Do you think I may have an infection or a irritation of my left eye? Will my vision return to normal in my left eye? (Photos)

I had a face lift and lower/upper eye lid surgery 3 months ago. Everything is healing great except for my left eye. I have been experiencing double vision and blurriness for about a month and it appears to not be getting better. I have visited an ophthalmologist who thinks it's dry eye and has given me some eye drops for the dry eye, but the double vision /blurriness remains. For the past couple of days, my lower lid at my left eye has been swollen, irritated & itchy.
