No the glasses RX will not cause problems. The difference is without glasses your distance vision is much better than it's been for many years and your near vision is not clear. Your glasses RX should have an "add" e.g. +3.00 add and your glasses no line multifocal progressive lens. Any problems will likely be related to your high myopia. That is due to a long eye and that didn't go away. Just your glasses RX different because the rest of the thick RX is in your eye on the IOL
By 5 months vision is fully stable, usually they'll even consider laser correction by 3 months since its stable.
To be more specific than the doctor's post, any risk of retinal issues are related to high myopes having longer than average internal structures so their risk of things like retinal detachment and other issues is higher. The surgery didn't change the size of your eyes so those risks are still present, and the hyperopia doesn't change that risk (in either direction) since the refractive error itself isn't what causes the risk.
Actually your LE isn't quite as farsighted as the +0.75D indicates due to the mixed astigmatism. Your eye's power in one direction is +0.75, while in another it is (+-.75 + -1.00) = -0.25D, for an average power, called the spherical equivalent, of (+0.75 + -0.25) / 2 = +0.25D. Unfortunately astigmatism does cause blur reducing the quality of vision a bit so overall your vision is likely not as good as it could be even for distance in that eye.
Some people consider getting a minor LASIK/PRK tweak to their vision if they wind up hyperopic with an IOL because it reduces their near/intermediate vision, which is already very reduced with a monofocal IOL, which can correct the residual astigmatism as well. Some highly myopic people who weren't candidates for a large laser correction (e.g. due to corneal thickness) may be able to get the smaller correction required for something like that. If your RE has good enough distance vision (which it may despite a bit of astigmatism, it could be even better than 20/20) you could even consider adjusting the LE to be a little bit nearer in monovision to give you a larger range of vision (though not everyone likes monovision, you could do a contact lens trial). Small corrections tend to be more accurate than large ones.
I have one eye left +0.5D after cataract surgery that I may eventually get a laser tweak for, but in my case its less of an issue since that eye has 0D astigmatism so distance is decent, I have the Symfony IOL for a larger range of vision, and my other eye was on target to balance it out to give good vision over a large range.
