Signs of rejection of a corneal graft
Remember the acronym "RSVP":
R - Redness. If the white of the eye is suddenly bright red, or even just noticeably pink, this could be a rejection episode starting. Sure, it could "just" be conjunctivitis, but it's better to be safe...
S - Sensitivity to Light. Many of us are photophobic to a degree, but any sudden increase in sensitivity is another sign of rejection.
V - Vision change. If you can't see when you wake up - even after putting the specs on, or the contacts in; and you could yesterday then that's a classic early warning that something is changing in your eye. And that is probably not good.
P - Pain. This one speaks for itself. If your grafted eye hurts, get it checked out ASAP. In my experience (7 rejection episodes) the only pain I felt was when I accidentally instilled a drop of Miraflow cleaner into the eye. Thankfully, that didn't cause a rejection, but it was worth getting it checked out anyway.
In all of the above cases, get yourself to your local eye casualty unit as soon as possible. If you don't have a local eye casualty, then go to your nearest A&E unit. I've found that telling the triage nurse that you've had a graft and you're suspecting rejection tends to ensure that your time in the waiting room is mercifully short!
