UltraHealth hybrid contact lenses manufactured by SynergEyes combine a highly oxygen-permeable rigid center with a soft peripheral silicone hydrogel "skirt."

This hybrid lens was designed specifically for keratoconus, where the central gas perneable zone of the lens vaults over the cone-shaped cornea for increased comfort.

Hybrid contact lenses provide the crisp optics of a gas permeable contact lens, and the wearing comfort that rivals that of soft lenses, according to SynergEyes.

UltraHealth hybrid lenses are available in three curves: flat, medium, and steep to guarantee centration, patient comfort, and provide a fit that conforms well to the irregular shape of a keratoconic eye.
