If you dont know what your k readings are, i.e you are not being told at your appointments how do know at what stage your KC is mild-severe?

At what point, i.e K reading does your KC become a "disability" under the Equality Act?

Good question Steven. For a condition that is defined through a variety of measurements - Snellen, dioptres, degrees etc. - it's interesting that some of the objective measurements are less well known than others. I have no idea what my K value is for instance. I've also seen quite a few references to corneal thickness and again I don't know what mine are.

For all the objectiveness that we have on offer for me it's still a mainly subjective impact - am I having a good eye day or a bad one? Do I see huge halos today or just normal ones? And so I'm not sure what additional clarity would be gained by knowing my K value? I imagine that you could have two KC sufferers who have the same K value but have markedly different acuity due to factors such as whether they have nipple, oval or globus (learned something new from your link, thank you), location of the cone etc. etc.

So trying to use just the K value in isolation as an indicator of having a disability or not is unlikely to be helpful - which brings us back to the other thread and the CVI 2007 criteria for certified partial sight.

Such measurement gives an indication of changes in your KC to enable you to know were you are on the scale and they are on record and such data maybe useful for KC medical research and a better understanding of the disease enabling improvements in management - preventative as well as solutions and maybe if we are lucky a cure.

K2 - 51.4d,
