The document describes a standard contact lens and its material properties, with no mention of AI or ML technology.
No.
The contact lens is indicated for the correction of refractive ametropia (myopia and hyperopia) and astigmatism, which are refractive errors, not diseases. It functions as a vision correction device rather than a therapeutic treatment for a medical condition.
No
This device is a contact lens intended for correcting refractive ametropia (myopia and hyperopia) and astigmatism, not for diagnosing medical conditions.
No
The device description clearly states it is a physical contact lens made of a hydrophilic polymer, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVDs are used to examine specimens from the human body. The provided text describes a contact lens, which is a medical device placed on the surface of the eye. It does not involve the analysis of biological samples like blood, urine, or tissue.
- The intended use is for correcting vision. The primary function of this device is to correct refractive errors (myopia, hyperopia, astigmatism) by altering the way light enters the eye. This is a therapeutic or corrective function, not a diagnostic one.
- The device description focuses on the physical and chemical properties of the lens material. This is typical for a medical device intended for direct contact with the body, not for a diagnostic test.
The information provided clearly indicates that this is a contact lens used for vision correction, which falls under the category of medical devices, but not In Vitro Diagnostics.

Intended Use / Indications for Use
The Sauflon 55 UV (methafilcon) Soft (Hydrophilic) Visibility Tinted Contact Lens is indicated for daily wear for the correction of the refractive ametropia (myopia and hyperopia) and astigmatism in aphakic and not-aphakic persons with non-diseased eyes that may exhibit astigmatism up to 2.00 Dioptres that does not interfere with visual acuity.
Eyecare practitioners may prescribe the lens for daily wear in Frequent Replacement Program. The lenses may be disinfected using chemical or hydrogen peroxide disinfection systems.

Device Description
The SAUFLON 55UV (methafilcon A) Soft (Hydrophilic) Visibility Tinted Contact Lenses for Daily Wear is available as a single vision lens in an aquamarine visibility tint. The lens material (methafilcon A) is a hydrophilic polymer of 2-hydroxyethyl methacrylate (HEMA) and methacrylic acid, which is cross-linked with ethyleneglycol dimethacrylate. When hydrated the Inns consists of 45.0% HEMA and 55.0% water by weight of saline immersed in normal saline. The lens is visibility tinted aqua with: Reactive Blue No. 4 and Reactive Yellow Dye # 86. A benzophenone UV absorbing monomer is used to block UV radiation.
The average transmittance characteristics are less than 10% in the UVB range of 280 to 315nm and less than 40% in the UVA range of 315-380mm.
The SAUFLON 55 UV Contact Lens is a hemispherical flexible shell, which covers the cornea and a portion of the adjacent sclera, with the following dimensions:
Chord Diameter: 14.0mm to 15.0mm
Centre Thickness: 0.03mm to 0.40mm
Base Curve: 8.40mm to 9.30mm
Powers: -20.00 Diopters to +20.00Diopters
The physical/optical properties of the lens are:
Refractive Index: 1.40

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The results of toxicology testing (cytotoxicity, acute systemic toxicity and acute ocular irritation) show the lenses to be non-toxic and non-irritating. Furthermore, the results of residual monomer and colour leachability testing demonstrate that the respective extracts did not contain significant levels of leachable colour or residual monomers.
The physical optical, and chemical properties of the Sauflon 55 UV (methafilcon A) Soft Hydrophilic Visibility Tinted Contact Lens for Daily Wear are equivalent to those of the FREOUENCY 55 (methafilcon A) Hydrophilic Contact lenses for Daily Wear (clear and tinted).

Identification. A soft (hydrophilic) contact lens is a device intended to be worn directly against the cornea and adjacent limbal and scleral areas of the eye to correct vision conditions or act as a therapeutic bandage. The device is made of various polymer materials the main polymer molecules of which absorb or attract a certain volume (percentage) of water.(b)
