Hi. I'm online and happy to answer your question today.
For an existing, inactive corneal scar I am not sure what you mean by "steroid treatment"
Could you tell me a little bit more about the history of your corneal scar, how it has affected your vision, what caused it and how deep it is?
Also, what treatments have been recommended?
