I am suffering from corneal ulcer after PRK surgery. What is the treatment?

Hello doctor,

I have done PRK eye surgery about a month ago in both eyes. A few days later, my left eye had some weird blurred vision which turned out to be corneal ulcer that is in the center and relatively big. I got treated immediately with heavy antibiotics Ceftin or Vigamox. After two to three weeks there was some improvement in vision, redness and the loss of epithelial cells is about 1.2 mm, after which I started taking eye steroids, and vitamin C three times a day. Unfortunately, I found out today that there is another small epithelial defect that opened under the first one (both are still very small). I have bad light sensitivity, and I would like to know if there is anything to be done now apart from waiting to get better. I have been told to be patient at least three months since the scarring is still prominent and central, although it is getting slightly better every time I see the doctor. I am currently on, antibiotic eight times a day with steroids three times and Sythnomyine twice a day. Most of the scar is in the front stroma. But central, and it has been slightly getting brighter every time.
