Retinoscopy 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

Are you looking for an all-inclusive, comprehensive resource on clinical optics? Look no further than the Clinical Optics Primer for Ophthalmic Medical Personnel: A Guide to Laws, Formulae, Calculations, and Clinical Applications, a new text that presents complex clinical optics in a simple and easy-to-read manner. As ophthalmic medical personnel struggle today between multiple resources for clinical optics, this text offers a solution as it provides everything you need to know - all in one place. Aaron V. Shukla, PhD, COMT has designed Clinical Optics Primer for Ophthalmic Medical Personnel to include everyday examples that may be directly applied to clinical work. Each chapter throughout the text explains one optics concept in a concise account and includes applicable illustrations, formulae, laws, calculations, and review questions. Numerous examples of clinical applications are also included that address problems presented by patients in eye clinics. Some important laws of optics and their clinical applications covered: - Lasers, polarization interference, and fluorescence - Snell's law - Total internal reflection Some important formulae in optics and their clinical applications covered: - Vergence equation - Power of prisms - Optical system of the eye - Accommodation and age - Refractive errors - Prentice's Rule, decentration and induced prism - Glasses and contact lenses With the most up-to-date information for clinical optics, and two chapters solely devoted to the metric system and basic optical mathematics, Clinical Optics Primer for Ophthalmic Medical Personnel: A Guide to Laws, Formulae, Calculations, and Clinical Applications is essential for all ophthalmic assistants, technicians, and technologists, as well as optometrists and ophthalmology residents.
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.
