No specific age related risks that I've heard about. I had LASIK just over two months ago at age 41 without any problems. But everyone is different and the only way to know for certain is to go for a consultation.
One thing to note tho, LASIK doesn't correct for age-related nearsightedness -the kind when you need reading glasses. That's eye muscle related and not affected by the resurfacing of the cornea that is done by LASIK.
I had pretty bad vision (-6.5 and -5.75). Now I am better that 20-20. It's miraculous!!
