Are there cases where lens replacement is necessary after phakic IOL surgery?

I saw a post about lens exchange surgery and I'm wondering if it's a common situation.

Is lens exchange considered when the lens size doesn't fit or when there's a change in vision?

The fact that lens exchange surgery is possible might be an advantage, but undergoing surgery again feels burdensome.

It's crucial to get the lens size precisely measured during the initial examination, right? ㅠㅠ

Has anyone asked about the possibility of lens exchange during their consultation for lens implantation surgery?
