Lasers have seen a lot of use in surgery, primarily as a tool to improve cosmetic features on the skin. The light removes blemishes, wrinkles, tattoos, and other markings by heating the cells until they burst open. It’s a painless operation and can help you both cosmetically and with your health. It sounds like science fiction, but surgical lasers are very much the present.
If any blood vessels are bleeding or you have cells that could turn into harbingers of disease, laser surgery is what gets rid of them. They can be used in conjunction with or in the place of traditional tools during surgeries and other procedures.
There are three different types of commonly used lasers, each with their own properties. The carbon dioxide laser is best used during surgery to stop bleeding and cut through tissue. The (and this is a mouthful) Neodymium: yttrium-aluminum-garnet laser is extremely powerful and can cut deeply while also letting blood clot quickly. This lets surgeons see and get into the body without the need for open surgery.
Finally, the Argon laser is the one used for most cosmetic applications, as well as for delicate procedures such as eye surgery. It has very limited penetration but is still used during cancer trials to delicately get rid of tumors, without the damage to surrounding cells of chemotherapy.
Almost every branch of medicine uses lasers in some way or form. They can treat the skin, teeth, stomach, bones, and other disorders. They are also becoming more common in the cosmetic industry to treat skin disorders and signs of aging for cosmetic surgery. If you go to someone in the medical field, then you’ll probably have at least one laser-based option available to you to treat whatever type of need you have.
