Book Description
Good vision is more than 20/20 on a Snellen visual acuity chart. The modern ophthalmologist understands that contrast sensitivity, near and distance vision, performance under light and dark conditions, and the brain's interpretation of input from the sensory apparatus, are all important elements in patients' quality of vision. In Quality of Vision: Essential Optics for the Ophthalmic Surgeon, ophthalmologist and optics expert Dr. Jack T. Holladay explores the elements of vision that lie beyond Snellen testing. He explains the Quality of Vision addresses: - Measuring and treating astigmatism in corneal and IOL surgery - The importance of correcting spherical aberration in cataract and refractive surgery - IOL calculations after refractive surgery - Promising approaches to the correction of presbyopia - Other practical topics the clinician can use every day Recognized as the leader in ophthalmic optics, Dr. Holladay incorporates practical aspects of daily practice into each chapter as he expertly explains the scientific principles, mathematical formulas, and theories behind these important issues. Additionally, Quality of Vision includes numerous color illustrations to provide visual representations of the text's key points. 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.

Book Description
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.

Book Description
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.
