This book is a complete resource on the purpose, operation, and technical description of all ophthalmic instruments. This second edition updates the first edition that appeared in 1982 and includes the latest instrumentation. Chapters are well organized by instrument type and purpose into a compact and usable text. The foreword of the text, written by Dr. Michel Millodot of Hong Kong Polytechnic, reveals a key feature of the book in that it is probably the only source available for technical information about many of the profession's newer instruments. The author has clearly provided an up-to-date reference for this valuable information. The book is directed at the optometric student or practitioner who will find the text helpful and informative to learn about new instruments and also to refresh their understanding of their clinical favorites. The book will have special value to the vision science researcher who may require specific information on the optical and technical principles by which these instruments function. Dr. Henson's expertise in the technical aspects of ophthalmic instruments comes through clearly in all areas of the text. This book contains many excellent diagrams and photos. The references presented with each chapter are current and pertinent. The book has an excellent index and table of contents, and has an overall quality look and feel. The author writes in a clear and understandable style, even when covering complex technical information. Of special note are the excellent optical and ray-tracing diagrams that accompany the chapters. The autorefraction and retinoscopy chapters are especially informative. This excellent reference and resource book has a place in thelibrary of the clinician. It is of special value to researchers and institutional libraries as a reference text. The second edition has much updated and current information, which makes it an important replacement of the first edition.
Of service either as a resource for the practicing optometrist or as a textbook on instrumentation for the optometry student, this volume provides an authoritative review of the latest instrumentation used in optometric practice for both the measurement of refractive errors and the detection of abnormal ocular conditions. It describes the basic operating principles of the currently manufactured instruments and results from published clinical trials to provide a sense of the accuracy and reliability of each instrument.
