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. (efrofilcon A) is a daily wear silicone hydrogel contact lens that is not surface treated and characterized by a high water content. The lens material is composed of silicone monomers cross linked with other monomers and optionally incorporates D&C Green 6 as an integrated handling tint. The lenses are made by lathe-cut for custom RX. It consists of 26% efrofilcon A and 74% water by weight when immersed in a 0.9% saline solution. The (efrofilcon A) name has been adopted by the United States Adopted Names Council (USAN). 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 (efrofilcon A) soft hydrophilic contact lens has a spherical back 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. {2}------------------------------------------------ 510(k) Premarket Notification The Physical properties of the lens are: | Refractive Index | 1.38 | |---------------------|------------------------------------------------------------------------| | Light Transmission | greater than 97% | | Surface Character | hydrophilic | | Water Content | 74 % | | Specific Gravity | 1.048 (hydrated) | | Oxygen Permeability | 59.8 x 10-11 (cm2/sec) (ml O2/ml x hPa @ 35°C), (revised Fatt method). | The hydrophilic characteristics allow aqueous solutions to enter the lens and in its fully hydrated state the lens is approximately 74% water by weight. The lenses will be manufactured in spherical, aspherical, toric, multifocal toric and irregular cornea configurations with the following features and properties. | • Chord Diameter | 12.0 mm to 16.00 mm | |-------------------------------------|----------------------------------| | • Center Thickness | 0.01 mm to 0.50 mm | | • Base Curve | 8.0 mm to 9.5 mm | | • Power Range | -20.00D to +20.00D in 0.25 steps | | • Cylinder Power (Toric) | -0.25D to -12.00D | | • Cylinder Power (Multifocal Toric) | -0.25D to -4.00D | | • Add Power (Multifocal) | +0.50D to +4.00D | The lens is supplied sterile in vials containing a 0.9% saline solution. Vial labeling is printed with appropriate lot numbering, expiration dating and lens parameter identification. Expiration dating has been established based on studies of product stability, package integrity, and validation of the sterilization process. #### Intended Use: The AVT NATURASOFT, sphere (efrofilcon A) Silicone Hydrogel Soft Contact Lenses for daily wear are indicated for the correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons with non-diseased eyes. 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 AVT NATURASOFT, toric (efrofileon A) Silicone Hydrogel Soft Contact Lenses for daily wear are indicated for the correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons with non-diseased eyes and/or possesses refractive astigmatism not exceeding 12 diopters. The AVT NATURASOFT, multifocal (efrofilcon A) Silicone Hydrogel Soft Contact Lenses for daily wear are indicated for the correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons with non-diseased eyes and/or possesses refractive astigmatism not exceeding .75 diopters and are presbyopic requiring add power of up to +4.00 diopters. {3}------------------------------------------------ ## Advanced Vision Technologies 510(k) Premarket Notification The AVT NATURASOFT, multifocal toric (efrofilcon A) Silicone Hydrogel Soft Contact Lenses for daily wear are indicated for the correction of ametropia (myopia and hyperopia) in aphakic and nonaphakic persons with non-diseased eyes and/or possesses refractive astigmatism not exceeding 4 diopters and are presbyopic requiring add power of up to +4.00 diopters. The AVT NATURASOFT, irregular cornea (efrofilcon A) Silicone Hydrogel Soft Contact Lenses for daily wear are indicated for the correction of ametropia (myopia and hyperopia) in aphakic and nonaphakic persons and may be prescribed in otherwise non-diseased eyes that require a Soft Contact Lens for the management of irregular corneal conditions such as keratoconus and post graft fitting. 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 or hydrogen peroxide disinfection systems. #### Testing: Non-clinical Testing Non-clinical Testing A series of in vivo preclinical toxicology and biocompatibility tests were performed to assess the safety and effectiveness of the AVT NATURASOFT (efrofilcon A) Silicone Hydrogel Soft Contact Lenses packaged in glass vials. All non-clinical toxicology tests were conducted in accordance with the GLP regulation. All other testing was conducted according to valid scientific protocols. > Test results of the non-clinical testing on the AVT NATURASOFT (efrofilcon A) Silicone Hydrogel Soft Contact Lenses demonstrate that: - Lenses supplied in glass vials are sterile for the indicated shelf-life. - The packaging material and extracts are not toxic and not irritating, and ● - Lens physical and material properties are consistent with currently marketed . lenses. ### Clinical Data The clinical performance of the (efrofilcon A) lens material has been previously established, and therefore was not required for this 510(k). The AVT NATURASOFT, (efrofilcon A) Silicone Hydrogel Daily Wear Soft Contact Lens is identical to the cleared Intelliwave3 (efrofilcon A) Silicone Hydrogel Daily Wear Soft Contact Lens, cleared under K100221. The AVT NATURASOFT, (efrofilcon A) Silicone Hydrogel Daily Wear Soft Contact Lenses have the identical manufacturing process (lathe-cut versus lathecut) as the marketed Intelliwave3 (efrofilcon A) Silicone Hydrogel Daily Wear Soft Contact Lens, cleared under K100221.
