Eye drops sounds yucks, but I know you trust your dumpy a lot, so maybe it will be okay if he gives thems to you. Mama had to give the fuzzy pig ear drops a while ago and he was a squirmy little wriggler!
Mama says to say she did a search for "ulcerated cornea" and saw that it isn't very serious, so that sounds good Trix! You will be all betters in no time, we are sure.
