I have keratoconus too and I wear hard lenses as the OP. While they are indeed inconvenient (we could write an article only about that, right), I make the daily effort to support them - unless it's an allergy day then lol no way. I never heard of CXL until now, so I'll have to look into it, thank you for the hint! Maybe the docs never mentioned it to me also because my numbers are stable for the last fifteen years...
