Mathematical modeling of the forces between an intraocular lens and the capsule.

Purpose: To model the pressure relationship between an intraocular lens (IOL) and the capsular bag.

Setting: Department of Physics, Kings' College, London University, London, United Kingdom.

Methods: A mathematical model was made of the forces between the capsule and IOL showing that the pressure related to the local radius of curvature of the IOL at any given point.
