Patent number: 11931248Abstract: An IOL system includes a capsular ring having a concave exterior surface extending around its circumference that is configured, upon insertion into a capsular bag of a patient's eye, to engage an equatorial region of the capsular bag. The concave exterior surface extends between an anterior surface and a posterior surface of the capsular ring. A first one or more flaps are arranged on the anterior surface such that at least a portion of each of the first one or more flaps, upon insertion into the capsular bag of a patient's eye, engages an anterior portion of the capsular bag. Similarly, a second one or more flaps are arranged on the posterior surface such that at least a portion of each of the second one or more flaps, upon insertion into a capsular bag of a patient's eye, engages a posterior portion of the capsular bag.Type: GrantFiled: September 9, 2020Date of Patent: March 19, 2024Assignee: Alcon Inc.Inventors: Stephen Collins, Niranjana Nandakumar, John Radle, Stephen Van Noy, Douglas B.

Patent number: 9078744Abstract: A single-optic accommodative lens system includes two intraocular elements designed to be located within the capsular bag to extend depth of focus and/or restore accommodation following cataract extraction of a natural lens. A first intraocular element comprises a circumferential capsular ring having interlock features to couple to and control the dynamic vault response of a second intraocular element. This second intraocular element comprises an intraocular lens (IOL) having an optic and a plurality of haptics and is designed to move axially in response to changes in the geometry of the eye capsule and thus provide a range of accommodative power. The IOL further comprises interlock features complementary to the interlock features of the first intraocular element for coupling the IOL to the capsular ring in a manner that provides for controlled movement of the IOL in response to capsular forces.Type: GrantFiled: February 3, 2010Date of Patent: July 14, 2015Assignee: NOVARTIS AGInventor: Stephen Van Noy

Patent number: 8858626Abstract: A two-optic accommodative lens system is disclosed. Two coupled lenses are located within the capsular bag to extend depth of focus and/or restore accommodation following extraction of a natural lens. The first lens comprises a spring-like structure attaching an optic to a ring-like support structure. The optic can be a monofocal or multifocal optical element having a positive or negative power. The first lens further comprises features designed to couple the ring-like structure to a second lens. The first lens can be located anteriorly within the capsular bag. The second lens is located posteriorly to the first lens within the capsular bag and can have an opposite or supplementary power to that of the first lens. The second lens can also be a monofocal or multifocal lens and comprises a plurality of haptics which can be used to size the lens system over a range of capsular bag sizes. The second lens further comprises features for coupling the second lens to the ring-like structure of the first lens.Type: GrantFiled: February 4, 2010Date of Patent: October 14, 2014Assignee: Novartis AGInventor: Stephen Van Noy

Publication number: 20060244904Abstract: In one aspect, the present invention provide an ophthalmic lens (e.g., an IOL) that includes an optic having an anterior optical surface and a posterior optical surface, where the optic provides an optical power in a range of about 16 D to about 25 D as measured in a medium having an index of refraction substantially similar to that of the eye's aqueous humor (e.g., about 1.336). At least one of the optical surfaces is characterized by an aspherical base profile such that the optic exhibits a negative spherical aberration in a range of about ?0.202 microns to about ?0.190 microns across the power range.Type: ApplicationFiled: April 4, 2006Publication date: November 2, 2006Inventors: Xin Hong, Jihong Xie, Stephen Van Noy, Dan Stanley, Mutlu Karakelle, Xiaoxiao Zhang, Michael Simpson

Publication number: 20060227286Abstract: The present invention provides an ophthalmic lens (e.g., an intraocular lens) having an optic with an anterior surface and a posterior surface, which exhibits a shape factor (defined as a ratio of the sum of the anterior and posterior curvatures to the difference of such curvatures) in a range of about ?0.5 to about 4. In a related aspect, the shape factor of the optic lies in a range of about 0 to about 2. The above shape factors give rise to a plurality of different lens shapes, such as concave-convex, plano-convex and plano-concave.Type: ApplicationFiled: April 4, 2006Publication date: October 12, 2006Inventors: Xin Hong, Stephen Van Noy, Jihong Xie, Dan Stanley, Mutlu Karakelle, Michael Simpson, Xiaoxiao Zhang
