DOWNLOAD EBOOKIt 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

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.

DOWNLOAD EBOOKClinical 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.

DOWNLOAD EBOOKRetinoscopy is an eye exam that determines the refractive error of the eye (long sighted, short sighted, astigmatism). A refraction test indicates the strength of the prescription needed for glasses or contact lenses. The new edition of this book provides a concise overview of clinical refraction. Presented in an easy to read format, it is divided into two main sections. The first part explains basic clinical procedures for routine refraction, beginning with an introduction to instruments and the procedure, followed by aspects of the test for different disorders including myopia (short sightedness), astigmatism, keratoconus and refraction in children. Section two provides in depth discussion on retinoscopy and correct use of the retinoscope. The second edition has been fully revised and updated to explain the latest advances in the field, and is further enhanced by clinical images and figures. Key points Practical guide to clinical refraction and retinoscopy Fully revised and updated second edition Explains basic procedures and instruments for refraction test and refraction in different ophthalmic disorders Previous edition (9789351520634) published in 2014

DOWNLOAD EBOOKThe material in this edition of A d104book of Clinical Ophthalmology has been thoroughly revised and expanded to include the latest research and practice. Containing 357 illustrations throughout the text, the book is not only a reasoned practical guide to the study of ophthalmology, but it embraces the ocular aspects of general diseases world-wide and basic methods of investigation and treatment where applicable.This book has references by page and illustration number, resulting from collaboration with the authors of Colour Atlas of Ophthalmology; the two books contain all together an outstanding 579 illustrations (343 in colour), including 16 stereo plates. Another companion book is The Ophthalmology Examinations Review, which aims at the most effective presentation of knowledge for examination purposes. Together these three compact and inexpensive books provide an excellent study basis for ophthalmologists in training, while supplementing their learning of clinical work and surgical technique with the essential study of recent research papers and review monographs.

DOWNLOAD EBOOKWritten 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.
