Purpose: To assess optical quality dynamics using a double-pass (DP) system in patients with dry eye disease (DED). Methods: Seventy-six eyes with DED and 44 control subjects were enrolled in this study. Each patient underwent ocular surface evaluation including fluorescein corneal staining and Schirmer’s II test.
