Is LASIK possible for high myopia?

The cornea is relatively thin, and I have high myopia..ㅜㅜ

It is -7.0, -6.0.

They recommend LASIK because the cornea is thin.

Another hospital said they do not recommend LASIK for high myopia.

I need to undergo a detailed examination again, but I want to think about it in advance, so I'm asking!
