I had a non-incision double eyelid surgery a month ago. It is suppose to heal within a month. However, one of my eyes is still very swollen after a month while the other had healed completely. Now my eyes look very weird and uneven. My dr said the swelling would subside within a month during the first review. Now one month is over, he said it should subside after another 3 weeks. Is it normal for my eye to take such a long time to heal or the stitching is not done properly for this eye?
