SCLERAL CONTACT LENSES AND CORNEA HYPOXIA

According to this study in Optometry and Vision Science:

The purpose of this study is to examine the change in corneal thickness and posterior curvature following 8 hours of miniscleral contact lens wear. Although a small amount of corneal swelling was induced following 8 hours of miniscleral lens wear, modern high Dk miniscleral contact lenses that vault the cornea do not induce clinically significant corneal edema or hypoxic–related posterior corneal curvature changes during short–term wear. Longer–term studies of compromised eyes are still required to inform the optimum lens and fitting characteristics for safe scleral lens wear to minimize corneal hypoxia.
