I had it done pre-pots, although I think I've really had POTS most of my life, just not to this extent. Anyway, my nearsightedness and astigmatism were mild. After the surgery, I had 20/20 vision. But after only a couple of years my vision reverted back to almost what it was before and now that POTS has flared I have double/blurry vision at times as well. Not only that! But I have had to see a specialist who diagnosed me with Vertical Heterophoria and now I must wear my glasses all the time, even to read when I wouldn't normally need them. My vision also continues to change often and rather quickly. Check out www..VSofM.com. My point in telling you all this is just to warn you that us POTSies vision isn't very stable and changes easily. Does your laser surgery place offer a guarantee to adjust your vision later on if necessary? Best wishes! Let us know how it goes ( or how it went ).
