摘要:
A method for designing an intraocular lens capable of adjusting the aberrations of the eye in order to provide optimal vision correction to patients consisting of the following elements: - A mathematical model eye that describes the optical setup and performance of the human eye natural, comprising at least one corneal aspheric surface, an index gradient and / or a lens model crystalline aspheric, a visual axis that is inclined relative to the axis of the "optical axis" of symmetry of the eye and an iris decentered that It represents a decentered entrance pupil. - Determination of the efficiency of the mathematical model eye in terms of image quality and spherical aberrations depending on the pupil diameter. - Using a mathematical model that describes the statistics of potential lens misalignments and positioning errors induced by surgery or processes of wound healing. - Calculation of the optical performance and resulting aberrations employing said mathematical model eye combined with the statistical model for lens displacements. - and optical modeling of a form of spherical lens that replaces the natural human crystalline in the eye that provides recovery of the optical power, while providing optical characteristics of the human lens in order to make the eye with the intraocular lens has a spherical shape having the same amount of spherical aberrations and the same level of image quality that the mathematical model eye in fusion pupil diameter.Método para diseñar una lente intraocular capaz de ajustar las aberraciones del ojo con el fin de proporcionar una corrección óptima de la visión a pacientes que consta de los siguientes elementos: - Un modelo matemático del ojo que describe la estructura óptica y la actuación del ojo humano natural, que comprende al menos una superficie corneal asférica, un índice de gradiente y/o un modelo de lente de cristalino asférico, un eje visual que está inclinado con respecto al eje del "eje óptico" de simetría del ojo y una iris d
