Vitreoretinal Surgical Instrumentation
摘要
One year after Machemer et al. reported in 1971 that the vitreous could be removed through a pars plana incision, Conor O’Malley and Ralph Hein introduced the 3-port vitrectomy with a 20-gauge (G) system. Since this humble but important beginning, technological development has led to numerous advances, such as smaller incisions, faster cutter speeds, and advanced illumination systems and visualization methods.
