The summary describes a contact lens with a specific physical design and material composition, with no mention of AI or ML in its function or manufacturing process.
No.
Explanation: The device is a contact lens used for vision correction (refractive ametropia, presbyopia), which is not considered a therapeutic function. Therapeutic devices are typically used to treat or prevent a disease or condition, whereas this device corrects a refractive error.
No
Explanation: The device is a contact lens intended for correcting refractive ametropia (myopia, hyperopia, and/or presbyopia). Its function is to correct vision, not to diagnose a medical condition.
No
The device description clearly describes a physical contact lens made of a specific material with defined dimensions and properties, indicating it is a hardware device.
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 description clearly states that this device is a contact lens intended for correcting refractive errors (myopia, hyperopia, presbyopia) in the eye. It is a physical device worn on the surface of the eye.
- Lack of Diagnostic Testing: There is no mention of this device performing any kind of test on a biological sample or providing diagnostic information about a patient's health status. Its function is purely corrective for vision.
Therefore, the ESSTECH® MULTI Aspheric Contact Lens falls under the category of a medical device, but not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The ESSTECH® MULTI Aspheric (multifocal) (hioxifilcon B) Soft (hydrophilic) Contact Lens is indicated for daily wear for the correction of refractive ametropia (myopia, hyperopia and/or presbyopia) in not-aphakic persons with non-diseased eyes. The lens may be worn by persons who may exhibit astigmatism of 1.50 diopters or less that does not interfere with visual acuity.
The lens may be disinfected using either heat (thermal) or chemical (not heat) disinfection systems.

Device Description
The ESSTECH® MULTI Aspheric (multifocal) (hioxifilcon B) Soft (hydrophilic) Contact Lens is available as a lens with an aspheric front surface for the correction of visual acuity in presbyopic persons who are myopic or hyperopic. The lens is constructed to provide optimum edge thickness and contour, with the central area providing the reading power in the equivalent of a 2.00 diopter near addition. The aspheric front curve undergoes a progressive power change, resulting in intermediate and distance power outward from the center. The lens is a flexible transparent shell of the following dimensions:
The lens material, hioxifilcon B, is a hydrophilic co-polymer of glycerol methacrylate (GMA) and 2-hydroxyethyl methacrylate (2-Hema), crosslinked with ethylene glycol dimethacrylate. The lens is swollen to equilibrium state in sterile buffered saline solution, and contains 48% water by weight when fully hydrated.

§ 886.5925 Soft (hydrophilic) contact lens.
(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.
(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.

Dear Dr. Szabocsik:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations .
