They probably just mean in terms of reversability; LASIK is obviously permanent, but ICL can be undone.
Both procedures are relatively low risk; each has their own set of drawbacks and qualifying conditions (eg - ICL isn't recommended for people who are over 45 years old).
45 years old is bizarre FDA restriction rationalizing that you might need lens replacement or +glasses soon anyway. Other countries don’t have this limit for ICL.
There are a lot of 45-year olds that won’t need RLE until 65, if ever. Why do they need to travel to Mexico to get ICL instead of doing it in US? Same thing with modern multi-focal RLE lenses. They got approved in US just couple years ago, and people used to go to Tijuana just to get access to them for years before that.
