This device provides for a solid state camera system and light source onto an extraocular lens for real-time monitoring of cranial nerve pathways on anesthetized patients.


Intraoperative neurophysiologic monitoring provides the surgical team real-time feedback during surgeries that involve the brain, spinal cord, or peripheral nervous system. This allows for prompt interventions intraoperatively that has shown to reduce post-surgical incidence of paralysis, muscle weakness, sensory deficits, hearing loss, as well as other new neurologic deficits.


  • This device offers instantaneous intraoperative feedback concerning manipulations of the optic and oculomotor nerves, as well as the brain stems
  • Allows surgeons to make immediate corrective actions, preventing permanent deficits, and improving patient safety and surgical outcomes.
  • The device provides real-time monitoring of the 2nd and 3rd cranial nerve pathways for anesthetized patients.


  • Significant utility as an intraoperative neurophysiological monitoring device
  • Significant opportunity for clinical application in the marketplace
  • This technology may offer a significant improvement over existing IOM devices, leading to improved patient outcomes and surgical success.
