Accommodating intraocular lens system with enhanced range of motion
First Claim
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 extending radially outward from the anterior optic, 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, wherein the posterior optic contacts the at least two anterior haptic arms inward of the second end of each anterior haptic arm towards the anterior optic; 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.

Abstract
An intraocular lens system adapted to be implanted within an eye includes an anterior optic movable in a forward direction within the eye. The intraocular lens system further includes 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. The intraocular lens system further includes a posterior optic movable in the forward direction within the eye and coupled to the anterior haptic arms. The intraocular lens system further includes at least one posterior haptic member adapted to be coupled to the eye and coupled to the posterior optic. 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 substantially larger than the first forward movement.
