Breaking New Ground: How AI Became a Surgeon’s Second Pair of Eyes

In a groundbreaking moment for medical innovation, a man in England has become the first patient to undergo live AI-assisted brain surgery, which protected his sight during the removal of a brain tumour. This landmark procedure represents a pivotal shift in how artificial intelligence is being integrated into complex surgical settings, transforming the operating room from a purely human domain into a human-AI collaborative space.

Rhys Hibbert, a 48-year-old from Bedfordshire, was diagnosed in December 2024 when he collapsed during a walk and suffered a seizure. According to Hibbert’s doctors, the tumour would have continued to threaten his sight and could ultimately have led to blindness. Facing a potentially devastating outcome without intervention, Hibbert made the bold decision to volunteer for an experimental procedure that would place him at the intersection of traditional surgery and cutting-edge technology.

What makes this operation particularly significant is not that artificial intelligence performed the surgery—it did not. Instead, during the surgery, the AI analysed the live surgical video feed in real time, rather than using pre-surgery scans, helping the surgical team make more precise decisions by highlighting critical structures at the base of the brain.

The technical achievement becomes even more impressive when considering the stakes involved. In this part of the brain, the pituitary gland — which is the size of a marble — sits tightly blood vessels and nerves controlling vision. A margin of error of just a millimetre can prove critical, potentially leading to death, blindness or stroke. This extreme precision requirement made the situation ideal for AI assistance, as the technology could continuously analyze the surgical field and alert surgeons to anatomical dangers in real time.

Dr Sophia Bano, an associate professor in robotics and AI at University College London and the technical lead for the system, said the technology had learned from hundreds of surgical videos, exposing it to a breadth of surgical examples that could take a surgeon many years to encounter. The AI technology uses colour coding to help surgeons identify tiny anatomical structures in the brain and distinguish them during highly delicate procedures. This training approach means that the artificial intelligence brings collective surgical experience to bear during each operation.

The operation was carried out at the National Hospital for Neurology and Neurosurgery (NHNN), part of University College London Hospitals (UCLH), as part of a clinical trial using AI technology developed in-house at University College London and funded by the National Institute for Health and Care Research (NIHR). The fact that this homegrown technology emerged from within a leading research institution underscores the concentrated expertise required to develop such systems.

Perhaps most importantly, the outcome validates the approach. The operation successfully removed the growth and protected his vision. He said: “It feels like I’ve got a 360-degree panoramic view of everything around me.” He was walking without glasses or a walking stick within a week and has since returned to work as a customer service manager. For Hibbert, what could have been a career-ending loss of sight became a complete restoration of normal function.

This pioneering surgery opens a door to fundamentally rethinking how complex procedures are performed. The significance lies in the possibility of giving surgeons a real-time, machine-assisted view of anatomy that may otherwise be hidden from them. As this technology matures and expands to other surgical specialties, it promises to transform patient outcomes not just in neurosurgery, but across the medical field. The human surgeon remains in complete control, but now with an artificial intelligence partner providing superhuman attention to detail.
