Eye plastic surgery belongs to aseptic incision surgery, and the operation time is not long. Therefore, according to the national regulations on the use of antibacterial drugs, postoperative antibiotic treatment is not needed. But in fact, due to the disinfection of instruments and operating environment, it is difficult to completely kill all bacteria, so antibiotics can be used appropriately to prevent infection. If the hospital doctor does not prescribe drugs and injections, he can ask the doctor to buy drugs orally to prevent infection. Using antibiotics without infection has no effect on wound healing and recovery.
