This volume constitutes the Proceedings of the Fifth Contact Lens Seminar which was held at Ohio State University College of Medicine, Columbus, Ohio, in September 1970. Most of the national authorities on contact lenses, some theoretical academicians, and quite a few representatives from industry were on hand to compare notes on the rapidly expanding field of both soft and hard contact lenses. The Bausch and Lomb soft lens, the Griffin lens (Bionite Naturalens), the Muller-Welt silicone lens, and the Seiderman lens were separately described, and the clinical results in ametropias and corneal disease were discussed. Most investigators found the hydrophilic soft lens to be exceptionally well tolerated, but visual acuity was, as a whole, inferior to that achieved with the conventional hard lens. The medical usefulness in various types of corneal pathologic findings is considerable.
Hill, as well as Hoefle and Koverman, contributed two excellent articles on the oxygen permeability
