:) Yes, they did, Nosha. The effects are instant, if a little blurry, which is why they tell you to take someone with you when you go.
They give you lots of drops to use afterwards to prevent infection, etc, so you might need someone to help you with those, too. You have to go back to the clinic the day after, then a week after that, a month after that, and then I think it's three months after that until the anniversary of the surgery. The aftercare they both received was excellent. :)
