WebScleral Lenses 101. Designed to vault over the entire corneal surface and rest on the sclera, scleral lenses can morph an irregular cornea into a smooth optical surface to correct vision problems caused by keratoconus and other forms of corneal ectasia. Furthermore, the space between the cornea and the back of the scleral lens acts as a fluid ... WebJan 1, 2007 · Gas diffusion across a film is determined by film structure, thickness, area, concentrations gradient across the film, temperature, and differences in pressure across the film. In absence of cracks, pinholes, or other flaws, the primary mechanism for gas and water vapour flow through polymeric films is solution–diffusion mechanism.
