Eye laser therapy. Artwork showing three stages in laser therapy to correct corneal deformation. The outer layer of the cornea is cut open and a flap (left) pulled back. The laser (centre) is then used to reshape the stroma, the middle layer of the cornea. At right, the flap is replaced. This technique can be used to correct conditions such as astigmatism, myopia (short-sightedness), and hyperopia (long-sightedness).
