Brief summary
This project is to evaluate the benefits of utilising virtual reality (VR) headsets with the aim of reducing peri-operative anxiety in cataract surgery and hence reducing the need for sedation in patients with significant stress levels noted during preassessment. This is a novel study, and with the increased use of VR technology throughout medicine, we may be able to offer our patients alternative management modalities to reduce stress and reduce need for medications with their subsequent potential side effects. It may also improve the quality of care provided and patients' experience with the cataract extraction procedure and might reduce the social care burden associated with standard sedation procedures. All patients will need to fill a quick preoperative anxiety and information scale questionnaire to assess their level of anxiety utilising The Amsterdam Preoperative Anxiety and Information Score. Patients will be randomised into 2 groups: 1. Conventional group: patients will be prepared as per the standard routine clinical and further explanation of the procedure will be given. Before proceeding to the anaesthetic room, the patients will complete the anxiety score questionnaire again and given the option to proceed with sedation or opt out. 2. Interventional Group: patients will be prepared as per the standard routine clinical care; they will then be wearing the VR mask for 10 minutes. Before proceeding to the anaesthetic room, patients will complete the anxiety score questionnaire again and given the option to proceed with sedation or opt out. Post operation, a record will be taken of the surgeon's decision on whether they want the second eye cataract surgery to be done under sedation (this is already standard practice at our centre). Finally, the patient will be asked to fill in one final grading score on whether they are happy with their decision to take/not take sedation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Anxiety score | 10 mins following intervention | Percentage of reduction in Anxiety score in interventional group as compared to control group as assessed using the Amsterdam preoperative anxiety and information score |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient required sedation after intervention | 10 mins | Percentage of patients who were happy with their decision to undergo/not undergo sedation in intervention vs control group. |
| Patient required sedation for second eye surgery | Following surgery, approximately 30-60 mins following intervention | Percentage of patients who the surgeons would list their second eye for sedation in intervention vs control group. |
