Surgical method: Incisions are made very closely to each other, parctically cutting apart the tiny branches. Because capillaries have no muscular layer, they can not contract and bleed intensely, which disturbes vision. A swab is used in one hand for instant compression of the treated area. After few minutes bleeding stops and the tiny, bloodless capillary fragments are visible through the skin. Bleeding can not appear later, because all connections have been destroyed. This method does not have any disadvantages.
