Your post was rather long, but necessarily so.  You did a good job
explaining the parameters of your problem.
   The situation you are describing is certainly not a "botched"
surgery.  I have seen "botched" surgeries where the implant was dropped
into the posterior chamber and left there, I have seen iris tears from
poorly placed implants.  The parameters you are describing are well
within the normal limits of cataract surgery, especially with retinal
complications.
Before implants were invented, everyone who had their human lens
removed had nothing at all put in the eye to replace it.  Then everyone
wore "cataract glasses" of about +20.00 Diopters!  Then, the
post-cataract extended wear soft lens became the regimen of choice to
attempt to return image sizes to normal.

When an IOL is taken out and replaced to change its power, the standard
of care is to never put the new implant in the same location behind the
iris. These secondary implants are anterior chamber implants, and they
will certainly add to your image disparity.

There are possible solutions that involve moving your correction out of
your glasses and onto the plane of the cornea, and these options
include contact lenses or refractive surgery.  You don't need another
surgery, you need the issues mentioned in the other posts above to be
addressed by a good refraction and a purely optical solution with no
cutting involved.
