A lot of people are successful - and don't know it. From my own research, it is very clear that two NORMAL eyes can have a refractive difference of 3/4 to 1 diopter. Believe it or not - that is normal. Further, you test with both eyes open, on a bright Snellen, and you have 20/20. That is real success, that all the rest of us can only dream about.
It my private judgment, if you are willing to continue, then both eyes will change by about +1/2 diotper, in about six months. That means that one eye will have a "positive status" (totally normal), and the other eye will "get to" 20/20. But this is totally personal. The only person who can ever do this and judge this - is yourself.
Thanks for your successful report - we need more people like you.
With time I believe more and more that this diplopia after rehabilitation is more of a brain's matter as Dr Alex and Jake say. They also say that with good vision habits and plus lenses the eye changes in a good way so fast that the brain can't catch uo.
With my last measurements I can even see 20/20 only with one eye, the one that diplopia has gone away. The right one that I'm complaining about is about 20/40 and the bad thing is that it doesn't have one sharp image and a second more faint but the two images are about the same sharpness-darkeness or can even alternate the stronger image becoming weaker and vice versa.
So the most likely scenario is that my brain worked well for resolving diplopia in my left eye, gave his whole work on my left eye and left behind the other eye unregulated from diplopia.
So the eyes can heal quickly (about a diopter per year) from myopia but at the last dioptre the diplopia needs more time to be resolved by the brain (in order to catch up).
I also believe that if I hadn't diplopia at my right eye then this eye would be 20/20 now even if now is 20/40.
