https://www.reddit.com/r/Keratoconus/ -- but do not freak out, most cases are completely treatable with scleral contact lenses, social media bubbles up the outliers. Next step is ophthalmologist, ask for a corneal topography (photograph and measure the surface shape of your eye w/ a computer) to establish a baseline and monitor for progression. Not all ophthalmologist offices have the corneal topography machine so ask for that on the phone. https://en.wikipedia.org/wiki/Corneal_topography To get a KC diagnosis they will likely want to see progression over time in these topography readings. You want to get this sorted while you are young, the corneal cross-linking procedure will halt the progression of the disease and "lock in" your current vision. I did not get the CXL procedure when I was young (it was still experimental back then) and regret it, my vision is fine with correction but the scleral lenses are a pain and it's unclear if i'll be able to read in bed without lenses in my old age.
