ophthalmic ointment for little boy!

Yesterday, my sister-in-low asked me about her son's disease.

She said, her son got red eyes with swollen for  3days.
Father brought him to Cambodian clinic, and got oral medicine and ointment.
I wondered about 'ointment'!

Her son is still 5 years old.

It is not easy to use eye ointment.
And price of medicine was so cheap, less than 1$.

I could not check that ointment but I was worry about ophthalmic ointment!
How could 5-years-little boy use ophthalmic ointment!
And why did he need to take oral medicine? I guessed this medicine was antibiotics.

Basically, this type symptom is treated with only eye drop!

I gave her an antibiotics eye drops and explain to her how to use it.

And today, his eyes can become better!
That's enough!

A doctor who has not enough confidence wants to use too much medicine, I think.
