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 is:

1. An intraocular lens, comprising:
an optic disposed about an optical axis including an anterior surface and a posterior surface defining a clear aperture of the optic; and
a haptic attached to the optic, comprising:
an inner structure circumferentially disposed about the optical axis;
a plurality of arms having a proximal portion coupled to the inner structure and a distal portion extending away from the inner structure, wherein the plurality of arms are connected together via a series of arcuate ribbons, wherein each ribbon extends between each pair of adjacent arms at the distal portion, and further wherein each ribbon is curved outwardly away from the optic axis such that a portion of each ribbon between each pair of adjacent arms is disposed at a greater radial distance from the optical axis than a portion of the ribbon coupled to an arm;
wherein the distal portion of each arm has a larger axial extent than an axial extent of the proximal portion of each arm.

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

3. The intraocular lens of claim 1 , wherein the inner structure and at least a portion of the arms are disposed inside the optic.

4. An intraocular lens, comprising:
an optic disposed about an optical axis including an anterior surface and a posterior surface defining a clear aperture of the optic; and
a haptic, attached to the optic, comprising:
an inner structure circumferentially disposed about the optical axis; and
a plurality of arms having a proximal portion adjacent to the inner structure and a distal portion extending away from the inner structure, wherein the plurality of arms are connected together via a series of arcuate ribbons, wherein each ribbon extends between each pair of adjacent arms at the distal portion, and further wherein each ribbon is curved outwardly away from the optic axis such that a portion of each ribbon between each pair of adjacent arms is disposed at a greater radial distance from the optical axis than a portion of the ribbon coupled to an arm;
wherein the distal portion of each arm has a larger axial extent than an axial extent of the proximal portion of each arm.

5. The intraocular lens of claim 4 , wherein the inner structure is continuous about the optical axis and is configured to maximize the transfer of deforming force from the arms to the optic.

6. The intraocular lens of claim 4 , wherein the arms are bifurcated in a radial direction away from the proximal portion.
