I used this guy
http://www.cvi2020.com/ Clavenna did mine, my wife used his partner Fitzgerald.
I had it done in my mid 40's... and yes it still regresses. I've actually lost my sight in both eyes and had so many surgery's... so I no longer can attest to the benefit.
Several things they tend to not tell you.
Most will give you free "touch ups" if it regresses in the first year.... you really need this to be life time.... but, if the "flap" they cut seals to tightly in some cases (like in 6+ years) they can not go back and give you the touch up. Your done.
Also, they are working on a process using 3 rings of cut. This will give you perfect distance mid range AND close up.... how ever its not approved yet. Check with your Dr and see when this new process will be available. I would want this.
Also, don't care who you are-every one need bifocals after a certain age. By 50 you most likely will need them. (Unless this new 3 ring process eliminates the need.... not sure, I think it does)
In most cases, the sight you have 24 hrs after surgery will be like superman (at least it was for me) Colors look more brilliant, fantastic detail..... I was amazed. I would not hesitate to have it done. My original vision was like 20-200 or worse.
