Stopped: PI is leaving institution. USF will likely resume study activity but TMC is no longer conitinuing study activity.
This study is designed to learn more about the impact different types of stimuli, such as heat, cold and vibration, can have on ocular pain response. This is called quantitative sensory testing (QST). Most procedures being performed in this study, except the QST, are standard of care which means they are performed during the participant's routine eye examination.
