Astigmatism Treatment

An introduction to astigmatism

  • Laser eye surgery is a safe and effective treatment for astigmatism
  • Astigmatism is a common eye condition where a person has an irregular curvature of the cornea.
  • A person’s eye is naturally spherical in shape. Under normal circumstances, when light enters the eye, it refracts evenly, creating a clear view of the object.
  • However, the eye of a person with astigmatism is shaped more like a football or the back of a spoon.
  • For this person, when light enters the eye, the cornea refracts (bends) the light more in one direction than the other, allowing only part of the object to be in focus at one time.
  • Objects at any distance can appear blurry and wavy.

How astigmatism symptoms can impact your life

Astigmatism can significantly affect how you perceive the world.

Symptoms of astigmatism include:

  • Blurry, distorted, or fuzzy vision up close, far away and in between
  • Difficulty seeing at night
  • Eyestrain
  • Squinting
  • Eye irritation
  • Headaches

These astigmatism symptoms can have profound negative effects on your lifestyle, depending on how you use your eyes. Fortunately, you can correct the effects of astigmatism with corrective lenses or permanently correct astigmatism with laser vision correction.

Don’t feel overly concerned about astigmatism

Instead, think of astigmatism as just one of the many beautiful and infinite differences we see in all of us. Some of us have longer than average arms and legs, some of us have shorter than average arms and legs. This variety in nature includes the shape and size of our eyes.

You’re more at risk for astigmatism if you have:

  • A family history of astigmatism
  • Scarring or thinning of your cornea
  • Excessive nearsightedness
  • Excessive farsightedness

There is no way you can prevent astigmatism from developing.

Causes of astigmatism

Causes of astigmatism

Like a basketball a healthy and normal eye is spherical. When your eye is more oval shaped (like a football) – you’ve got astigmatism. That means that the curvature of the cornea (the transparent covering at the front of the eye) is not the same vertically as it is horizontally.

When light enters the eye, the eye focuses light on two different planes rather than at a single point. Images appear blurred or distorted, and you may experience ‘ghosting’ or ‘double-vision’. The picture below illustrates how light focuses on the retina of a healthy eye versus an eye with astigmatism.

You can have an astigmatism examination in Toronto

An ophthalmologist (eye surgeon) or optometrist (eye doctor) can diagnose astigmatism by conducting a comprehensive eye exam that includes:

  • A visual acuity assessment test – reading letters from a chart at a specific distance to see how well you can read the letters
  • A refraction test – a machine that performs a similar job as we describe above
  • Keratometry – a device that an eye doctor or surgeon can use to measure the curvature of your cornea
  • Sometimes, severe forms of astigmatism can develop into disease states, like keratoconus

Keratoconus is a severe and progressive condition, so if you find your astigmatism worsening, it’s imperative that you get an eye exam at your earliest opportunity. If you think you have astigmatism and wish to discuss surgical treatment, contact us.

Astigmatism treatment details

Glasses and toric contact lenses are temporary solutions to correct astigmatism. People have a common misconception that laser eye surgery cannot correct astigmatism. This is wrong. Laser eye surgeons can use any of the following procedures to permanently cure astigmatism.
