First of all before we came along, things was not moving at all, with just talk of corneal transplants and contact lenses, since out arrival so much has changed, with treatments that where just ticking along, hidden from view being uncovered and helping so many people, look at Valeri, at one point he needed a Rose K lens (so he had advanced kc), he only needs to wear glasses now to be corrected to 20/20.
Hari your another fine example, you need no correction, it goes to show the few "professionals" that we met in the past, will be eating their own words as they where wrong about so much.
