The surgical correction of astigmatism is the last frontier to optimizing visual outcomes for patients. Practical Astigmatism: Planning and Analysis is a comprehensive guide to correcting astigmatism from pre-operative planning to post-operative analysis. This provides readers with unique insight to what actually happened surgically: did the astigmatism over or under correct? Was it on-axis or off-axis? With this book, ophthalmologists will be able to analyze previous procedures with the appropriate nomograms and more often achieve targeted outcomes. Dr. Noel Alpins has developed the Alpins Method of astigmatism to provide accurate planning and analysis of astigmatism procedures. His method focuses on analyzing refractive and corneal astigmatism parameters and using the results in future surgery to improve visual outcomes. The importance of the ocular residual astigmatism (ORA) is detailed when planning astigmatism surgery. Practical Astigmatism features vector planning for refractive laser surgery as well as planning and analysis applied to cataract and limbal relaxing incisions, , in addition to demonstrating graphical analysis of astigmatism using high quality vector and fan diagrams, as used in scientific journals. In addition, hemidivisional analysis of the irregular cornea, corneal coupling in incisional and excimer laser surgery for mixed astigmatism and toric IOL planning with total corneal power using corneal topographic astigmatism (CorT total) are addressed as well. Some Questions Answered Inside: What is the difference between regular and irregular astigmatism? How do I diagnose each, and how does this affect my surgical technique? Can I incorporate corneal astigmatism when performing excimer laser surgery? Why are my LRIs undercorrecting the astigmatism? Is it safe to perform excimer laser on keratoconous patients? Which corneal astigmatism measure do I choose and what do I do following a refractive surprise? Practical Astigmatism: Planning and Analysis will help ophthalmologists, optometrists, and technicians alike address each patient’s unique circumstances and act as your in-depth guide to correcting astigmatism. Testimonials... “For more than three decades I have been listening to, arguing with, and admiring the work of Dr. Noel Alpins in the field of astigmatism. Despite his remote location on the small island of Australia, his knowledge of astigmatism is at the peak of Mt. Everest. There are few others who have devoted their careers to understanding and managing astigmatism for which the world of ophthalmology is truly grateful.” - Robert H. Osher, MD “Noel is an original thinker who took on and conquered the complexities of astigmatism analysis, publishing the seminal papers on the way. His work has formed the cornerstone from which our current understanding and management of astigmatism has been built. He is someone from whom we have all learnt a great deal and this book is a testament to this.” - Dan Z Reinstein, MD MA(Cantab) FRCSC DABO FRCOphth FEBO

This book explores the development, optics and physiology of astigmatism and places this knowledge in the context of modern management of this aspect of refractive error. It is written by, and aimed at, the astigmatism practitioner to assist in understanding astigmatism and its amelioration by optical and surgical techniques. It also addresses the integration of astigmatism management into the surgical approach to cataract and corneal disease including corneal transplantation.

The cornea is the transparent front part of the eye covering the iris and the pupil, allowing light to enter and covering two thirds of the eye’s focusing tasks. This two volume set is a comprehensive guide to the latest research and techniques for the cornea. Beginning with basic science, examination techniques and epidemiology, the following chapters discuss the diagnosis and the medical and surgical treatment of numerous different conditions and diseases that may affect the cornea. Written by an extensive international editor and author team, this manual features more than 1300 full colour clinical and histopathological images, as well as a DVD demonstrating a multitude of surgical techniques described in the book. Key points Comprehensive two volume set describing diagnosis and treatment of numerous corneal disorders Features more than 1300 colour images and illustrations Includes a DVD demonstrating surgical techniques and procedures Extensive international author and editor team

The field of contact lenses continues to evolve at a rapid pace, with new optical designs and vision correction options continually being developed. Additionally, the rapid expansion of clinical instrumentation offers eye care practitioners a wide choice of investigative techniques for assessing in-eye contact lens performance and diagnosing adverse reactions. Now in its fourth edition, Contact Lens Practice has been thoroughly updated and revised to capture these developments and more, and translate them into an organised and easily digestible resource. Written and edited by award-winning author, researcher, and lecturer, Professor Nathan Efron, this title provides a comprehensive, evidence-based overview of the scientific foundations and clinical applications of contact lens fitting. The text has been refreshed by the inclusion of five new authors – a mixture of scientists and clinicians, all of whom are at the cutting edge of their specialty. - Serves as an essential companion and guide to current thinking and practice in the content lens field, ideal for use by optometrists, ophthalmologists, orthoptists, opticians, students, and contact lens industry professionals. - Presents subject matter in a clear and logical format to allow the reader to quickly identify and comprehend key information. - Features highly illustrated chapters in full colour, helping the reader to visualize core concepts. - Includes completely rewritten chapters, by new authors, on scleral and corneo-scleral contact lenses, high ametropia, therapeutic applications, post-surgical lens fitting, and practice management. - A new chapter on Post-Surgery Management consolidates core information on post-operative management involving contact lenses. - Enhanced eBook version included with purchase. Your enhanced eBook allows you to access all of the text, figures, and references from the book on a variety of devices.

This comprehensive text and reference addresses the full scope of contemporary contact lens science and practice. With two expert editors and 100 first-rate contributors, the book presents practitioners and students in optometry and ophthalmology with key facts on corneal anatomy, recent research, contact lens design, patient evaluation, clinical applications, patient education, and complications of contact lens wear. More than 600 illustrations complement the text. Clinical Contact Lens Practice will be the standard text for required contact lens courses and will be an invaluable everyday reference for practitioners.

The first edition of this book was widely praised as an excellent introduction to electron microscopy for materials scientists, physicists, earth and biological scientists. This completely revised new edition contains expanded coverage of existing topics and much new material. The author presents the subject of electron microscopy in a readable way, open both to those inexperienced in the technique, and also to practising electron microscopists. The coverage has been brought completely up to date, whilst retaining descriptions of early classic techniques. Currently live topics such as computer control of microscopes, energy-filtered imaging, cryo- and environmental microscopy, digital imaging, and high resolution scanning and transmission microscopy are all described. The highly praised case studies of the first edition have been expanded to include some interesting new examples. This indispensable guide to electron microscopy, written by an author with thirty years practical experience, will be invaluable to new and experienced electron microscopists in any area of science and technology.
