Brief summary
Binaural beat audio may decrease operative pain and anxiety in cataract surgery under numbing eyedrops. This study aims to evaluate the effects of binaural beat audio on pain and anxiety in patients undergoing cataract surgery under topical anaesthesia. The primary outcome is the difference in pain score and anxiety scores between the binaural beat audio and the control group. The secondary outcomes are the differences in heart rate and blood pressure between the binaural beat audio and the control group, as well as the mean changes in anxiety scores, heart rate and blood pressure within each group (intervention and control) over time.
Interventions
Binaural beats (Happiness Frequency 10Hz Binaural Beats, Greenred Production) through earphones positioned by a single researcher in the operating theatre. The researcher would first switch on the MP3 player and test the volume, as well as ensure that the subject was comfortable with it. Patients were exposed to the beats 10 minutes before the start of cataract surgery until immediately after completion of surgery.

The researcher would first switch on the MP3 player and test the volume, as well as ensure that the subject was comfortable with it. Patients were exposed to the beats 10 minutes before the start of cataract surgery until immediately after completion of surgery. Cataract surgery was performed under topical anaesthesia, consisting of proparacaine hydrochloride 0.5% (Alcaine, Alcon, Puurs, Belgium). All patients were also given non-preserved intracameral lidocaine hydrochloride 1% at the commencement of the surgery. No oral or intravenous sedation were used. Phacoemulsification was performed in the standard manner by two ophthalmologists. Surgical duration was approximately 40 minutes.
