No
The document describes standard contact lenses and their material properties, with no mention of AI or ML in the intended use, device description, or performance studies.
Yes
The "Hyper-CL™ (hioxifilcon D) Therapeutic soft contact lenses for daily wear" are explicitly indicated for therapeutic use to promote corneal healing and relieve corneal pain by protecting the treatment of acute or chronic pathologies.
No
The device is a contact lens intended for vision correction, not for diagnosis. Its purpose is to correct refractive errors (myopia, hyperopia, astigmatism, presbyopia) and, in some cases, provide therapeutic support for corneal healing, rather than to identify or characterize a disease or condition.
No
The device description clearly states that the device is a physical contact lens made from a specific material (hioxifilcon D). It describes the physical properties and manufacturing process of the lens, which is a hardware component.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use of these contact lenses is for the correction of visual acuity and therapeutic use to promote corneal healing and relieve pain. These are physical and optical functions, not diagnostic tests performed in vitro (outside the body) on biological specimens.
- Device Description: The description details the material composition and physical properties of the contact lenses. It does not describe any components or processes related to analyzing biological samples for diagnostic purposes.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological specimens (blood, urine, tissue, etc.)
- Detecting or measuring specific substances (analytes)
- Providing information for the diagnosis, monitoring, or prognosis of a disease or condition based on in vitro analysis.
The device is a medical device, specifically a contact lens, used for vision correction and therapeutic purposes applied in vivo (on the body).

Device Description
The EyeYon (hioxifilcon D) Soft (hydrophilic) Contact Lenses & Hyper-CL™ (hioxifilcon D) Therapeutic Soft (hydrophilic) Contact Lenses for Daily Wear are fabricated from hioxifilcon D, which in the dry (unhydrated) state may be machined and polished. The hydrophilic nature of this material allows the lens to become soft and pliable when immersed in an aqueous solution. The EyeYon (hioxifilcon D) Soft (hydrophilic) Contact Lenses & Hyper-CL™ (hioxifilcon D) Therapeutic Soft (hydrophilic) Contact Lenses are manufactured from CONTAFLEX 54 optical blanks, supplied by Contamac Ltd (cleared under K150590).
The non-ionic lens material, (hioxifilcon D) is a co-polymer of 2-Hydroxyethylmethacrylate (2-HEMA) and 2,3- Dihydroxypropyl Methacrylate (Glycerol Methacrylate), cross-linked with ethylene glycol dimethacrylate (EGDMA), plus an initiator. The co-polymer consists of 46% hioxifilcon D and 54% water by weight when immersed in normal buffered saline solution. The hioxifilcon D name has been adopted by the United States Adopted Names Council (USAN).
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 (hioxifilcon D) 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.
The Hyper-CL™ (hioxifilcon D) Therapeutic Soft (hydrophilic) Contact Lens design includes two (2) different base curves, and a peripheral groove including 4-16 fenestrations. When worn on the eve the Hyper-CL™ lens design creates a tear film reservoir between the corneal surface and the back surface of the contact lens. The fenestrations improve tear mixing efficiency.
The hydrophilic characteristics allow aqueous solutions to enter the lens and in its fully hydrated state the lens is approximately 54% water by weight. The physical properties of the EyeYon & Hyper-CLTM (hioxifilcon D) Soft (hydrophilic) Contact Lenses are:
Refractive Index: 1.5193 (hydrated)
Light Transmission: greater than 96%
Water Content: 54% ± 2%
Specific Gravity (wet): 1.120
Oxygen Permeability: 20.96 X 10-11 (cm2/sec) (ml O2/ml x mm Hg @ 35°C), (revised Fatt method).
The EyeYon (hioxifilcon D) Soft (hydrophilic) Contact Lenses & Hyper-CL™ (hioxifilcon D) Therapeutic Soft (hydrophilic) Contact Lenses are available in the following parameter ranges:
• Diameter: 10.0 mm to 17.0 mm
• Base Curve: 6.0 mm to 10.0 mm
• Center Thickness: varies (0.12 mm at +3.00 D)
• Powers: -20.00 D to +20.00 D (0.25 D steps)
o Toric: up to -4.00 D (0.50 D steps)
o Multifocal: up to +3.00 D
