When i went for my initial Class 1, I was told I had Keratoconus however i still got my Class 1. That was when I was 17. A year later, I went through collagen cross-linking (CXL), and my medical was suspended for 6 months (as it used to be back then). Now, aged 24, I'll be undergoing CXL for my right eye, and my AME has said there's no issues, just grounded for 3 months! I fly commercially, so that gets me off work for 3 months....winner!
You should have no issues, just keep your AME informed at all times. Good luck!
