Necessity means that without surgery, the development of the child’s vision will not proceed normally, in other words, the child’s vision will be low, which may affect the development of vision and result in amblyopia and other symptoms, and feasibility means that the degree of ptosis has been fixed, and that the effect of surgery will not be changed after surgery because of the child’s growth and development. Congenital ptosis is usually fixed after the age of 1 year, but according to the development of the child around the age of 3 years, the formation of the inner part of the image of itself, at this time if the ptosis is not effectively treated, will affect the normal psychological development, so that 2-4 years of age when the operation is more appropriate.
