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.
Written to help trainee ophthalmologists, this textbook is now the recognised text on optics for the examinations of the Royal College of Ophthalmologists and the Royal Surgical Colleges. It approaches the subject from first principles and assumes no previous knowledge of optics. The book has been kept as simple as possible and is liberally complemented with diagrams designed to be easily understood and memorised. Only the most fundamental and clinically useful mathematical formulae are quoted, and the optical principles are applied to clinical situations. Ophthalmology examinations have changed substantially since the last edition was written and a total rewrite of this essential guide has become necessary. The third edition has been made more comprehensive and detailed to keep up with these changes and incorporates three new chapters: refractive surgery, contact lenses and lasers. Other new material includes photometry, visual acuity, contrast sensitivity, colour vision, absorptive lenses, fluorescence, ultrasound, and the specular microscope.
It provides a comprehensive and clinically based guide to visual optics. With its suggested routines and numerous examples, this new book offers a straightforward "how to approach" to the understanding of clinical optics, refraction and contact lens optics. Designed for easy access, it presents information in a concise format that highlights key, need-to-know points. Part 1 addresses the basic visual optics of the eye along with emmetropia, ametropia and the correction of ametropia with spectacle lenses. Part 2 turns to the optics of contact lenses and the use of contact lenses in vision correction. Numerous worked examples based on real examination questions Practical and user friendly text Over 190 clear line diagrams An essential passport to examination success and a valuable quick reference for practitioners
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.
A basic optics textbook that integrates relevant visual and ophthalmic optics material with basic geometric and physical optics. Dr. Keating's book uses the vergence approach to optics as well as the wavefront approach to vergence as an aid to developing optics intuition.
Errors of refraction are the most common ocular disorders for which people seek ophthalmic consultancy. Manual of Optics and Refraction is a comprehensive guide to the optics of the human eye and various errors of refraction, including their clinical presentation and management. Divided into eleven chapters, the text extensively covers the physical properties of light, its modification as laser and fibre optic devices, various types of optical devices, their optics, errors of refraction and their clinical presentation and management. Manual of Optics and Refraction provides a comprehensive and clinically based guide to visual optics. The text offers a straightforward approach to the understanding of clinical optics, refraction and contact lens optics, making it useful to trainees, postgraduates and medical teachers, as well as practicing optometrists. Key Points The complex concepts of optics are given easy-to-understand explanations, enhanced by simple illustrations Over 300 full colour and black and white illustrations, images and tables Covers scientific principles, optical devices and refractive surgeries
Optics is the study of the behaviour and properties of light. A refraction test is given as part of a routine eye examination. The test tells an optometrist what prescription is needed in glasses or contact lenses. The new edition of this book is a comprehensive guide to the optics of the human eye and various errors of refraction, including their clinical presentation and management. Divided into eleven chapters, the text extensively covers the physical properties of light, reflection and refraction, curved optical devices, optics of the normal eye and errors of refraction, devices for optical examination, contact lenses, low vision aids, and refractive surgery. The second edition has been fully revised and updated to provide clinicians and trainees with a thorough understanding of the latest advances and technologies in the field. Key Points Practical guide to optics of the human eye and management of refractive errors Fully revised, second edition providing latest advances in the field Highly illustrated with clinical photographs and artworks Previous edition (9789351524502) published in 2014
