What this Trial Is About
Researchers are evaluating the effects of binaural beats on patient satisfaction and comfort during cataract surgery in patients aged 65 years and older. This study involves patients undergoing phacoemulsification and posterior chamber intraocular lens implantation under monitored anesthesia care with propofol. The goal is to compare the impact of binaural beat auditory stimulation with no sound on satisfaction and intraoperative comfort in geriatric patients. Participants are randomly assigned to one of two groups. The experimental group wears earphones and listens to binaural beats continuously from arrival in the operating room until the surgery ends. The control group wears identical earphones but receives no auditory stimulus. Both groups receive monitored anesthesia care with propofol administered via target-controlled infusion at a set concentration during the procedure. Throughout surgery, vital signs and brain activity (bispectral index) are continuously monitored. After surgery, patient satisfaction is measured using a 7-point Likert scale. Secondary assessments include anesthesia method preference, intraoperative pain, sedation, anxiety levels, and quality of life measured by visual analogue scales. Any surgery-related discomfort or adverse events are recorded and compared. The study follow-up occurs immediately after surgery in the recovery room.
