Mine were done in 2003, a week part.
I couldn't see red, a serious problem when half my appointments were at night. I still wear glasses to see anything inside 20 inches, but it's a marvelous change for 20/200 right, and 20/ 250 left, and cataracts to boot.
A side benefit is like an old detergent commercial: my "whites are whiter and my brights are brighter", and I see everything about 50% bigger.
The procedure has improved a lot over the years
