The optokinetic response is effective to assess objective visual acuity in patients with cataract and age-related macular degeneration

Purpose To estimate objective visual acuity in subjects suffering from cataract and age-related macular degeneration via the optokinetic response evoked by a non-conventional induction method (oktotype); in addition, to compare such objective outcome with the subjective acuity based on the ETDRS charts.
