Sphere/ Asphere

Pegavision (Toufilcon B) Daily Disposable Soft (Hydrophilic) Contact Lenses and Pegavision (Toufilcon B) Soft (Hydrophilic) Contact Lenses are indicated for daily wear for vision correction of refractive ametropia (myopia or hyperopia) in aphakic or non-aphakic persons with non-diseased eyes. The lenses may be worn by person who exhibit refractive astigmatism of 2.00 diopters (D) or less where the astigmatism does not interfere with visual acuity. The lens may be prescribed in spherical powers ranging from +6.00D to -12.00D.

Toric

Pegavision (Toufilcon B) Daily Disposable Soft (Hydrophilic) Contact Lenses and Pegavision (Toufilcon B) Soft (Hydrophilic) Contact Lenses with Toric designs are indicated for daily wear for vision correction of refractive ametropia (myopia or hyperopia with astigmatism) in aphakic or non-aphakic persons with non-diseased eyes. The lens may be prescribed in spherical powers ranging from +6.00D to -12.00D and astigmatic corrections from -0.25D to -3.50D.

Multifocal

Pegavision (Toufilcon B) Daily Disposable Soft (Hydrophilic) Contact Lenses and Pegavision (Toufilcon B) Soft (Hydrophilic) Contact Lenses with Multifocal designs are indicated for daily wear for the correction of refractive ametropia (myopia and hyperopia), and/or presbyopia in aphakic and/or non-aphakic persons with non-diseased eyes in powers from +6.00 to -12.25 diopters and with non-diseased eyes who may require a reading addition of +0.25D to +3.00D. The lenses may be worn by persons who exhibit astigmatism of 2.00 diopters or less that does not interfere with visual acuity.

Pegavision (Toufilcon B) Daily Disposable Soft (Hydrophilic) Contact Lenses are intended for single-use disposable wear.

Pegavision (Toufilcon B) Soft (Hydrophilic) Contact Lenses are intended for frequent/planned replacement wear with cleaning, rinsing, disinfecting and scheduled replacement as prescribed by the eye care professional. When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical (not heat) lens care system only.

Pegavision (Toufilcon B) Daily Disposable Soft (Hydrophilic) Contact Lenses and Pegavision (Toufilcon B) Soft (Hydrophilic) Contact Lenses are clear or visibility tinted, incorporate a UV blocker, and are available in spherical, aspherical, toric, and multifocal designs. The lens material, Toufilcon B is a co-polymer of 2-Hydroxyethylmethacrylate (2-HEMA), N-Vinyl-2-Pyrrolidinone (NVP), N,N-Dimethylcarylamide (DMA), Methacrylic Acid (MAA), (3-Methacryloxy-2-hydroxypropoxy)propylbis(trimethylsiloxy)methylsilane (SiGMA) and Polydimethylsiloxane macromer (monofunctional Polydimethylsiloxane) (PDMS macromer), cross-linked with Ethylene glycol dimethacrylate (EGDMA) and Triallyl isocyanurate (TAIC) via photopolymerization. The copolymer consists of 50% Toufilcon B and 50% water by weight when immersed in a borate-buffered saline solution. There are two types of buffer solutions: one contains Tween 80, Polyethylene Glycol, and Sodium Hyaluronate; the other contains the same components with the addition of Cyanocobalamin. The visibility tinted lens is tinted with Reactive Blue 19, 21 CFR 73.3121. A benzotriazole UV absorbing monomer is used to block UV radiation. The UV blocking averages 95% in the UVB range of 280 nm to 315 nm and 50% in the UVA range of 315 nm to 380 nm. The Toufilcon B name has been adopted by the United States Adopted Names Council (USAN).
