For LASIK, my advice is 2-3 checks with your eye clinic after you have done your LASIK. If you are happy with your vision and are still seeing clearly, you do not have to go back on an annual basis. If you feel that your eyesight is regressing, you can just visit an optician.
However, for ICL, you should do a follow-up every 1-2 years to check if the implant fits your eye.
