Summary

This study looks at whether playing binaural beats (a type of sound) through earphones during cataract surgery can help older patients feel more satisfied and comfortable. About 60 people aged 65 and older will take part, with half listening to the sounds and half wearing earphones without sound. Researchers will measure satisfaction, pain, anxiety, and any side effects.
