Question: What part of the eye is shaped differently for people with astigmatism?

What part of the eye is deformed in an astigmatism patient?

It occurs when the cornea (the clear front cover of the eye) is irregularly shaped or sometimes because of the curvature of the lens inside the eye.

Do people with astigmatism have different shaped eyes?
