WHAT IS ASTIGMATISM?

Astigmatism is a finding that refers to the CURVATURE OF THE CORNEA (clear front part of the eye). In most cases you are born with astigmatism. It is very common. 

We divide the cornea into a vertical and horizontal axis.

When each axis focuses light equally, there is NO astigmatism and the cornea is considered to be spherical (or circular)

"Not sharp" vision

Shadowing of images

Haloes or starbursts around lights

Can we correct astigmatism at the time of cataract surgery? ​​

Laser cataract surgery corrects most common levels of astigmatism

Toric intraocular lenses (IOLs) correct higher levels of astigmatism 

These techniques are NOT covered by Medicare or commercial insurance plans.
