title: [Prospective study of the incidence of secondary cataract with various types of lenses with and without laser ridge].
abstract: In this randomized, prospective clinical study, a plano-convex (plano-posterior) intraocular lens (IOL) with a laser ridge was compared with a plano-convex (plano-posterior) IOL without a laser ridge. The 100 patients (40 male/60 female) with senescent cataracts all underwent ECCE performed by the same surgeon from November 1986 to March 1987. The operative technique consisted of capsulorhexis, irrigation-aspiration and in-the-bag implantation. The first group of 50 patients (50 eyes) received a sort of IOL without a laser ridge and the second group, a sort with a laser ridge. Our prospective 5-year clinical study is not yet complete and no statistical analysis has been performed. As an intermediate result, however, we have found a rate of 11.7% for after-cateract in the group with an IOL without laser ridge and a rate of 28.6% in the group with an IOL with laser ridge.
