I had CK treatment in October 2003. I was surprised that the treatment was completly painless. My eyes have steadily improved since then and Mr.Allamby tells me I now have 20/20 vision! Not bad for a 60 year-old!! I have never worn glasses since having the treatment and tell all my friends about it. I would thoroughly recommend the procedure to anyone who is fed up with constantly having to bring out spectacles for reading menus etc.
