“Only last few years”

I had only nearsightness -6.25 & -6.0 before my 2 lasik surgeries did 4 years ago. I was nearly perfect after the surgery except my right eye after the surger became -.75 astigmatism. As years go by, my nearsightness comes back, now -.1 & -.75+1.25 astigmatism. I went to get contact lens. But because of the lasik, my eyes become so flat that non of the contact lens will fit me. I am so remorsed and upset that I did the lasik. I have to wear glasses everyday now and no more contact lens. Whenever I have friends want to do it, I will strongly tell them not to. Should I knew that the nearsightness will come back, I would have never done it.
