Abstract

An accommodating intraocular lens for providing a range of accommodative vision contains an optic and a haptic. The optic is disposed about an optical axis and includes an anterior surface and a posterior surface defining a clear aperture of the optic. The haptic is at least partially disposed inside the optic and includes an inner structure, an outer structure, and a plurality of arms disposed between and connecting the inner structure and the outer structure. The inner structure is circumferentially disposed about the optical axis, while the outer structure is circumferentially disposed about the inner structure and has an outer face. Each arm has proximal portion adjacent the inner structure and a distal portion adjacent the outer structure that is bifurcated in a radial direction from the proximal portion. The intraocular lens also has an outer surface defined by outer surfaces of the plurality of arms and an outer surface of the outer structure. The inner structure and at least a portion of the arms are disposed inside the clear aperture. The distal portion of each arm has a larger axial extent than an axial extent of the inner portion. The distal portion of each arm has a larger axial extent along the outer surface than an axial extent of the outer structure along the outer surface.

First claim

What is claimed:

1. An intraocular lens, comprising:
an optic disposed about an optical axis including an anterior surface and a posterior surface defining an optic plane therebetween that is substantially perpendicular to the optical axis;
a haptic at least partially disposed inside the optic comprising:
an inner structure circumferentially disposed about the optical axis and lying substantially within the optic plane;
an outer structure configured to engage a capsular bag, the outer structure circumferentially disposed about the optical axis and lying substantially within the optic plane; and
a plurality of arms disposed between and connecting the inner structure and the outer structure having a proximal portion adjacent the inner structure and distal portions extending away from the inner structure and adjacent the outer structure, the distal portions at least partially bounding an area of reduced thickness of the haptic between the distal portions;
wherein the distal portions of each of the arms have a larger axial extent than an axial extent of the proximal portion of each of the arms, and
wherein each distal portion of each arm comprises a first arcuate portion and a second arcuate portion, the first and second arcuate portions extending in anterior and posterior directions parallel to the optical axis, the first and second arcuate portions each having a convex arcuate shape in a plane parallel to and passing through the optical axis.

2. The intraocular lens of claim 1 , wherein the inner structure is comprised of a continuous ring about the optical axis.

3. The intraocular lens of claim 1 , wherein the arms are bifurcated in a radial direction away from the proximal portion.

4. The intraocular lens of claim 1 , wherein the outer structure is comprised of a plurality of arcuate ribbons connecting adjacent arms of the plurality of arms.

5. The intraocular lens of claim 1 , wherein the first and second arcuate portions at least partially bound an opening.

6. The intraocular lens of claim 1 , where at least a portion of the arms is disposed inside the optic.
