Abstract :
Finite element analysis (FEA) plays an important role in the biomechanical field. In this paper, we used FEA method in the area of ophthalmology. We generated an eyeball - extraocular muscles (EOMs) model and converted it to meet the need of FEA process. We exerted outside forces on the structure for nonlinear computation and achieved the distributions of displacement, stress and strain. The results corresponded with the basic theory of ophthalmology. We also put forward some related aspects for discussion and advanced studies
