Available in PDF, EPUB and Kindle. Book excerpt: Cataract surgery, with 25-30 million surgeries per year, has become one of most popular surgeries in the world. The calculation of its power is of utmost importance. As new premium intraocular lenses (IOLs) and modern surgical techniques have been developed, the demand has grown exponentially - not only for eliminating cataracts, but also for getting rid of the need for glasses. This book offers a comprehensive overview of IOL power calculations and its various formulas and methods. Chapters discuss use of the diagnostic biometry devices that provide the measurements and the management of different clinical situations where particular modifications must be applied. Chapters also discuss the newest generation of multifocal and toric IOLs that can only be implanted if no residual refraction is planned for, which implies a perfect mastery of all the IOL calculation process. This book marks the first time in ophthalmological history that all the main leaders inthe field have collaborated in a project that will undoubtedly be the reference for the next ten years. Intraocular Lens Calculations is a must-have resource for cataract and refractive surgeons as well as technicians and anyone dealing with this subject.

Edited by a renowned master surgeon and educator in the field, and authored by a remarkable cast of cataract experts, this is the definitive text on managing cataract surgery, with practical guidance on recognizing and managing complications, should they arise. Experts demonstrate the right way to perform phacoemulsification and diverse surgical and intraocular lens implantation procedures in order to reduce risk and improve patient outcome. This second edition is greatly expanded in size and scope to accommodate the latest state-of-the-art methodologies and refinements in surgical strategies. Since the first edition was published, new techniques for refractive cataract surgery, vitrectomy, IOL exchange, and management of IOL implantation without capsular bag support have been improved. Additionally, new technologies have been introduced such as optical coherence tomography, FLACS (femtosecond laser surgery), and implantation of toric and multifocal refractive IOLs, as well as methods to improve IOL power calculation and decision making. Highlights A stellar group of national and internationally renowned eye surgeons provide invaluable clinical pearls gleaned from years of refining procedures Surgical videos further elucidate the most optimal surgical strategies More than 600 superb illustrations Management of challenges including small pupils, IFIS, zonular weakness, inadequate capsular support, vitrectomy, corneal burns, high astigmatism, dysphotopsias, and endophthalmitis This invaluable reference will help ophthalmologists refine their expertise, resulting in fewer risks and more efficacious outcomes.
