Tangible Hydra-PEG is available on our complete line of FDA-approved, fully customizable scleral lenses. The addition of this polymer coating is especially useful in the patient with Ocular Surface Disease and Dry Eye. The coating completely encapsulates the lens, is ultrathin, and does not interfere with light transmissibility or oxygen permeability. It has been demonstrated to: improve wettability, increase surface water retention, increase lubricity, reduce deposits and fogging, and improve comfort.
