Capsular membrane implants to increase accommodative amplitude

摘要

A support is coupled to the lens capsule to increase accommodation. The support may be adjustable, such that patient refraction and accommodation can be adjusted following surgery. The support may comprise rigidity sufficient to decrease radial movement of the intermediate portion of the lens capsule. The support can be placed on the intermediate portion to decrease radial movement of the intermediate portion of the lens capsule and increase radial stretching of an outer portion of the lens capsule extending between the zonules and the intermediate portion coupled to the support, such that the amount of accommodation of the eye is increased. The support may comprise a biocompatible material capable of stable coupling to the lens capsule following implantation, such that the far vision refraction and accommodation of the eye can be stable following surgery.

1. An apparatus to treat a human eye having a lens, the lens having a capsule that is complete, the apparatus comprising:
a support that is expandable comprises a first narrow profile configuration and a second wide profile configuration, the narrow profile configuration sized to pass through an incision, the wide profile configuration sized to extend substantially along an intermediate portion of the lens capsule to decrease radial movement of the intermediate portion and increase an amount of accommodation of the eye, wherein the support in the second configuration comprises an arcuate profile having an interior surface configured to directly contact an exterior-anterior surface of the lens capsule at only the intermediate portion thereof, thereby leaving a central portion of the lens capsule free to change curvature; and wherein the intermediate portion is disposed between a central optical portion that permits light to be transmitted through the pupil of the eye, and a peripheral portion attached to zonules of the eye.
