The light beam produced by most lasers is pencil-thin and maintains its size and direction over very large distances. The varied effects of lasers occur because of differences in light intensity and wave length. In medicine, lasers are used as precise scalpels. They are useful in controlling bleeding, because their beam cauterizes or burns as it cuts. In some cases, lasers do not produce better results than using a scalpel.
Some procedures are less costly, and just as safely performed using traditional surgical techniques.
But, lasers are superior for other procedures. When wisely used, lasers can achieve clean and quick-healing surgical results. All Rights Reserved.
