In 1975, the laser was used in surgery.Lasers were to remove tissues within the minimal beating of its surrounding.theodore h.maiman created the first laser out of ruby in 1960 But, in 1961, only a year after its invention, a physicist and an ophthalmologist had used a ruby laser to destroy a tumour on the retina of a human eye. Later laser surgery was developed for corneal sculpting. Lasers were also used to cut through tissue. lasers were also used for removing other things.in 1962,lasers were being used to remove things such as tattoos,birth mark, stretch. marks, leg veins acne scars port wine stains."This concept states that the risk of scarring and damage to normal tissue can be minimized by the use of a laser system that selectively reacts with a single target within the skin.The latest laser development in the field of skin resurfacing is the Erbium: YAG laser. This laser is used to perform superficial skin resurfacing for minor wrinkles, pigmentation changes, and mild acne scarring."
