Intraocular lens

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.

2. The lens of claim 1 , wherein said at least one opening is located radially inward of an anteriormost portion of said first or second transition member relative to the optical axis of the lens.

3. The lens of claim 1 , wherein said first and second transition members are evenly spaced around said anterior viewing element.

4. The lens of claim 3 , wherein said first and second transition members are diametrically opposed.

5. The lens of claim 1 , wherein each of the first and second transition members includes an inclined member having a lower portion disposed about and coupled to the anterior viewing element and an upper portion disposed radially outward from the lower portion.

6. The lens of claim 5 , wherein the inclined member has an inclined surface comprising the openings.

7. The lens of claim 5 , wherein each of the anterior translation arms have a first end coupled with the upper portion of the inclined member and a second end coupled with the first or second equatorial apices.

8. The lens of claim 1 , wherein the anterior viewing element or the posterior viewing element has an aspheric surface.
