I was diagnosed with KC in 2006 by a hospital eye specialist.
After the first tests, it was left to be monitored for 1 year.
A year later I returned, had all the tests and told it had not progressed
so was discharged and told to see my optician yearly.
I visited my optician yesterday, and after testing my eyes and seeing the
results, was very surprised that the specialist never mentioned RGP lenses
as my eyesight was worsened dramatically.
He advised to make an appointment with the hospital optician and request RGP lenses as KC could be reduced as the eye would shape into the mould of the lens.
Is this correct? Or is the lens only used for sight? Currently I can get by without anything, and my left eye is fine for now, but slowly deteriorating. I cannot wear the correct prescription glasses and they cause headaches. Would anyone recommend pushing to get RGP lenses after I was discharged by the specialist? The optician seems to think so!

Many years ago I was also told by my optometrist that the RGP would 'flatten' the curvature and therefore improve the KC. But I understand now that this is not generally accepted as true.
There is very little/ no proof that wearing RGPs improves your KC- in fact they bring more risks in terms of the irritations and scars.
RGPs are very useful to correct the vision though, and are therefore very important to people with KC.
I would say that if your vision is acceptable without RGPs, then do without them- they are hard to get used to and if you can cope without them it is not neccessary.
The trick is knowing what vision is acceptable for you. you shouldn't be having headaches and eye strain.
