Astigmatism is a condition of the eye that will affect our vision when the cornea has an irregular shape. This eye defect is called a refractive problem because the there is a disparity in the level of refraction in the different focal points. The information below will help you to understand more about the causes and treatments for Astigmatism.

If you have been diagnosed with this eye problem, it’s because your cornea has an irregular curve shape so this will stop light from focusing on it correctly and this will lead to astigmatism or blurred vision. It is important to note that sometimes people with normal shaped cornea will also develop this condition because something is wrong with the curving of their eye lens. One of the treatments that your doctor might recommend is Astigmatism contacts.

astigmatism causes and treatments

Here are some of the causes of Astigmatism

There are two types of Astigmatism: Lenticular or Corneal.

1. Corneal Astigmatism is caused by structural defects which causes blurred vision when the cornea curve is uneven and is not refracting light correctly. You could have this eye problem because of:

  • Scarring from an eye infection, injury and some types of surgery.
  • A birth defect if you were born with a cornea that is curved unevenly.
  • A congenital problem because one or both of your parents have Astigmatism.
  • You were born prematurely or underweight.
  • A degenerative eye disorder called Keratoconus.

2. Lenticular Astigmatism will develop if there is a problem with the curving of the eyes lens instead of the cornea. You could have this problem because of diabetes. When your blood sugar level is too high, this will change the shape of your lens. But with the correct treatment, you can get rid of the diabetes and the astigmatism.

Treatments for Astigmatism

  • Eyeglasses: Some doctors will recommend eyeglasses as an alternative for contact lenses.
  • LASIK surgery: For this treatment, the doctor will use laser to fix the shape of the cornea.
  • Astigmatism contacts: These are usually used to treat the two types of Astigmatism. You can find different contact lenses on the market such as the soft, hard, bifocal, disposable, extended wear and rigid gas permeable. You can wear the rigid contacts during the daytime for an extended period until it improves the curvature of your eye. In most cases, the lenses will be used to maintain the new shape but the eyes will return to the original shape if you stop the treatment.

Now that you know about this common eye condition, you need to contact a medical doctor if you suspect that you acquire it from an injury or infection. Remember that this eye problem can be corrected or treated with treatment such as Astigmatism contacts, so it’s best to act quickly.
