Does it take 2 to 3 weeks for a bacterial eye infection to heal?

Hi doctor,

From the last two weeks, my eyes are reddish. So after three days, I consulted an ophthalmologist, and he said that I have got an eye infection, and he suggested to use Vigamox, Floace, and tear eye drops, four times daily. But after two days, my vision started to blur, so I rushed to the doctor again. He again said it is a bacterial infection, and he said it will take two to three weeks to recover. I am using the prescribed eye drops from a week, but my vision has not recovered even a bit. I am afraid because, before the infection, my vision was 100 %, but now my left eye is totally blurred. Will it take three weeks to recover? Do I have a corneal infection? Please help.
