Intended Use
The VisiJet Hydrokeratome is intended for use in performing anterior lamellar circular corneal resections. The VisiJet Hydrokeratome is indicated for use in patients undergoing surgery or other treatment requiring initial lamellar resection of the cornea.
Device Description
The VisiJet Hydrokeratome - Model 50 is a non-oscillating, non-mechanical microkeratome which utilizes a continuous high-velocity beam of sterile water for injection to effect a lamellar resection of the cornea. The major elements of this microkeratome are a system console, a footswitch and a handpiece with interchangeable suction rings. The operating principle of the water beam microkeratome is based on the ability to create high levels of static hydraulic pressure that is directed across the cornea, effecting a lamellar resection.

Not Found

No
The device description focuses on a mechanical process using a water beam and does not mention any AI/ML components or image processing.

Yes
The device is described as performing surgical resections to the cornea, which is a therapeutic intervention.

No
The device is described as a surgical tool for performing corneal resections, not for diagnosing conditions.

No

The device description explicitly states that the VisiJet Hydrokeratome includes a system console, footswitch, and handpiece with interchangeable suction rings, which are hardware components.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
  • VisiJet Hydrokeratome Function: The VisiJet Hydrokeratome is a surgical device used to perform a physical procedure (lamellar resection) directly on the cornea of a patient. It does not analyze specimens taken from the body.

The device description clearly outlines a surgical tool that uses a water beam to cut tissue, which is a direct intervention on the patient, not an in vitro test.

N/A

Intended Use / Indications for Use

The VisiJet Hydrokeratome is indicated for use in patients undergoing surgery or other treatment requiring initial lamellar resection of the cornea.

Summary of Performance Studies

The VisiJet™ Hydrokeratome™ has been designed and will be tested to applicable safety standards. All components in contact with tissue are manufactured from known biocompatible material. All motors are UL approved. The specifications and intended use of the VisiJet Hydrokeratome are the same or very similar to predicate devices. In addition, the VisiJet Hydrokeratome was found to perform equivalently to the predicate devices, the Baron Microkeratome System, Automatic Corneal Shaper (ACS) and the Medjet Hydrobrush, and as intended in all cases. Therefore, the technological differences between the VisiJet Hydrokeratome and the predicated devices do not raise any new issues of safety, effectiveness, or performance of the product.
