Oxygen diffusion and edema with modern scleral rigid gas permeable contact lenses [PDF]

, 2014
PURPOSE. We defined the theoretical oxygen tension behind modern scleral contact lenses (CLs) made of different rigid gas permeable (RGP) materials, assuming different thickness of the tear layer behind the lens.
