Request a sales quoteTheory 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
