Effect of aspherical and yellow tinted intraocular lens on blue-on-yellow perimetry

Abstract: Purpose:To investigate the possible effect of aspherical or yellow tinted intraocular lens (IOL) on contrast sensitivity and blue-on-yellow perimetry. Methods: This prospective randomized bilateral double-masked clinical study included 52 patients with visually significant bilateral cataracts divided in two groups; 25 patients (50 eyes) received aspherical intraocular lens in one eye and spherical intraocular lens in the fellow eye; and 27 patients (54 eyes) received ultraviolet and blue light filter (yellow t… Show more

“…In case the initial doubt had already been clarified (published), the expertise acquired about the subject will allow to discover a "gap" in knowledge, which could yet be studied in an unprecedented way. For example, If the original doubt is about the possibility of an aspheric intraocular lens (when improving the visual perception of contrast) influence in diagnostic exams that use the sensibility to contrast and if this doubt had already been responded to the blue-yellow visual field exam, a possible "gap" would be question if the findings were also valid for other types of exams (FDT, for instance) or other types of aspheric lenses (4,5).…”

“…En cuanto a la medida clínica de la agudeza visual y la sensibilidad al contraste, no solo se ha obtenido una mejora significativa de las mismas tras la cirugía de cataratas, sino que el filtro amarillo no afecta negativamente, hallazgos que coinciden con los de otros autores (Alexander et al, 2014;Bandyopadhyay et al, 2016;Díez-Ajenjo et al, 2014;Espíndola et al, 2012;Lavric et al, 2014;Rodríguez-Galietero et al, 2005). Aunque este efecto se ha observado 45 días después de la cirugía, no obstante autores como Kara-Junior et al ( 2011) constatan la persistencia de los resultados un año después de la intervención.…”
