Laser Eye Surgery for Astigmatism; No More Blurry Vision
Can I have laser eye surgery if I have astigmatism? The short answer is Yes.
You probably have heard about laser treatments for people who suffer from both near and farsightedness. Fortunately, laser eye surgery is also an effective, quick, and painless procedure to correct astigmatism. So, if you’re tired of using glasses or contact lenses, this surgery offers a great and permanent solution to fix blurry vision.
WHAT IS ASTIGMATISM?
Astigmatism is a common vision refraction problem where the lens of the eye, known as the cornea, has an irregular curve. So your eye is more shaped like a rugby ball (egg-shaped) rather than a football.
This curvature changes the way light rays enter the eye and refract (bend and focus) in your retina, the light-sensitive layer at the back of your eye. With astigmatism, one meridian is significantly more curved than the meridian perpendicular to it. So there is an irregularity both depth-ways and sideways.
To understand the concept of meridians, think of the front of the eye (cornea) like the face of a clock. The line connecting the 12 and 6 is one meridian, and the line connecting the 3 and 9 is the other.
In patients with astigmatism, one meridian is significantly more curved than the other perpendicular to it. Hence, astigmatism provides two focal points instead of one.
This means you can only partially focus on an object, having blurred vision to some degree at all distances, both near and far.
