With scleral lenses, higher lens thickness and also the fluid layer at the rear of the lens could lead to indications of corneal hypoxia. It's believed that the superior-Dk materials and thin models of modern scleral lenses will eliminate this hypoxic effect from the cornea, but there is not any evidence demonstrating this definitively. Despite the fact that a scleral lens with a Dk of 100 will theoretically have sufficient oxygen permeability, the Dk of tears is only eighty; therefore, the thickness in the tear reservoir behind the scleral lens may well lessen its oxygen permeability.
The commonest kind of hard contact lens is often a rigid gas-permeable (RGP) lens. These lenses usually are created from plastic coupled with other materials. They hold their form firmly, still they let oxygen circulation in the lens in your eye.

It is usually recommended that corneal clearance must Preferably be in between a hundred and three hundred µm while in the central zone. Reduced central clearance ends in increased oxygen transmission, greater Visible acuity, and less bubble formation.
