Contemporary Scleral Lenses: Theory and Application, provides comprehensive information about scleral lenses. Chapters of this volume have been contributed by renowned scleral lens experts and cover a variety of interesting topics. These topics include the history and evolution of scleral lenses, basic scleral lens structure, optics and customizable features of scleral lenses, analysis of ocular surface shape, ocular surface topography and advances in optometry technology. These topics give readers an explanation of how to utilize diagnostic equipment in optometry practice and enables practitioners to employ a scientific and objective approach to scleral lens fitting. Key features of this volume include: - A straightforward approach to ophthalmic examination flow, evaluation and documentation - A review of Scleral lens care and handling - Descriptions of a variety of complex medical and ocular indications for scleral lenses - Strategic tips to promote your own scleral lens practice - A unique perspective of esteemed corneal specialists regarding the collaborative care of the patient This textbook is a suitable reference for ophthalmology students and practitioners. This text will assist practitioners in enhancing their scleral lens practice by providing them useful information for improving patient vision, ocular surface rehabilitation and quality of life.

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.

Ocular Therapeutics Handbook: A Clinical Manual is directed at the needs of optometrists, nurses and primary care physicians and provides succinct, rapid access information for most common ocular problems encountered in a primary care setting. It is divided into three sections: Quick Reference, Ocular Therapeutics and Appendices. The Quick Reference section covers such topics as ocular microbiology, lab tests and procedures, pharmaceutical agents, and side effects of medications. The Ocular Therapeutics section discusses diseases, traumatic injuries, and ocular urgencies and emergencies. The appendices provide a summary of abbreviations, conversion charts, case report sheets and important phone numbers. The chapters have been developed to serve as a snapshot, presenting the clinician with the most relevant information regarding the pathophysiology and etiology of diseases, patient demographics, signs and symptoms, lab tests, and recommended approaches to treatment.

Designed to be used as a quick reference, this fourth edition of the Clinical Manual of Contact Lenses allows readers to easily find the topic and information they need without having to search through an entire chapter to find it. Rigid gas permeable lens design and fitting, soft lens problem-solving, astigmatic management, and bifocal correction are just a few of the subjects covered in this manual. Each chapter includes sample cases to reinforce and demonstrate the practical nature of the topic, with nomograms and proficiency checklists summarizing and emphasizing the important points. With this guide, students and practitioners will have a dependable resource to help fit, evaluate, and troubleshoot any contact lenses, especially specialty designs for years to come.

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.
