Book Synopsis Lentes de contacto en ectasias by : Ortega Pacific, Ernesto
Download or read book Lentes de contacto en ectasias written by Ortega Pacific, Ernesto and published by Universidad de la Salle. This book was released on 2020-08-13 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Las ectasias son córneas irregulares primarias. La adaptación de lentes de contacto para pacientes con este tipo de dolencia pertenece a las adaptaciones especiales. Especiales no precisamente por el diseño de los lentes, muchos pacientes con ectasias pueden corregirse con los mismos diseños que se utilizan para la gran mayoría de los demás pacientes. Lo especial radica en la manera en que debe evaluarse al paciente. Las adaptaciones son comúnmente más complejas por tener córneas irregulares y debe disponerse de un buen número de lentes de prueba con diferentes diseños. Por lo mismo, el tiempo que ha de dedicarse a cada paciente es mayor que el de las adaptaciones convencionales. Se requiere conocer el perfil corneal, de manera cualitativa y cuantitativa, y por lo mismo es necesario apoyarse en topografía corneal convencional o Plácido, o de elevación o tomografía corneal.
Book Synopsis Interpretación de la topografía corneal y la adaptación de los lentes de contacto rígidos by : Ortega Pacific, Ernesto
Download or read book Interpretación de la topografía corneal y la adaptación de los lentes de contacto rígidos written by Ortega Pacific, Ernesto and published by Universidad de la Salle. This book was released on 2011-06-16 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Esta analiza la adaptación de los lentes de contacto rígidos, a partir de la práctica desarrollada por el autor como profesional en la atención de pacientes, en la docencia y por medio de la investigación. El primer capítulo trata sobre la adaptación de lentes de contacto rígidos en casos convencionales: hipermetropías, miopías y astigmatismo, en ausencia de ectasias corneales y otro tipo de irregularidades que, en estos tiempos, obligan a apoyarse en otras tecnologías como la topografía corneal computarizada. El segundo está enfocado en la comprensión e interpretación de la topografía corneal. Se ofrecen algunos conceptos básicos para que un principiante, sin mayor conocimiento en la temática, pueda utilizar de modo adecuado esta importante herramienta, básica para adaptaciones de lentes especiales. El tercer capítulo presenta algunos aspectos de las dos investigaciones dirigidas y desarrolladas por el autor, relacionados con la adaptación de lentes de contacto rígidos, apoyándose en la interpretación del mapa topográfico. La primera trata sobre la identificación del tipo de queratocono, analizando el tamaño de la ectasia, para seleccionar, de acuerdo con esta, el diseño de la curva base y el diámetro. La segunda, la selección de los parámetros principales de adaptación de lentes rígidos de curva base esférica para pacientes con córneas irregulares posteriores a cirugía refractiva de tipo láser.

Book Synopsis Adaptación de lentes de contacto en córneas irregulares by : Ernesto Ortega Pacific
Download or read book Adaptación de lentes de contacto en córneas irregulares written by Ernesto Ortega Pacific and published by Universidad de la Salle. This book was released on 2019-12-20 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: La adaptación de lentes en córneas regulares se está utilizando desde hace más de medio siglo, y para ello están dispuestos todo tipo de lentes de contacto blandos, híbridos, rígidos y de apoyo escleral. Cuando las córneas son irregulares debido a una deformación en su cara anterior —la más conocida por todos, el queratocono—, la adaptación de los lentes se complica y debe realizarse con ayuda de aparatos que ofrezcan información de todo el perfil corneal, como los topógrafos o tomógrafos corneales. La cirugía refractiva es en general un gran logro de la oftalmología, y Colombia es uno de los países en donde se tienen mayores desarrollos sobre este caso particular. Algunas veces, por inconvenientes en la adecuada selección del paciente, problemas en el desarrollo de la cirugía u otro tipo de problemas posteriores, quedan pacientes con córneas irregulares que no logran buena visión con anteojos y que deben ser adaptados con algún diseño especial de lentes de contacto de apoyo corneal o escleral. Para estas adaptaciones es muy importante la adecuada interpretación de las imágenes topográficas y tomográficas de cornea.

