| Lacrimal tract irrigation, conjunctival sac irrigation, palpebral margin/eye skin/facial skin disinfection | ① Take the body temperature, replace the breathing mask by a new one provided by the hospital at the entrance of the operating room, take off the shoes, wear shoe covers, and give a surgical gown to the patient.
② Ventilation during operation.
③ The patients should be at least 1.5 meters apart when waiting.
④ Lacrimal tract flushes one person, one needle, and one tube; the conjunctival sac flushes the eyewash pot, and the treatment towel is changed one by one. | ① Immediately after flushing the lacrimal duct and conjunctival sac, use 75% alcohol spray to disinfect the air in the operating space.
② A laminar flow operating room is preferred. If there is no laminar flow system, the air sterilizer can be used to set the cycle work and combined with mechanical ventilation (such as electric fans, medical staff is on the upper air outlet).
③ Shorten the use time of the filter nozzle of the particle absorption system of the laser equipment and disinfect the laser exit with ultraviolet rays after the operation. | ① Medical N95 mask, hat, goggles, gloves, disposable surgical gown. Fully closed goggles should be worn in the operating room.
② Wear a face shield during lacrimal tract irrigation and conjunctival sac irrigation.
③ Face shield and goggles should be disinfected before and after use. | Wear a hat before disinfection. Disinfect palpebral margin first, then eye skin and facial skin. (When disinfecting the facial skin, the breathing mask is pulled down between the mouth and nose.) |
| During surgery | ① Change sterilization gloves, a set of instruments, a tablecloth, and a handle cover for each person.
② Aseptic operation.
③ One in and one out. After one surgical patient goes out, the next patient enters again.
④ Strictly control the total number of operating rooms.
⑤ After the slit lamp microscopic examination, the forehead and mandibular support were eliminated by one person. | ① Remove the breathing mask and put it in a special bag. After disinfecting the face for the second time, immediately lay on the operating table and put on a sterile hole towel.
② After the operation, wear the breathing mask immediately after getting up from the operating table. |
