Did not follow treatment regime after PRK, stopped steroids too soon, can I start using them again?

I got my PRK in April 2018 for both eyes, and followed the treatment regime for one month only and then I stopped the steroids while I was supposed to keep using them for another month. I am regretting that now because my vision does not feel like 20/20. I cannot consult my doctor because I had my PRK done in another country. My question is whether to start the steroids drops again now (it is has been 4 months since the PRK and 3 months since I stopped the steroids drops) or is it too late?
