Lenticular Cu, Zn and Fe contents were measured by graphite furnace atomic absorption spectrophotometer. In the senile cataractous lenses, Fe accumulation were approximately 3 times, Cu 6 times and Zn 1.5 times more than the normal lenses. In the diabetic cataractous lenses, Fe accumulation were approximately 5, Cu 6 and Zn 1.5 times higher than the normal lenses. Increase in Fe content was significant (p<0.01) while Cu and Zn was not in diabetic cataractous lenses when compared to the senil cataractous lenses. There were positive correlations between Cu and Zn (r=0.602, p<0.05), Fe and Zn (r=0.633, p<0.05) in diabetic cataractous, and between Zn and Fe levels in senile cataractous lenses (r=0.917, p<0.001). Further studies would be needed to describe why the elements precipitates so much in cataractous lenses and by which mechanisms they cause cataractogenesis.Keywords: Senile cataract, diabetic cataract,
