dc.description.abstractIn this research, it was decided to carry out a bibliographic search on how optical aberrations affect patients with keratoconus and how their correction with contact lenses helps to improve their visual quality, in order to find the best contact lens with better results when moment of their adaptation, identify the optical aberrations that occur more frequently in people with keratoconus and establish the improvement of contrast sensitivity after correction of the aberrations, it also seeks to provide better information to the health community eye on optical aberrations in patients with keratoconus, and thus achieve an adequate and personalized treatment for each patient. To do this, 36 articles containing information on keratoconus, contact lenses, optical aberrations and contrast sensitivity were reviewed, they were divided into 4 types of contact lenses, soft contact lenses, rigid gas permeable contact lenses, hybrid contact lenses and scleral contact lenses. As a result, it was found that the contrast sensitivity improved significantly with the 4 different contact lenses, except with the rigid lens, which showed improvement in 66%, the aberrations that were found more frequently were the aberration of coma, trefoil and spherical aberration, regarding the best contact lens for the correction of aberrations, it was concluded that soft contact lenses reduce aberrations in primary stages of keratoconus, the rigid contact lens helps in moderate to advanced stages, and Sclerar contact lens shows significant improvement in severe stages.eng
dc.description.abstractEn esta investigación se optó por realizar una búsqueda bibliográfica sobre cómo afectan las aberraciones ópticas en los pacientes con queratocono y cómo su corrección con lentes de contacto ayuda a mejorar su calidad visual, con el fin de encontrar el mejor lente de contacto con mejores resultados al momento de su adaptación, identificar las aberraciones ópticas que se presentan con mayor frecuencia en las personas con queratocono y establecer la mejora de la sensibilidad al contraste luego de la corrección de las aberraciones, también se busca dar una mejor información a la comunidad de la salud ocular sobre las aberraciones ópticas en los pacientes que presente queratocono, y así lograr ofrecer un tratamiento adecuado y personalizado a cada paciente. Para ello, se revisaron 36 artículos que contenían información sobre queratocono, lentes de contacto, aberraciones ópticas y sensibilidad al contraste, se dividieron en 4 tipos de lentes de contacto, lentes de contacto blandos, lentes de contacto rígidos gas permeables, lentes de contacto híbridos y lentes de contacto esclerales. Como resultado se encontró que la sensibilidad al contraste mejoraba significativamente con los 4 diferentes lentes de contacto, excepto con el lente rígido, el cual demostró mejoría en un 66%, las aberraciones que se encontraron con mayor frecuencia fueron la aberración de coma, trefoil y la aberración esférica, en cuanto al mejor lente de contacto para la corrección de las aberraciones, se concluyó que los lentes de contacto blandos disminuyen las aberraciones en estadios primarios del queratocono, el lente de contacto rígido ayuda en estadios de moderados a avanzados, y el lente de contacto esclerar muestra una mejora significativa en estadios severos.spa
