Optics, Retinoscopy, and Refractometry, Second Edition is a valuable and up-to-date reference that allows the reader to better understand and measure the patient's refractive error. Information is presented on each of the three important topics in an easy-to-read format. Al Lens, COMT begins Optics, Retinoscopy, and Refractometry with a focus on the basics of optics, providing the foundation for understanding retinoscopy. The detailed instructions and practical exercises help the beginning technician become proficient at the valuable skill of retinoscopy. This comprehensive resource concludes with a simplified approach to refractometry, including a section on refractive surgery from an optics perspective. New to this edition: A section on refractive surgery from an optical point of view. Discussion on wavefront technology. Updated text and diagrams. Features: Study icons throughout the text. Appendices containing data on the metric system, units of measurement, metric conversions, and abbreviations. Refractometry exercises. Whether you are a beginning technician looking for a basic overview or an experienced examiner in search of a clear-cut review, Optics, Retinoscopy, and Refractometry, Second Edition will suit all your optics needs.

No systematic analysis of optometric clinical data can be undertaken unless the findings are referred to a logical model that allows comparisons to be made of interaction characteristics that exist between the accommodative and convergence mechanisms inherent to the human vision system. Concomitantly, many of the concepts applied during any such analytical process are based on hypothetical constructs. This text re-examines the elements originally proposed by Dr. A.M. Skeffington, and offers a revised insight into how performance changes may occur as individual visual behavior adapts to the impact of environmental demands. In-depth research and extensive references attempt to substantiate the Skeffington paradigm of professional vision analysis. Long-standing challenges to the optometric profession are identified. As presented, the contents are appropriate for use as a classroom text, for reference, and for identifying areas for clinical research.

Time is an incredibly valuable resource for ophthalmic and para-optometric personnel, whether they are still studying on their way to certification or they are already in the trenches in daily practice. To keep up, they need a single, cohesive text containing everything they need to learn. Principles and Practice in Ophthalmic Assisting: A Comprehensive Textbookmeets that need, covering all subject areas in detail while also maintaining a readable, user-friendly style. Editors Janice Ledford and Al Lens have gathered a prestigious team of over 40 contributors, all of them ophthalmic and optometric medical personnel, who actively perform the tasks they write about. Their time-tested expertise is like having a group of specialists right by your side to show how it’s done and answer questions. From A-scan to zygoma, Principles and Practice in Ophthalmic Assisting: A Comprehensive Textbookincludes everything ophthalmic and para-optometric personnel need to know to effectively perform their duties, assist their patients, and advance their careers. Each chapter is written in a friendly manner and follows an established framework, making it easy to digest any new information or as a quick reference to the material needed. Chapters also include valuable “tricks of the trade” that could only come from authors with intimate knowledge of their topics. Topics covered: General ophthalmic knowledge Ophthalmic skills Optical skills Ophthalmic medical sciences Surgical services and skills Administrative skills Whether perfecting current skills, learning new ones, or studying for exams, Principles and Practice in Ophthalmic Assisting: A Comprehensive Textbook makes both a perfect learning tool for students and a complete reference tool for staff whether they are new to the eyecare industry or have years of experience.

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.

The Basic Bookshelf for Eyecare Professionals is a series that provides fundamental and advanced material with a clinical approach to clinicians and students. A special effort was made to include information needed for the certification exams in ophthalmic and optometric assisting, low vision, surgical assisting, opticianry, and contact lens examiners. This handbook is a compilation of information from books in the Basic Bookshelf for Eyecare Professionals. This book serves as an ophthalmic pocket companion for the eyecare paraprofessional, complementary to the entire series. With 100 tables and illustrations throughout the text, the reader will find this an extremely useful guide covering essentially every aspect of patient care. Tables regarding tests, drugs, disorders, motility, first aid, microbiology, and more will have you pulling this book out frequently, even in the exam room. The condensed format makes it ideal for studying as well.
