6. The intraocular lens of claim 4 , wherein the outer structure further comprises at least one intermediate weakened region circumferentially disposed between first intermediate member and the second intermediate member.

7. The intraocular lens of claim 6 , wherein the at least one intermediate weakened region is circumferentially disposed equidistant between first intermediate member and the second intermediate member.

8. The intraocular lens of claim 1 , wherein at least one of the weakened regions comprises a hinge.

9. The intraocular lens of claim 1 , wherein at least one of the weakened regions has a radial thickness that is less than a radial thickness of the outer structure in a region proximal the at least one weakened region.

10. The intraocular lens of claim 1 , wherein at least one of the weakened regions has a thickness along the optical axis that is less than a thickness along the optical axis of the outer structure in a region proximal the at least one weakened region.

11. The intraocular lens of claim 1 , wherein the outer structure is made of a first material and at least one of the weakened regions is made of a second material that is more bendable than the first material.

12. The intraocular lens of claim 1 , wherein the outer structure comprises a first arm and the second arm with a void therebetween.

13. The intraocular lens of claim 12 , wherein at least a portion of the first arm is slidably disposed to at least a portion of the second arm.

an optic centered about an optical axis;

an outer periphery defined by an intersection of a maximum outer radial extent of the support structure and a plane perpendicular to the optical axis;

an outer structure continuously disposed along the outer periphery; and

a first intermediate member radially disposed about a line intersecting the optical axis and extending between and operably coupled to the optic and the outer structure;

wherein the outer structure includes first and second weakened regions disposed on opposite sides of the line.

15. The intraocular lens of claim 14 , wherein the outer structure is elliptical.

21. The intraocular lens of claim 16 , wherein the outer structure is made of a first material and at least one of the weakened regions is made of a second material that is more bendable than the first material.

22. An intraocular lens for insertion into the capsular bag of an eye, comprising:

an optic disposed about an optical axis;

a support structure disposed about the optic, comprising:

an outer periphery defined by an intersection of a maximum outer radial extent of the support structure and a plane perpendicular to the optical axis;

an outer structure comprising a first elongate element having a first weakened region and a second elongate element having a second weakened region, each elongate element being continuously disposed along the outer periphery; and
