The 510(k) summary describes a physical contact lens with specific material properties and dimensions. There is no mention of software, algorithms, or any computational components that would suggest the use of AI or ML.
Yes
The device is a contact lens indicated for the correction of refractive ametropia (myopia and hyperopia), presbyopia, and astigmatism, which are conditions affecting vision. Its purpose is to correct these physical conditions in the eye, aligning with the definition of a therapeutic device.
No
Explanation: The device is a contact lens used for correction of refractive ametropia, presbyopia, and astigmatism. It is a treatment device, not a diagnostic one.
No
The device description clearly describes a physical contact lens made of a specific material with defined dimensions and physical/optical properties. It is a tangible medical device, 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 C-Vue's Toric Multifocal Contact Lens is a medical device that is placed directly on the eye to correct vision. It does not analyze any biological samples.
- The intended use is for vision correction. The description clearly states the lens is for correcting refractive errors, presbyopia, and astigmatism. This is a therapeutic and corrective function, not a diagnostic one.
- The device description focuses on the physical properties of the lens. The details provided are about the material, dimensions, and optical properties of the contact lens itself, not about any reagents, instruments, or software used to analyze biological samples.
Therefore, based on the provided information, the C-Vue's Toric Multifocal Contact Lens is a medical device for vision correction, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The C-Vue's Toric Multifocal Contact Lens is indicated for daily wear for the correction of refractive ametropia (myopia and hyperopia), presbyopia and astigmatism up to 4.00 diopters in aphakic and/or not-aphakic persons with non-diseased eyes.
Eyecare practitioners may prescribe the lens for daily wear in a Planned Replacement Program. The lens may be disinfected using a chemical disinfection system.

Device Description
The C-Vue's Tonc (methafilcon A) Soft (hydrophilic) Multifocal Contact Lens is a front surface asphere consisting of multiple aspheric zones with an eccentric lenticulation for ballast and axis stabilization. The base curve has a toroidal posterior optic zone and a flattened peripheral curve which approximates the curvature of the sclera. The most plus power is in the center of the lens, with the power progressively becoming more minus towards the periphery. The lens material, (methafilcon A), is a copolymer of 2-hydroxyethyl methacrylate and methacrylic acid, crosslinked with ethyleneglycol dimethacrylate.
The C-Vue35 Toric Multifocal Contact Lens is a hemispherical shell of the following dimensions:
| Chord diameters | 14.0 to 15.0mm |
|---|---|
| Center thickness | 0.10 to 0.60mm; varies with power |
| Base curves | 8.4 to 9.3mm |
| Powers | -20.00 to +20.00 diopters |
| Add powers | Up to +3.00 diopters |
| Cylinder | Up to 4.00 diopters |
| Axis | 1° to 180° in 1° steps |
| Optical zone diameters | 5.0 to 10.0mm |
The physical/optical properties of the lens are:
| specific gravity | 1.09 |
|---|---|
| refractive index (wet) | 1.415 |
| light transmittance (clear and tint) | greater than 90% in the visible light region |
| water content | 55% |
| oxygen transmissibility | $18.83 \times 10^{-11}$ (cm²/sec)(ml O2/ml x mm Hg)* |
- as measured by Schema Versatae Model 920 connected to a polargraphic cell

(a)
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)
Classification. (1) Class II if the device is intended for daily wear only.(2) Class III if the device is intended for extended wear.

Dear Ms. Bruno:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
