimensional model considering the standard geometry of the cornea proposed in the literature, then in the dynamic finite element analysis PMMA is considered as material and a displacement of 0.5 mm as loading conditions. Finally, the result shown in the complete deformation of the cornea is associated with what is presented in the literature and justifying the differences and similarities found.
