Abstract
Methods and apparatus treat the lens capsule so as to increase accommodation of the eye. The treatment of the lens capsule may comprise treating a portion of the lens capsule so as to stiffen the treated portion and improve accommodation of the eye. The intermediate portion of the lens capsule may located between an optically used central portion of the lens capsule and a peripheral portion of the lens capsule connected to zonules of the eye. The stiffened intermediate portion of the lens capsule can improve coupling of the peripheral portion of the lens capsule to the central portion of the lens capsule, such that an amount of accommodation of the optically used central portion of the lens is increased. As the force of the lens capsule to a lens disposed within the lens capsule is increased, the lens may comprise the natural lens of the eye or an artificial lens such as an accommodative IOL. The treatment of the eye to stiffen the intermediate portion may comprise application of one or more of an energy or a substance to the intermediate portion.
