I had LASIK in 2000, no issues, my vision has drifted back to 20/30 but I can at least find my glasses over the 20/800 it used to be.
My experience is similar but with a little more drift over time. LASIK in Toronto in '98/'99; prescription before LASIK was -8.5/-6.5. My goal was to be able to function in an emergency without glasses and I can still do that, but am up to almost a 2 diopter correction in one eye for distance now. But can still read a newspaper easily with no reading glasses. My only complaint about side effects from LASIK is that low-contrast/low light vision was impacted negatively (due, presumably, to additional glare occurring at the ablation surfaces within the eye). My feeling is my vision is overall quite good now compared to most other 55+ individuals.
