Can astigmatism cause crossed eyes?

The answer is no, not always. In fact, in most cases, it is the other eye that is crossed, not the one with the astigmatism.

The eyes are normally symmetrical, meaning they act and look the same on both sides. When one eye is crossed, the other eye is likely to be also crossed.

There are three main types of astigmatism:

1. Myopic astigmatism occurs when the cornea is abnormally curved.

The cornea is the clear front part of the eye. It consists of a thin piece of tissue that bends in the direction of the light.

Astigmatism is the result of the cornea being abnormally curved in the direction of light. Light passes through the front surface of the cornea, which then bends as it passes to the back of the eye.

2. Hyperopic astigmatism occurs when the cornea is abnormally curved downward.

The cornea is again abnormally curved in the direction of light.

3. Mixed astigmatism occurs when the cornea is abnormally curved in both directions.

In some cases, an eye doctor will diagnose a person with either myopic or hyperopic astigmatism, but not both.

What are the symptoms of crossed eyes?

The symptoms of crossed eyes may include:

  • Having blurry vision
  • Difficulty finding the object you are looking for
  • Feeling dizzy or lightheaded
  • Having double vision
  • Having eye pain
  • Having eye twitching
  • Having vision loss

An astigmatism diagnosis

If you have crossed eyes, your eye doctor will most likely diagnose you with astigmatism.

A doctor will do an eye exam and measure the corneal curvature. Your doctor will then perform other tests to confirm the diagnosis. These tests might include:

  • An eye exam. The doctor will put a special device called a Topcon TMS (Topcon Technology Management System) into your eye to examine the corneal curvature.
  • A pachymetry test. With the device, the doctor will assess the thickness of the cornea.
  • An eye pressure test. The doctor will place a special device called an IOL (intraocular lens) into your eye to check the pressure in your eye.

How is crossed eyes treated?

The goal of treatment for crossed eyes is to restore the image and vision to normal.

The treatment options for crossed eyes depend on the type of astigmatism you have. Some of the treatments may include:

  • Myopic astigmatism
  • Presbyopia. This is loss of power in the eye due to age. Presbyopia is corrected with eyeglasses or contact lenses.

Hyperopic astigmatism

  • Laser surgery. This is a procedure where a laser is used to reshape the cornea.
  • Intense pulsed light (IPL) treatment. This is a laser treatment that can be used to correct the astigmatism.

Mixed astigmatism

  • Blurred vision correction. This is surgery to correct the abnormal shape of the cornea.

What is the outlook for crossed eyes?

After your treatment for crossed eyes, your vision may not be completely restored. Your vision may also change over time.

However, there are options to help you manage your vision. These include:

The use of eyeglasses. You may need to wear eyeglasses or contact lenses to correct your vision. You can also use eyeglasses as a protective device while you are using contact lenses.

The use of a laser or IPL treatment. This may be used to correct the vision.

There is also a surgical procedure called the Limbal Relaxing Flap (LRF) procedure. It is an outpatient procedure that involves creating a flap of tissue from the back of the eye to the front of the eye. The flap is then folded over the cornea. This helps improve vision.

However, these treatments may not be appropriate for everyone. You should talk to your doctor before starting any treatment.

Can crossed eyes cause myopia and hyperopia?

There are many causes of myopia and hyperopia. Some of the most common causes include:

  • Age. Some people lose vision over time as they age.
  • Family history. Your family may have a high risk of developing myopia or hyperopia.
  • Genetics. Your genes can affect your vision.
  • Lifestyle. Certain lifestyle choices may cause you to develop myopia or hyperopia.
  • Eye injury. You may be more likely to develop myopia or hyperopia if you have a near-sighted eye injury.
  • Eye surgery. A corneal transplant, eye injury, or cataract surgery can cause myopia or hyperopia.

Can crossed eyes affect your vision?

If you have crossed eyes, you may notice that the blurred vision may affect your vision. This is because the different refractive errors that you have together may cause your vision to become distorted.

Can you prevent crossed eyes?

If you are worried that crossed eyes could affect your vision, you should speak to your doctor. You should also speak with your optometrist. This is an eye doctor who specializes in vision. They can help you determine whether any corrective lenses are needed.

The optometrist can also make changes to your prescription to help correct your vision if necessary.

A corneal transplant can correct myopia and hyperopia. This procedure is only performed in cases where the cornea is too damaged for surgery. You may also need to have a cataract surgery to correct your astigmatism.

If you have a child with crossed eyes, you should speak to your child’s optometrist. They will be able to discuss the treatment options and manage your child’s vision properly.
