| Astigmatism |
Poor visual acuity is primarily caused by refractive errors. These
errors occur when the cornea is shaped in such a way that the images
we see do not focus directly on the retina.
Astigmatism
Astigmatism results in a blurring of all images, whether near or
far. Here, images focus on more than one point in front of, or
behind the retina. The result is that all images, whether near or
far, may be blurry. In mixed astigmatism, symptoms of myopia or
hyperopia are combined, resulting in the overall inability to see
images clearly. |

When making your decision about laser eye surgery, realize that many
of the methods of correction you may have already heard about, such
as glasses, contacts or traditional LASIK , are capable of correcting
these lower order aberrations.
