What Is Astigmatism?

Astigmatism refers to an irregular curvature of the cornea, the clear outer covering of the eye, which results in blurry vision.

 

The normal cornea directs light rays into the eye and accurately focuses them on the retina, which is the light-sensitive layer at the back of the eye. However, in the case of astigmatism, the corneal surface becomes irregular, causing the light rays to focus improperly on the retina.

 

Thankfully, vision issues caused by astigmatism can be effectively managed through various means, including the use of eyeglasses, contact lenses, surgical procedures, and Toric IOLs.
