• Pars plana surgery was performed, using a vitreous infusion suction cutter, for the treatment of after-cataracts, traumatic pupillary membranes, inflammatory pupillary membranes, and various pupillary membranes combined with other posterior segment problems. Surgical complications were minimal. A permanent pupillary opening was achieved in all but one case. Visual success was dependent on the underlying disease. One should not operate during active phases of uveitis.
