Hi Pauline, I know that you are just about to go for the op, however, have your tried scleral lenses yet? These are the ones that cover your whole eye and are much more comfortable than rgp corneals.
I had worn corneals for over 25 years when my eyes just decided that enough was enough and they would not tolerate them any more. Like you, I thought that I would have to have the op, but luckily I was offered scleral lenses and these have been just great. That was over 6 years ago now and I wear my sclerals for 12-16 hours every day. They do not give me quite as good vision as with the corneals because they don't actually touch the cornea, but this is corrected with glasses which I wear for driving/reading/pc work etc. The rest of the time I do not need the specs.
Sclerals are an option when people are having problems tolerating corneals or the cone maybe too big and the corneals keep falling out. Sclerals CANNOT fall out! (KCers often end up wearing them post-graft too). They are very comfortable and no dust/grit can get behind them - I often wish I had been offered them years' ago so at least I could have given my eyes a rest from the corneals, but hey, at least they have kept me off the operating table.
There is info on sclerals on the KC website but if you want to know anything else, please email me on

Whatever you decide must be the right decision for you as KC is unique to each individual, but I just thought sclerals were worth mentioning as you seemed in two minds. Hope everything goes well and keep us posted.
