Patent number: 11622887Abstract: Devices, systems, and methods for performing an ophthalmic procedure in an eye are disclosed. The devices include a hand-held portion and a distal, elongate member coupled to the hand-held portion having a lumen operatively coupled to a vacuum source. A drive mechanism operatively coupled to the elongate member is configured to oscillate the elongate member. When in use, the device is configured to aspirate ocular material from the eye through the lumen. The drive mechanism retracts the elongate member with a retraction speed profile and advances the elongate member with an extension speed profile. The retraction speed profile is different from the extension speed profile.Type: GrantFiled: June 10, 2019Date of Patent: April 11, 2023Assignee: Carl Zeiss Meditec Cataract Technology Inc.Inventors: Scott Chamness, Luke W.
