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.

"This fourth edition book serves as a guide to the history of contact lenses, ocular surface anatomy, types of contact lenses, replacement modalities, specialty lenses, and appropriate patient examination and management considerations. Divided into six parts, it begins with basic information on the history of contact lenses with further chapters outlining advanced materials and complex fitting considerations. The book outlines major advances in lens materials, designs, and complications since the first edition. It reviews current clinical diagnostic instrumentation, including corneal topography, ocular biometry, and optical coherence tomography. Full color images, illustrations, and tables enhance the text. The book is an essential guide for contact lens examinations, fitting, material selection, and resolving complications." ©Doody’s Review Service, 2023, Cheryl E Mengelt, OD (Southern College of Optometry)
