This comprehensive 2nd edition will build on the highly successful first edition, providing an updated global perspective of the fundamentals of multifocal intraocular lenses. The varying outcomes, limitations, and the neuroadaptation process necessary for an adequate clinical success are thoroughly discussed, along with an overview of the different types of multifocal lenses, including the recently developed extended depth of focus lenses.Multifocal Intraocular Lenses: The Art and the Practice, 2nd edition opens with an introduction that will delve into current technological offerings for the correction of pseudophakic presbyopia, as well as the opportunity for refractive lens exchange in advanced presbyopic ages and the opportunity to use these lenses.  The first section will include the historical background and clinical indications, while section two addresses the varying types and models of lenses currently available, including important clinical and technological highlights. Section three and four will follow, and provide an extended look at the Zeiss and Alcon Family Multifocal IOL’s. Section five will delve into extended depth of field lenses, and will contain an introduction about the concept, different models and the evidence available about their outcomes. Section six concludes the book, closely examining accommodative intraocular lenses, and a full update will be provided on these lenses, the failures of the past and the hopes for the future. Multifocal Intraocular Lenses: The Art and the Practice, 2nd edition is a thorough, resource for the practical ophthalmologist and ophthalmic surgeon interested in learning more about intraocular lenses, identifying the best technologies and lenses for the benefit of their patients.

 IOL Power by Kenneth J. Hoffer, MD will be the definitive resource worldwide for ophthalmologists who strive to increase the accuracy for all IOL calculations,especially for multifocal IOLs and overcoming the challenges that arise when treating patients that have had laser refractive surgery, such as RK, PRK, LASIK, and LASEK.Inside the pages of IOL Power, Dr. Hoffer is joined by some of the most respected international physicians and physicists in the field of IOL power such as Aramberri, Haigis, Norrby, Olsen and Shammas. Together their expertise, spanning over 35 years, makes even the most difficult subjects easy to understand.This volume will become the definitive reference source on the subject of IOL power calculation.Some topics include: · Ultrasound velocities for axial length measurement· Optical AL (IOLMaster and Lenstar) in difficult eyes· Manual and automatic keratometry and instrumentation· Topography & Scheimpflug camera corneal power· Value of theoretic formulas· Formula personalization· Multifocal and toric IOLs· Aspheric IOLs· Effect of IOL tilt on astigmatismChapters Cover: · All aspects of obtaining the most accurate biometry· Available modern calculation formulas· Latest instruments · Problems that can arise, how to prevent and repair themIOL Power by Kenneth J. Hoffer, MD is structured in a logical manner so as to cover every facet of IOL power from the basics to the most complicated subjects to achieve the most accurate and precise calculations and should be in the hands of all ophthalmic surgeons, technicians, residents and students.

Abriendo tanto la cartografía como la polarizada taxonomía de la Guerra Fría, este libro plantea un análisis polifónico y multifocal de las prácticas artísticas, discursos estéticos y modelos de resistencia en el eje trasatlántico desde 1948 hasta hoy en día. A partir de una reflexión transversal y transnacional, los diferentes estudios que integran Atlántico Frío descentran el eje París-Nueva York, haciendo hincapié en procesos de transferencia e intercambio y su relación con las dinámicas socio-políticas, identitarias y postcoloniales que determinaron el conflicto global de la Guerra Fría. Esta obra participa en la necesaria revisión y cuestionamiento del papel de la cultura y del arte durante este período y propone una lectura renovada del rol que tuvieron artistas, críticos de arte, agentes culturales y exposiciones en el espacio tricontinental (de las Américas, de Europa del sur y de África) en la creación de redes culturales transnacionales, geografías disidentes y estructuras globales. Cuestionando las construcciones historiográficas de la Guerra Fría por largo tiempo centradas en la confrontación bipolar entre los bloques occidental y soviético, busca contribuir a una nueva cartografía de las prácticas artísticas en sus colaboraciones (y tensiones) con las prácticas políticas, a través de una lectura desde el Atlántico y el Sur global.
