VR for Cataract Anxiety Lowering Management--A RCT Study
260 participantsStarted 2026-06-01
Plain-language summary
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.

. Suffering from severe hearing impairment, unable to comprehend VR video content.
. Those who suffer from cognitive dysfunction or mental illness and are unable to cooperate in completing the scale assessment.
. Suffering from severe macular diseases, glaucoma, or other ocular diseases that may affect surgery or interfere with the assessment of tension level.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial uses virtual reality to help patients understand and consent to cataract surgery — can you explain how that VR experience would actually work in practice, and whether it would replace or supplement our usual consent conversation?
2Since this study isn't recruiting patients yet, how soon do you think it might open, and is there a standard way you currently manage pre-surgery anxiety that I could benefit from in the meantime?
3The trial measures anxiety using a numerical rating scale before and after the VR experience — do you think my current level of anxiety about cataract surgery is significant enough that participating in a study like this would be worth considering?
4Because this is listed as phase 'NA' and focuses on a consent and anxiety management tool rather than a new drug or surgical technique, what are the realistic risks of being in this study compared to just going through the standard informed consent process?
5If I'm already scheduled or planning to have cataract surgery soon, would waiting to see if this trial opens affect my treatment timeline in any meaningful way?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
The change of anxiety level evaluated by numerical rating scale (NRS)
Timeframe: collected before the intervention (VR video or conventional preoperative instructions) , immediately before the surgery, and immediately after the surgery
