What is a laser?
The word laser stands for Light Amplification by the Stimulated Emission
of Radiation. It is a device that produces an intense beam of light of one single wavelength or color. There are many different types of lasers, each producing a unique wavelength of light.
What does it do?
First, it can cut, creating an incision like a scalpel. Secondly, the laser can
be used to vaporize tissue and tumors. Finally, the laser can coagulate or seal
small blood vessels as it cuts to reduce blood loss.
What are the advantages of using lasers in surgery?
Laser light can be focused to the size of the head of a pin, even to just
a few cells.
Tissue can, but does not have to be touched.
Laser fiber optics allow doctors to reach inaccessible places, often without
incisions.
It causes coagulation to reduce blood loss.
Lasers can be focused through body fluids.
Is recovery quicker from laser surgery?
The laser is extremely precise, therefore, it damages less of the surrounding
tissue. This tends to decrease swelling and promote quicker healing.
Is laser surgery less painful?
Although pain is very subjective, laser surgery tends to be less painful in most
cases than conventional surgery.
What conventional surgical procedures are being performed with a laser?
Lasers have vast applications. They are used in gynecology, orthopedics, urology,
neurology, ear, nose and throat, cardiovascular, and gastroentrology.
How do I find out if laser surgery is right for me?
First, discuss the possibility of laser surgery with your personal physician. This Web site can give you and your physician more information about laser services at Abbott Northwestern Hospital.
How much does the procedure cost?
Costs vary depending on the type of procedure, any special
instruments required, and the extent of the treatment. Laser surgeries and procedures
that are considered medically justified are usually covered by insurance and pre-authorized
before the scheduled procedure. As with any medical procedure, you should check
with your insurance carrier to see if there could be any out-of-pocket costs.
Which physicians perform laser procedures?
Physicians who perform laser procedures receive special education
in medical lasers, including classroom and hands-on training, and observation
of other experienced physicians.
