I had LASIK myself in 1999, back when there were no safer alternatives, and we did not have wavefront treatments, and the laser treatment diameters (optical zones) were very small. Therefore, everyone done in the 1990s has poor night vision.
You can do a surface ablation after LASEK to increase your optical zone, to go wider, since lasers today go wider. Unfortunately, you choose to have a PRK, which is an archaic way to do a surface ablation. I performed my last PRK in 1999. The modern version of PRK is ASA, which is Advanced Surface Ablation, the Advanced part meaning more advanced than PRK, which is either LASEK or epiLASEK.
I don't know if you had a CustomVue WaveFront HD enhancement--if you didn't, you should have, in order to reduce your starbursts. You should have a PreVue lens, so you can assess now how the HD treatment can get rid of this. I wrote a letter to the editor of a prominent refractive journal 3 years ago, about how surgeons under-utilize PreVue lens techniques (most eye surgeons don't even know this exists, because they never did a fellowship in refractive surgery).
Anyway, if I were you, I would have a PreVue lens done to see if another enhancement would fix your problems, and then have an ASA procedure, NOT PRK. Hope this helps, and people are flying to Park Avenue LASEK from all over the world, because we are the only center in the world exclusively dedicated to and specialized in ASA (therefore, we should know what we are doing better than anyone else, since we do ASA 100% of the time, and other centers do that 1-10% of the time.
Hope this helps, and if you don't want more surgery, try alphagan prn qhs (your surgeon can write the Rx).
