The author demonstrates on a group of 27 eyes a possible definite solution of a serious complication of successful operation of cataract, i.e. secondary cataract. The latter reduces due to its frequent incidence markedly the visual acuity. The approach with a vitrectome via the pars plana is a simple and permanent solution which beyond doubt has advantages as compared with YAG capsulotomy and polishing of the posterior capsule. Themethodis effective, cheapandthe incidence of complications is minimal. Fluoroangiographic findings confirm its safety.
