Publication number: 20110054601Abstract: An accommodating intraocular lens (aIOL) is disclosed, with an optic that changes shape in response to an ocular force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. A surface adherent improves the accommodative performance of the haptic, such that compressive/tensile forces may be more efficiently transferred from the haptic to optic. One way to enhance force transfer is to provide a surface layer of an adhesive to the haptic and/or optic, for instance a reversible bioadhesive material. Or, portions of the exterior surface of the IOL may have microfibers thereon that mimic the adhesive properties of Gecko feet. Another aspect is application of a reversible bioadhesive material to the interior of the empty capsular bag prior to introduction of an injectable polymer IOL.Type: ApplicationFiled: August 27, 2010Publication date: March 3, 2011Applicant: Abbott Medical Optics Inc.Inventors: Kenneth E.
