Theory and Practice of Optics and Refraction, in its fifth edition, continues to be a part of Modern System of Ophthalmology (MSO) Series. Without altering the basic text and layout, each chapter has been thoroughly revised to keep abreast with the newer concepts and principles of optics and refraction involved in investigative as well as therapeutic optical modalities evolved over the period of time. - Provides information on basic principles of Optics, Refraction and Optical Instruments to Ophthalmology residents and students of Optometry as well as Orthoptics - Text is organized in an attractive four-colour format to make the understanding, retention and reproducibility of facts easy - Includes newer concepts in Refractive Surgery like Topoguided LASIK, Contoura Vision Technology, All Femtosecond Laser Surgery, ReLEx and Corneal Inlay for Presbyopia including Presbyopic Allogenic Refractive Lenticule (PEARL) - Recently available Phakic and near vision enabling Intra Ocular Lenses have been added - Future Refractive Surgeries such as LIRIC, RELIMP and LIKE have been added - Incorporates advances in Aberrometry, Wavefront Technology, Anterior Segment Optical Coherence Tomography (AS-OCT), Enhanced Depth OCT, Confocal Microscopy of Cornea and anterior segment Ultrasound Bio Microscopy (UBM) - Digital Eye Strain and Role of Smartphones in Ophthalmology have been discussed in detail - Chapter on Clinical Refraction has been refurbished effectively and text on Corneal Topography expanded with essential newer developments

Authoritative introduction covers the role of Green's function in mathematical physics, essential differences between spatial and time filters, fundamental relations of paraxial optics, and effects of aberration terms on image formation. "An excellent book; well-organized, and well-written." — Journal of the Optical Society of America. 80 illustrations. 1963 edition.

Written to help trainee ophthalmologists, this textbook is now the recognised text on optics for the examinations of the Royal College of Ophthalmologists and the Royal Surgical Colleges. It approaches the subject from first principles and assumes no previous knowledge of optics. The book has been kept as simple as possible and is liberally complemented with diagrams designed to be easily understood and memorised. Only the most fundamental and clinically useful mathematical formulae are quoted, and the optical principles are applied to clinical situations. Ophthalmology examinations have changed substantially since the last edition was written and a total rewrite of this essential guide has become necessary. The third edition has been made more comprehensive and detailed to keep up with these changes and incorporates three new chapters: refractive surgery, contact lenses and lasers. Other new material includes photometry, visual acuity, contrast sensitivity, colour vision, absorptive lenses, fluorescence, ultrasound, and the specular microscope.
