Abstract
An intraocular lens includes a substantially circular lens element formed of a transparent material and one or more haptics extending outwardly from an outer edge of the lens element. The one or more haptics are formed of a polymer foam material having a negative Poisson's ratio (NPR) and are configured to couple the intraocular lens to an eye of a patient. The lens includes an inner region having a first index of refraction and an outer region disposed circumferentially surrounding the inner region, the outer region having a second index of refraction different from the first index of refraction.

An intraocular lens comprising:
- a substantially circular lens element formed of a transparent material;
- and
- one or more haptics extending outwardly from an outer edge of the lens element, the entirety of each of the one or more haptics formed of a polymer foam material having a negative Poisson's ratio (NPR), in which the one or more haptics are configured to couple the intraocular lens to an eye of a patient.
