I don't recall ever hearing about a connection between kidney donation and eye infections, but I'll share these ideas in case they might be of any help:
--- some doctors recommend that kidney donors take supplements of Vitamins b-12 and D (even if you get sunshine) as we seem to develop deficiencies in these. But I have never heard of eye infections being a symptom of such deficiencies.
--- staying properly hydrated is important for kidney donors. Might dehydration lead to dry eyes leading to more infection? I have no idea, but being careful about hydration certainly would not hurt.
Sorry I can't help more. Please let us know if you find out anything.
By the way, you might want to also post your question at the FACEBOOK page of Living Donors On Line as many more donors check the postings there.
