The authors of this book are busy practical men with no particular barrow to push. The text of the book includes a comprehensive review of all aspects of intraocular lens surgery including details of the design, optics chem­ istry and sterilization of intraocular lenses. Its value is enhanced by excellent illustrations and extensive tabulated references to the litera­ ture. Accounts of patient acceptability are balanced against candid discus­ sion of complications and their management. The historical introduction recalls that in the early stages of develop­ ment of the art, over a period of 10 years, two dozen different lens designs were proposed, most claiming elimination of problems which had arisen with their predecessors. Eventually nearly all disappeared from the scene. In an age where every cataract surgeon has to determine a personal position on intraocular lens implantation the author's reflections on these matters are timely. Intraocular lenses are neither a miracle nor a menace, provided that personal decisions and preferences are carefully thought through and put into practice upon the basis of known facts and not upon the basis of fickle fashion and fad. This book provides a background upon which the reader can eva­ luate in his own mind the validity of information provided by the manufacturers of various lens designs.
