The device description focuses on mechanical components and materials, and there is no mention of AI, ML, or related concepts.
No
A therapeutic device is used to treat or cure a disease or condition. This device is described as a surgical tool for initial lamellar resection of the cornea, which is an instrument used during a surgical procedure, not a device that provides therapy.
No
This device is a surgical keratome, used to make precise lamellar resections (cuts) in the cornea for surgical procedures. It is an instrument used during surgery, not for diagnosing a condition or disease.
No
The device description clearly outlines physical components made of plastic and stainless steel, including a keratome head, suction ring, handle, blade, and blade holder. It also mentions a power unit and sterilization, indicating a hardware-based device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for "initial lamellar resection of the cornea" during surgery. This is a surgical instrument used directly on a patient's tissue, not a device used to examine specimens derived from the human body to provide information for diagnosis, monitoring, or compatibility testing.
- Device Description: The description details a surgical keratome head, suction ring, blade, and handle. These are all components of a surgical tool.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue samples, etc.), reagents, or providing diagnostic information.
Therefore, this device falls under the category of a surgical instrument, not an In Vitro Diagnostic device.

Device Description
The ONE UP disposable keratome head and suction ring are identical in design, concept and principle to the predicate PLANCON microlamellar keratome single piece head K 970 377, the only difference being that the keratome head, the ring and the handle are made of high density plastic material.
The stainless steel blade and the plastic blade holder are similar to the blade and blade holder of the above predicate.
The keratome head has dovetails guides which engage in the dovetails of the suction ring.
The blade oscillates by means of the same turbine of the predicate device referred above.
The power unit is similar in characteristics, principles and functions to the power units of legally marketed keratomes.
The ONE UP disposable keratome head comes preassembled and presterilized in a copolyester sealed tray, sealed with TYVEK ® peel off cover. The sterilisation is performed under validated gamma radiation cycle with sterility assurance level of 10 ° and dosimetric release.
The plastic materials used for patient contact portion of device have been tested according to classification of USP and the grades used passes classes I through VI, and are deemed to be biocompatible.
System composition:
- Power unit
- Keratome head
- Keratome blade
- Nitrogen powered turbine
- Footswitches
- Applanator lenses
- Suction rings
The power unit includes pumps for producing vacuum.
The power unit has been designed to operate the keratome by means of 12 V DC motor or by means of nitrogen motor.
Only one of the above power options can be selected at the time by means of a 2 position switch in the front panel.
The front panel has several displays and features :
- Vacuum pressure gauge
- Gas pressure gauge
- Battery level indicator
- Battery charge indicator
- Connectors :
- Gas inlet
- Gas outlet
- Vacuum outlet
- Foot pedals
- Battery charger.
All connectors are of different type for preventing connecting mistakes.
The turbine motor is gas powered.
The recommended gas is nitrogen but the turbine will accept any medical gas. The turbine is not specific to this device.
The keratome head adapts to the turbine by means of a threaded part.
The keratome head includes the blade which is moved by the turbine.
Different heads are available in order to adjust the thickness of the cut.
The head is a single piece, thus no assembly or adjustment are necessary.
The suction rings are used to fixate and pressurize the eye and provide a base for the microkeratome. High precision dovetails ensure accurate cut depth and translation accross the cornea.

- · Vacuum outlet,
- · Foot pedals,
- · Battery charger.
All connectors are of different type for preventing connecting mistakes.
b2) Turbine
The turbine motor is gas powered.
The recommended gas is nitrogen but the turbine will accept any medical gas. The turbine is not specific to this device. It is already used in the U.S. in particular for dental use. It has been in the market for seven years.
b3) Keratome head
The keratome head adapts to the turbine by means of a threaded part.
The keratome head includes the blade which is moved by the turbine.
Different heads are available in order to adjust the thickness of the cut.
The head is a single piece, thus no assembly or adjustment are necessary. This is a major improvement which avoids the risk of uncorrect assembly and results in a much safer procedure.
- Suction rings b4)
The suction rings are used to fixate and pressurize the eye and provide a base for the microkeratome. High precision dovetails ensure accurate cut depth and translation accross the cornea.

Dear Mr. Duprat:
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 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). 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.
