Patent ID: 7674288

Claim:
An artificial lens kit for implantation in a lens capsule of natural eye in which the lens capsule has an equator, comprising: an intraocular lens having an optic portion and a haptic means provided on a peripheral end of said optic portion; said haptic means being adapted to contact an inner surface region of said lens capsule corresponding to said equator; an intraocular ring assembly in which said intraocular lens is supported in a coaxial relation therewith, said intraocular ring assembly including: a first ring element having a center and a support means for supporting said haptic means of said intraocular lens therein; a second ring element having a center; a biasing means provided between said first ring element and said second ring element, wherein said first and second ring elements are resiliently urged by said biasing means in a direction opposite to each other, such that the center of said first ring element is in a coaxial relation with the center of said second ring element; and wherein a first securing means is provided between said first ring element and said biasing means, whereas a second securing means is provided between said second ring element and said biasing means, and wherein said biasing means is secured between said first and second ring elements via said first and second securing means, wherein said biasing means comprises at least two elastic elements each having a configuration of generally figure-of-eight, and wherein each of said at least two elastic elements is secured, at one end portion thereof, to said first ring element by said first securing means, while being secured, at another end portion thereof, in said second ring element by said second securing means, wherein said first securing means comprises: at least two first grooves formed in said first ring element; and at least one first securing cavity formed in each of said at least two first grooves, said first securing means further including at least one first anchor portion formed in each of said at least two elastic elements; wherein said second securing means comprises; at least two second grooves formed in said second ring element; and at least one second securing cavity formed in each of said at least two second grooves, said second securing means further including at least one second anchor portion formed in each of said at least two elastic elements, and wherein said at least one first anchor portion and said at least one second anchor portion are securely engaged in said at least one first securing cavity and said at least one second securing cavity, respectively, while said at least two elastic elements are partway fitted in said at least two first grooves, respectively, and are also partway fitted in said at least two second grooves, respectively.
