For some with a terrible astig, lasik may only do so much. I was in shortstrokes catagory with an astig. To make matters worse, the front of my eyes were basically flat, as opposed to a more simple astig.
So, the lasik dr's warned me that I still may need glasses if I did the lasik. I did the lasik anyway and pretty much what the dr's said was the result.
I'm 20/25 in the left eye and closer to 20/35 in the right. I can now function greatly without glasses. I can now do normal things like shave, see an alarm clock, watch tv, etc, without glasses. I would also feel comfortable driving during the day without glasses. And all that is very sweet and life altering. Before, my vision was so bad that a magazine cover was a blurred blob at arms length.
However, for hunting and shooting, I still need glasses after lasik.
I realize that my vision was terrible and I was a borderline candidate for lasik. But if you're 20/400 plus and have any flatness on the front of the eye, don't always expect crystal clear 20/15 hawk vision if you do lasik. It's possible that 20/25-20/30 is what you may get and then if you want hawk life vision for hunting, you still may be wearing glasses.
It's great for regular life stuff, but if your case is extreme like mine, just realize that you still may require glasses for hunting.
