Virtual Reality (VR) and Augmented Reality (AR) are redefining the landscape of Medical Technology, bringing cutting-edge innovation to the healthcare sector.

In the rapidly evolving world of medical technology, Augmented Reality (AR) and Virtual Reality (VR) are making significant strides, revolutionising diagnosis, treatment, therapy, and education within the healthcare sector.

### Surgical Training, Planning, and Procedures

VR offers immersive, risk-free simulations for surgeons to practice complex procedures, while AR provides real-time guidance by overlaying critical digital information onto a patient's anatomy during surgery. This integration enhances surgical accuracy and safety, giving surgeons an "X-ray vision" through advanced imaging like CT or MRI scans directly in their field of view [1][3].

### Patient Therapy and Treatment

VR is being utilised effectively in pain management, distracting patients from discomfort via immersive environments, and in mental health to treat anxiety disorders, PTSD, and trauma through exposure therapy. AR, enhanced with AI, is pushing psychiatric treatment forward by simulating social interactions and real-world scenarios, potentially improving social and occupational functioning for conditions such as autism spectrum disorder and chronic mental illness [1][4].

### Emergency and Diagnostic Assistance

AR applications aid in emergencies by showing the real-time location of automated external defibrillators (AEDs) and improving procedures like blood collection through projecting an accurate image of veins onto the patient’s skin, reducing errors and improving venous access [3].

### Medical Education and Research

Both VR and AR facilitate immersive education for medical students and healthcare professionals, improving understanding of complex subjects and enhancing practical skills. AR enables visualisation of complex molecular and patient data in 3D, enhancing comprehension and innovation in medical research [1].

### Ethical Implications

The use of AR/VR involves extensive data capture, including sensitive health and behavioural data. Ensuring the confidentiality and protection of this information is critical to prevent misuse or unauthorised access. Other ethical concerns include the risk of widening health disparities, psychological effects, informed consent, dependence on technology, clinical validation, and oversight [1][2][3][4].

One notable example is Pear Therapeutics' reSet app, a prescription digital therapeutic approved by the FDA, which uses VR for outpatient treatment for addiction. Medical technology is under intense scrutiny due to its ability to impact lives, and ethical considerations must be addressed to maximise benefits while minimising risks.

As these technologies rapidly evolve, it is essential to ensure interventions are evidence-based and clinically validated to avoid ineffective or harmful practices. Fujitsu has developed a virtual reality heart simulator to improve student understanding of the heart's complex structure and function, while AR is being used for patients who are visually impaired, such as Nueyes smart glasses that allow patients to "see" the outside world.

In conclusion, AR and VR are reshaping healthcare by improving surgical precision, enhancing therapeutic approaches for mental and physical health, and revolutionising medical education. However, these advancements come with ethical challenges that require careful regulation, patient-centred implementation, and equitable access to maximise benefits while minimising risks [1][2][3][4].
