Sounds like astigmatism, which I also have. I don't know if this procedure, unlike LASIK, can correct astigmatism. I know you said you weren't interested, but for me personally, wearing contacts (not glasses) completely fixes my astigmatism and makes it much easier to drive at night.
Source: Had LASIK in 1999. Severe myopia and astigmatism, corrected to 20/10 and 20/15 (right and left eye).
My night vision was definitely worse after the surgery, but improved over a year or two. I still get blurry when my eyes are dry and tired, but otherwise remain glasses-free at 50+.
That's when I had my eyes done but not for astigmatism. Have you noticed your eyes getting drier lately? Mine started a couple of years ago and it's somewhat of an issue now having to keep drops around.
Contacts for astigmatism have a tiny weight on one side which keeps them oriented (enough) that they can cancel out mild to moderate asphericity.
I'm surprised LASIK still can't correct for astigmatism though, I know that was the case when it first came out but in principle I can't see why it wouldn't work.
