I made an account just to reply to you. I am 24 years old, always had eye sight problems and eye floaters. Got lasik, everything with my eyes are fine except very faint floaters in the very early morning.
I went on accutane once, around 20, with no problems(was on it for about a month). It worked so quickly, I convinced myself my skin was just getting better by itself and it had nothing to do with the drug, sadly that wasn't the case. I did it again years later, I noticed immediately that my floaters were getting stronger, and at almost all hours of the day. I also encountered nightmares, which sometimes involved waking myself up from the dream and encountering hallucinations for a few seconRAB.. I believe the accutane caused me to wake myself up unwanted and my mind got stuck in the REM state for a few moments.. theres some technical term for it (it didn't bother me much, I knew it was the drug, the only thing that annoyed me was waking up due to the nightmares, and the eye floaters. the hallucinations were cool, if anything. haha). I stopped. I went to the doctors for reason of floaters, they told me it was not really possible and they have no idea what I'm talking about. Do not listen to them, It is possible. Do you know how I know?
because my eye floaters went back to normal.. My doctors insisted accutane was safe, so i restarted taking it weeks ago. guess what.. my eye floaters are heavy again, and are at all hours.. I can see them as I type. However, no more nightmares, no more hallucinations. I am willing to put up with the eye floaters, as long as they do not get worst than this..
in your situation, I don't think its because of the accutane. it should happen instantly, I feel. I don't think it'll happen years later, if anything, it should heal.
MORAL OF THE STORY.. there is a reason why when you put in the word "Accutane F" it automatically puts floaters.. people search it, because people experience it. I am 100% sure my eye floaters are related to my accutane use.
