Hello, infection is one of the symptoms after eye bag removal, mainly manifested as redness, nonunion and even pus or exudate around the incision. Director Dong said that this situation can be prevented. The causes of infection after blepharoplasty are: (1) conjunctivitis, blepharitis and other eye diseases are not controlled before blepharoplasty. (2) No attention was paid to aseptic operation in blepharoplasty. Infection caused by unclean incision or stagnant water after operation. Thread ends are left when stitches are removed, leading to infection. The prevention and treatment of this situation are as follows: in addition to strict aseptic operation, eye drops are routinely used 1-2 days before the operation to relieve keratitis and conjunctivitis. Those with severe conjunctivitis, keratitis and blepharitis are not suitable for blepharoplasty. Patients should be instructed to reduce sweating and keep the incision dry after eye bags are removed. When the infection has formed, it can be treated locally by physical therapy, partial suture removal, drainage, dressing change and oral or injection of antibiotics.
