Infrared Coagulation (IRC) is a widely used method for treating haemorrhoids and is usually performed immediately after a colonoscopy while the patient is still sedated. The procedure involves applying a probe which delivers a burst of infrared light above the haemorrhoid. This cuts off the blood supply, compressing and sealing the haemorrhoid veins. IRC is relatively painless, especially when performed in conjunction with colonoscopy.
