I think it really depends on your prescrition, how well the surgery can correct your vision, I know people who have had high astigmatism, and needed glasses again a few years later to correct it again.
Unless you were considering having eye surgery anyway, rather than having it done just for your wedding day, I would say go for it, if not, I would just get fitted with some soft contact lenses, you will have plentyy of time to practise getting them in and out.
If your a bit squeamish , its not a great procedure, as your awake and having to think about what they are doind, even if it doesn't hurt!
I work in a opticians by the way
