Study Details

This is an unblinded, parallel group randomized controlled trial to evaluate bright green light as an adjunct therapy after surgery at UPMC Shadyside. The primary outcome measure will be pain intensity with secondary outcome measures including opioid requirements, sleep quality, mood, and overall post-operative recovery. Specific aims/hypotheses for this study are as follows: Aim 1: To assess bright green light therapy's potential as a complementary post-operative analgesic strategy in patients recovering from surgery Hypothesis 1: Participants exposed to bright green light, in comparison to dim white (ambient) light, will have improved postoperative pain scores and lower opioid use. Aim 2: To examine the impact of bright green light therapy on patient-centered measures of post-operative recovery that may be related to improved circadian function. Hypothesis 2: Participants exposed to bright green light, in comparison to dim white (ambient) light, will have improved quality of post-operative recovery, enhanced sleep, and reduced anxiety and depression.
