Fellow keratoconus sufferer here. Glad to hear about your successful treatment and spontaneous improvement. I definitely notice day-to-day differences in my acuity but nothing miraculous like that. Hope it remains good for you.

I "missed" corneal collagen crosslinking w/ riboflavin (the treatment I assume you're eluding in your paragraph re: soaking your cornea and applying lasers). When I was initially diagnosed the treatment was in trials outside the US. By the time it was approved in the US my corneal specialist said I'd "stabilized" and was likely to see no benefit for the procedure, only risk. My prescription has been reasonably stable for the last 10 years (at least as far as my astigmatism and keratoconus goes). Now I'm just descending into presbyopia hell.

Out of curiosity, do you have a history of allergies with ocular symptoms (itching, swelling)?
