Infrared light
During the procedure, a doctor directs an intense beam of infrared light at the hemorrhoid. Heat created by the infrared light causes scar tissue, which cuts off the blood supply. The hemorrhoid dies, and a scar forms on the wall of the anal canal. The scar tissue holds nearby veins in place so they don't bulge into the anal canal.
A downside to this technique is that only one hemorrhoid can be treated at a time. Other hemorrhoids can be treated at 10 to 14 day intervals.
Bleeding from the anus occurs 7 to 10 days after the procedure, when the hemorrhoid falls off. Bleeding is usually slight and stops by itself.
There are risks associated with this technique including: considerable pain during the procedure, bleeding from the anus, infection in the anal area and possibly a temporary inability to urinate.
The procedure can be carried out in a Doctor's office...no hospital stay is required.
Nowadays, laser surgery is more common.
