What is Astigmatism?

What is Astigmatism?—Is it serious?

Astigmatism does sound serious or scary to some people but it is simply that the shape of the

eye is not a sphere. It is shaped more like an egg. Unlike nearsightedness or farsightedness

(which the light comes to focus before or after it hits the back of the eye), astigmatism causes

light to come to multiple focuses in the eye.

Astigmatism is very common. As many as 75% of people have some degree of astigmatism.

Symptoms of astigmatism are an inability to focus at any distance, distortion of vision and eye

strain, It can be detected by your eye doctor during a routine eye exam.

Astigmatism has to be corrected with a lens or surgery. The type of lens that corrects

astigmatism is called a “toric” lens. Toric lenses can be made into glasses, contact lens or a lens

that is implanted into the eye. The eye can be reshaped with LASIK or other types of laser


At the time of cataract surgery or dysfunctional lens surgery, an toric implant may be placed to

give the best focus for the eye. Patients are usually very happy with the quality of vision with

these implants.
