Fig. 3From: Thickness changes in the corneal epithelium and Bowman’s layer after overnight wear of silicone hydrogel contact lensesCorneal epithelial thickness after overnight contact lens (CL) wear. Compared to the lens insertion level, the epithelial thickness of the lens-wearing eye increased at eye opening (P = 0.001). The epithelial thickness of the non-CL-wearing left eye did not change at waking (P > 0.05).*: P < 0.05, compared with the lens insertion levelBack to article page
