Lenses disclosed herein are referred to as accommodating lenses.
Claims12
An intraocular lens comprising:
- an optical element adapted to be implanted within a human eye, wherein the optical element has a posterior lens forming a refractive surface with a positive diopter and a gas chamber containing gas adjacent to a polymeric membrane forming a refractive surface of a negative power.
A lens for implantation in the human eye comprising a refractive surface with a positive diopter and a gas chamber containing gas adjacent to a polymeric membrane forming a refractive surface of a negative power.
An accommodating intraocular lens assembly for implantation into a generally circular inner surface of an eye, comprising:
- (a) a lens body having an optic and having at least two optic hinge portions, a polymeric membrane and a gas chamber containing gas, wherein the gas chamber is adjacent to the polymeric membrane;
- (b) at least two haptics, each haptic having a haptic hinge portion pivotally connected to said optic hinge portions, said haptics spaced apart from each other generally radially away from the optic, adapted to engage the generally circular inner surface of the eye for holding the lens in the eye.
