Astigmatism

Astigmatism

Astigmatism is a vision condition that causes blurred vision due to an irregularly shaped cornea, the clear front cover of the eye, and changes in curvature of the crystalline lens inside the eye.

In an Astigmatic eye, the cornea or the crystalline lenses are not smooth or evenly curved thus focusing the light irregularly at different regions of the retina. If the cornea is not evenly curved it’s called corneal Astigmatism and if the lenses are not curved regularly, it is called lenticular astigmatism.

In both the conditions the vision would be blurry and distorted for both distant and near objects.

Astigmatism Correction

• Eyeglasses: This is the most popular correction method for Astigmatism and these eyeglasses have a special cylindrical lens prescription that corrects Astigmatism.
• Contact Lenses: Some people with an active lifestyle prefer Astigmatism correction with contact lenses. Contact lenses may provide clear vision and a wider field of view. Special toric soft contact lenses can correct many types of Astigmatism.
• Laser Surgery: Astigmatism can also be corrected by reshaping the cornea through LASIK (laser in situ keratomileusis) surgery.