Book Synopsis Contact Lenses in Ophthalmic Practice by : Mark J. Mannis
Download or read book Contact Lenses in Ophthalmic Practice written by Mark J. Mannis and published by Springer Science & Business Media. This book was released on 2006-05-11 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even with the advances in intraocular lens technology and the growing diversity of refractive surgery techniques, the role of contact lenses in ophthalmic practice has only increased. This is due in part to the great strides in materials, technology, expanding applications (both refractive and therapeutic) for contact lenses, and the clear recognition that contact lenses will always be an important tool for the ophthalmologist. With the fitting of contact lenses as a medical art, requiring a thorough understanding of anatomy, physiology and optics of the eye, this practice is formulaic only in part. The rest of contact lens practice requires sound medical judgment and decision- making that comes only with "hands-on" experience. The authors address this need by starting with a didactic approach that incorporates frequently-asked questions and straightforward answers so that the ophthalmology resident, intermediate contact lens practitioner, and optometrist will find this to be an indispensable resource.
Book Synopsis Refractive Surgery with Phakic IOLs by : Jorge L Alio
Download or read book Refractive Surgery with Phakic IOLs written by Jorge L Alio and published by JP Medical Ltd. This book was released on 2012-10-30 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phakic IOLs (intraocular lenses) are surgically implanted lenses used for the permanent correction of common vision errors such as myopia (short-sightedness). These implants, which resemble contact lenses, are placed either between the cornea (the clear lens in front of the eye) and the iris (the coloured part of the eye), or just behind the iris. This second edition provides a comprehensive review of the technology and clinical indication of phakic IOLs, their contraindications, how to handle surgical complications and practical issues in their use in refractive surgery. Divided into two parts, the first section discusses the basic principles of refractive surgery with phakic IOLs and the second part examines their implantation including for astigmatism correction, combined and additive procedures and new trends. Key Points Comprehensive review of technology and clinical indication of refractive surgery with phakic IOLs Examines basic principles and implantation techniques Authored by highly experienced ophthalmic specialists in Europe and the USA First edition published in 2003
Book Synopsis Atlas of capillaroscopy in rheumatic diseases by : Maurizio Cutolo
Download or read book Atlas of capillaroscopy in rheumatic diseases written by Maurizio Cutolo and published by Elsevier srl. This book was released on 2015-09-30T00:00:00+02:00 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary Raynaud phenomenon, as clinical symptom of altered peripheral microcirculation, affects 5ˆ15% of individuals in the general population and almost 15% of cases will shift from the primary to the secondary phenomenon (associated with the systemic sclerosis and other connective tissue diseases) in a mean time of 29.4±10 months. Nailfold videocapillaroscopy (NVC) represents the safest, noninvasive, less expensive and reliable method to analyze microvascular abnormalities in systemic sclerosis and the findings can be scored and quantified. Since microvascular damage and dysfunction represent early markers of systemic sclerosis and are clinically mirrored by secondary Raynaud phenomenon, the diagnostic, prognostic and therapeutic implications of microvessel morphological analysis by NVC enables the best clinical management. Reduced capillary density on NVC predict and correlates with a high risk of developing digital skin ulcers and the presence of pulmonary arterial hypertension, and can therefore be used as a marker of systemic sclerosis severity and progression, as well as to monitorize the therapeutical effects. Growing interest and intense recent research on capillaroscopy have resulted up to 2010 in almost 350 papers reported in PubMed in the last 10 years, accounting for almost 50% of the total number of publications on the subject from 1951. However, an atlas explaining the capillaroscopy in rheumatic diseases in a modern, updated and physiologically-based way with large discussion of clinical cases was lacking and is now available. The authors of the atlas have been selected among the best international experts of the field and are all members of the board of the international courses on capillaroscopy supported by the European Ligue Against Rheumatic Diseases (EULAR). The reader after a carefull and progressive analysis of the text will learn to understand the capillaroscopic findings that characterize the most important rheumatic diseases and will use the atlas for his daily clinical practice.
