No
The document describes a physical contact lens with a specific design and material properties. There is no mention of software, algorithms, or data processing that would indicate the use of AI or ML.
No
The device is a contact lens designed to correct refractive errors and manage keratoconus, which is a structural correction rather than a therapeutic treatment.
No
This device is a contact lens designed for vision correction and keratoconus management, not for diagnosing medical conditions.
No
The device description clearly states it is a rigid gas permeable contact lens fabricated from a material, which is a physical hardware component.
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 ComfortKone™ Keratoconus Aspheric Contact Lens is a medical device that is placed on the human cornea. Its function is to act as a refracting medium to correct vision and manage keratoconus. It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states it's for "daily wear for persons requiring Keratoconus management" and "correction of refractive ametropia." This is a therapeutic and corrective function, not a diagnostic one.
Therefore, the ComfortKone™ Keratoconus Aspheric Contact Lens is a medical device, specifically a contact lens, but it does not fit the definition of an In Vitro Diagnostic.

Intended Use / Indications for Use
The Comforthone™ Keratoconus Aspheric (patlufocon C) Rigid Gas Permeable (RGP) Daily Wear Contact Lens (Clear and Tinted, Lathe-cut from Lens Blank) is indicated for daily wear for persons requiring Keratoconus management with otherwise non-diseased eyes. The lens may be prescribed for the correction of refractive ametropia (myopia, hyperopia and astigmatism) in aphakic and not-aphakic persons. The lens may be disinfected with a chemical disinfection system.

Device Description
The Comfort Kone" Keratoconus Aspheric Contact Lens is fabricated from the hydrophobic contact lens material (patfufocon C). The material is a thermoset copolymer derived from fluorosilicone acrylate When placed on the human cornea, the ComfortKone" Keratoconus Aspheric rigid gas monomer. permeable contact lenses act as a refracting medium to focus light rays upon the retina.
The ComfortKone" is a aspheric contact lens. It is designed to provide optimum comfort and visual acury to the keratoconus patient. The ComfortKone" lens design begins with a spherical 4,0 mm optic zone that fits the peak of the cone and provides for good visual acuity. The lens then the aspheric curve, which is considered the fitting curve of the lens. The aspheric curve will vary in rate of change depending on how far the keratoconus has advanced and creates optimal corneal alignment. The design finishes with two junctionless peripheral aspheric curves to maintain alignment.
The physical properties of the lens are
Refractive Index: 1.475 (Nd at 25°C)
Light Transmission (clear): 93 %
Light Transmission (blue): 91 %
Light Transmission (gray): 91 %
Light Transmission (green): 92 %
Wetting Angle (receding angle): 12.8°
Specific Gravity: 1.14

§ 886.5916 Rigid gas permeable contact lens.
(a)
Identification. A rigid gas permeable contact lens is a device intended to be worn directly against the cornea of the eye to correct vision conditions. The device is made of various materials, such as cellulose acetate butyrate, polyacrylate-silicone, or silicone elastomers, whose main polymer molecules generally do not absorb or attract water.(b)
Classification. (1) Class II if the device is intended for daily wear only.(2) Class III if the device is intended for extended wear.
(c)
Date PMA or notice of completion of a PDP is required. As of May 28, 1976, an approval under section 515 of the act is required before a device described in paragraph (b)(2) of this section may be commercially distributed. See § 886.3.
