Download Intraocular Lens Power Calculations Book in PDF, ePub and Kindle
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

IOL Power by Kenneth J. Hoffer, MD will be the definitive resource worldwide for ophthalmologists who strive to increase the accuracy for all IOL calculations,especially for multifocal IOLs and overcoming the challenges that arise when treating patients that have had laser refractive surgery, such as RK, PRK, LASIK, and LASEK. Inside the pages of IOL Power, Dr. Hoffer is joined by some of the most respected international physicians and physicists in the field of IOL power such as Aramberri, Haigis, Norrby, Olsen and Shammas. Together their expertise, spanning over 35 years, makes even the most difficult subjects easy to understand. This volume will become the definitive reference source on the subject of IOL power calculation. Some topics include: Ultrasound velocities for axial length measurement Optical AL (IOLMaster and Lenstar) in difficult eyes Manual and automatic keratometry and instrumentation Topography & Scheimpflug camera corneal power Value of theoretic formulas Formula personalization Multifocal and toric IOLs Aspheric IOLs Effect of IOL tilt on astigmatism Chapters Cover: All aspects of obtaining the most accurate biometry Available modern calculation formulas Latest instruments Problems that can arise, how to prevent and repair them IOL Power by Kenneth J. Hoffer, MD is structured in a logical manner so as to cover every facet of IOL power from the basics to the most complicated subjects to achieve the most accurate and precise calculations and should be in the hands of all ophthalmic surgeons, technicians, residents and students.

Download Lens Surgery after Previous Refractive Surgery Book in PDF, ePub and Kindle
This book addresses an increasing need that is confronting ophthalmologists all over the world today, and that is the growing number of previous refractive surgery patients. A unique contribution by internationally recognized leaders to address all aspects of lens-based surgery on previous refractive patients, including issues surrounding when to intervene, biometry, considerations for the surgical procedure itself, lens choices, management of complications, and views into the future. The text represents an excellent opportunity for ophthalmologists to experience increased satisfaction from their practices, improve the financial health of their practices, and feel the gratitude of patients for the enhanced quality of their lives. Presents the problem in a comprehensive way so that the ophthalmic surgeon in private practice would find answers to the common questions like: When is the right time to replace the lens in an eye that had refractive lens surgery before hand? How do we do it? What are the pitfalls? How to avoid complications? How do we perform correct IOL power calculation in eyes developing cataract after earlier refractive corneal surgery? And finally outcomes of different approaches and future developments have been discussed. Also includes a chapter by Kezirian and Waring on the opposite topic; laser surgery after intraocular implants and answer the questions by bringing together the expertise of Internationally well-known specialists in the field. Contains the knowledge of the physicists—of the pioneers who developed the first formulas—and of the surgeons in daily practice who are handling over the practical tools in the section of IOL Power Calculation. In the section of Decision Making, top surgeons gave their advice and personal approach. In the section of The Surgery, experienced surgeons gave some pearls when starting surgery in eyes that had refractive surgery earlier. This book useful for ophthalmologists, ophthalmic surgeons, refractive surgeons.

Publisher's Note: Products purchased from Third Party sellers are not guaranteed by the publisher for quality, authenticity, or access to any online entitlements included with the product. 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.

Download Astigmatism Book in PDF, ePub and Kindle
This book explores the development, optics and physiology of astigmatism and places this knowledge in the context of modern management of this aspect of refractive error. It is written by, and aimed at, the astigmatism practitioner to assist in understanding astigmatism and its amelioration by optical and surgical techniques. It also addresses the integration of astigmatism management into the surgical approach to cataract and corneal disease including corneal transplantation.
