ClearKone and UltraHealth are similar in that they are both hybrid lenses that use the vault system for fitting. That is where the similarity ends. The two lenses have different materials, different GP designs and a different soft skirt design.

Materials:
UltraHealth is made with a GP material that provide 130 Dk of oxygen permeability compared to a 100 Dk of oxygen permeability of ClearKone. UltraHealth also includes both a UVA and UVB blocker, an important component for eye health especially in patients with irregular cornea conditions.

An even bigger increase in oxygen permeability comes with the new silicone hydrogel skirt of UltraHealth. The UltraHealth Dk is 84 for UltraHealth compared to 9.3 for ClearKone.
