VR for Cataract Anxiety Lowering Management (VR-CALM)
A Non-Randomized Controlled Trial of Virtual Reality Simulation of Intraoperative Audiovisual Experience to Reduce Anxiety in Cataract Surgery Patients
Cataract is currently the leading cause of blindness globally, and surgery is the only effective treatment. With the advancement of medical technology, cataract surgery is usually performed under topical anesthesia, which means patients will be awake during the procedure, able to see the light from the surgical lamp and hear the sounds of surgical instruments being operated. Some patients may feel nervous or scared due to unfamiliarity with the surgical process, which may lead to increased blood pressure, rapid heartbeat, and even affect their cooperation during the surgery.
Virtual reality (VR) technology is a new multimedia technology. By wearing VR glasses, patients can immerse themselves in a virtual world and see and hear realistic scenes. Through this study, the investigators aim to investigate whether allowing cataract patients to "experience" a surgical procedure in advance through VR glasses before cataract surgery can help alleviate their nervousness during the actual surgery.
