title: Four and one-half year study of the relationship between one-piece encircling loop polymethylmethacrylate lenses and retinal detachment.
abstract: Prospective studies in this series of 2,802 patients have shown that the incidence of retinal detachment is significantly reduced with an intact posterior capsule. Furthermore, if a capsulotomy has to be performed, the data from this series suggest that it is preferable not to open the capsule at the time of surgery but at a later time, when the IOL optic has fixed to the posterior capsule. A subsequent YAG capsulotomy will not disrupt this apposition and will not alter the barrier protection of aqueous movement to the vitreous. This effect can be achieved with a continuous ridge on the posterior surface of the lens or, alternatively, with a convex posterior IOL surface.
