7 weeks after strabismus surgery - still double vision

I am on week 7 after my strabismus surgery and I still have a double vision. For the first 2 weeks it was terrible, total double vision, after the third week it started declining. I regained normal vision when looking down, I could finally see 2 legs instead of 3 or 4. Then I could see 2 hands the next day instead of 3. In later weeks it improved a lit, I have normal vision when looking far away, normal vision when using my phone and looking at near objects, but at the middle distance I see double. I am also afraid that it won’t dissapear. My strabismus wasn’t severe. I had alternating strabismus, my eyes could be aligned when looking at near objects, I never had double vision before surgery, and I don’t have a binocular vision. If I looked at you with my left eye, my right eye would drift away and vice versa. I had the surgery at December 2 in Belgrade, Serbia. It was a classical surgery on both of my eyes. On my right eye only one muscle - exterior, and on my left eye 2 muscles - exterior and interior one. My left eye took much more time to recover then right eye as it had only one cut. My eyes healed greatly, this is my first surgery at 31 years and my eyes weren’t bloody or red, more of a pink colour. I barely could open them the first week (I kept left eye closed). Is there somebody here who experiences double vision for so long? My check up is in March, as they say eyes take 3 months to heal and to know if the surgery was success or not. On my first week check up doctor said that some adults take a few months to lose double vision.
