For patients who only have portal sites (small incisions), the sutures are completely internal and will dissolve without having to be clipped or removed. A tail fiber, also known as a fiber optic patch cord, consists of a connector on one end and a cut end of the fiber optic cable core on the other. This allows the light signals to travel over much longer. Cuts in fibers and strands are usually a sign of contact between rope and any sharp edges. If one or more strands are cut, it is necessary to remove the afected area and resplice new eye if possible. If leaving no tail: slide down to knot, tilt sideways, cut. But how do I know if the suture is supposed to be cut very short, or leave a tag? I have been getting yelled at for leaving too.
