You may have heard the word astigmatism before, but you may not know that about a third of Americans are dealing with it. If you or a loved one is among the 33% contending with this refractive error, it helps to learn more about it. Here’s a closer look at the diagnosis and treatment options concerning this common condition.

What Is Astigmatism?

If the condition is significant, the shape of your eyeball isn’t perfectly round, and thus light can’t enter and bend evenly around it. Instead, the light will bend more in one direction than the other, leading to blurry or distorted vision. This shape issue can pertain to the cornea—which is diagnosed as corneal astigmatism—or the lens of the eye, which is known as lenticular astigmatism.

Other symptoms with this refractive error include eyestrain, headaches, and double vision. The condition is often paired with nearsightedness or farsightedness. Most people are born with astigmatism, but it can be caused by an eye injury or surgery later in life as well.

How Is It Diagnosed?

The condition is typically diagnosed during a routine eye exam. If or when you notice changes in your vision, you should always contact your eye care service, particularly if you haven’t had an exam in a while.

A keratometer or topographer is used to measure the curves of your cornea and lens. In addition, an autorefractor is used to shine light in your eyes and measure how it changes as it gets to the back of the eye. Using these diagnostic devices, your doctor will find and assess the severity. 

How to Manage It

If you have slight astigmatism, you may not need any treatment. However, if it’s more severe, the best treatment option is eyeglasses. Specially shaped, cylindrical lenses allow wearers to have clear and comfortable vision.

Another treatment option is orthokeratology, in which a patient wears rigid contact lenses to reshape their corneas. This treatment option might allow patients to see clearly without their lenses for long periods of time. Refractive surgery, which changes the shape of the cornea, is an option for those without corneal scars and with overall healthy eyes.
