  Results : The mean and standard deviation of ages of all the 600 patients' was 34.21±21 and for presbyopic patients was 55.53±10.9 years. Prevalence of presbyopia in total population was 41% and in population over 40 years, was 92.5%. From 246 presbyopic patients, 131 cases (53.3%) were females and 115 cases (46.7%) were males. There was a significant statistica l difference between the presbyopia patients compared to the other groups (p<0.0001) but this different between men and women was not significant (p= 0.23).
