Laser surgery differs from laser treatment as it generally means that it is invasive. Its main aim is to cut the tissue using a laser instead of a scalpel and is regarded as being highly accurate which is why they use it for delicate procedures such as eye surgery.
Soft tissue laser surgery is when the soft tissue with a high water content is struck
with a laser beam which vaporizes it, the focal point can be .1 mm but the general
measurement used is .4 mm. The same laser when it is defocused can be used in cauterisation
of blood vessels and lymphatic's and therefore decrease post-
Better use still is the laser than a standard scalpel as the surgeons choice because
as it cuts through, it has the ability to kill bacteria, viruses and fungi and therefore
decreases post-
Laser eye surgery uses a type of laser called an excimer laser, often times it is also termed properly as an exciplex laser and is a form of ultraviolet laser.
This type of laser used in eye surgery does not cut or burn the soft skin on the surface of the eye but instead adds just enough energy to disrupt at the molecular level the bond if the tissue. Essentially, the tissue is vaporised into the air in a controlled manner of ablation.
The common misconception that lasers emit a high temperature beam of light is wrong, in laser eye surgery, an ultraviolet beam disrupts the area of skin precisely and is perfect for surgeries like LASIK.
