Publication number: 20260114989Abstract: A reversible intraocular lens (IOL) includes an anterior optical surface and a posterior optical surface. The anterior optical surface is configured to face a cornea of a user in a first orientation. The posterior optical surface is configured to face a cornea of a user in a second orientation. The reversible IOL provides a first spherical aberration correction in the first orientation and a second spherical aberration correction in the second orientation. The first spherical aberration correction is different from the second spherical aberration correction.Type: ApplicationFiled: October 30, 2025Publication date: April 30, 2026Inventors: Robert ANGELOPOULOS, Terah SMILEY, George PETTIT, Scott CHANDLER

Publication number: 20260024173Abstract: A method of augmenting an eye image includes obtaining a first training image of a first type and applying a first function to obtain a first generated image of a second type. A second function is applied to the first generated image to obtain a second generated image of the first type. A first loss function compares the first training image to the second generated image. The method also includes obtaining a second training image of the second type and applying the second function to obtain a first generated image of the first type. The first function is applied to the first generated image to obtain a second generated image having the second type. A second loss function compares the second training image to the second generated image. At least one of the first or second function are updated based on an output of the first and second loss functions.Type: ApplicationFiled: May 7, 2025Publication date: January 22, 2026Inventors: Sinchan BHATTACHARYA, Robert ANGELOPOULOS, Bryan Adams STANFILL, Shruti SIVA KUMAR, George Hunter PETTIT

Patent number: 11660182Abstract: Disclosed are adjustable accommodating intraocular lenses and methods of adjusting accommodating intraocular lenses post-operatively. In one embodiment, an adjustable accommodating intraocular lens comprises an optic portion and a peripheral portion. At least one of the optic portion and the peripheral portion can be made in part of a composite material comprising an energy absorbing constituent and a plurality of expandable components. At least one of a base power and a cylindricity of the optic portion can be configured to change in response to an external energy directed at the composite material.Type: GrantFiled: October 1, 2020Date of Patent: May 30, 2023Assignee: Alcon Inc.Inventors: Terah Whiting Smiley, Andrew R. Walz, Sharad Hajela, Gregory Vinton Matthews, Robert Angelopoulos, Nathan Lewis

Patent number: 11426270Abstract: An intraocular lens is disclosed that includes an optic body with a projection extending radially outwards from a peripheral surface of the optic body. The projection comprises a haptic contact surface facing radially outward, wherein the entire haptic contact surface is a flat surface. A haptic having a free distal end and a proximal portion is secured to the projection along the haptic contact surface, wherein the projection and the proximal portion interface at a butt joint without the haptic extending into the projection and without the projection extending into the haptic. The haptic also includes a haptic fluid chamber.Type: GrantFiled: November 7, 2016Date of Patent: August 30, 2022Assignee: Alcon Inc.Inventors: Daniel Hildebrand, Terah Whiting Smiley, Nathan Lewis, Robert Angelopoulos

Patent number: 9918831Abstract: Aspheric optical lenses (e.g., intraocular lenses and contact lenses) are provided. The intraocular lens includes a body portion defining an anterior optical surface and an opposing posterior optical surface. The anterior optical surface includes a central region surrounded by a first outer region and a second outer region. The central region has a first asphericity profile. The first outer region has a second asphericity profile that is different than the first asphericity profile of the central region. The second outer region has a third asphericity profile that is different than the second asphericity profile of the first outer region. The overall asphericity profile of the optical lens provides different depths of focus for different pupil sizes. The result is an optical lens that provides increased depth of focus or pseudo-accommodation while maintaining desired optical power and performance.Type: GrantFiled: December 12, 2011Date of Patent: March 20, 2018Assignee: Novartis AGInventors: Robert Angelopoulos, Stephen J. Van Noy

Patent number: 7998198Abstract: The present invention is generally directed to accommodative intraocular lenses (IOLs) that exhibit a dynamic spherical aberration as a function of accommodative power. By way of example, in one aspect, the present invention provides an intraocular lens (IOL) having an anterior optical element, a posterior optical element, and a mechanism for coupling the anterior and posterior elements so as to allow axial movement of those elements relative to one another for providing accommodation when the lens is implanted in a patient's eye. Each of the anterior and the posterior elements includes at least one aspherical surface, where the asphericities of the surfaces are adapted to provide a combined spherical aberration that varies with accommodation.Type: GrantFiled: February 4, 2009Date of Patent: August 16, 2011Assignee: Novartis AGInventors: Robert Angelopoulos, Xin Hong, Xiaoxiao Zhang, Mutlu Karakelle
