Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Medicine - Department of Ophthalmology Summary: Purpose: To determine the difference in the effect of different morphological types of cataract on visual acuity and contrast sensitivity. Methods: 119 eyes were enrolled in this prospective controlled study,of which 99 eyes with early senile cataract and 20 eyes of normal participants as control group. The 99 eyes of early senile cataract were categorized and graded according to the LOCS III with complete ophthalmological examination and were grouped into 3 groups. The first group is 33 with pure cortical cataract, the 2nd group is 33 with pure nuclear cataract and the 3rd group is 33 with posterior sub capsular cataract. Contrast sensitivity functionwas measured in patients with different cataract types using the F.AC.T chart with the 5 spatial frequencies (1.5, 3, 6, 12, &18) where the mean values at each spatial frequency in each type of cataract was plotted on the recording curve and with the Frequency doubling perimetry depending on its usage of the sine wave gratings while using the Mean deviation and Pattern standard deviation as correlative values, best corrected visual acuity was measured using the Snellen chart and recorded in decima
