Montague Ruben has edited and contributed to an in-depth and detailed collection of essays on the various aspects of the technology related to soft contact lenses. The book is divided into sections, the first of which deals with the historical background. It is of interest to note where all this work began and to see how much has developed in roughly two decades.
There follow seven chapters that deal with the physicochemical properties of the soft materials. Oxygen permeability, metabolic changes induced by the covering of a cornea, temperature alterations, and optical qualities are thoroughly and technically presented. Next the techniques of fitting are presented. Both the spuncast and lathe-cut lenses are discussed. Residual astigmatism problems, continuous-wear lenses and the difficulties associated with them, and the therapeutic uses of soft lenses in anterior membrane diseases and keratoconus are well presented. Chapters are included concerning soft lenses as drug delivery systems
