Tomorrow marks my four year anniversary with ICLs. Four years later, I'm still 20/20 with no major issues to speak of. The halo problem persists, but I really don't think about them much any more. I don't use the anti-halo drops at all these days. Some nights, the halos are barely there and the next night they'll be worse than ever. Their impact on my quality of life is minimal.
Now having gone four years without contact lenses or glasses, it's almost like I can't remember what that was like, and how much of a hassle it was. I love being free of those things! I love seeing the alarm clock in the middle of the night, even if there is a halo around it. ;)
If you're considering ICL, really think about pros vs cons, and accept that there are likely to be cons. It's amazing to think about going from total nearsightedness to 20/20 in a couple days' time. That kind of magic has to have a price with it, and apparently my price was a few halos. I'm happy to have paid it and enjoy my clear vision.
