Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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.

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.

Statistical methods / analysis
Sample size calculation was conducted using G*Power 3.1.9.7. The parameters used for the sample size calculation were effect size = 0.20, alpha value = 0.05, power = 0.80, number of groups = 2, number of measurement = 2 times. The estimated sample size was 31 per group with total sample size of 62.

Statistical Package for the Social Sciences (SPSS) version 25.0 will be used for data analysis. Independent sample t-test and Pearson chi-square statistic will be used to compare numerical and categorical variables between groups. Paired sample t-test will be used for pre and post test measurements within each group. A p-value of < 0.05 will be taken as a significant result.

Summary
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.
