If you don't finish cutting your double eyelids, there are some precautions after operation, otherwise it will be a waste of money. Generally, you only need to stay away from water for 5 days, and you can take some antibiotics orally. If you have the habit of wearing contact lenses, or your eyes are tired or conjunctivitis after using the computer for a long time, I suggest you use some anti-inflammatory eye drops together, which can help you get through a period of swelling and discomfort after operation.
