Astigmatism FAQs with Your Phoenix Ophthalmologist

Much like nearsightedness and farsightedness, astigmatism is a condition that causes the light entering the eye to not focus correctly. Instead of vision being blurred far away or up close, it's hard to focus on objects at any distance. At Eye Doctors of Arizona we have patients with astigmatism, often combined with farsightedness or nearsightedness. Many of our patients have never heard of astigmatism when they get find out they have it, and they naturally have questions. Here are some of the most common ones:

How Does Astigmatism Happen?

Most eyeballs are round, like a basketball, allowing light to hit all parts of the inner surface at the same angle. With astigmatism, the eye is misshapen, more like a football. It measures longer in one direction than another, making light have to travel farther which causes blurring.

What Are Symptoms of Astigmatism?

For most people, the most significant symptom is blurred vision in all distances. They might also suffer from eyestrain, headaches, or fatigue.

How Common is Astigmatism?

Almost everyone has at least some small degree of astigmatism, but most people don't have it badly enough to affect their eyesight. Only those with moderate to severe astigmatism will need corrective treatment.

How Can I Find Out if I Have Astigmatism?

When you come in for your regular comprehensive eye examination, our optometrist can tell if you have astigmatism. It's very simple to diagnose in our office, and can be treated simply once discovered.

How is Astigmatism Treated?

There are a wide variety of treatments for astigmatism. Most people opt for corrective eyeglasses or contact lenses. An increasing number of our patients choose to undergo LASIK surgery to correct the shape of the cornea, which is the problem causing the blurred vision. We also offer orthokeratology, or Ortho-K, treatments, which use a series of rigid contact lenses that are worn at night. These lenses reshape the eyes while you sleep, giving clear vision for up to 48 hours. When you're diagnosed with astigmatism, you and the optometrist will consult to discover the best treatment option for you.
