The AQUASOFT ALL-DAY (hioxifilcon A) Spherical Soft Contact Lenses for daily wear are indicated for the correction of visual acuity in aphakic and not aphakic persons with non-diseased eyes with myopia or hyperopia. The lens may be worn by persons who exhibit refractive astigmatism of 0.75 diopters or less where the astigmatism does not interfere with visual acuity. The lens may be cleaned and disinfected using a chemical (not heat) lens care system. The AQUASOFT ALL-DAY T (hioxifilcon A) Toric Soft Contact Lenses for daily wear are indicated for the correction of visual acuity in aphakic and not aphakic persons with non-diseased eyes with myopia or hyperopia and may have astigmatism of 7.00D of astigmatism or less. The lens may be cleaned and disinfected using a chemical (not heat) lens care system. Eyecare practitioners may prescribe the lenses for frequent/planned replacement wear, with cleaning, disinfection and scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be cleaned and disinfected using a chemical (not heat) lens care system.

The AQUASOFT ALL-DAY & ALL-DAY T (hioxifilcon A) Soft (hydrophilic) Contact Lens is available as a single vision spherical lens, and as a back surface astigmatic (toric) lens. The hydrophilic nature of this material allows the lens to become soft and pliable when immersed in an aqueous solution. The non-ionic lens material, (hioxifilcon A) is a random copolymer of 2-hydroxythyl methacrylate and 2,3 -dihydroxypropyl methacrylate, cross linked with ethylene glycol dimethacrylate. It consists of 43% hioxifilcon A and 57% water by weight when immersed in sodium carbonate buffered saline solution. The lens is available clear or with a blue visibility-handling tint, color additive 'Reactive Blue 19', 21 CFR part 73.2121. The United States Adopted Names Council (USAN) has adopted the (hioxifilcon A) name. In the hydrated state, the lens conforms to the curvature of the eye 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. The hydrophilic characteristics allow aqueous solutions to enter the lens and in its fully hydrated state the lens is approximately 57% water by weight.

The lens may be worn by persons who exhibit refractive astigmatism of .75 diopters or less where the astigmatism does not interfere with visual acuity. The lens may be cleaned and disinfected using a chemical (not heat) lens care system. The AQUASOFT (ocufilcon D) Toric Soft Contact Lenses for daily wear are indicated for the correction of visual acuity in aphakic and not aphakic persons with non-diseased eyes with myopia or hyperopia and may have astigmatism of 7.00D of astigmatism or less. The lens may be cleaned and disinfected using a chemical (not heat) lens care system. The AOUASOFT (ocufilcon D) Multifocal Soft Contact Lenses for daily wear are indicated for the correction of visual acuity in aphakic and not aphakic persons with non-diseased eyes with myopia or hyperopia and are presbyopic. The lens may be worn by persons who exhibit no more than 2.00 D of astigmatism and can obtain satisfactory visual acuity in a power range of +4.00D to -5.00D and have near add requirements up to 3.00D. The lens may be cleaned and disinfected using a chemical (not heat) lens care system. Eyecare practitioners may prescribe the lenses for daily wear for disposal after removal in a disposable lens program or for cleaning, disinfection and scheduled replacement in a frequent replacement program. When prescribed for frequent/planned replacement wear, the lens may be cleaned and disinfected using a chemical (not heat) lens care system.

The AQUASOFT (ocufilcon D) Soft (hydrophilic) Contact Lens is available as a single vision spherical lens, aspherical multifocal lens and as a back surface astigmatic (toric) lens. The hydrophilic nature of this material allows the lens to become soft and pliable when immersed in an aqueous solution. The ionic lens material. (ocufilcon D) is a co-polymer of 2-Hydroxyethylmethacrylate (2-HEMA) and Methacrylic Acid, cross-linked with ethylene glycol dimethacrylate (EGDMA), plus an initiator. The co-polymer consists of 45% ocufilcon D and 55% water by weight when immersed in normal buffered saline solution. The lens polymer contains a UV absorbing compound and is available clear or with a blue visibility-handling tint, color additive 'Reactive Blue 19', 21 CFR part 73.2121. The ocufilcon D name has been adopted by the United States Adopted Names Council (USAN). In the AQUASOFT Contact Lens with UV Blocker, a Benzophenone UV absorbing monomer is used to block UV radiation. The UV blocking for AQUASOFT averages > 99% in the UVB range of 280nm -315nm and 83% in the UVA range of 316 - 380mm. In the hydrated state, the lens conforms to the curvature of the eye 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 and appear somewhat warped however, it will return to its proper configuration when completely rehydrated in the proper storage solution.
