title: Posterior chamber intraocular lens implantation: further review of the Severin lens.
abstract: A consecutive series of 116 Severin lens implantations with a mean follow-up time of 9 months was reported 2 years ago. In view of the excellent early outcome the series was continued and the results of the initial series is further reviewed at a mean follow-up time of 28 months. The entire series of 305 Severin lens implantations with a mean follow-up time of 21 months is reported. The early results are compared with the longer term results. Intraocular lens implantation in the United Kingdom is equally divided between extracapsular extractions with a posterior chamber lens and intracapsular extractions with an iris fixated lens, anterior chamber lenses taking third place. While the advantages of the extracapsular technique are undisputed, until YAG Lasers are more widely available for dealing with thickened posterior capsules, an intracapsular technique with an iris fixated lens may still have a place.
