The Flexlens (hioxifilcon A), (hioxifilcon B), (acofilcon A), (acofilcon B) Soft Contact Lens for Daily Wear (lathe-cut) are indicated for daily wear use for the correction of refractive ametropia and specialized use such as atypical ametropia. Examples include, but are not limited to: adult and pediatric aphakia, and irregular astigmatism created by keratoconus, trauma, or post keratoplasty. The Flexlens (hioxifilcon A), (hioxifilcon B), (acofilcon A), (acofilcon B) Harrison Post Refractive Surgery Soft Contact Lens for Daily Wear (lathe-cut) are indicated for daily wear use for the correction of refractive ametropia and specialized use such as atypical ametropia following corneal refractive surgery. The lens may be disinfected with a chemical (not heat) disinfection system.

The Flexlens and Harrison Post Refractive Surgery (hioxifilcon B), (acofilcon A), (acofilcon B) Soft Contact Lens for Daily Wear (lathe-cut) is fabricated from one of the above materials which in the dry (unhydrated) state may be machined and polished. The hydrophilic nature of this material allows the lens to become soft and pliable when immersed in an aqueous solution. In the hydrated state, the lens conforms to the curvature of the eve covering the cornea and extending slightly beyond the limbus forming a colorless, transparent optical surface. The hydrophilic properties of the lens require that it be maintained in a fully hydrated state in a solution compatible with the eye. If the lens dries out, it will become hard appear somewhat warped however, it will return to its proper configuration when completely rehydrated in the proper storage solution.
