Hallo Sebastian and welcome to the foru.
I well understand your concerns, and wish you luck.
Are you allowed to fly in contacts these days, without having to have glasses handy to put on if a lens pops out? - if so, that's an improvement from KC-er's poit of view.
Hope you get hte lenses sorted out soon.

Sebastian,

If C3R halts the progression of KC, your existing lens may well be fine. If it regresses the KC which it has in many cases, never cured it, you may well be able to revrt to glasses and avoid the lens issues.

Unfortunatly the only way to know is to have the treatment, impossible to make anysort of prediction with KC.

Ok so I went to my eye doctor and he said the fittment is good, but he did order a new pair for me that has a bigger diamater(1ml bigger is what I think he said). Does anyone know what advantages does a bigger diamater have in a RGP lens ? also here is the link to doctor I see.

Gee you are up early! LOL!!

It should make a better fit according to the shape of your cornea. Being slightly bigger will hopefully sit nicer on a steep cone and your eyelids would be able to pass over it better. Also this is sometimes used to cover any dry areas or sore spots so that they aren't constantly rubbed by blinking. Mine is slightly bigger for this reason so that the two dry areas don't get rubbed so often.

Hoping it works out for you!

I guess that it probably does. But this is no different from the experience of people with KC who have never had C3R. Our cones progress, so that we need constantly to have lenses re-fitted.

Sebastian,

The larger diameter may also mean the rim of the lens now sits under the eye lid margins, so when you blink the lids just slide over rather than pushing the lens before sliding over the lens.

Might reduce the movement somewhat. I know many optoms refer to fit as how the lens sits over the cone and touches the cornea. Others take fit to mean this and how the eye lids move over the lens.

What looks good at first fitting may need tweeking at a check up as in your case. Keep the cone fit the same, but opush the rim out a bit further.

Gareth and Sweet provided a very good summary of the larger diameter lens!...Comfort will more than likely be better; however I would suspect that you may need a few referals back to the fitter....as one issue with the larger diameter; and even Intra-lymbal lenses; is that if the fitting is not correct; the bearing on the central parts of the cone can be excessive over periods of time (hours of wear) and may give a dull pain......however...as always; if you are with a experienced CL fitter....these issues may no longer be issues

A question: Is there a difference in wear time between larger and smaller lenses?

[GarethB]

My left eye has a larger lens and the wear time is much higher than the right with the smaller lens
