Abstract
An intraocular lens (IOL) with a shape-changing optic is provided. The shape-changing optic includes an elastic anterior face located anterior to the equator. The anterior face has an anterior surface, a posterior surface, and a periphery. The shape-changing optic also includes a posterior face having an anterior surface, a posterior surface, and a periphery. An elastic side wall can extend across the equator and extend from the anterior face to the posterior face. A chamber can be located between the anterior face and the posterior face. The IOL can further include at least one haptic extending from the periphery of the anterior face, the periphery of the posterior face, or both.
Claims20
An intraocular lens (IOL) comprising a shape-changing optic, the IOL configured to assume an accommodated state, a dis-accommodated state, and states therebetween, the IOL comprising:
- an elastic anterior face located anterior to the equator, having an anterior surface, a posterior surface, and a periphery;
- a posterior face located posterior to the equator, having an anterior surface, a posterior surface, and a periphery;
- an elastic side wall extending across the equator and extending from the anterior face to the posterior face;
- a chamber located between the anterior face and the posterior face and containing a material;
- and
- at least one haptic having a medial portion and a lateral portion, the medial portion extending directly or indirectly from the periphery of the anterior face, the periphery of the posterior face, or both, wherein the anterior face is more resistant to deformational change than the material contained within the chamber.
An intraocular lens (IOL) comprising a shape-changing optic, the IOL configured to assume an accommodated state, a dis-accommodated state, and states therebetween, the IOL comprising:
- an elastic anterior face located anterior to the equator, having an anterior surface, a posterior surface, and a periphery;
- a posterior face having an anterior surface, a posterior surface, and a periphery;
- an elastic side wall extending across the equator and extending from the anterior face to the posterior face;
- an expandable chamber located between the anterior face and the posterior face, the expandable chamber containing a material and having an integrated haptic comprising ridges on the respective periphery of the anterior face and/or the periphery of the posterior face, wherein the anterior face is more resistant to deformational change than the material contained within the chamber.
