Eyes are too small, and you can only get bigger through plastic surgery. The common operation is to open the corner of the eye. Opening the corner of the eye is to correct the inner and outer canthus angles by surgery, remove the epicanthus, extend the horizontal length of eyelid cleft, and achieve the effect of expanding the eyes. Inner and outer canthoplasty was first used to correct microphthalmia and congenital microphthalmia. At present, with the development of cosmetic medicine and the increasing requirements of beauty lovers, inner and outer canthoplasty is also used to find normal people with big eyes. People who need canthotomy should be sure to be healthy before operation, do not wear makeup before operation, and women should try to avoid menstrual period. Eyes are very small, first of all, it depends on your age, and whether you have single eyelids or double eyelids, or your current age and so on. If it is congenital ptosis syndrome, we generally recommend to do two corrective operations before the age of three to treat strabismus and amblyopia at the same time. If it is congenital ptosis, it can be corrected by surgery at a suitable age. If it is severe ptosis, it will affect the development of vision, and it is necessary to operate in time.
