Ocular Surface Health during 30-Day Continuous Wear: Rigid Gas-Permeable versus Silicone Hydrogel Hyper-O₂Transmitted Contact Lenses

Abstract

Subclinical increases in epithelial permeability can be caused by contact lens CW, despite the elimination of hypoxia. GP lenses permit recovery of the epithelium more quickly than do SiH lenses. Asians appear to be more susceptible to contact lens-induced epithelial changes than do non-Asians.
