Book excerpt: OBJECTIF: Etudier l'effet de l'implantation d'une lentille intraoculaire (IOL) torique pour la correction de l'astigmatisme cornéen préexistant dans la chirurgie de la cataracte, et le retentissement visuel, réfractif et abérrométrique de son désaxement. MATERIEL ET METHODE: Cette étude prospective observationnelle a inclus 30 yeux de 20 patients consécutifs, avec plus de 1,5 dioptrie d'astigmatisme cornéen, candidats à une chirurgie de la cataracte. L'implantation d'une lentille de type Acrysof toric (Alcon) ou AT TORBI 709M (Cari Zeiss) a été réalisée après phacoémulsification. L'acuité visuelle sans correction (AVSC), la meilleure acuité visuelle corrigée (MAVC), la sphère réfractive, le cylindre réfractif et kératométrique, l'axe de la IOL et les aberrations de haut degré ont été mesurés. RESULTATS: À un mois postopératoire, l'AVSC était de 0,15 logMAR avec une AVSC inférieure à 0,3 logMAR dans 96,6% et inférieure à 0,1 logMAR dans 46,6%. Le cylindre réfractif moyen a diminué significativement après la chirurgie de 2,93 D ± 1,19 à 0,95 D ± 0,53 (Pc.OOOl) avec un cylindre réfractif inférieur ou égal à 0,5 D dans 50% des cas. L'axe moyen de rotation de la IOL était de 6,86 ± 6,12 degrés. Il a été retrouvé une corrélation linéaire positive significative entre le désaxement de la IOL torique et l'AVSC (P=.0149, i?2=0,217) ainsi que le cylindre résiduel réfractif (P=.012, i?2=0,213). Il n'a pas été retrouvé de corrélation entre le désaxement et les aberrations optiques de haut degré, totales et individuelles. CONCLUSION: L'implantation torique en chambre postérieure dans le cadre de la chirurgie de la cataracte est une technique efficace et sûre pour corriger l'astigmatisme cornéen préexistant. Le mauvais alignement de la IOL torique induit une diminution des résultats visuels et réfractifs, sans altération de la qualité optique visuelle.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

In fact, this chronic eye disease affects 1 percent to 3 percent of the population of the Western world age 40 and over, and its incidence increases with age-reaching 10 percent in people over 80. Glaucoma is an extremely insidious disease. It can destroy the functional capacity of the eyes irreversibly and without warning. Screening is thus a major issue in the fight against glaucoma, especially as there are effective treatments that can prevent or slow progression of the disease. Written in simple and clear language by doctors specializing in eye disorders, this book covers all aspects of the disease and provides important information for those who have glaucoma and the people close to them: The different forms and symptoms of glaucoma Known causes and risk factors Diagnostic tests Prevention Drug therapies, laser treatments and surgical procedures Daily living with glaucoma Treatments of the future 25 most frequently asked questions (FAQs) about glaucoma Useful addresses

Available in PDF, EPUB and Kindle. Book excerpt: Each year the improvements in communication and transportation, the growing awarness that the resources of this earth are finite, the realization that the population explosion in any part of the world is a concern of all, and the increased economic interdependence of all countries, have increased importance of internationalism as opposed to nationalism. One of the first segments of our society to ignore political and geographic boundaries was that of medicine, particularly in the field of communicable diseases. Valient efforts have been made by some individuals at great personal sacrifice and by individual societies or organizations to prevent and cure blindness and to rehabilitate those who have lost their sight. Only recently, however, have such efforts been consolidated into a major international force. In 1969 the 22nd World Health Assembly of WHO adapted a resolution requesting the Director-General to undertake a study on the information which is at pre sent available on the extent and/or causes of preventable and curable blind ness. In 1972 a working group was convened by the World Health Organiza tion in Geneva to outline an attack on the prevention of blindness. At the Paris meeting of the International Congress of Ophthalmology in July of 1974, Mr. JOHN WILSON, who for many years had been one of the leaders in the prevention and cure of blindness on an international basis through his organization of the Royal Commonwealth Society for the Blind, was elected President of the International Association for Prevention of Blindness.

Available in PDF, EPUB and Kindle. Book excerpt: La chirurgie de l’œil a effectué des progrès considérables au cours des vingt dernières années grâce à la microchirurgie et à l’utilisation du laser. Elle permet aux myopes, aux hypermétropes et aux astigmates de ne plus porter de lunettes. La chirurgie de la cataracte est la plus fréquente : 400 000 interventions tous les ans ! Elle est surtout devenue beaucoup plus simple et permet de recouvrer très vite une bonne vision. Face au glaucome, de nouveaux traitements médicamenteux permettent de retarder, voire de supprimer, l’acte chirurgical. La dégénérescence maculaire est à l’origine de la malvoyance chez de nombreuses personnes âgées. Elle peut désormais être stabilisée par le laser. Le Dr Yves Bokobza présente les principales urgences en ophtalmologie ; il décrit le diagnostic et le traitement de l’ensemble des pathologies oculaires. Afin d’aider chacun à conserver ce capital inestimable qu’est la vision. Le Dr Yves Bokobza est ophtalmologiste. Spécialisé dans la chirurgie de l’œil et de la myopie en particulier. Professeur associé au Collège de médecine, il exerce à l’hôpital Ambroise-Paré à Boulogne-Billancourt.

Available in PDF, EPUB and Kindle. Book excerpt: A concise review and comprehensive guide to improving cataract surgery outcomes Significant advances have been made in refractive surgery in the last decade. Eye surgeons today can leverage many cutting-edge intraocular lens (IOL) technologies such as multifocal, extended depth of field, toric, accommodating, and aspheric. Concurrent innovations including optics, phacoemulsification, superior keratometry and biometry, and posterior cornea evaluation have resulted in improved cataract surgery outcomes. Recent advances in the diagnosis and treatment of cataracts have dramatically improved patient satisfaction following cataract surgery, yet common and rare complications still occur such as dry eye, endophthalmitis, and retinal detachment. Furthermore, only 80% of cataract surgery procedures bring patients to within 0.5 diopters of their needed refraction. Optimizing Suboptimal Results Following Cataract Surgery: Refractive and Non-Refractive Management presents the latest techniques for achieving optimal results and overcoming complications in cataract surgery. Internationally renowned ophthalmic surgery pioneers Priya Narang and William Trattler have created an unparalleled guide to overcoming complex cases and residual refractive errors. The book starts with six chapters on suboptimal causes and considerations, followed by dedicated sections covering refractive and non-refractive enhancements. The fourth section features chapters on keratoconus, cystoid macular edema, endophthalmitis, toxic anterior segment syndrome, and vitritis, as well as intraoperative aberrometry, futuristic approaches and advancements, and telescopic IOLs. Key Highlights Refractive enhancement procedures including corneal-based procedures such as astigmatic keratotomy, LASIK, PRK, and SMILE; IOL exchange; piggyback IOL; toric IOL; and premium IOLs and associated problems Nonrefractive enhancement procedures including dysphotopsias and surgical management, bullous keratopathy and endothelial keratoplasty, complex IOL issues such as malpositioned IOL and capsular bag, and posterior capsular rupture and IOL lens implantation Practical tips and steps to prevent and manage undesired outcomes 30 surgical videos posted online highlight a diverse array of complex cases and technical advances to help prevent suboptimal results Ophthalmologists, ophthalmology residents, fellows, and subspecialists will greatly benefit from the significant pearls and knowledge presented in this indispensable cataract surgery resource.
