First seen Jun 11, 2026 · Last updated Jun 23, 2026 · Updated 3 times
Summary
This pilot study tested whether a TENS device, which sends mild electrical pulses through the forehead, is safe and practical for treating chronic eye pain in veterans. Thirty-nine adults with persistent eye pain for at least six months used the device at home for up to 20 minutes per session over six months. The goal was to see if the device caused side effects and if people could use it correctly, paving the way for a larger trial.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
transcutaneous electrical nerve stimulation (TENS) device
What this could lead to
If this approach works, it could offer a non-drug, non-addictive option for managing chronic eye pain.
What could go wrong
This is a small pilot study with only 39 participants and no placebo group. The results only show safety and feasibility, not that TENS actually reduces pain.
