The eye clinic which initially diagnosed me with astigmatism a year back, now says I most probably have Keratoconus. The prognosis looks gloomy . The only long term treatment seems to be a cornea transplant. I think the eye clinic should have diagnosed this earlier. I've fixed an appointment with a cornea specialist tomorrow to confirm it. I hope it's still in the early stage. You never know how valuable vision is, until there's some trouble.
