Plain-language summary
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.

Inclusion Criteria:
* Age \>/= 18 years
* Planned to undergo laparoscopic or robotic surgery at UPMC Shadyside Hospital
* Anticipated post-operative length of stay \>/= 48 hours
* Able to speak and read English fluently, with the capacity to provide informed consent and complete the associated surveys independently
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
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
