Opening the corner of the eye is a delicate eye plastic surgery, which takes about 1-2 hours. The swelling reached its peak on the second day after operation, and then gradually subsided, and the swelling could be reduced in about a week. Under normal circumstances, you can basically recover in about a month, but if you want to make the scar disappear and your eyes become more natural, you have to wait about three months. Secondly, the recovery time after canthotomy is closely related to personal physique, doctor's skill and postoperative nursing. If you want to recover quickly and naturally after operation, postoperative care should not be sloppy. Postoperative care: do not take aspirin after operation. Don't get wet for a week after operation. Do a good job of cleaning to prevent wound infection. You need a quiet environment to cultivate after canthus surgery.
