Presents all aspects of IOL power calculations by international masters of the field. In the past, patients quietly accepted needing an eyeglass prescription after cataract surgery. That is no longer true. This textbook explains just why a more complex evaluation of the eye is needed, and will describe the state of the art in the technology used to ensure the best possible results today. IOL power calculation is a complex and important subject. A number of new formulas have come up for cataract and refractive surgeons which deliver good outcomes and provide another avenue to validate IOL selections. This international book of IOL power calculations covers all aspects of calculations from normal cornea to after refractive surgery, in Phaco/Microphaco, on irregular corneal surgace, in phakic IOLs, in corneal scarring and astigmatism, and in pediatric cataract surgery.

- This international book covers all aspects of calculations from normal cornea to after refractive surgery in phaco/microphaco, on irregular corneal surface, in phakic IOLs, in corneal scarring and astigmatism - New technologies have been introduced - An update and comprehensive standard international book.

The selection of appropriate formulas and surgical techniques is vitally important to best fulfill each patient's visual needs and expectations. With over 30 years of experience, H. John Shammas, MD clearly explains the importance of intraocular lens (IOL) power calculations during preoperative cataract evaluation and their role in positively improving surgical outcomes. Intraocular Lens Power Calculations addresses both currently used and the latest, more advanced formulas. To fully understand the application of these formulas in various situations, thorough explanations are provided. Numerous highlighted clinical applications, case reports, figures, and tables are also utilized to illustrate and reinforce key points. This well-organized text contains the most up-to-date information on axial length measurement, biometry units, constants, and ways to avoid errors. IOL power calculations and selection are included for an array of conditions ranging from the normal phakic eye to the more challenging high myopic and high hyperopic eyes, piggyback implantation, intumescent cataract, and the aphakic eye. Intraocular Lens Power Calculations updates surgeons, technicians, and students on all the techniques and formulas available to achieve the most accurate and precise calculations, thus paving the way for surgical results that fulfill patients' visual needs. Topics Include: New formulas including Holladay, Olsen, and Haigis IOL power calculations after corneal refractive surgery Calculating for emmetropia and iseikonia High precision A-scan biometry B-mode guided biometry Optical coherence biometry Selecting the proper IOL power

The IOL technical specifications, the clinical data, and the necessary clinical and surgical skills comprise the scientific foundation for achieving a "premium" refractive outcome. To consistently achieve patient satisfaction, however, requires mastering the art of patient and IOL selection, communicating and counseling effectively, and providing a "premium" patient experience. This is a nontraditional book in which multiple experts are separately asked to discuss controversial subjects in a reader-friendly format. There is balanced coverage of all of the available refractive IOLs, as well as those that may become available in the near future. A major emphasis is placed on avoiding and managing complications or potentially dissatisfied patients. There are more than 200 chapters that are organized into 14 major sections, over 300 images, 100 tables, and 12 sidebars that cover every aspect of refractive IOL clinical practice. This is a comprehensive educational resource addressing the most demanding and rapidly evolving area in cataract and refractive surgery today and the first book to cover both the clinical and nonclinical aspects of offering refractive IOL services.

New edition presenting latest developments in ophthalmic diagnostic procedures. Fully revised and many new chapters. Previous edition published in 2009.

Part of the new series Gems of Ophthalmology, this book provides ophthalmic surgeons with the latest advances in cataract surgery. Divided into 24 chapters, the book begins with an overview of incision making, followed by discussion on different types of lenses. The next sections cover a variety of techniques in cataract surgery including phacoemulsification for patients with other existing ocular conditions such as uveitis, corneal diseases and those that have previously undergone vitrectomy procedures. The book concludes with discussion on femtosecond laser-assisted surgery. Complete chapters are dedicated to paediatric cataract surgery and toxic anterior segment syndrome (acute inflammation following generally uneventful cataract and anterior segment surgery). This comprehensive text is further enhanced by clinical and surgical photographs, diagrams and tables. Other topics in the series include: Cornea & Sclera, Diseases of the Uvea, Glaucoma, and Retina. Key points Comprehensive guide to latest advances in cataract surgery Part of the new Gems of Ophthalmology series Covers many basic and more complex procedures Other topics in the series include: Cornea & Sclera, Diseases of the Uvea, Glaucoma, and Retina

Cataracts are a very common condition and over time can lead to blindness if untreated. They are the most common cause of blindness worldwide. Cataract surgery is one of the most commonly performed procedures. Cataract Surgery in Diseased Eyes presents different surgical techniques to remove cataracts in patients with other pre-existing ocular disorders. Presented as case scenarios, the book covers numerous different conditions including dry eye, uveitis and glaucoma, as well as cataract surgery after other types of eye surgery. With contributions from internationally recognised specialists in Europe, North America and Asia, this useful guide includes more than 200 images, illustrations and tables to enhance learning. Key points Describes cataract surgery techniques for use with other pre-existing eye conditions Presents more than 30 case scenarios covering different disorders Contributions from experts in Europe, North America and Asia Includes more than 200 images, illustrations and tables
