In the world of plastic surgery, more and more doctors have started to look into the use of augmented reality. Microsoft HoloLens, in particular, have become a valuable tool among plastic surgeons.Using the technology behind augmented reality, surgeons can compare the potential results of surgery to 3D rendering of the results desired by clients. This in turn allows them to change the appearance of the person so that it more closely matches the goals of their clients. It also reduces the time that patients spend on the operating table.
