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.
Claims22
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 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.
A method of implanting an intraocular lens in an eye of a patient, the method comprising:
- creating an incision in an cornea of the eye of the patient;
- inserting the intraocular lens into the eye of the patient through the incision in the cornea;
- and
- securing the intraocular lens in the eye such that a substantially circular, transparent lens element of the intraocular lens is disposed along an optical axis of the eye and one or more haptics of the intraocular lens are in contact with tissue of the eye,
- in which the one or more haptics are formed of a polymer foam material having a negative Poisson's ratio.
