The issue of hydrophilicity of the surface of gas permeable contact lenses remains one of the persistent problems. Tangible Hydra-PEG™ surface coating is applied to gas permeable contact lenses to significantly improve wettability and wearing comfort. Although it is mainly used to alleviate dry eye symptoms in scleral and corneal lens users, particularly for those patients with corneal ectasia and/or Ocular Surface Disease (OSD), it can be used in other modalities. This article describes the development of the product and describes the benefits of its use in a clinical case.
