It is a single-use probe for the intraoperative guidance, detection, identification, and confirmation of parathyroid glands during thyroidectomies, parathyroidectomies, and lymph node dissections.

The PTeye system is an intraoperative technology system that uses NIR autofluorescence to guide, detect, identify and confirm the parathyroid glands. Autofluorescence (AF) is a phenomenon where there is light emission in the visible UV-NIR spectrum when biological substrates are excited by light of a specific wavelength.
