Liposuction

Why would my skin doctor give me an ophthalmic ointment which is commonly used on dogs for my zits?

Here’s the thing…
Whenever i have a huge breakout (due to a hormonal imbalance), i would go to this dermatologist in an aesthetic clinic (where they provide services like chemical peeling, botox, liposuction, collagen boost, etc) to laser on my huge zit. So every time after the doctor "laser" on my zit, his assistant would apply on a cream/ointment and also give some of it to me as a two day supply to be applied on the lasered zits, supposedly somekind of antibiotic/antiseptic cream i guess? So this time they gave it to me in its original packaging.
It’s called "Terramycin": Ophthalmic Ointment. (by Pfizer)
I felt weird that i have to use an ophthalmic ointment for my skin, so just now i googled on "terramycin ophthalmic ointment". I was so surprised to see that all the search results conveys that this ophthalmic ointment is normally used on dogs. Even all the websites that shows up are all vet and pet websites.
I don’t think this make sense at all. Can someone perhaps with a medical background or experience in this matter enlighten me with a convincing answer please?
