Modulating Intraoperative Vasectomy Pain Using the SmileyScope Virtual Reality Interface

Vasectomy is a safe and effective procedure for permanent sterilization in males. More than 500,000 vasectomies are performed annually in the United States, and that number is expected to grow rapidly in the coming years. The procedure is safe and can be quickly performed in an outpatient setting. Complications of vasectomy are rare, and can include hematoma and infection, spermatic granulomas, and post-vasectomy pain syndrome in rare cases. Like all outpatient surgical procedures where the patient is not under general anesthesia, vasectomies involve intraoperative and immediate post-operative pain. While use of the no-scalpel technique and local anesthetic reduces intraoperative pain, expected operative pain is still one of the main reasons patients cite for not undergoing the procedure.

In our current study, the investigators aim to further modulate intraoperative pain using virtual reality goggles. In clinical trials, the SmileyScope device has been shown to reduce procedural pain in the pediatric population during venipuncture or intravenous cannulation. Results from those studies showed a statistically significant reduction in pain during intravenous procedures in the emergency department. This VR headset is undergoing study for approval by the U.S. Food and Drug Administration (FDA) to reduce pain and anxiety in patients aged 4 years and older undergoing needle blood draw or injection procedures. Currently, this device has been granted entrance to the FDA Safer Technologies Program. In this study, the SmileyScope virtual reality interface is considered an investigational device because it is not yet approved for use in adult males undergoing vasectomy. The aim of this study is to investigate whether this same virtual reality modality can be utilized to reduce pain during vasectomies.
