Publication number: 20230381018Abstract: A ring that can maintain a pupil in an extended position during an ophthalmic procedure. The ring has a plurality of loops that capture iris tissue. The ring is configured to extend the pupil when iris tissue is inserted into each loop. An ophthalmic procedure such as phacoemulsification can then be performed on the patient. The ring has a center opening that provides a wide view of the ocular chamber during the procedure.Type: ApplicationFiled: March 9, 2023Publication date: November 30, 2023Inventors: Boris Malyugin, Vaclav Dusek, Lawrence Laks

Patent number: 11602456Abstract: A method of implanting a continuous iris-expanding ring in an eye involves ejecting the continuous iris-expanding ring from a distal end of a cannula toward an iris of the eye, securing a distal portion of the continuous iris-expanding ring device ring to the iris of the eye, and securing a proximal portion of the continuous iris-expanding ring to the iris of the eye. The continuous iris-expanding ring is in a collapsed configuration in the cannula prior to being ejected and in an expanded configuration when the proximal portion and the distal portion of the continuous iris-expanding ring are secured to the iris of the eye and extend across the pupil.Type: GrantFiled: January 17, 2020Date of Patent: March 14, 2023Assignee: MicroSurgical Technology, Inc.Inventors: Boris Malyugin, Vaclav Dusek, Lawrence Laks

Publication number: 20220152289Abstract: An ophthalmic irrigator-aspirator has a handpiece with aspiration and irrigation openings through its distal end. A tip component connects to the handpiece and has an aspiration cannula. A flexible sleeve has an annular hub for watertight connection to the handpiece or a base portion of the tip. The sleeve has an intermediate portion that forms a channel for an irrigation fluid along the exterior of the cannula to an irrigation port in the sleeve. The distal end portion of the sleeve is sized for a watertight connection over the distal portion of the cannula. Such distal end portion of the sleeve has an aspiration port in communication with the cannula aspiration port. The sleeve proximate, intermediate, and distal portions are integral with each other and are formed of a resilient material that allows the sleeve to be tightly fitted on the handpiece or tip base portion and the cannula.Type: ApplicationFiled: August 23, 2021Publication date: May 19, 2022Inventors: Kenneth J. Wiljanen, Robert May, Lawrence Laks
