Claims
- 1. An accommodating intraocular lens for implantation in an eye having an optical axis, said lens comprising:
an anterior portion comprising:
an anterior viewing element comprised of an optic having refractive power; an anterior biasing element comprising first and second anterior translation members extending from the anterior viewing element; a posterior portion comprising:
a posterior viewing element in spaced relationship to said anterior viewing element; a posterior biasing element comprising first and second posterior translation members extending from the posterior viewing element; said anterior portion and posterior portion meeting at first and second apices of said intraocular lens such that a plane perpendicular to the optical axis and passing through said apices is closer to one of said viewing elements than to the other of said viewing elements, said anterior portion and said posterior portion being responsive to force thereon to cause the separation between said viewing elements to change.
- 2. The lens of claim 1, wherein said plane passing through said apices is closer to the posterior viewing element than to the anterior viewing element.
- 3. The lens of claim 1, wherein said plane passing through said apices is closer to the anterior viewing element than to the posterior viewing element.
- 4. The lens of claim 1, wherein said first and second anterior translation members extend from respective sides of said anterior viewing element.
- 5. The lens of claim 4, wherein said first and second posterior translation members extend from respective sides of said posterior viewing element.
- 6. The lens of claim 1, wherein said first and second anterior translation members extend from respective opposite sides of said anterior viewing element.
- 7. The lens of claim 6, wherein said first and second posterior translation members extend from respective opposite sides of said posterior viewing element.
- 8. The lens of claim 1, wherein said first anterior translation member forms a first anterior biasing angle with respect to said plane as said lens is viewed from the side and said first posterior translation member forms a first posterior biasing angle with respect to said plane as said lens is viewed from the side, and wherein said first anterior biasing angle and said first posterior biasing angle are unequal.
- 9. The lens of claim 8, wherein said first anterior biasing angle is larger than said first posterior biasing angle.
- 10. The lens of claim 8, wherein said first posterior biasing angle is larger than said first anterior biasing angle.
- 11. The lens of claim 8, wherein said second anterior translation member forms a second anterior biasing angle with respect to said plane as said lens is viewed from the side and said second posterior translation member forms a second posterior biasing angle with respect to said plane as said lens is viewed from the side, and wherein said second anterior biasing angle and said second posterior biasing angle are unequal.
- 12. The lens of claim 1, wherein said anterior viewing element has a periphery and said posterior viewing element has a periphery, and wherein each of said translation members is attached to one of said viewing elements at at least one attachment location, all of the attachment locations being significantly further away from the apices than the peripheries of the viewing elements are from the apices.
- 13. An accommodating intraocular lens for implantation in an eye having an optical axis, said lens comprising:
an anterior portion comprising:
an anterior viewing element comprised of an optic having refractive power; an anterior biasing element comprising first and second anterior translation members extending from the anterior viewing element; a posterior portion comprising:
a posterior viewing element in spaced relationship to said anterior viewing element; a posterior biasing element comprising first and second posterior translation members extending from the posterior viewing element; said anterior portion and posterior portion meeting at first and second apices of said intraocular lens, said anterior portion and said posterior portion being responsive to force thereon to cause the separation between said viewing elements to change; wherein said first anterior translation member forms a first anterior biasing angle, as said lens is viewed from the side, with respect to a plane perpendicular to the optical axis and passing through said apices, and said first posterior translation member forms a first posterior biasing angle, as said lens is viewed from the side, with respect to said plane, and wherein said first anterior biasing angle and said first posterior biasing angle are unequal.
- 14. The lens of claim 13, wherein said first anterior biasing angle is larger than said first posterior biasing angle.
- 15. The lens of claim 13, wherein said first posterior biasing angle is larger than said first anterior biasing angle.
- 16. The lens of claim 13, said second anterior translation member forms a second anterior biasing angle with respect to said plane as said lens is viewed from the side and said second posterior translation member forms a second posterior biasing angle with respect to said plane as said lens is viewed from the side, and wherein said second anterior biasing angle and said second posterior biasing angle are unequal.
- 17. The lens of claim 13, wherein said anterior viewing element has a periphery and said posterior viewing element has a periphery, and wherein each of said translation members is attached to one of said viewing elements at at least one attachment location, all of the attachment locations being further away from the apices than the peripheries of the viewing elements are from the apices.
