The dreaded "Astigmatism"
Years ago, the correction of astigmatism was one of the greatest hurdles to a terrific LASIK result. Now, with amazing advances in laser mapping and technology, astigmatism has become a routine treatment. Patients, however, love to talk about their astigmatism as if it were some dreaded disease(like "Rheumatism")! Nothing could be further from the truth.

Astigmatism is not a Disease
Astigmatism is not a disease, but more nearsightedness or farsightedness in one meridian or "axis" than the opposite 90 degrees.

LASIK vs LASEK for astigmatism
If you have a low to moderate amount of astigmatism, either LASIK or LASEK can successfully eliminate that. I know this personally as both a surgeon and patient, as I had 1.50 diopters of astigmatism before my LASIK in 1999, and got rid of it totally (although I needed to be "double-carded" or my myopia shot first, then another treatment card inserted into the laser to treat my astigmatism, because this was so long ago it was before FDA approved the COMBINED treatment of myopia...

LASIK for astigmatism
Patients are delighted to find out that LASIK doesn't only address their nearsightedness and farsightedness, but it can correct relatively high levels of astigmatism as well. Set up a consultation with your eye doctor to make sure your degree of astigmatism isn't beyond the approved FDA treatment range. All the best!

Astigmatism correction with LASIK & PRK
Yes, LASIK & PRK, especially Wavefront-guided treatments, can correct astigmatism and make the vision better. The is a limit to the amount of astigmatism the laser can treat; but, most average amounts of astigmatism can easily be treated.
