Capsular membrane treatments to increase accommodative amplitude

摘要

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.

主权项

1. A method of treating an eye having a lens and a lens capsule, the lens capsule having a central portion, a peripheral portion and an intermediate portion, the peripheral portion connected to zonules of the eye, the intermediate portion corresponding to a location between the peripheral portion and the central portion, the method comprising:
treating the intermediate portion of the capsule to stiffen the intermediate portion to increase curvature or movement anteriorly of at least a portion of the lens when the eye accommodates.
