Dr. Holladay discusses what's on everyone's mind: - How to take the best measurements and perform the best calculations to ensure good outcomes in cataract and refractive surgery - How neural adaptation can improve outcomes - How today's excimer laser systems deliver excellent optical correction, and why tomorrow's systems will perform even better Quality of Vision: Essential Optics for the Ophthalmic Surgeon is the most complete and practical reference for ophthalmologists looking to increase their understanding of optical physics and their ability to deliver good vision to their patients after cataract and refractive surgery.

Download or read book Making Eye Health a Population Health Imperative written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-01-15 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.

Download or read book Visual Impairments written by National Research Council and published by National Academies Press. This book was released on 2002-08-17 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.

Download or read book Social Quality A Vision for Europe written by Laurent Van der Maesen and published by Kluwer Law International B.V.. This book was released on 2001-01-31 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents the outcome of two years of intensive debate about the future of Europe. It aims to provide the European Union with a vision: one that will unite all of its citizens and help to create the democratic legitimacy that the EU currently lacks. It builds on the first book on social quality, The Social Quality of Europe, which introduced the concept and which has been enthusiastically received by both the scientific and policy communities. The book develops three crucial elements of social quality: the theoretical validity of the concept, its practical application, and its identity or `genetic code'. It establishes an independent identity for social quality, with a unique focus on the quality of the social, which enables it to act as the rationale for economic, social, and cultural policies and, therefore, an escape route from the dominance of narrow economic thinking in policy making.

Download or read book Addressing the Unmet Needs of Cataract Patients When Quality of Vision Can Make the Difference in Quality of Life written by Rita Mencucci and published by Frontiers Media SA. This book was released on 2023-10-13 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the ageing population, the need for cataract surgery is increasing very steeply in line with demographic change. Cataract surgery is a highly successful and cost-effective intervention, but the implantation of conventional monofocal intraocular lenses (IOLs) only allows a restoration of distance vision, with minimal postoperative functionality of near and intermediate vision, which are necessary for many common daily tasks. Although the removal of the opacified crystalline lens has been demonstrated to have a very positive impact on the mental health, daily functioning, and Quality of Life (QoL) of patients, it is not surprising that the poor visual restoration achieved with conventional monofocal IOLs at different near and intermediate distances might limit patient functioning and consequently QoL, considering changing lifestyles and increased working years. Therefore, this has led to a growing interest toward IOLs that may also reduce spectacle dependence for intermediate and near distances.

Available in PDF, EPUB and Kindle. Book excerpt: Today, quality is the battleground on which global competition takes place, yet without effective leadership no quality program can succeed. This penetrating book exposes the problems that arise when leadership in business fails to do its job, and offers powerful, inspirational examples of firms that have confronted this problem and prevailed through leadership that aims at producing quality results. By highlighting the practices of such noted leaders as Walt Disney and Michael Eisner at Walt Disney, Ray Kroc at McDonald's, Sam Walton at Wal-Mart, David Kearns at Xerox, and Robert Galvin at Motorola, the authors reveal how each of these legendary leaders possessed three crucial leadership characteristics -- vision, strong values and beliefs, and the active courage to make their visions a reality. These characteristics, they show, make the difference between superior performance and "business as usual." With eloquent case studies, the authors demonstrate that unusually successful business leaders show the way for their employees by nurturing cultures that encourage and reward quality performance and by exhibiting personal characteristics that inspire excellence. A leader dedicated to a single vision, the authors show, inspires personal commitment to a common purpose. Walt Disney had a vision of a company that would never stop creating, innovating, and growing. Values and beliefs serve as the basis for direction and action in a business. Superior leaders, the authors argue, are expert in the promotion of values -- such as Ray Kroc's obsession with high-quality, inexpensive food in a clean environment. The courage to make things happen is exhibited most dramatically by Sam Walton's perseverance in mass market retailing. The payoffs for these superior leaders included the loyalty and commitment of their employees, quality, and profits. The authors' approach to leadership for quality management -- with its focus on vision, values, and courage -- emphatically demonstrates what leaders must do to consistently produce quality results if they want their organizations to prosper and grow.
