In practice, this sort of stuff will require very high levels of chemistry and biology, in which not only do the chemical formulas matter but also the 3d shapes of molecules and things like that (e.g. google protein folding). It's probably not impossible, but you're going to have a hell of a time with it, and something like programming is going to look trivial by comparison. Programming is trivial by comparison to normal doctors too, really, but nonetheless.
So it depends: are you willing to sacrifice years of your life for it? I wouldn't unless you really, really want to be in medicine. I'm not sure what the exact requirements on this are, but it's going to start with at least 6 years at a college and you probably need a PHD for starters--and I can't imagine that it's easier than normal med school, which has some ridiculously high failure rate for the sighted, never mind the blindness.
Put another way: if this question is "is this possible"? yeah, technically you can probably do it. If this question is "is this a viable career path"? The answer is something like only if you're okay with a high chance of failure and have some sort of burning drive that medicine is the one and only thing that you want to do, plus some sort of funding. Frankly that's how it goes for the sighted too, based off the couple of people I've known who have done this, but as a blind person you're always looking at 2x the work no matter what it is, and 2x "I study every waking moment" is certainly going to be intense. if you do decide to do it, I'd keep some sort of backup path in mind.
