It is supposed to be able to correct my astigmatism. However, it tends to heal unevenly so you can experience astigmatism (or astigmatism-type symptoms) during that process. I guess we won't know for another few months what is actually causing my double vision. It's most likely due to the corneal edema and dry eyes (I know that sounds like a contradiction). It COULD be caused by an uncorrected astigmatism (that I had previously) or it could be due to a new astigmatism caused by the procedure. My initial suggestion is the most common. I am tired of typing 'astigmatism' now.

I had PRK by the way... (3 weeks ago).
