Claims
- 1. An intraocular lens system adapted to be implanted within an eye, the intraocular lens system comprising:
an anterior optic movable in a forward direction within the eye; at least two anterior haptic arms, each anterior haptic arm having a first end coupled to the anterior optic and a second end adapted to be coupled to the eye; a posterior optic movable in the forward direction within the eye and coupled to the anterior haptic arms; and at least one posterior haptic member adapted to be coupled to the eye and coupled to the posterior optic, wherein the anterior haptic arms are responsive to a first forward movement of the posterior optic by actuating a second forward movement of the anterior optic, the second forward movement substantially larger than the first forward movement.
- 2. The intraocular lens system of claim 1, wherein the second end of each anterior haptic arm is adapted to be coupled to the capsular bag of the eye.
- 3. The intraocular lens system of claim 1, wherein the posterior haptic member is adapted to be coupled to the capsular bag of the eye.
- 4. The intraocular lens system of claim 1, wherein the second end of each anterior haptic arm is adapted to be coupled to the zonular fibers of the eye.
- 5. The intraocular lens system of claim 1, wherein the posterior haptic member is adapted to be coupled to the zonular fibers of the eye.
- 6. The intraocular lens system of claim 1, wherein the anterior optic and the posterior optic are movable within the capsular bag of the eye.
- 7. The intraocular lens system of claim 1, wherein the posterior optic comprises an edge, wherein the edge engages at least one anterior haptic arm.
- 8. The intraocular lens system of claim 1, wherein the posterior optic comprises at least two grooves, wherein each groove engages at least one anterior haptic arm.
- 9. The intraocular lens system of claim 1, wherein the anterior optic rotates about an axis in response to the first forward movement of the posterior optic.
- 10. The intraocular lens system of claim 1, wherein the first forward movement and the second forward movement result in a change of power of the intraocular lens system of between approximately 10 diopters and approximately 30 diopters.
- 11. The intraocular lens system of claim 1, wherein the first forward movement and the second forward movement result in a change of power of the intraocular lens system of approximately 20 diopters.
- 12. The intraocular lens system of claim 1, comprising a pair of posterior haptic members positioned substantially symmetrically to the posterior optic.
- 13. An intraocular lens system comprising:
a posterior optic adapted to move a first distance in a forward direction; and an anterior optic coupled to the posterior optic, the anterior optic adapted to move a second distance in the forward direction in response to the first distance movement of the posterior optic, wherein the second distance is larger than the first distance.
- 14. An intraocular lens system comprising:
a posterior optic adapted to move a first distance in a forward direction; and an anterior optic adapted to move a second distance in the forward direction, wherein the second distance is larger than the first distance.
- 15. A method of facilitating accommodative motion in an intraocular lens system, said method comprising:
translating forward movement of a posterior optic of the intraocular lens system into forward movement of an anterior optic of the intraocular lens system, thereby providing ocular accommodation.
