Patient Satisfaction and Recovery Outcomes Associated With Perioperative ELIXIR MD Use

The goal of this observational registry study is to characterize postoperative recovery outcomes in adult patients receiving standard-of-care perioperative light therapy using an FDA-cleared photobiomodulation device as part of routine clinical practice. The study aims to describe changes in patient-reported and clinician-assessed recovery measures following elective surgical procedures. The main questions this registry aims to answer are: 1. How do patient-reported recovery outcomes, including pain, satisfaction, and perceived improvement, change over the postoperative period? 2. How do clinician-assessed indicators of recovery, such as swelling and bruising, change over time following surgery? This study does not include a randomized comparison group. Outcomes will be described longitudinally within participants based on data collected during routine care. Participants will: 1. Receive perioperative light therapy as part of standard clinical care, per their treating clinician 2. Complete patient-reported outcome questionnaires at defined postoperative time points 3. Undergo standardized clinical photography and routine clinical assessments as part of usual follow-up
