So in a fixed power scope, such as the 4x32, the object in view is magnified 4 times. An object would appear to be 4 times closer than it would with the naked eye. Therefore, a higher number has a greater magnification. Most scopes sold today are variable power, such as the 3.5-10 mentioned above.
Surgical treatment of hemorrhoids. Surgery for hemorrhoids is reserved for those people who do not respond to more conservative therapies. The important factor to consider is how much trouble the hemorrhoids are causing. Occassionally, hemorrhoids that become quite large, or bleed so much, will require surgery.
During the procedure â which may be performed either without anesthesia or with local anesthesia â the doctor will insert an instrument with a light and lens, called an anoscope, through the anus. The doctor uses a special banding tool to place a small rubber band around the hemorrhoid(s). The bands cut off the blood supply, causing the hemorrhoid to shrink. The band and the hemorrhoid will fall off in about one to two weeks. After the procedure, avoid straining or bearing down.
