Patent number: 9220590Abstract: The present invention provides an accommodative intraocular lens (AIOL) system and method for improving accommodation with an intraocular lens. The method involves insertion into the capsular bag of a flexible optic holder comprising a plurality of haptics configured to allow the capsular bag to be sectioned at regular intervals following fusion of the capsular bag. The haptics of the optic holder are designed to allow maximum fusion of the anterior and posterior leaves of the capsular bag following placement of the optic holder in the capsular bag. Following introduction of the optic holder into the capsular bag, the natural or assisted process of fibrosis/fusion of the capsular bag occurs, thereby sealing and securely capturing the haptics within the capsular bag.Type: GrantFiled: June 10, 2011Date of Patent: December 29, 2015Assignee: Z Lens, LLCInventor: Paul Marius Beer

Publication number: 20140058507Abstract: Described herein are intraocular lenses and methods of implantation. In one aspect, the lens includes a shape changing optical element; a force translation element having a first end region coupled to the optical element and a second end region extending towards a ciliary structure, and an attachment portion coupled to the second end region of the force translation element and configured to contact the ciliary structure. The force translation element is configured to functionally transmit movements of the ciliary structure into a force exerted upon the optical element to effect an accommodating and a disaccommodating change of the optical element.Type: ApplicationFiled: October 30, 2013Publication date: February 27, 2014Applicant: FORSIGHT LABS, LLCInventors: Cary Reich, Eugene de Juan, JR., Yair Alster

Patent number: 8657878Abstract: This invention relates to intraocular lenses. More particularly, this invention relates to intraocular lenses that have the ability to alter the light refractive power in response to changes in the tension of the ciliary muscle or ciliary body of the eye or any other accommodative forces. Lenses of this invention are generally referred to as interfacial, i.e., lens properties being defined as the interface of two liquids having different refractive indices, refractive accommodating lenses (IRAL).Type: GrantFiled: February 18, 2010Date of Patent: February 25, 2014Assignee: Hoya CorporationInventors: Khalid Mentak, Beda Steinacher, Philipp Stücklin, Hans Flückiger

Patent number: 8647384Abstract: An accommodating intraocular lens includes an adjustable optic, wherein the optic is capable of being moved between an accommodated state and an unaccommodated state. The optic includes an anterior portion, a posterior portion, and a sidewall between the anterior portion and the posterior portion. The lens further includes a ring disposed about the optic sidewall and a haptic coupled to the ring. The haptic is capable of being coupled to a patient's capsular bag. A method for implanting an accommodating intraocular lens is also provided.Type: GrantFiled: November 10, 2010Date of Patent: February 11, 2014Inventor: Kenneth L. Lu

Patent number: 8647383Abstract: An intraocular lens in which deterioration in contrast is suppressed even when the optical axis of the intraocular lens is decentered from the optical axis of the eyeball when the intraocular lens is inserted into the eye while the advantage of a conventional aberration reduction type intraocular lens that the image is seen clearly is sustained by employing such a power distribution as respectively having at least one positive power deviation region (E1) having a power larger than that represented by the reference power distribution and at least one negative power deviation region (E2) having a power smaller than that represented by the reference power distribution in the central region of the intraocular lens assuming that a power distribution being set to cancel the spherical aberration of cornea when the intraocular lens is inserted into the eye is the reference power distribution.Type: GrantFiled: May 31, 2007Date of Patent: February 11, 2014Assignee: Hoya CorporationInventors: Demas Sanger, Tjundewo Lawu
