I Had Cataract Surgery (both Eyes) 6 Wks. Ago &

I had cataract surgery (both eyes) 6 wks. ago & now have double vision. I see objects sl. higher with my left eye. What treatment is there for this problem? It's very frustrating. A previous doctor had told me that I have Fuch's Dystrophy, but this doctor said I didn't actually have it or it was very slight. I would appreciate any help. Thank you.
