What this trial is about
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.
Who can take part
Inclusion criteria
- Age \>/= 18 years
- Planned to undergo laparoscopic or robotic surgery at UPMC Shadyside Hospital

Exclusion criteria
- Pregnancy
- History of significant ocular issues/dysfunction (†‡ ) (e.g., glaucoma, ocular trauma, macular degeneration, cataracts) that would interfere with the ocular mechanism of action
- History of significant neurological disease (‡) (e.g., traumatic brain injury, stroke, neurodegenerative disease) that would compromise the reliability of pain screening and/or interfere with the central mechanism of action
- History of bipolar disorder or schizophrenia, which could increase the risk of an adverse reaction to light exposure (i.e., acute mania)
- History of splenectomy, which would interfere with the mechanism of action
- Ocular issues corrected with contact lenses or spectacle corrective eyeglasses will NOT be considered a criterion for exclusion ‡Unclear cases will be at the discretion of the PI
