I have decompensated strabismus eye wanders out. had 3 surgeries. now in 10 dpi base out.. can brain reject high strength?

What is your goal: A wandering eye does not need treatment if you do not get double vision. Have you tried glasses without prism?

Eye wandering: Strabismus surgery will often not hold the eyes in alignment if one eye has very poor vision, or if the eyes have no capacity to work together (binocular vision). If you never experience double vision when the eye is turned out, strabismus surgery might not work.
