eyesight change after surgery??

Normally when I hear vision changes after RNY I think vitamin A deficiency but I really think you are too soon out for your vitamin A too have gone down that much. I became vitamin A deficient but it was at 3 months, not 3 weeks. I would suggest the next time you are at one of your doctors, you ask to have your vitamin A level checked just to be sure. In the meantime, make sure you are taking your multivitamin 2 times per day and get in all your fluids.  If you have dry eye or allergies, keep your eyes hydrated.
