Vascular response to extended wear of hydrogel lenses with high and low oxygen permeability.


PURPOSE The purpose of this study was to determine the impact of extended wear of high and low oxygen permeability (Dk) lenses on the development or resolution of limbal hyperemia and corneal neovascularization in a randomized prospective clinical trial. METHODS Adapted daily-wear contact lens wearers were randomly assigned to one of two groups. The low… (More)
