Astigmatism -
In the normal eye, light enters through the cornea (the
clear front surface of the eye) and comes to a focus on
the retina in the back of the eye. Astigmatism occurs
when the cornea is not spherical in shape (like a
baseball) and instead is longer in one direction (like a
football). This causes the light to focus in more than
one place within the eye, causing your vision to be
distorted or blurred. Astigmatism is often responsible
for starbursts, "ghosting" images, and halos or rings
around lights at night.
Astigmatism is usually corrected with glasses or contact
lenses but it can also be corrected surgically with
LASIK, PRK, or Limbal Relaxing Incisions.
