 Astigmatism


 

Who experiences astigmatism:

 

  • A common condition
  • Asymmetrical corneas are more severely curved (shaped like a rugby ball instead of a soccer ball)

 

Symptoms of astigmatism:

 

  • Can exist in combination with nearsightedness and farsightedness
  • Objects both near and far are blurred or distorted producing an effect similar to looking through a pane of wavy glass
  • Constant squinting of the eyes
  • Inability to read small print

 

Causes of astigmatism:

 

Because of an irregular shaped cornea:

  • Light is correctly focused along one axis, but incorrectly along the other
  • Light entering the eye is not focused on a single point on the retina

 

What to do:

 

  • Astigmatism can be diagnosed by an eye care professional through a variety of tests, including a simple vision test, light refraction test, cornea measurement, or electronically mapping the surface of the eye
  • The uneven distribution of light is corrected by refocusing light rays on a single plane, this is done in a number of ways:
  • Spectacles
  • Contact lenses - are uniquely designed to meet the special vision correction needs of people with astigmatism
  • Surgery - Astigmatic Keratotomy is performed through LASIK laser technology (photorefractive keratotomy) or by manual incisions (radial keratotomy), this procedure reshapes the cornea by removing small pieces of tissue from the cornea
