Sorry to hear about your fur baby. I'm currently at the end of treatment with my Oreo. Got a bad corneal burn due to shampoo getting in his eye during a bath. Treatment can take up to two weeks or more. But, in most cases, the eye will heal. Just as others have said, have you tried removing the cone? He may not even bother the eye at all. Or, if he does, you can always opt for a soft cone. Here is the link to the person who makes them. Wishing your furbaby a speedy recovery.
