Publication number: 20240148490Abstract: The present disclosure provides an ophthalmic lens (such as an IOL) that is designed to enhance depth of focus for intermediate vision performance, while maintaining distance vision. The lens may include an optic having an anterior surface and a posterior surface disposed about an optical axis. One of the surfaces (e.g., the anterior surface) may have a surface profile involving a superposition of at least three structures or profiles, including a base structure, a phase shift structure having an inner region, an outer region and a transition region, and a zonal structure having an inner power zone and an outer transition zone.Type: ApplicationFiled: January 9, 2024Publication date: May 9, 2024Inventors: Myoung-Taek CHOI, Sangyeol LEE, Shinwook LEE, Wangkuen LEE

Patent number: 11963867Abstract: The present disclosure concerns a curvature-changing, accommodative intraocular lens (IOL) for implantation in the capsular bag of a patient's eye. The IOL includes a fluid optic body having a cavity for containing an optical fluid, the cavity at least partially defined by a sidewall extending around the cavity and defining a diameter of the cavity and a deformable optical membrane intersecting the sidewall around a circumference of the sidewall and spanning the diameter of the cavity. The IOL further includes a second optic body spaced a distance apart from the fluid optic body and a plurality of struts extending from the sidewall and coupling the fluid optic body to the second optic body. The struts are configured such that axial compression of the capsular bag causes the struts to deform the sidewall in a manner that increases the diameter of the cavity, modifying a curvature of the deformable optical membrane.Type: GrantFiled: August 5, 2021Date of Patent: April 23, 2024Assignee: Alcon Inc.Inventors: David Borja, Lauren Gerardi, Shinwook Lee

Patent number: 11944535Abstract: A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having anterior surface, a posterior surface and at least one diffractive structure including a plurality of zones. The at least one diffractive structure is for at least one of the anterior surface and the posterior surface. Each zone includes at least one echelette having a least one step height. The step height(s) are individually optimized for each zone. To compensate chromatic aberration of eye from distance to a range of vision, a greater than 2? phase step height may be employed and the step height(s) folded by a phase, which is an integer multiple of two multiplied by ?. Hence chromatic aberration of eye may be compensated to improve vision from distance to near.Type: GrantFiled: May 17, 2022Date of Patent: April 2, 2024Assignee: Alcon Inc.Inventors: Xin Hong, Shinwook Lee

Publication number: 20220401212Abstract: The present disclosure provides an ophthalmic lens that is disposed to balance coma aberrations if the lens, when inserted in a patient's eye, is decentered or tilted with respect to an optical axis of the patient's eye, and maintain a substantially diffraction-limited image quality if the lens, when inserted in the patient's eye, is centered with respect to the optical axis of the patient's eye. The lens may include an optic having an anterior surface and an opposing posterior surface disposed about an optical axis of the lens. One of the surfaces (e.g., the anterior surface) may have a semi-aspheric surface profile, which includes an inner region having a substantially spherical surface profile and extending radially from the optical axis of the lens to a first boundary, and an outer region having an aspherical surface profile and extending radially at least beyond the first boundary to a second boundary.Type: ApplicationFiled: May 26, 2022Publication date: December 22, 2022Inventors: Jeffrey Ryan Lutkenhaus, Shinwook Lee, Sangyeol Lee, Daniel Robert Carson, Zaiwei Xu
