“It is early days for this technology but we are very bullish on how augmented reality and virtual reality are going to be key technologies in the operating room of the future,” says Touch Surgery co-founder Dr Jean Nehme (pictured).

8vc, the US VC fund which backed Oculus Rift, led the new funding round. The money will be used to boost staff level to about 200 split equally between London and New York.

Touch Surgery, founded by two surgeons, will use a Microsoft Hololens headset to display live video feeds of surgery overlaid with instructions, step-by-step guide and commentary.

The product, to be launched next year, will be called Go Surgery. It is expected to cut the cost of surgical training.
