A common form of astigmatism results when the cornea is elliptical or irregularly shaped rather than spherical. In people with this condition, light that enters the eye is focused on more than one point at the back of the retina. That’s the reason people with astigmatism experience blurred vision. LASIK or Laser-Assisted In Situ Keratomileusis can be used to treat astigmatism since it provides a way to reshape the cornea.

LASIK procedures approved by the FDA for treatment of corneal astigmatism include traditional LASIK or wavefront-guided LASIK (also known as custom LASIK). Traditional LASIK basically involves making a small circular incision in the cornea to create a flap, and using a laser to reshape the underlying corneal tissue. Wavefront-guided LASIK uses a computerized device that shines light in the eye and creates a 3D model of the cornea based on the wavefront of light that bounces back. The computer takes this information uses it to guide the path of the laser during the cornea-reshaping process. Wavefront-guided LASIK is more likely to result in 20/20 vision or better than traditional LASIK. At Western Laser Eye Associates, Dr. Elizabeth Anderson Penno, a board certified ophthalmologist can tell you which procedure is right for you.

While you may not have perfect vision after LASIK astigmatism correction, many people who’ve had LASIK astigmatism correction find that they don’t need glasses anymore. Vision improvement can increase over time, but some report improvement as early as a day or two after a LASIK procedure.
