(HealthDay News) – For patients undergoing cataract surgery, a binaural beat-music mix or music-only intervention correlates with less anxiety and reduced systolic blood pressure, according to a study presented at the annual meeting of the American Academy of Ophthalmology, held from Nov. 10–13 in Chicago.

Pornpattana Vichitvejpaisal, MD, of Chiang Mai University in Thailand, and colleagues examined the anxiolytic effects of binaural beat and musical interventions during cataract surgery in a prospective randomized controlled study. Participants were randomly allocated to binaural beat, musical intervention, or control; each group consisted of 47 patients matched for age, gender, cataract type, and other health factors.

The researchers found that, compared with the control group, there was a significant decrease in anxiety level and in systolic blood pressure in the binaural beat and musical intervention groups.

“As populations in many parts of the world grow older, it’s increasingly important for ophthalmologists to explore new ways to improve patient care for seniors,” Vichitvejpaisal said in a statement. “Our study shows significant emotional and physiological benefits from adding binaural beats to music therapy for cataract surgery patients. This provides a simple, inexpensive way to improve patients’ health outcomes and satisfaction with their care.”
