"Over the last ten years, the Malyugin Ring has become the standard of care for pupil management. When MST set out to redesign the Malyugin Ring Classic, we established three goals: improve or maintain the safety of the device, increase the ease of placement and removal from the pupil margin, and allow for ready entry in 2.0mm incisions.\r\n\r\nAfter several years of research and development, we are proud to introduce the Malyugin Ring 2.0. We believe surgeons will find the Malyugin Ring 2.0 is even gentler, even easier to use, and requires no change in surgical technique."
