Abstract
Description
El auge de la cirugía refractiva con excimer láser en las últimas dos décadas se ha reflejado en que un grupo creciente de paciente con antecedente de este procedimiento necesitan ahora cirugía de catarata. Debido a las modificaciones generadas en la córnea por la fotoablación con el láser, la determinación del poder corneal necesario para el cálculo del poder del lente intraocular a implantar en la cirugía de catarata, es difícil. Teniendo en cuanta estos aspectos se hace una revisión de las causas de estos errores de medición y los abordajes existentes para minimizar su impacto. MÉD.UIS. 2017;30(1):99-105.Palabras clave: Láseres de Excímeros. Queratectomía Fotorrefractiva. Topografía de la Córnea. Córnea.
