Lasik doesn't guarantee 20/20.

The maximum time would be forever. LASIK surgery cannot guarantee 20/20 without glasses, some people do not achieve that level.

One thing you should consider is that if you're having it done to correct nearsightedness, remember that when you get into your forties, you will need reading glasses. This is why I will never get this procedure done. I already am in my 40s and my close up vision is still very good. This is a characteristic of being nearsighted. Normally, people develop a type of farsightedness when they get older. I have not. The only time I have a problem is when I'm wearing my contact lenses. Then I can't see close up very well and need reading glasses. Otherwise, it's quite odd to see a middle-aged person taking off the glasses to read or look at something close up like I do. Most people my age put on glasses for those reasons.

Both the above are correct but, in addition, the eyes should normally be allowed three months before the result is considered "final" especially if the refraction has not come out as near zero as hoped and a top-up procedure is being considered.
In a small minority of cases the poorer vision is due to corneal problems: oedema, infection, infiltration of epithelial cells. These need to be looked for, and dealt with if necessary, at one or more follow-up visits.

I don't think you could be given an exact time considering some of the problems listed below-
Some patients lose vision.
Some patients develop debilitating visual symptoms.
You may be under treated or over treated.
Some patients may develop severe dry eye syndrome.
Results are generally not as good in patients with very large refractive errors of any type.
For some farsighted patients, results may diminish with age.

Your eyes should be immediately better. AA little blurriness post-surgery is normal but should be gone within 4-6 hours (as soon as the numbness wears off).
