Dr. Snyder has, with Dr. Robert Osher, pioneered artificial iris prosthesis use in the United States, aiding in the rehabilitation of acquired traumatic iris defects or congenital iris defects such as aniridia and ocular albinism. He organized and executed the clinical study that led to the first and only FDA approval of the custom-matched artificial iris. Dr. Snyder has also been a clinical investigator in numerous trials of new presbyopia-correcting intraocular implant lenses and implantable sustained release pharmaceutical agents.
