The Causes and Treatments for Astigmatism

Aug 15, 2021

What is Astigmatism?

Astigmatism is a common vision condition that affects the shape of the cornea or lens of the eye. Unlike normal corneas or lenses that are round, in astigmatism, they have a more oval or irregular shape. This irregular shape causes blurred or distorted vision at all distances.

Symptoms of Astigmatism

Astigmatism can cause various symptoms, including:

  • Blurred vision
  • Difficulty seeing details or fine print
  • Eyestrain
  • Squinting
  • Headaches

If you experience any of these symptoms, it is essential to consult with an eye care professional to determine whether you have astigmatism and discuss suitable treatment options.

Types of Astigmatism

Astigmatism can be classified into three types:

  1. Myopic astigmatism: This occurs when one or both of the principal meridians of the eye are nearsighted.
  2. Hyperopic astigmatism: This occurs when one or both of the principal meridians of the eye are farsighted.
  3. Mixed astigmatism: This occurs when one principal meridian is nearsighted, and the other is farsighted.

Causes of Astigmatism

The exact cause of astigmatism is still unknown. However, it is believed that both genetic and environmental factors play a role in its development. Some common causes include:

  • Genetic factors: Astigmatism can be inherited from parents or other family members.
  • Irregularities in corneal shape: When the cornea is not perfectly curved, astigmatism can occur.
  • Eye injuries or surgeries: Trauma to the eye or certain surgical procedures may contribute to astigmatism.

Treatments for Astigmatism

Fortunately, there are effective treatments available to correct astigmatism and improve vision. The most common treatment options include:

1. Eyeglasses

Eyeglasses with special lenses are often prescribed to compensate for the irregular shape of the cornea or lens. These lenses help to focus light properly onto the retina, resulting in clear vision.

2. Contact Lenses

Contact lenses are another popular option for correcting astigmatism. There are specially designed toric lenses that provide clear vision by counteracting the irregular shape of the cornea or lens.

3. Laser Eye Surgery

Laser eye surgery, such as LASIK or PRK, can also be a viable treatment for astigmatism. These procedures reshape the cornea, correcting the irregular curvature and improving vision without the need for corrective lenses.

4. Orthokeratology

Orthokeratology, also known as ortho-k, involves wearing specially designed gas-permeable contact lenses while sleeping. These lenses gently reshape the cornea during the night, providing clearer vision during the day without the need for glasses or contacts.

5. Refractive Lens Exchange

In cases of significant astigmatism, refractive lens exchange may be recommended. This procedure involves removing the natural lens and replacing it with an artificial intraocular lens (IOL) that corrects the astigmatism.

Consultation and Next Steps

If you suspect you have astigmatism or are experiencing any of the associated symptoms, it is crucial to schedule an appointment with an eye care professional. They will perform a comprehensive eye examination to diagnose the condition accurately and recommend the most appropriate treatment option for you.
