Summary:	INTRODUCTION: 75% of patients facing a surgical procedure experience anxiety. Under a procedure in a state of consciousness, such as ophthalmological surgeries, considerable levels of anxiety can be produced and, consequently, states of insomnia, pain and physiological stress. Sounds designed to enhance the patient experience can help not only distract, but also isolate distracting sounds or conversations in the operating theater. In the context of plastic surgery, the presence of music has been shown to improve the quality of surgical closure and patient anxiety. There is interest in evaluating interventions that stimulate psychological and physiological relaxation in patients. The purpose of this project was to assess sound-based interventions in the context of ophthalmic surgery, being useful to indicate or reject their potential use. OBJECTIVES: To assess the safety and effectiveness of sound-based interventions for patients undergoing ophthalmic surgery. METHODOLOGY: An explicit systematic search was performed using the highly sensitive search strategy in Medline (Ovid), CENTRAL LILACS, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, EMBASE, International Clinical Trials Registry Platform (ICTRP), and Web of science until July 1, 2021; conference proceedings and reference lists of retrieved studies were handsearched. Randomized controlled trials (RCTs) comparing sound-based interventions in different regimens or with other therapeutic alternatives for people undergoing ophthalmic surgery were selected. Two authors independently assessed trials for inclusion, data extraction and risk of bias assessment, disagreements resolved by consensus. A random effects meta-analysis was implemented. RESULTS: We examined 13,277 records; after reading the eligible trials, 14 published trials met the inclusion criteria. Sample sizes ranged from 40 to 330 participants, 4 trials describe the method used for randomization, and 2 trials used intention-to-treat analysis. The most common type of ophthalmic surgery was cataract surgery, followed by intravitreal injection. The overall risk of bias was 'low risk' in two trials and high risk in six trials. The effect in favor of the sound intervention was identified on the anxiety outcome (-0.73 95% CI -1.17 to -0.29) and on some secondary outcomes (heart rate, diastolic blood pressure, systolic blood pressure). Using the GRADE system, we rate the certainty of the evidence from low to very low for the results. CONCLUSION: The results of this study could suggest the potential use of sound-based interventions to reduce anxiety in patients undergoing ophthalmic surgery.
