What is Astigmatism?

Astigmatism is quite a common eye condition that causes blurriness of vision. It’s one of several Refractive Errors of the eye, and it can be corrected with laser eye surgery.


The cornea is the clear part at the front of the eye and it is usually round, like a sphere. Light enters the eye and is bent or refracted evenly, to create a clear image on the retina at the back of the eye so we can see well.


However, in people who have astigmatism, their corneas are not round – they are shaped more like a rugby ball and are not a perfect sphere.


This means the light entering the eye does not get bent or refracted evenly. Instead, light gets refracted a bit more in one direction than the other, so not everything is in focus at the same time, and objects at any distance can appear blurry.


Astigmatism is an eye condition that causes blurred vision.
Laser Eye Surgery can correct this condition in minutes.




This is because the light is hitting the back of the eye at multiple points, instead of at a single point on the retina. Blurriness and eye strain or eye fatigue are the most common symptoms of astigmatism as your eye constantly battles to keep objects in focus. The condition can be accompanied by myopia (shortsightedness) or hyperopia (farsightedness), both of which are also refractive errors.




Solutions to Astigmatism


Astigmatism affects many people to some degree; the exact cause is unknown but it is easy to address. Glasses and contact lenses will provide a temporary solution when they are worn, but laser eye surgery offers a more permanent, convenient and effective solution.


Laser eye surgery swiftly and painlessly corrects the curve of the cornea by reshaping it with a laser to make it rounder. This is called refractive surgery and it will allow the cornea to bend light more evenly so that a clear image can be formed without the need for corrective eyewear.


If you have either myopia or hyperopia as well as astigmatism, both conditions can be treated in the same laser eye surgery.
