Lasers are used contained by eye surgery (lasik, etc.), vascular surgery, and many other places contained by medicine. Laser down removal is another method of use, but physicians aren't always required.
They cauterize the wound, (stop the bleeding), as rhey cut.
Very restructured.
They also use ruby lasers to remove tattoos/plastic surgery.
Many times a laser is use to remove a gallbladder, a laser does the same as electracautery (meaning burning the vessel to stop bleeding. Lasers are also used in eye surgey to cut down on bleeding. The strange types of lasers are used for aesthestics.to remove hair folicles, birthmarks, blemishes.
