UK Keratoconus Self-Help and Support Association

Can anyone suggest any good private doctors/surgeons for getting CXL .......C3R in London . Who can perform it for cornea less than 400.

I was in the view that it can be only done for more than 400 thickness , but i have seen the DVD and its possible and also someone has got it done in Swansea for less than 400. (Which is big news for me as opticion told me in its not possible,)

There are some special drops used .

Please help.

Thanks
