The aim of this research study is to evaluate the impact of immersive VR exposure on preoperative anxiety and pain. Additionally, to assess whether VR intervention would significantly alleviate pain and anxiety levels of patients undergoing complex spinal surgeries. Investigators hypothesize that the application of pre-operative VR-based intervention will alleviate anxiety and pain both pre- and post-operatively when it is used as treatment to complement standard care compared to standard routine care alone, and that it may lead to better outcomes and higher satisfaction in patients.
