Six hundred and eighty five eyes with pseudophakia after implantation of anterior chamber (162), posterior chamber (29) and pupillary lenses (494) were subjected to an analysis. Intraocular hypertension after implantation was observed sometimes either as a transitory or a permanent one. The frequency of glaucoma in eyes with pseudophakia is dependent on the kind of the implant. In the material investigated the chronic glaucoma was found relatively most frequently after implantation of anterior chamber lenses, less frequently after implantation after pupillary implantation, the least frequently after posterior chamber implantations. In cases of an ineffective pharmacological treatment trabeculectomy was performed.
