Double eyelid cutting, also known as incision double eyelid, is now a very routine and mature method, with a high success rate and high patient satisfaction, and few complications if you find a legitimate doctor at a regular institution. However, many patients are afraid to mention the incision, I think it is mainly because there are friends around who did not have good double eyelid results, or read the wrong propaganda on the Internet, mistakenly believe that the double eyelid incision will be very painful and swollen, in fact, through my clinical practice, many patients’ feedback to me is that the double eyelid incision is only slightly painful when injecting anesthesia, and the post-operative swelling is acceptable, much better than the patient imagined before surgery. It is much better than the patient thought before surgery. In the last decade, the number of people who are suitable for open double eyelids has been increasing. The main reason for this is that some young people often use double eyelid patches or stay up late at night, resulting in loose upper eyelids that are no longer suitable for buried or positioned double eyelids. If minimally invasive double eyelids are done in the case of loose upper eyelid skin, sagging upper eyelids and swollen eyeballs, then they may become single eyelids again in a short time. Therefore, the premise of minimally invasive is to have the effect, and it is meaningless to talk about minimally invasive if it is detached from the effect.
