Patent ID: 8246679

Claim:
An accommodating intraocular lens for implantation in an eye, the lens having an optical axis, comprising: an anterior viewing element comprised of an anterior optic having refractive power; a posterior viewing element comprised of a posterior optic having refractive power; a biasing system comprising anterior translation arms connected to said anterior viewing element, and posterior translation arms connected to said posterior viewing element, said anterior and posterior translation arms meeting at first and second equatorial apices of said intraocular lens, said biasing system connecting said anterior viewing element and said posterior viewing element for relative movement of said anterior optic relative to said posterior optic along the optical axis between an accommodated state and an unaccommodated state in response to force generated within the eye, said biasing system biasing said anterior viewing element and said posterior viewing element toward the accommodated state in absence of external forces; and a transition member having an end coupled to said anterior viewing element and having an opposite end coupled to the anterior translation arms of said biasing system, said transition member disposed around at least a portion of a circumference of said anterior viewing element and extending anteriorly of said anterior viewing element, said transition member comprising at least one opening there through, said opening configured to provide fluid flow passages between an interior of a capsular bag of an eye into which the lens has been inserted and portions of the eye anterior of the capsular bag, first and second retention members coupled to diametrically opposed portions of the circumference of the anterior viewing element, each of said first and second retention members comprising a distal free end disposed anteriorly and radially outward of said anterior viewing element for contacting the lens capsule of the eye, each of said first and second retention members further comprising at least one opening there through, said openings configured to provide fluid flow passages between an interior of a capsular bag of an eye into which the lens has been inserted and portions of the eye anterior of the capsular bag.
