Astigmatism

Astigmatism, unlike normal vision, occurs when the cornea is shaped like a football (more curved in one direction than the other) and often occurs in combination with  myopia (nearsightedness) and  hyperopia (farsightedness). This causes light to focus in more than one point on the retina, resulting in blurry and distorted vision.

Causes of astigmatism:

  • Heredity
  • Lid swellings such as chalazia
  • Corneal scars
  • Keratoconus

Diagnosing astigmatism:

The doctors at Vold Vision 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. One of our doctors 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.

Treatment of astigmatism:

Glasses and contact lenses are used by many for the temporary treatment of astigmatism. However, there are a number of  vision correction procedures  that Dr. Vold can perform that can surgically reduce or eliminate astigmatism.

Other types of refractive errors include:  nearsightedness,  farsightedness  and  presbyopia.
