Any generally accepted standard of modelling an eyeball’s mounting system still does not exist. The comparison of the results of two extremely different mounting models, i.e., fixed and simply supported, permits us to estimate the part of the kinematic boundary conditions in the solutions of the model. In numerical calculations of the relationship between the changes in the eyeball’s volume and a rise in the IOP (intraocular pressure), the result depends greatly on the type of model’s mounting. Similarly, the optical system of the eye is dependent on the same boundary condition.
