This study aims to determine the effect of virtual reality glasses on pain and anxiety levels in colorectal surgery patients. This study is a single-center, parallel-group, open-label, randomized controlled clinical trial. This study will be conducted with 60 patients who underwent colorectal surgery between August 2025 and December 2025. Participants will be randomized into two groups as the intervention group (n=30) and the control group (n=30).

All patients in the experimental and control groups will be asked to fill out the "Informed Consent Form" the day before the surgery, and the patients who agree to participate in the study will be asked to fill out the "Patient Introduction Form" and the "State Anxiety Scale" by the researchers.

The "Simulator Illness Questionnaire" used in the Virtual Reality disease field will be applied to the experimental group to determine their physiological conditions before the application. Then, a relaxing music-backgrounded video containing images of nature will be watched with virtual reality glasses for 10-15 minutes the day before the surgery. Then, the "Simulator Illness Questionnaire" and the "State Anxiety Scale" will be filled out again.

The "Simulator Illness Questionnaire" will be applied to the patients 2 hours after their transfer from the postoperative care unit to the clinic, which is the most appropriate time after the surgery, when their vital signs have stabilized and clinical compliance has been achieved, and their physiological conditions before the application will be determined. Then, the patients in the experimental group will be asked to watch a relaxing music-backgrounded video containing images of nature for 10-15 minutes with virtual reality glasses. The researcher will perform the video with virtual reality glasses in the patient rooms and beds. Afterwards, the "Simulator Disease Survey" will be repeated. There will be no compelling effect that will negatively affect the health of the patients during the application, and the application will be terminated when the patients feel uncomfortable. A safe environment will be created so that there are no objects around the patients that they can bump into or trip over. A 5-10 minute trial period will be performed at the beginning with the observer and the virtual reality glasses will be applied. The patient will be able to end the study at any time. If the patients use glasses/lenses, compliance will be checked.

No intervention will be applied to the control group patients and the routine practices of the clinic will continue.

All patients in the experimental and control groups will be assessed for pain with the Visual Analog Scale (VAS) at the 2nd and 4th hours and the "State Anxiety Scale" will be applied.
