Music's Impact on Preoperative Anxiety: Heart Rate Variability Study During Cataract Surgery

Music will be played through individual headphones (BOSE AE2®). The headphones give the impression of personalized music that only the patient can hear. Patients will have a mask over their eyes to limit visual aggression. The songs will be pre-recorded on a digital tablet (Samsung Galaxy®) allowing the broadcasting of music programs. Patients will have the choice to listen to a song according to their musical preferences among 16 different musical styles. The volume will be adapted to the level that suits the patient.
