I had a cold sore develop on my right cornea about 5 years ago. it was treated with drops and seeing an eye specialist often. It seems to have calmed down and I now use fml drop 2xper day and take valtrex once a day and another antibiotic. these meds im told are long term.. my question is I have been left with a great amount of scar tissue around the eye and its never faded, is there a way of removing the scaring. it looks just awful and I am very bothered with that.
