Good luck my man! When I had my right Retina tear and detachment I couldn't see for a month after the operation. I was so scared. My vision was whack before I had another operation to install a intraocular lens.Still a chance of limited to no vision, as long as things don't turn south.
They thought I would gain back a 100% vision but because the tear was so massive, I gained back about 85%. Better than blind of course.
