Optics and Lasers in Medicine

There are some surgical operations that are perplexing to perform with the conventional scalpel. Initial trials with laser beam displayed that a finely focused beam from a carbon dioxide gas laser could cut through human tissue smoothly and neatly. The surgeon could direct the beam from any angle by using a mirror attached on a portable metal arm. Therefore, now a day’s laser beam is the most desired tool which is used as a standby for the conventional blade to perform problematic surgeries. Lasers were considered as most effective in operating on parts that are easy to reach-areas on the body's exterior, including the ears, skin, mouth, eyes and nose. But in recent years doctors have established the remarkable improvement in emerging laser techniques for use in internal exploration and surgery. For illustration lasers are gradually used to clean plaque from people's arteries.
