So far, I haven't heard of any life-threatening double eyelid cutting, that is to say, the "danger" in the conventional sense hardly exists. Blindness caused by eyeball cutting is a situation where the possibility is infinitely close to zero. Unless you are a "beautician" who practices your hands quickly with chicken legs in the studio, and your hands are shaking badly after a day's sleep, it is impossible to cause any harm to your eyes.

The real danger is anesthesia. Everyone has a different constitution, and some people are allergic to narcotic drugs. This kind of allergy is different from the anaphylactoid reaction caused by daily contact with allergens. Severe allergic reaction to anesthetics may even lead to myocardial infarction and cerebral hemorrhage. There are three clinical manifestations of severe allergic reactions: skin manifestations, cardiovascular reactions and respiratory reactions. As well as the "malignant high fever" that entered everyone's sight in the previous Limeikang incident, it is also an anesthetic allergic disease with particularity, heritability and extremely high mortality. It is also simple to avoid this "danger" in the conventional sense. It is possible to choose a hospital with formal medical plastic surgery qualifications. In regular hospitals, you can see the business license, the practice license of medical institutions, signing a contract with you before the operation, asking about your allergies, whether it is scar constitution, whether it is physiological period and so on.

There is also the danger of effect: the plastic surgery effect is not up to expectations. If the expectation is too high, don't say it. If it is not dangerous, just say the kind of failure: the double eyelids are asymmetrical, the eyes are laborious, and the double eyelids fall off. Some plastic surgery institutions take double eyelid surgery as a gimmick to attract customers, but the fact is that every operation has such risks. More serious things: eyes can't be closed, scars proliferate, real meat strips are obvious ... all possible.

And another fact: unfortunately, if it fails, even if the hospital is taken to court, it will not take much advantage. Because the definition of success or failure of medical cosmetic surgery is very vague, double eyelid asymmetry and real meat strips have not been classified as surgical failure.

The most reliable way is to carefully choose the right hospital, the right doctor and communicate with the doctor carefully before operation, but the success rate cannot be guaranteed to be 100%, because cosmetic surgery is inherently risky.
