Corneal infection in the right eye. Dot.

About a month back, out of the blue, I felt irritation in my right eye, like some foreign particle was in my eye. Although I couldn't see any particle while self examining my eye. But I did notice how the white area around my eye ball had turned red and red veins showing up in the white area and while blinking, there was a feeling that something was in my eye. This went on for 5 days after which I noticed that a white dot had appeared inside my eye ball  (pic attached). I went to see the eye doctor. She said it was bacterial infection and gave me the following prescription: ocupol, milflox, lubrifresh. After10 days, when the white dot inside my eye ball didn't subside, she added Toba-F eye drops also. It has been 15 days now. Although there is no feeling while blinking, but the white dot is still there, somewhat faded though. And the red veins are still there. Since I am a working woman, there is no escaping the daily work on computer in office. I am concerned about the white dot.
