Ageing and Colour Discrimination after IOL Implantation

Overview

Colour discrimination was tested by FM 100-hue test in 106 patients (43 womenand 63 men) after implantation PMMA IOL to the posterior chamber. Examinedgroup of patients aged from 41 - 70 years was represented by 132 eyes. As a controlwere groups of healthy people (without hypertension and diabetes) of the sameage categories with physiological eye findings and still clear crystalline lens.After IOL implantation the resulting total score of the test in examined patientsof all decades was similar to the control group of healthy people. Even in healthypatients with IOL the colour discrimination is better beginning with 61 years (P< 0.05). Colour discrimination for red, green and blue colour has improved incomparison with the control groups and getting better with ageing. Clearly bettersensitivity was in the area of green colour, it was observed in the age group startingwith 61 years (P < 0.05) and for blue colour already since 51 years (P < 0.05).The improvement of colour discrimination in pseudophakic eyes in comparisonwith healthy population is slightly improving with increasing age.
