Clinical Refraction And Visual Science

Completely updated, revised, and redesigned, this edition includes all of the features that have made it so successful in the past, such as succinct understandable definitions, extensive tables and illustrations, and practical clinical advice. Plus, it now includes many new entries on pathology, pharmacology, investigative techniques, refractive surgery, contact lenses and visual perception. Over 5400 terms are included. Tables and helpful illustrations help users understand important concepts and terms. Foundation information is offered on essential areas such as basic sciences, optics, and refraction. Practical clinical advice included with many definitions. New entries covering ocular pathology, ocular pharmacology and therapeutics; ocular anatomy and basic sciences; investigative techniques; psychology of vision; and visual perception. Thoroughly updated to include the latest information on topics relevant to the optometric profession. New tables and illustrations highlight and clarify key concepts.

Now updated and expanded to cover the latest technologies, this full-color text on clinical refraction uses an easy-to-read format to give optometry students and practitioners all the important information they need. Also covers a wide range of other aspects of the eye exam, including anterior and posterior segment evaluations, contact lens, ocular pharmacology, and visual field analysis. Four new chapters cover wavefront-guided refraction, optical correction with refractive surgeries, prosthetic devices, and patients with ocular pathology. Offer precise, step-by-step how-to's for performing all of the most effective refractive techniques. Presents individualized refractive approaches for the full range of patients, including special patient populations. Contriubtors are internationally recognized, leading authorities in the field. New full-color design with full-color images throughout. Completely updated and expanded to include current technologies. A new chapter on Optical Correction with Refractive Surgeries, including keratoplasty, traditional refractive surgeries (e.g. LASIK and PRK), crystalline lens extraction with and without pseudophakia, the new presbyopic surgery, etc. A new chapter on Wavefront Guided Refraction provides information on the advantages and limitations the Hartmann-Shack Method for objective refraction plus aberrometry and the refraction and the use of in the correction of the eye with spectacles, contact lenses, and refractive surgery. A new chapter on Patients with Ocular Pathology reflects the most current knowledge of patients with ocular pathologies. Provides information on Optical Correction with Prosthetic Devices, including corneal onlays, stromal implants, phakic intraocular lenses, etc. Includes new chapters and/or discussions on such topics as: Aberrations of the Eye, Refractive Consequences of Eye Pathology, Diagnosis and Treatment of Dry Eye, Diagnosis of Pathology of the Anterior Segment, Diagnosis of Glaucoma, and Diagnosis of Pathology of the Posterior Segment. Visual Acuity chapter expanded to include the effect of refractive error on visual acuity and statistics on how much of a change in visual acuity is significant. Objective Refraction, Corneal Topography, and Visual Field Analysis chapters include the addition of new electro-optical and computer techniques and equipment. Chapters on Multifocal Spectacle Lenses and Contact Lenses now cover newer progressive addition lenses and contact lenses that are now on the market. Electrodiagnosis chapter revised to take a more clinical approach.

- This book covers all the major aspects of practical ophthalmic examinations along with clinical optics and optometry - Provides a comprehensive knowledge on basic anatomy and physiology of the normal human eye and its optical principles guide on the different types of refractive errors/defects and their correction in a most lucid and methodical manner - It succinctly elaborates on the fundamentals of optics and refraction of the eye in an innovative fashion - It emphasizes on the utility of various optical lenses, frames, measurements and contact lenses - This book will assist and guide to make quick, accurate and clinically appropriate decisions.

Clinical Optics is intended primarily for use by optometry students, though it could also prove useful for the training of optometric technicians and dispensing opticians. This book is organized into thirteen chapters. These chapters cover most aspects of ophthalmic optics or clinical optics including the design and dispensing of eyewear, the types for lenses suitable for correcting high refractive errors, the optical principles governing low vision lenses and the importance of absorptive lenses and lens coatings for eye protection against radiation. This book will be of interest to optometry students and to those involved in the training of optometric technicians and dispensing opticians.

The only text for optometric optics courses! This concise, reader-frie ndly, highly visual text covers key topics in geometrical and visual o ptics foundational in all optometry programs and the practice of optom etry. The book provides a valuable study for the NBED licensing examin ation in optometry. Featuring over 300 illustrations, this textbook co ntains numerous examples and problems, including self-assessment quest ions at the ends of chapters, with solutions in the back of the book.
