Overview

Brief Summary

In this study the investigators aim to examine the effects of Transcranial Direct Current Stimulation (tDCS) on pain levels as well as the changes in cognitive (thought) processing in individuals with chronic pain of the cornea -- and also compared with healthy controls.

Outcomes

Primary Outcomes

Changes in pain scales

Time Frame: Measured for approximately 2 weeks

We will measure changes in the visual analogue scale (VAS) for pain, and also measure pain threshold (using an algometer) before and after each stimulation session. We will compare the measurements from before stimulation to after stimulation, in each scheduled session, as this study is measuring the effects of a single session of tDCS.
