I'm sorry that happened to your girl. Was this a friend of yours, a vet, or just someone who thinks he know's what he's doing?

I'd suggest taking her to a veterinarian to make sure she doesn't develop an infection. The general rule of thumb is to simply leave the eyes alone, eye caps will almost always come off by themselves in time with proper humidity.

That being said, posting a FaunaClassifieds BOI on this "Expert" is advisable after finding out what kind of permanent damage has been done at a vet's office. Someone that ignorant shouldn't be treating other folks' snakes.
