Bariatric surgery = vision problems?

Just curious, I'm a year out from VSG and I started having double vision a few months ago, which has in the last week gotten more severe. Since I'm only 33 and have no other symptoms, my PCP is thinking it's possibly a vitamin deficiency related to my surgery.  My last blood work was in January and all was fine.  I'm going through a series of tests as well as an MRI to rule other things out, but I have never heard of any symptoms of this type in other patients.  Any one else experience this or something similar?

 Not here.  Of course I have bilateral cataracts as a complication from my diabetes being ncontrolled before the sleeve.  

I found this on google?  Maybe this is what your doctor is talking about?

I haven't had double vision, but I do think that my glasses prescription has changed.  I have noticed I am having a harder time seeing far away and the glasses I got right after surgery do not work.

When I have previously inquired about having LASIK eye surgery, the Dr. told me that I needed to wait.  If you lose weight, and blood sugar levels? change, your eyes will also change.  I just told my Mom on the phone 2 minutes ago that I can't wait to get to goal, so I can finally get my eyes fixed!  (I'm legally blind in both eyes...)
