If your eyes are still swollen after more than a month of double eyelid surgery, it may be a normal reaction during the recovery period, and the duration of the swelling will be different for different surgical procedures. Double eyelid surgery is generally categorized into full eyelid surgery and minimally invasive double eyelid surgery. About one month after full eyelid surgery, it is normal for the eyes to be swollen, and the postoperative swelling usually lasts for about 1~3 months, and no special treatment is usually needed. In the case of minimally invasive double eyelid surgery, the swelling will subside in about 2-3 weeks after surgery. If the swelling does not subside, it is recommended that you follow up with your doctor in a timely manner. Double eyelid surgery can damage some of the tissues in the eye area, so it is important to follow the doctor’s instructions on how to take care of your eyes after the surgery, pay more attention to rest, and avoid touching the eye area with water, so as to avoid infections, scarring, and other conditions that affect your recovery.
