Intended Use
The instrument is used for measuring the corneal thickness of the eye.
Device Description
The PachPen device is designed as an ultrasound pachymeter which uses pulsed echo ultrasound to measure the corneal thickness of the eye. It utilizes an eye-contact probe to generate and receive the ultrasound pulses, and provides a numeric display of returning pulse echoes to indicate the thickness of the cornea.
More Information

Not Found

No
The description details a standard ultrasound pachymeter using pulsed echo technology, with no mention of AI or ML algorithms for data processing or interpretation.

No
The device is used for measuring the corneal thickness, which is a diagnostic function, not a therapeutic one. It provides information about the eye's condition rather than treating it.

Yes

Explanation: The device measures corneal thickness, which is a physiological parameter used to diagnose conditions like glaucoma or corneal edema, fitting the definition of a diagnostic device.

No

The device description explicitly states it is an "ultrasound pachymeter" that "utilizes an eye-contact probe to generate and receive the ultrasound pulses," indicating it includes hardware components beyond just software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to measure the corneal thickness of the eye. This is a direct measurement of a physical characteristic of the eye, not an analysis of a biological sample (like blood, urine, or tissue) to diagnose a disease or condition.
  • Device Description: The device uses ultrasound to measure a physical dimension. It does not involve the use of reagents, calibrators, or controls typically associated with IVD tests.
  • Anatomical Site: The measurement is performed directly on the cornea of the eye, which is an in-vivo measurement, not an in-vitro analysis of a sample taken from the body.

IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for the diagnosis, monitoring, or treatment of diseases or conditions. This device performs a measurement on the body.

Intended Use / Indications for Use

The instrument is used for measuring the corneal thickness of the eye.
Intended Use: Diagnostic ultrasound imaging or fluid flow analysis of the human body as follows: Ophthalmic, A-mode (P=previously cleared by FDA).

§ 892.1560 Ultrasonic pulsed echo imaging system.

(a)
Identification. An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Dear Mr. Wright:

We have reviewed your Section 510(k) premarket notification of intent to market the device we nave reviewed your Booken or resped the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate for ass stated in the Merror, 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 Cosmone Act (110). "The general controls provisions of the Act include requirements for annual provision, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

This determination of substantial equivalence applies to the following transducers intended for use with the PachPen Pachymeter, as described in your premarket notification:

Transducer Model Number

A-mode 10.5 MHz

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 labeling (21 OF R Part 807), good mart 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This determination of substantial equivalence is granted on the condition that prior to shipping the first device, you submit a postclearance special report. This report should contain complete information, including acoustic output measurements based on production line devices, requested in nnonmation, meraling working works September 30, 1997 "Information for Manufacturers Seeking Appendix O; (enerobed) oversic Ultrasound Systems and Transducers." If the special report is incomplete or contains unacceptable values (e.g., acoustic output greater than approved levels), then the 510(k) clearance may not apply to the production units which as a result may be considered adulterated or misbranded.

The special report should reference the manufacturer's 510(k) number. It should be clearly and prominently marked "ADD-TO-FILE" and should be submitted in duplicate to:

Food and Drug Administration Center for Devices and Radiological Health Document Mail Center (HFZ-401) 9200 Corporate Boulevard Rockville, Maryland 20850

This letter will allow you to begin marketing your device as described in your premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus permits your device to proceed to market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html
