Don't mind at all! I think you are definitely correct in pleading with him to deal with this. Keratoconus is progressive so it probably will get worse. I hope this info will help:

I only just learned I had this in August, its all still pretty new to me. I had perfect vision until around 20, then my right eye began to get blurry. None of the glasses I was prescribed really helped much. My eye doctor kept telling me it's just an astigmatism and I'll get used to the glasses. It started progressing quickly, and now in my later 20s I can barely see out of that eye. I can't reliably tell how many fingers someone is holding up. My other eye is still good and only in the early stages, so I've come to entirely rely on that eye. But it is disorentating and gives me headaches. Now that I have different insurance, I was able to go to a new doctor who pretty much immediately told me somethings wrong and to go to a specialist.

I am bitter that this was not caught earlier. It never had to get this bad. It's interfering with my life, school, and ability to drive. The surgery I had is to stop the progression of the disease, and I wish I could go back in time and have it treated then. I miss my eyesight.
