Abstract

An accommodating intraocular lens includes an optic and four haptics. the optic includes an outer wall, a solid posterior optic, an anterior fluid chamber, an anterior membrane and a fluid reservoir within the outer wall surrounding the anterior fluid chamber and the solid posterior optics. The four haptics are attached to the outer wall at four attachment points. Each of the four haptics includes an arc member extending between successive attachment points and contacting the outer wall only at the attachment points. Each of the arc members is configured to compress laterally under accommodative forces.

First claim

What is claimed is:

1. An accommodating intraocular lens, comprising:
an optic comprising an outer wall, a solid posterior optic, an anterior fluid chamber, an anterior membrane and a fluid reservoir within the outer wall surrounding the anterior fluid chamber and the solid posterior optic; and
four haptics each attached to the outer wall at two attachment points, each of the four haptics comprising an arc member extending between the two attachment points and contacting the outer wall only at the two attachment points, each arc member configured to compress laterally under accommodative forces.

2. The lens of claim 1 , wherein the outer wall of the optic is octagonal and comprises eight planar surfaces, the two attachment points for each of the four haptics connecting to different ones of the eight planar surfaces.

3. The lens of claim 1 , wherein the solid posterior optic is plano-convex.

4. The lens of claim 1 , wherein the fluid reservoir and the anterior fluid chamber are connected by at least one fluid channel.
