The document describes a standard contact lens with no mention of AI or ML technology in its design, manufacturing, or intended use.
No
Therapeutic devices are generally used to treat or prevent a disease or condition. This device is indicated for the optical correction of refractive ametropia (myopia and hyperopia) and/or presbyopia, which are vision impairments, not diseases requiring therapeutic intervention.
No
Explanation: This device is a contact lens intended for optical correction of vision, not for diagnosing medical conditions.
No
The device is a contact lens, which is a physical medical device made of hydrogel and polymer materials. The description details its composition, manufacturing process, and physical properties, indicating it is not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The described device is a contact lens. Its intended use is for the optical correction of refractive errors (myopia, hyperopia, astigmatism, presbyopia) by being placed directly on the surface of the eye.
- Lack of Biological Sample Analysis: The device does not analyze any biological samples from the patient. It is a physical device that alters the path of light entering the eye.
Therefore, the Tangible Hydrogel with Tangible Polymer (etafilcon A) Soft (Hydrophilic) Daily Disposable Contact Lens falls under the category of a medical device, but not specifically an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The Tangible Hydrogel with Tangible Polymer (etafilcon A) ASPHERIC Soft (Hydrophilic) Daily Disposable Contact Lens is indicated for the optical correction of refractive ametropia (myopia and hyperopia) in phakic persons with non-diseased eyes who may have 1.00 D or less of astigmatism.
The Tangible Hydrogel with Tangible Polymer (etafilcon A) TORIC Soft (Hydrophilic) Daily Disposable Contact Lens is indicated for the optical correction of refractive ametropia (myopia and hyperopia) in phakic persons with nondiseased eyes who may have 5.00 D or less of astigmatism.
The Tangible Hydrogel with Tangible Polymer (etafilcon A) MULTIFOCAL Soft (Hydrophilic) Daily Disposable Contact Lens is indicated for daily wear for the optical correction of refractive ametropia (myopia and hyperopia) and/or presbyopia in phakic or aphakic persons with non-diseased eyes who may need up to 2.50 D of ADD power and may have 1.00 D or less of astigmatism.
Eye care professionals may prescribe the lenses for daily disposable wear. Lenses shall be discarded upon removal.

Device Description
The Tangible Hydrogel with Tangible Polymer (etafilcon A) Soft (Hydrophilic) Daily Disposable Contact Lens is available in an aspheric design and manufactured using the castmolding process. The lenses consist of 58% water and 42% etafilcon A. The lens material is a random copolymer composed of 2-hydroxyethyl methacrylate (HEMA) and methacrylic acid (MAA), which are cross-linked with Trimethylolpropane trimethacrylate (TMPTMA) and Ethylene Glycol Dimethacrylate (EGDMA) via UV photo-polymerization.
The Tangible Hydrogel with Tangible Polymer (etafilcon A) Soft (Hydrophilic) Daily Disposable Contact Lenses are available in a light blue tint ([Phthalocvaninato(2-)]copper) for visibility and handling. The lenses also contain a Benzotriazole ultraviolet (UV) absorbing monomer to block UV radiation. The average transmittance characteristics are less than 5% in the UVB range (280 to 315 nm), and less than 30% in the UVA range (316 to 380nm).
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 (etafilcon A) soft hydrophilic contact lens has an aspheric 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 appear somewhat warped; however, it will return to its proper configuration when completely rehydrated in the proper storage solution.
The lenses are supplied sterile in blister packages containing a buffered saline solution. Package 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.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical Testing: A series of in vitro and in vivo preclinical toxicology and biocompatibility tests were performed to assess the safety and effectiveness of the Tangible Hydrogel with Tangible Polymer (etafilcon A) Soft (Hydrophilic) Daily Disposable Contact Lenses packaged in blister packaging. All non-clinical toxicology tests were conducted in accordance with the GLP regulation. All other testing was conducted according to valid scientific protocols.
Key results:
- Lenses supplied in blister packages are sterile for the indicated shelf-life.
- The finished lenses, packaging material and extracts are non-toxic and non-irritating, and
- Lens physical and material properties are consistent with currently marketed lenses.
Clinical Testing: The safety and effectiveness of finished contact lenses manufactured from the etafilcon A material have been established previously through clinical performance testing.
