Tom > My other avocation is astronomy, and I have read about laser surgery causing rings around bright objects at night. I asked a very good eye surgeon about this. He explained that typical laser surgery only corrects the central portion of the cornea. He said that when your pupil dilates at night you use the outer rim area, and this remains uncorrected, hence the ring effect. He said he could cut the cornea, lift it up, do a correction to the edge, and stitch it back. I said no thanks.
