Abstract :
In this paper an axisymmetrical, linear, finite element model of human crystalline lens and zonules is constructed to simulate the accommodation process of the lens, based on the published experimental data. Some detailed modeling procedure and data processing differ from previous studies. Our results show that the optical power increases when ciliary body moves away from the lens. The outcome of this paper proves that numerical modeling is a useful and effective method in the study of accommodation
