Lens Implantation


Book Description

The authors of this book are busy practical men with no particular barrow to push. The text of the book includes a comprehensive review of all aspects of intraocular lens surgery including details of the design, optics chem istry and sterilization of intraocular lenses. Its value is enhanced by excellent illustrations and extensive tabulated references to the litera ture. Accounts of patient acceptability are balanced against candid discus sion of complications and their management. The historical introduction recalls that in the early stages of develop ment of the art, over a period of 10 years, two dozen different lens designs were proposed, most claiming elimination of problems which had arisen with their predecessors. Eventually nearly all disappeared from the scene. In an age where every cataract surgeon has to determine a personal position on intraocular lens implantation the author's reflections on these matters are timely. Intraocular lenses are neither a miracle nor a menace, provided that personal decisions and preferences are carefully thought through and put into practice upon the basis of known facts and not upon the basis of fickle fashion and fad. This book provides a background upon which the reader can eva luate in his own mind the validity of information provided by the manufacturers of various lens designs.




Phacoemulsification and Intraocular Lens Implantation


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.







Pediatric Cataract Surgery and IOL Implantation


Book Description

Pediatric Cataract Surgery and IOL Implantation: A Case Based Guide is a must-have resource for ophthalmologists, surgeons, residents, and fellows who work with pediatric cataracts and their surgical management as well as ancillary readers such as parents or supportive caregivers to a child with cataracts. This book offers a comprehensive overview of the epidemiology of pediatric cataract surgery and considerations surrounding IOL implantation. It addresses pre-operative evaluation and examination, as well as surgical steps and techniques for various pediatric cataract conditions. Chapters begin with an introduction and are followed by discussions that offer expert viewpoints and case studies. In addition, chapters illustrate the complexity of the management of pediatric lens opacities. The book closes with a case-based approach to special considerations in IOL implantation: including considerations in the uveitic patient, placement without capsular support, and cataract surgery in the developing world. Providing thoughtful chapters that seek to expand on the currently available literature without redundancy, this book a solid companion piece to any other text discussing pediatric cataracts.




Innovative Implantation Technique


Book Description

This book provides a complete overview of the bag-in-the-lens implantation technique written by the pioneering force herself. The technique first developed for the adults and later for paediatrics has had overwhelmingly positive outcomes in reduction of posterior capsular opacification and stability. Nowadays, it is used as a primary approach in all patients with cataract. The initial version of the bag-in-the-lens implant is a monofocal spherical hydrophilic intraocular lens comprised of a 5mm bi-convex optic with two elliptical plane haptics. Bag-in-the-Lens Cataract Surgery guides through the steps required to achieve successful implantation in a concise and highly illustrated format to portray how to effectively perform this surgery. The toric version was launched in 2009 and the diffractive version is on its way. New and experienced ophthalmic surgeons will find this guide to be an indispensable resource for utilizing this technique to successfully treat adult and paediatric cataract patients in their daily clinical practice.

The Intraocular Implant Lens Development and Results with Special Reference to the Binkhorst Lens


Book Description

Until 1-1-1972 DINKHORST inserted 170 iridocapsular lenses in 158 patients. The first operation took place on 16-9--1965*. Initially, indication for the fitting of an iridocapsular lens was congenital or traumatic cataract in children, since the e~tracapsular cataract extraction necessary at that age, facilitated iridocapsular fixation (DINKHORST, 1967ac; DINKHORST & GODIN, 1967d, 1970b, 197lb, 1972d). After 1970 MANSCHOT's histopathological findings (see Chapter VIII) and the desire to reduce disloca tions and the development of ECD to a minimum induced DINKHORST to per form primary iridocapsular lens implant operations in cases with senile cataract as weH. This explains the decrease in the fitting or iris clip lens implants in favor ofiridocapsular lens implants (see Fig. 39). The distribution ofthe patients' ages in these 170 cases is, therefore, quite different from that of the 677 iris clip lens implant operations (see Fig. 40). The technique ofthe iridocapsular lens implantation is described on page 59. Numerical data are shown in Fig. 41. Noteworthy in this table are the following points: 1. The average age at operation of 30.82 years which is very low compared with the 65.80 years for the iris clip lens series, may be explained by the relatively !arge nurober of children in this series (see Fig. 40).
