Malyugin Ring (MicroSurgical Technology)

Overcoming the small-pupil FLACS challenge with the Malyugin ringThe second-generation Malyugin ring is a versatile pupil expansion ring with high efficacy in femtosecond laser-assisted cataract surgery. Professor Boris Malyugin notes its advantages, having used it on a variety of classically difficult eyes and in complicated surgical cases.
Novel device designed for pupil enlargement, stabilization in IFIS eyes
Novel device designed for pupil enlargement, stabilization in IFIS eyesWisconsin ophthalmologist Gerald P. Clarke, MD, has developed a new horseshoe-shaped dilator for use during cases of intraoperative floppy iris syndrome.
Redesigned pupil expansion device reduces cataract surgery risksPre-treatment with the femtosecond laser in eyes undergoing cataract surgery can induce miosis. The use of a pupil expansion device, however, offers an effective method for managing small pupils in femtosecond laser-assisted cases whether the problem pre-exists or is caused by the laser, said Boris Malyugin, MD, PhD.
Managing small pupils: A step-wise approachBoris Malyugin, MD, PhD, explains how he uses a step-wise approach to manage small pupils, starting with an intracameral injection of phenylephrine or epinephrine and eventually working up to pupil expanders.
