Book Description
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

Book Description
The first clinical application of intraocular lens (IOL) goes back to 1949 when Dr. Harold Ridley successfully implanted a PMMA IOL into an eye on 29 November 1949. This innovation is a big step forward for cataract surgery. With development of the IOL material and biocompatibility, more and more IOL types have been used in clinical ophthalmology. This book is the fruit of worldwide cooperation between clinical teams. In this book we discuss the IOL materials and design, aberration and astigmatism correction with IOL, entopic phenomenon of IOL, myopia and phakic IOL, and secondary IOL techniques. We believe that this content provides the readers with a comprehensive knowledge of the latest developments of IOL.

Book Description
Renowned master surgeons share best practices for effectively performing cataract surgery and avoiding complications Phacoemulsification, the gold standard for cataract extraction, is highly successful. However, the procedure is not without risks and complications. Poor visual outcome, retinal detachment, infection, diplopia, and cornea and iris problems may pose considerable challenges. Additional potential problems arise from implanting the intraocular lens (IOL). 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. It is a must-have resource for ophthalmology residents and proficient surgeons alike.
