Eye Movements to Predict Post-Operative Delirium

Postoperative delirium (POD) is a common complication in older adults undergoing surgery, lacking objective and noninvasive diagnostic methods. This trial aims to evaluate the feasibility and prognostic performance of Eye movements (EM) as a risk biomarker for the development of POD in older patients undergoing moderate- to high-risk surgery. The investigators hypothesize that EM tracking will accurately predict POD, potentially optimizing early intervention and patient outcomes.
