With advanced technology, everything that seems impossible in the past become easy to handle now. You can cure cancer, tho it does not completely vanish. And speaking of Astigmatism, actually, this is not a disease. From what we can grasp after long hours of researching, everyone has Astigmatism. It just with a different range. It is impossible for people to have full-moon like eyeballs. Yet, for Astigmatism, the cornea shape is way more prominent to the degree it is causing the refractive error. For mild to severe symptoms, it is arguably to treat it by wearing eyeglasses, contact lenses, or maybe by undergoing Lasik surgery.
