Personally I wouldn't worry about it, given it was an honest mistake, so long as more recent papers that refute your claim cite your paper. Whenever I'm reading an interesting paper I always do a reverse citation search to see what more recent papers say about it. I find that if a paper's claims are important enough someone in the field will publish a paper if they have results that contradict it.
