I had it done 5 and a half years ago and my vision has remained great ever since. My vision was around -4.5 when i had it done and i had both eyes done at once (some people are scared and do one eye at a time). It's the best money i ever spent. After i had it done i used to go to the bathroom each night to take my contacts out... I kept forgetting that i wasn't wearing them anymore
It's great to be able to dive into water and keep my eyes open and not worry about losing a contact lense, go to the beach for a swim and be able to see where you left your towel, not have to take solutions and saline for contacts with me each time i go away, i can be lazy and fall asleep and not worry about did i take my contacts out?, not having to constantly clean glasses, getting rain drops on glasses and red marks on my nose from glasses, always having to update glasses and contacts.
I have never taken my eyes sight for granted since having it corrected b/c it was almost like being blind and having somebody perform a miracle and giving you your sight back
