Imagine a world where doctors could figure out how much they need to tuck away by simply checking an Oculus Rift. Or more impressively, imagine a world where medical students could train for their careers through the use of augmented reality, or where doctors would be able to find cancer cells through a quick scan.

Though it sounds like science fiction, it’s quickly becoming the reality that we live in. Thanks to amazing advances in the field of augmented reality, people around the world are finding their jobs to be easier than ever before. In recent years, augmented reality has been used to create tutorials in factories, help work out issues in warehouses, and even market real estate to people. This was a much needed and advanced application for this technology which was previously being used for marketing and sales purposes.

Augmented reality uses technology to blur the lines between “meatspace” and the virtual space. A good example of this would be using your cell phone to see visual guides from Google Maps on your phone’s camera view of the street as you walk to the store. Or, if you could lift your phone to see a basketball player’s stats as he slam dunks a basket. The most recent field to find uses in augmented reality is the medical world—and it’s become a hugely successful hit. More specifically, doctors are now starting to use the Microsoft HoloLens to better perform their surgeries.

In the plastic surgery world, more doctors than ever before have started to look into the use of augmented reality. Microsoft’s HoloLens, in particular, has become a valued tool in among plastic surgeons.

By using the tech behind augmented reality, surgeons can compare the potential results of surgery with the 3D rendering of clients’ desired results. This, in turn, allows them to create changes to a person’s appearances that more accurately line up with clients’ goals. It also reduces the amount of time that patients spend on the operating table.

The way it works is simple: doctors create a 3D image of the ideal patient outcome using morphing software, then overlay it on the actual patient’s face through the HoloLens’s technology. Then, they work to match the 3D rendered image with the actual patient’s face.

The HoloLens doesn’t interfere with a doctor’s ability to see the patient, nor does it interfere with a doctor’s ability to move freely in the surgical room. All it does is offer visual guidance on the procedure and help reduce the risk of a botched surgery.
