Abstract

Purpose:Many patients come afoul by the over correction or under correction of the eye muscles after strabismus surgery. This is related to the individual properties of anyone’s distinct eye muscles. Therefore, it is necessary to have accurate information about the living soft tissues in simulations and the proper modeling of the human eye muscles. The aim of this study was to present a three element model which may contribute to more accurate surgery. Methods: A three element model consisted of a spring in parallel with a Maxwell element which was composed of a dashpot and a spring in series. The response of the linear and nonlinear three element model was fitted to the obtained creep graphs. Results: The results showed a good fitness in both the linear and non-linear models. Conclusion: Since the living soft tissues generally exhibit nonlinear behavior, these results may indicate that the experiment have performed in linear range. One of the reasons of non-linear behavior of eye muscle may be related to pulley complex mechanism.
