Fig. 5From: Thickness changes in the corneal epithelium and Bowman’s layer after overnight wear of silicone hydrogel contact lensesTotal corneal thickness after overnight contact lens (CL) wear. Compared to baseline, the total corneal thickness of the lens-wearing right eye increased at waking the next day (P = 0.003) and recovered 30 min later (P = 0.555). In contrast, the total corneal thickness of the non-CL wearing left eye did not increase at waking (P = 0.105). *: P < 0.05, compared with baselineBack to article page
