I PRK laser surgery done at Naval Medical Center Portsmouth, VA in November 2001. I had pretty bad myopia (near-sightedness) and astigmatism, and it was corrected to 20/20. Just last month, I had to go back to wearing glasses. A slight amount of astigmatism in the left eye, and mild myopia in both. I was 35 when I had it done, and the docs at the time told me that I would probably have to wear glasses again sometime later in the future, simply due to the natural aging of the eyes.
I would have it done again if I could, because it was worth it to not have to wear the glasses and have good vision. The Navy won't do it again, but I guess I could pay for it this time.
There are several forms of laser eye surgery. PRK, LASIK, and some others that I can't recall. Do the research so that you can have enough information to find out which one is right for you.
