Patent ID: 6846326

Claim:
An accommodating intraocular lens for implantation in an eye having an optical axis, said lens comprising: an anterior portion comprising: an anterior viewing element having a periphery and comprised of an optic having refractive power; an anterior biasing element attached to said anterior viewing element at a location, said anterior biasing element having at said location a thickness in a direction substantially perpendicular to said periphery and a width in a direction substantially parallel to said periphery, the ratio of said width to said thickness being equal to or greater than 3; and a posterior portion comprising: a posterior viewing element having a periphery, said posterior viewing element in spaced relationship to said anterior viewing element, said posterior viewing element comprised of an optic having refractive power; a posterior biasing element attached to the posterior viewing element; said anterior biasing element and said posterior biasing element meeting at first and second apices of said intraocular lens, such that force on at least one of said anterior portion and said posterior portion causes relative movement of said viewing elements between an accommodated state and an unaccommodated state, said viewing elements being separated when in the accommodated state; wherein said anterior biasing element comprises four arms, two of which extend from the anterior viewing element toward the first apex, and another two of which extend from the anterior viewing element toward the second apex; wherein said anterior biasing element exerts a biasing force on said anterior viewing element, said biasing force being greater when said viewing elements are in said unaccommodated state, than when said viewing elements are in said accommodated state.
