Difficulty closing eyes after double eyelid surgery: what are my options?

I underwent Asian eyelid surgery last November. Surgeon removed a narrow strip of orbicularis oculi along the incision line & 2mm of skin. I can't fully blink or close my eyes and it has led to severe dry eyes. The gap is about 1mm in each eye. My lids feel tight and always in discomfort. I consulted an oculoplastic surgeon; he said the inner scarring seems tethered & if the gap is still there after 1 year, he might surgically remove the scars. What are my options going forward? Would 5-FU work?
