Abstract
A haptic supporting an intraocular lens (IOL) in the eye permits radial tension from ciliary muscle relaxation rather than contraction to alter the lens power. The IOL is supported by the overlying tissue in the eye such as iris root, sclera and ciliary process, so that anterior and posterior forces on IOL are balanced, and buckling or displacement of lens in the eye or haptic is reduced or prevented. The haptic is of a thickness so as to increase stiffness and to reduce or prevent IOL buckling or displacement.
