I did my femto-lasik recently, thanks jialat
So far so good, my left eye was around - 8.0 and my right was around - 11.0.
Now my both of them are about 0 with some left over astigmatism( I had high astig previously around 3-3.5 iirc for both eyes).
Overall, I'm satisfied with the outcome. The only complication I have faced so far is dry eyes which is common. I would recommend you to do a full eye examination before you make a decision. I was told that if you possess a high power, your eye power "could" change after lasik
