Astigmatism Treatment Harrisburg Pennsylvania

Astigmatism is a general inability of the eye to focus clearly at any distance because of uneven curvatures of the cornea, the eye's front window. Instead of being spherical, astigmatic corneas have more curvature in one meridian than the other. They are shaped similar to a football rather than a well-rounded basketball. Glasses and contact lenses are used by many for the temporary treatment of astigmatism. However, there are a number of vision correction procedures that can surgically reduce, eliminate, or treat astigmatism such as LASIK laser vision correction.

With astigmatism, the rays of light do not converge into a single point but form a line on the retina. There are various types of astigmatism including regular, mixed and irregular astigmatism. Currently, Excimer lasers in the U.S. are approved for treatment of regular and mixed, astigmatism. Recent advances in technology now allow for the therapeutic treatment of induced irregular astigmatism. In the future, this application may be expanded to include all types of irregular astigmatism. Patients who believe they have astigmatism should discuss this subject in further detail with their physician to gain a better understanding of the mechanisms in their case.

Your eye doctor can conduct a refractive evaluation to determine whether your eyes focus light rays exactly on the retina at distance and near. A visual acuity test will determine your ability to see sharply and clearly at all distances. Your eye doctor will also check your eye coordination and muscle control, as well as your eyes' ability to change focus. All of these are important factors in how your eyes see.
