1. An accommodating intraocular lens (IOL) for implantation in an eye, the lens having an optical axis, comprising:
an anterior viewing element having a circumference and comprising an anterior optic; a posterior viewing element having a circumference and comprising a posterior optic; a biasing system comprising first and second anterior translation arms connected to said anterior viewing element, and first and second 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; a first arcuate transition member having an end coupled to said anterior viewing element and having an opposite end coupled to the first anterior translation arm of said biasing system, said first transition member disposed around at least a portion of the circumference of said anterior viewing element and extending anteriorly and radially outward of said anterior viewing element, said first transition member comprising at least one opening there through, said at least one 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, a second arcuate transition member having an end coupled to the circumference of said anterior viewing element and having an opposite end coupled to the second anterior translation arm of said biasing system, said second transition member disposed around at least a portion of the circumference of said anterior viewing element and extending anteriorly and radially outward of said anterior viewing element, said second transition member comprising at least one opening there through, said at least one 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; and first and second distending members coupled to diametrically opposed portions of the circumference of the posterior viewing element, each of said first and second distending members extending to locations significantly anterior of an anterior side of the posterior viewing element. |
