All operations have certain risks, but if beauty lovers choose highly skilled doctors in regular hospitals for surgery, the risk of surgery will be greatly reduced. Opening the corner of the eye is a delicate operation, which will take a long time, about 1-2 hours. It takes 5 days to remove stitches in canthus surgery, and traces will be left after eyelid surgery. It usually takes 3 months to half a year, and the longest recovery time of canthus surgery takes one year to fully recover, so it is best to rest for 2 days after surgery. Therefore, the operation of opening the corner of the eye must be cautious. You should go to a regular medical beauty institution and choose an experienced doctor to do it. Not all inner canthus can be opened, and not all inner canthus can be elongated when the eye fissure is opened. After years of continuous research, canthotomy combined with double eyelid liposuction has the characteristics of small incision, little injury, quick recovery and no trace, which is safe and effective. When performing canthotomy, the lacrimal caruncle should be exposed as completely as possible. Open canthus surgery can increase the length of eyes by correcting epicanthus, and sometimes double eyelid surgery can be done as needed, so it is very important to choose a professional plastic surgery hospital.
