Assessing the Efficacy of Intranasal Neurostimulation in Ameliorating Symptoms of Neuropathic Corneal Pain 

Patients that suffered from neuropathic pain or photoallodynia, reported immediate relief of pain after use of TrueTear® intranasal neurostimulator (ITN). We propose a pilot study for treatment of neuropathic corneal pain (NCP) with ITN with the following specific aims: 

  • To elucidate the efficacy of ITN in ameliorating pain among neuropathic corneal patients.
  • To elucidate the safety, efficacy, longevity of ITN in ameliorating pain among neuropathic corneal patients during a 90-day period with daily use.
  • o assess quality of life changes by treating neuropathic corneal pain with ITN during a 90-day period with daily use.
