Background: Cataract patients were always excluded from studies on ageing of colour vision; thus, effect of agerelated\ncataracts on deterioration of colour perception has not been analysed. In present study, impacts of agerelated\ncataracts on colour discrimination, postoperative recovery and related spectra were investigated.\nMethods: In this cohort study, thirty age-related cataract patients scheduled for binocular surgery and 30 elderly\nvolunteers were enrolled. Colour discrimination under photopic (1000 lx) and mesopic (40 lx) conditions was evaluated\nwith Farnsworth-Munsell 100-hue test. The total error score (TES) and partial error score (PES) were calculated.
