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.

This book summarizes current understanding of the scientific, clinical, and technical issues surrounding the use of contact lenses. It discusses the special occupational conditions experienced by military personnel, particularly in extreme environments, that give rise to the question of whether or not to use contact lenses. Experts in optometry, ophthalmology, visual psychophysics, and engineering describe recent developments in design and use; and representatives of the military services provide examples of actual situations in aerospace settings. Considerations in Contact Lens Use Under Adverse Conditions will be of particular interest to those involved in the design of contact lenses and those responsible for occupational safety and health matters in the private sector.

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.
