Biomedical engineer Lisa Ferrie, head of the 3D planning service at the trust, made a model of the patient’s skull so the surgical team could rehearse the operation before they did it.

She said: “This technology enabled the team to study her anatomy in detail and prepare for the procedure with unparalleled accuracy.

“Seeing the model and knowing it contributed to this ground-breaking surgery is incredibly rewarding.”

Ms Kaviya was left with a tiny scar near her left eye, but was back at work caring for stroke patients three months after the surgery.

She said: “When I had the operation I thought I was possibly going to stay in the hospital for weeks or months and I was home in days.

“I had double vision for about three months but everything else was OK.”
