I don't think that there is a good solution for this. That's why you'll hardly find indexes in non-fiction ebooks. And those who have them often often contain useless straight to ebook copies with non-clickable page numbers.
BTW, many hardware ebook readers also have a hardware Back button that'll take the reader back to previous location.
I.e. you might not have to provide an explicit linking mechanism back to the list of index entries.
Of course, you could add a link that would take the reader back to the original index entry. (I.e. you'd have two <a> anchors in a row: one index link target and one index list href.)
But each page number could only have one of those links and, IMHO, adding visible page numbers in the middle of the text would somehow disturb the reading flow and moreover page numbers might be mistaken for end-notes.
IMHO, hidden page numbers are a better solution if you decide to implement an index.
Maybe you could convince the author and/or publisher to omit the index in the ebook edition altogether because of these technical issues. After all, an index is primarily only useful for users of a print edition, since ebook users could easily search for any word using search function of their ebook readers.
