The Barraquer experience with intraocular lenses. 20 years later.

The Barraquer Clinic experience in lens implantation is briefly reviewed. About 500 lenses were implanted in a seven-year period, with excellent early results. Late disasters, particularly corneal dystrophy, required the removal of over 300 of these lenses. Recently an extensive analysis has been completed of 162 of the lenses removed. These included Ridley, Strampelli, Dannheim, Boberg-Ans, and Barraquer lenses. The examination of the lenses themselves, coupled with current knowledge of design requisites for intraocular lenses, permits a scientific analysis of these early implants and the problems associated with their use.
