Hi, !
While my husband does not have MS, he did have cataracts surgery on both eyes. While his vision improved a great deal, he still needs to wear reading glasses. If you are experiencing double vision for much longer, I would definitely talk to your eye doctor about it, if you haven't done so already. It can take awhile for the double vision to ease and I hope your brain adjusts to the changes so you don't experience the double vision so much.
In theory, you *should* experience much clearer vision, but every person recovers from surgery uniquely and MS does add another element to your recovery process.
