Designed by Boris Malyugin MD

(Cataract and Implant Surgery Department chief, deputy director (R&D, Edu) at the S.Fyodorov Eye Microsurgery Complex, Moscow), the Malyugin Ring has several advantages over traditional iris retractor hooks and other pupil dilating devices. Implantation and explantation are performed with an injector and are relatively simple.

As the device is implanted through the main port, additional incisions are not required making the procedure less traumatic and easier. It can be inserted through regular incisions as well as through the 1.6-1.8mm microincisions used in MICS with a wound- assisted technique of insertion and removal.

The unique design of the device provides eight points of pupillary margin fixation equating it to eight iris hooks.
