Astigmatism

Astigmatism

Astigmatism occurs when the eyeball or cornea is abnormally shaped – like a rugby ball as opposed to a football.

This abnormal curvature means that the cornea has different measurements horizontally and vertically. As a result, light entering the eye is focused at two separate planes, rather than at a single point on the retina.

These multiple planes of focus can cause the images being sent to the brain to appear blurry or distorted. Some individuals with astigmatism may also experience “ghosting” – a kind of double vision.

Around half of people with myopia or hyperopia also have some degree of astigmatism.

Laser Eye Surgery can be effective at correcting astigmatism, whether it occurs alone or alongside myopia or hyperopia.
