Astigmatism is probably better known as just having blurry vision. The blurry vision, which is long term rather than being caused by a piece of fluff in the eye (and there's a lot of fluff out there), is caused by your eye's inability to focus on a point far away or up close. Strictly speaking, there's no astigmatism cure, but there are a large number of treatment options that one can take up if they want to try and improve their vision in certain situations. Probably the most obvious example of astigmatism treatment is by using basic eyeglasses which sharpen the focus of the object being focused on for the eye, so the eye doesn't have to do it itself.
Then there are the contacts. Contacts are usually a preferable cure to eyeglasses because they don't really need you to carry them around all the time - you carry them with your eyes. Contacts take the lens concept of the eyeglasses and bring them directly to the surface of your eye, but they have the same basic function, in that they sharpen the focus of your eye rather than leaving the task up to the lenses.
Perhaps the most comprehensive astigmatism cure is getting some sort of refractive surgery, such as laser eye surgery or not-laser surgery. Basically, laser eye surgery first maps out your eye and figures out what the problem with your eyes is, and then maps out a plan for how to fix this. Usually the problem lies in the lens itself in the various imperfections. The problem is that the lens is covered by the cornea, so you have to cut into the cornea to fix the lens. The areas are so small that is extremely difficult to do this safely by hand, making the lasers the ideal use for this particular problem. So basically, what happens is that the eye doctor uses suction cups to hold your eye still, like in A Clockwork Orange, and then they cut open a flap in the cornea, which makes your eyes go blurry - oh yeah, you'll be conscious for all of this, able to see the whole process happening. Fortunately, there aren't a ton of nerves in the surface of the eye, meaning you won't have much of a problem with pain, though there may be some discomfort. Localized anesthesia is used as well. Basically, once you cut the flap off, you can then work on the lens itself, which is then shaved down so that it can better process the images that your eye is seeing. In astigmatism surgery, it will attempt to fix the imperfections or may even install an artificial plastic lens underneath the top layer of your cornea. Regardless, when this finishes, you will immediately have better vision.
That said, there are certain risks with having lasers put to your eye. It can potentially cause eye problems, and it might not even fix the blurriness. That said, it does for most people, and in general astigmatism cure would most apply to LASIK surgery. The problem is that you might have other complications as a result from the surgery, such as dry eye syndrome or problems at higher altitudes or increased eye sensitivity. Also, if you rub your eyes ever again THEY FALL OUT. That's not true. Sorry. But basically, the point of all of this is that there's a decent amount that LASIK can fix, but with all surgeries, there's a general risk that comes with having your eye sliced open.
That said, there is no guaranteed sure fire astigmatism cure, as the ailment varies from person to person and has millions of different variations on different diseases. Some people respond extremely well to surgery, and some just need to use eyeglasses or eye contacts for their entire lives. There isn't much that can be done in terms of quick treatments, but it's a mild disease and is by no means dangerous to life and limb.
