Amplitudes and implicit times of the flicker ERGs recorded with the RETeval™ system. Error bars are the standard deviations. a: Amplitudes of the flicker ERGs in the pseudophakic group, Grade 2 cataract group and Grade 3 cataract group. Amplitudes are significantly decreased in the cataract groups. b: The implicit times of the flicker ERGs of the pseudophakic group, Grade 2 cataract group, and Grade 3 cataract group. Implicit times are significantly prolonged in the cataract groups. Implicit times also show the significant difference between Grade 2 cataract group and Grade 3 cataract group
