Hope you are all doing ok with this neverending winter-time

My son has KC and has an appointment in March (his first one) to see a consultant at Queens Medical Centre Nottingham about it.
He has asked me to go with him as he feels fazed in medical scenarios and I'm not afraid to ask questions

I've read lots on here and other places about KC and there certainly is a lot I could ask. To help me filter down to the key important things for a first appointment, I wonder if you are able to inform my thinking on this please?
With the benefit of hindsight, what in your opinion are the most useful/helpful key questions I should be asking at this first appointment? For instance, should we be enquiring what thickness his corneas are?
I'd be really interested to know what your views are if you have a minute to share.....Thankyou. Julia
