Lasik can be used to correct some amounts of astigmatism, though this method of surgery is not usually favoured. Instead Lasik is favoured more for people for people who have myopia or short-sighted. Lasik is the procedure of correcting refractive error usually in people who are short-sighted and have myopia with 6 or less dioptres. In this procedure a flap is cut into the cornea and the underlying epithelium is ablated by the laser. Once complete the corneal flap folded back to its original position. As the cornea heals the cornea is flattened and corrects myopia. Unfortunately this procedure is less predicable for people who have astigmatism.
