Caffeine to speed recovery after eye surgery in older adults
This study tests whether a small dose of caffeine placed under the tongue helps older adults wake up faster and feel less confused after eye surgery under general anesthesia. Researchers want to see if this simple approach can improve how quickly patients recover and reduce post-surgery agitation.
Summary written for real people, not researchers, by Clin2.

This trial tests giving either lidocaine or dexmedetomidine during abdominal surgery to see if it helps keep the brain healthy and lowers the chance of waking up confused or agitated. It is for older adults having planned abdominal surgery who are otherwise in fairly good health.
This trial is testing whether a melatonin tablet placed under the tongue before surgery can help older adults feel calmer and more comfortable during cataract surgery. Melatonin is a natural sleep hormone that may reduce anxiety without the side effects of common sedatives.
This study tests whether two doses of ketamine (a medicine given through a vein) can reduce a reflex that slows the heart during eye surgery. If you are having eye surgery that involves moving the eye muscles, you may be eligible.
This study compares different types of general anesthesia by checking how your pupils (the black part of the eye) respond after surgery. It may help doctors understand which anesthesia options are better for eye-related side effects after planned ear, nose, or throat operations.
This study uses eye-tracking technology to see if it can predict post-operative delirium in older adults after surgery. You will have your eye movements measured before and after surgery to help identify early signs of delirium.
This study explores how light exposure during and after anesthesia may affect your recovery, sleep quality, and comfort. Researchers want to understand if light timing can improve how you feel after surgery.
