Generally speaking there are no websites, certainly in the US, that will make custom formulas for the public (i.e. not a licensed practitioner). In China, that would be another story. Most practitioners are probably turning you down because it is largely unethical to make a formula for someone where you don’t know their entire medical history, can’t track their progress well, and, most importantly, are doing it without the ability to physically inspect them (tongue, pulse, diagnosis, etc.). Studies, while valuable, rarely offer cookie cutter approaches as outcomes, so some will correctly feel that making a formula for you, without seeing you personally, based only on a fairly small study, would be wildly unethical (and I would agree with them).
Again, most practitioners should be able to help with this. Our page, acupuncture for optic nerve atrophy, has some general pointers for working with this range of issues. This is, of course, somewhat different when it is result of ethambutol reactions. These are somewhat rare, seem to self resolve within a few months in most people, but can be complicated particularly if the western physicians didn’t monitor vision during treatment and/or a dose that was too high was given. Either way I think if you can find someone to treat you for 3-4 months (only 1-2x week would be required, more than that would likely be far less effective, possibly even counterproductive) who is reasonable skilled you should be fine. Keep in mind that you want to see a fully trained Chinese Medicine practitioner, not a general medical person (MD, PT, Physiotherapist, etc.) that also practices “acupuncture”.
