Patent number: 10420639Abstract: A foldable intraocular lens for providing vision contains an optic body that includes an optical zone and a peripheral zone entirely surrounding the optical zone. The optic body has an anterior face, a substantially opposing posterior face, an optic edge, and an optical axis. The anterior face comprises a central face, a peripheral face, and a recessed annular face therebetween that is disposed posterior to the peripheral face. The intraocular lens further comprises at least one haptic that is integrally formed with the peripheral zone. The haptic comprises a distal posterior face, a proximal posterior face, and a step edge disposed at a boundary therebetween. The haptic further comprises a side edge disposed between the optic edge and the step edge. The proximal posterior face and the posterior face of the optic body form a continuous surface. An edge corner is formed by the intersection of the continuous surface with the optic edge, the side edge, and the step edge.Type: GrantFiled: July 23, 2018Date of Patent: September 24, 2019Assignee: Johnson & Johnson Surgical Vision, Inc.Inventors: Jim Deacon, David J.

Patent number: 8657876Abstract: Apparatus and methodology for inserting an intraocular lens (IOL) into an eye. The apparatus includes a cartridge for holding an IOL and a handpiece with a body member for receiving the cartridge, an injector rod that is receivable by the body member, and a drive mechanism that longitudinally oscillates the injector rod in the body member when a rotational force is applied about a longitudinal axis in a single direction. In other words, a constant rotation in a single direction of the drive mechanism causes the injector rod to move distally and proximally in discrete increments, with the distal increments being larger than the proximal increments. Accordingly, the injector rod urges an IOL out of the handpiece in a two-steps-forward, one-step-back manner, thereby minimizing or eliminating the chance of the injector rod engaging with the IOL.Type: GrantFiled: February 7, 2011Date of Patent: February 25, 2014Assignee: Abbott Medical Optics, Inc.Inventor: David J.

Patent number: 8635541Abstract: The present invention provides a mechanism to display exactly which parts of a GUI are being updated by non-blocking or asynchronous interaction with a server. It also allows the user to continue to interact with unaffected portions of the display and therefore can be used to provide a superior user experience. Specifically, the present invention displays a busy or progress indicator at the element level of granularity, indicating that the value of the element is currently undergoing a non-blocking or asynchronous update.Type: GrantFiled: December 6, 2007Date of Patent: January 21, 2014Assignee: International Business Machines CorporationInventors: David J.
