PURPOSE: To describe management of posteriorly retained iris expansion ring-a newly reported complication of phacoemulsification surgery in a patient with intact posterior capsule. METHODS: Case report. PATIENTS: A 64-year-old monocular patient with history of regressed proliferative diabetic retinopathy after pars plana vitrectomy, long-standing glaucoma, and cataract, undergoing phacoemulsification for cataract removal, complicated by posterior migration of the Malyugin ring through area of zonular dehiscence despite intact posterior capsule, which resulted in significant visual disturbance. RESULTS: The intravitreal Malyugin ring was successfully removed by performing a standard 3-port 25-gauge vitrectomy and retrieving the mobilized ring into the barrel of the original injector device. CONCLUSION: A posteriorly retained iris expansion ring can be effectively extracted from the vitreous cavity with the original injector device, which allows for maximal control of the ring and minimal associated surgical trauma.
