Astigmatism

What You Should Know

Astigmatism is a common eye issue present in about one in three people. Most people who are long-sighted or short-sighted also have astigmatism. Astigmatism is a condition where the cornea of one’s eye looks like a distorted circle. Ideally, the cornea should be a perfect circle, but due to a slight difference in the shape of the eyeball, items appear closer or more distant, and you might have blurry vision. At Modern Eyes Optometry in Carlsbad, you can access quality eye treatment for astigmatism and various eye issues. Here’s a closer look at astigmatism.

Causes of Astigmatism

Genetics is the leading known cause of astigmatism. If you weren’t born with it, astigmatism can develop due to other issues such as eye surgery, injury, or after developing keratoconus. Prolonged eye strain and reading under dim lights make it difficult for your eyes to focus, thus putting you at risk of developing astiagmatism.

 

The Different Types of Astigmatism

Astigmatism is a general term for issues relating to how light bends when it enters the eye. The type of astigmatism a patient has is determined by how well they can see at close or distant proximities. They include:

• Hyperopic Astigmatism: This is a condition commonly referred to as long or far-sightedness.

• Myopic Astigmatism: This is a condition commonly referred to as short or near-sightedness.

• Mixed Astigmatism: This is a combination of the two conditions above.

 

Other less common types of astigmatism include:

• Regular Astigmatism

• Corneal Astigmatism

• Irregular Astigmatism

• Lenticular Astigmatism

 

Common Symptoms of Astigmatism

No two people with astigmatism have the same symptoms. In fact, most people show no symptoms at all. However, common symptoms likely to show up in people with astigmatism include:

• Headaches

• Eyestrain

• Blurry or distorted vision

• Difficulty seeing at night

• Squinting

Most of these symptoms could point to other underlying severe health issues. Consider talking to an eye doctor for a complete eye exam to determine whether or not you have astigmatism

Astigmatism Treatment Options

While mild astigmatism doesn’t require treatment, if astigmatism causes vision problems, treatment is necessary. Top treatment options for astigmatism include:

Corrective Lenses

Our optometrist may prescribe eyeglasses or contact lenses to treat astigmatism. Most people prefer corrective lenses because this option is the least invasive.

Refractive Surgery

If you have a severe case of astigmatism, the optometrist may recommend refractive surgery to reshape the cornea. This procedure seeks to correct astigmatism permanently.

Orthokeratology

Also known as Ortho-K, orthokeratology is an intricate treatment that uses hard contact lenses to correct the abnormal curvature of your cornea temporarily. The patient wears the contact lenses for regular intervals, hoping to gradually reshape the cornea to normal. Note that you can only enjoy clear vision along with other benefits of Ortho-K when you wear contact lenses. Once you remove the lenses, your vision returns to its original state.
