Patent number: 11696823Abstract: A virtual aperture integrated into an intraocular lens is disclosed. Optical rays which intersect the virtual aperture are widely scattered across the retina causing the light to be virtually prevented from reaching detectable levels on the retina. The use of the virtual aperture helps remove monochromatic and chromatic aberrations yielding high-definition retinal images. For a given definition of acceptable vision, the depth of field is increased over a larger diameter optical zone. In addition, thinner intraocular lenses can be produced since the optical zone can have a smaller diameter. This in turn allows smaller corneal incisions and easier implantation surgery.Type: GrantFiled: June 21, 2019Date of Patent: July 11, 2023Assignee: Z Optics, Inc.Inventors: Edwin J. Sarver, James J.

Patent number: 9681945Abstract: A Double Accommodating Intraocular Lens (DAIOL), which not only axially moves its flexible optic to accommodate, but also peripherally compresses or decompresses the optic to change its convexity or power, thus, double accommodating simultaneously upon contraction or expansion of the ciliary muscles and subsequently the lens capsule. The DAIOL includes a deployable semi-rigid or elastic haptic assembly and a flexible single optic. The DAIOL is further composed of three or four ring haptics and three or four deployable resilient lazy tongs, attached to a single elastically flexible plate encompassing a flexible optic. Accordingly, the radial compression of the capsular bag by the contraction of the ciliary muscles axially moves and radially compresses the flexible optic in the lens and vice versa upon radial expansion of the capsular bag, backward axial movement, and decompression of the optic, due to the resilient lazy tongs action, for double accommodation.Type: GrantFiled: September 15, 2015Date of Patent: June 20, 2017Inventors: Mohsen Shahinpoor, David P. Soltanpour

Patent number: 9622852Abstract: A novel lens for variable focus has two optical elements which simultaneously move in a lateral and an axial direction. The lens also includes variable corrective optics to correct for undesired variable optical aberrations. The lens can be used as an accommodating lens for implantation in the capsular bag. The lens can be driven by either the surfaces of the capsular bag as well as the rim of the capsular bag.Type: GrantFiled: October 29, 2010Date of Patent: April 18, 2017Assignee: Akkolens International B.V.Inventors: Aleksey Nikolaevich Simonov, Michiel Christiaan Rombach

Patent number: 9517127Abstract: A prosthetic capsular device configured to be inserted in an eye includes a housing structure and a ring structure. The housing structure includes a first side, a second side opposite the first side, a third side, a fourth side opposite the third side, a posterior side including a refractive surface, an anterior side opposite the posterior side, and a longitudinal axis. The first side, the second side, the third side, the fourth side, the posterior side, and the anterior side at least partially define a cavity configured to contain an intraocular device (e.g., an IOL). The anterior side includes an opening. The ring structure includes a ring structure portion extending radially outward from proximate one of an end of the first side and an end of the second side.Type: GrantFiled: April 26, 2016Date of Patent: December 13, 2016Assignee: Omega Ophthalmics LLCInventors: Gary N. Wortz, Rick William Ifland

Patent number: 9339375Abstract: Disclosed herein is an implantable capsule expander device for insertion within a lens capsule of an eye of a patient. The device comprises an arcuate center portion including first and second rims and having a first height, an outermost peripheral portion including a second height that is less than the first height, and a receiving portion formed between the first and second rims. The center portion and the outermost peripheral portion are configured to stabilize the capsule expander device within the lens capsule and to expand the lens capsule. The receiving portion is sized to receive an artificial intraocular lens.Type: GrantFiled: December 11, 2013Date of Patent: May 17, 2016Assignee: Novartis AGInventors: Sung Kyu Lee, Son Trung Tran, Kevin Mark Lewellen

Patent number: 9339373Abstract: A polymeric material with a molecular response time that makes it suitable for use near fragile body tissues. The polymeric material is useful for both low modulus and high modulus applications thereby simplifying the multi-part polymeric article manufacturing process and creating better integrated multi-part polymeric articles. Cross-linked polymers with different moduli may be obtained utilizing the same or similar starting materials but modifying the amount of catalyst, the amount of cross-linking agent, and/or the amount of methyl vinyl cyclics.Type: GrantFiled: March 28, 2012Date of Patent: May 17, 2016Assignee: Abbott Medical Optics Inc.Inventors: Can B. Hu, Michael D. Lowery
