Today is world #KeratoconusDay. #keratoconus (KC) is an eye disease with no cure. The corneas of those with KC thin and cone out, causing visual ghosting and sensitivity to light. Eye rubbing is thought to be a contributing factor, the direction of the association is not fully understood. Many can be treated with hard contact lenses (scleral lenses), some may be caught early enough for corneal cross linking, which slows or stops the progression, others require a corneal graft. Personally, I was diagnosed late (37) and was not able to get cross linking. I was told I needed a graft but was lucky to find one of the world's leading contact lens fitters and I now get functional vision for around 10 hours a day. My advice to everyone is that if you find your sight deteriorating and glasses are not addressing the problem, and you have been going to an optometrist that does not have the equipment to check your cornea, find one that does. Often the focus is on trying to catch conditions of the retina, which is also very important.
