Figure 5.

Corneal contour graphs for bicarbonate, lactate, glucose, pH, and carbon dioxide for the cornea during SL wear (A, C, E, G, I) and SCL wear (B, D, F, H, J). Oxygen permeability for both lenses is 100 Barrer; thickness profiles are provided in Figure 2. Only profiles in the cornea are provided, as the transport of most metabolites across the lens is minimal; the concentrations at the sclera are set to those of blood. The color legend for each row is directly below that respective row. Red color indicates high concentration, tension, or pH; and navy color indicates low concentration, tension, or pH. The unit of carbon-dioxide tension is mm Hg. Units of glucose, bicarbonate, and lactate are millimolar (mM).
