Valley Contax is happy to offer the Tangible Hydra-PEG coating as an option to all of our lenses manufactured in Contamac Optimum materials. This advanced technology is applied to the lens at the final stage of manufacturing and helps solve the issues of lens comfort and dry eyes by:

  • Improving wettability
  • Increasing lens surface water retention
  • Increasing lubricity/smooth feeling of the lens
  • Minimizing deposits and lens fogging

Hydra-PEG illustration

Tangible Hydra-PEG is a hydrophilic coating that is permanently bonded to the surface of the lens and lasts the life of the lens and has been FDA approved for use on the Contamac materials Extra and Extreme. The coating is ultra-thin at less than 50 nanometers and thus does not alter lens geometry, mass or Dk/t. It also does not inhibit oxygen permeability or light transmission.

Adding Tangible Hydra-PEG technology to the Custom Stable, the first scleral lens approved by the FDA for the treatment of dry eye, is a sure fire way to get the most comfort and visual acuity for your patients.
