Method for producing an isoplanatic aspheric monofocal intraocular lens, and resul ting lens

Abstract

[ES] Permite obtener lentes oftálmicas monofocales asféricas isoplanáticas en un rango visual de hasta 25° (preferentemente hasta 10°) de amplitud. El procedimiento comprende las etapas de: l. -Defmición matemática de un modelo de ojo afáquico; 2.- Definición matemática de un modelo de lente intraocular; 3.- Defmición matemática de la implantación de la lente; 4. Definición matemática de la función de mérito; 5.- Definición de las condiciones de contorno; 6.- Defmición de una métrica para caracterizar la calidad óptica; y 7.- Optimización de la función de mérito. En esta invención, la métrica para caracterizar la calidad óptica considera, de manera novedosa, la combinación simultánea de varias posiciones de campo, preferentemente de forma ponderada.

[EN] The invention can be used to obtain isoplanatic aspheric mono focal intraocular lenses in a viewing range of up to 25° (preferably up to 10°). The method comprises the following steps: l. mathematical defmition of an aphakic eye model; 2. mathematical definition of an intraocular lens model; 3. mathematical defmition of the implantation of the lens; 4. mathematical defmition of the merit function; 5. definition of the contour conditions; 6. defmition of a measurement for characterising optical quality; and 7. optimisation of the merit function. According to the invention, the measurement used to characterise the optical quality considers, in a novel marmer, the sÍmultaneous combination of multiple field positions, preferably weighted.
