Run by Seoul National University Hospital · NCT07609186 · Data updated 2026-11-12
This study tests whether listening to binaural beats during cataract surgery helps patients aged 65 and older feel more comfortable and satisfied with the procedure.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 65 and older scheduled for their first phacoemulsification with posterior chamber IOL under MAC who can understand the study and consent.
✕Probably not a fit
Patients with hearing impairment, those unable to wear earphones, or those not perceiving auditory stimuli may not benefit.

What this trial studies
In this randomized, controlled study, patients 65 years and older undergoing first-time phacoemulsification with posterior chamber intraocular lens implantation under monitored anesthesia care are assigned to either a binaural beat group or a sham control group. The binaural beat group wears earphones and listens to binaural beats from arrival in the operating room until the procedure ends; the control group wears identical earphones but receives no auditory stimulus. Continuous monitoring includes vital signs and BIS, with postoperative assessment of overall satisfaction on a 7-point scale and secondary measures such as anesthesia method preference, intraoperative pain, and sedation. The trial aims to determine if binaural beats can improve intraoperative comfort and patient-perceived experience.
Why it matters
Potential benefit: If successful, binaural beats could improve comfort and satisfaction for older adults during cataract surgery.
How similar studies have gone: Previous research in other settings has explored binaural beats for anxiety and comfort, with mixed but promising results in perioperative care.
