Expecting to have both eyes done I was surprised to find I was advise to have only one eye done. This meant considerably less cost and more years where I wouldn't require reading glasses - I am 40+ and at that age where most people start needing reading glasses. If you are wondering about pain then don't, its just a little discomfort both during the surgery and in the post op. period. The impact to my vision was almost perfect immediately and as it settles down it only gets better. My life without glasses (actually I was regularly without as I was always losing them!!!) is fantastic as we can now leave the house now without the family going on the great "where has dad left his glasses" hunt. Great clinic and fantasic people - can't recommend FOCUS highly enough.
