There are many types of ptosis, but most of them are congenital ptosis, and according to your baby’s age, if there is no history of trauma, it should be congenital ptosis. Depending on the severity of the ptosis, you will need to choose a different surgical procedure. If it is milder, you will choose to shorten the levator muscle, and if it is heavier, you will need to choose a frontalis flap suspension, with the former surgery costing about $2,000 and the latter costing about $2,500. After ptosis surgery the eyes are in the shape of double eyelids, so if the opposite eye is single eyelid, for the sake of symmetrical beauty of both eyes, the child is usually given a good eyelid surgery at the same time, but of course this can be done by the parents themselves after the doctor has explained clearly whether they agree to do it or not. The cost for a good eyelid surgery is 420 RMB. In addition, all children must be operated under general anesthesia, which costs more than local anesthesia, about 3,000 yuan. All told, the total cost for your child, including the above costs and the hospitalization for tests and medications, will be about $7,000-8,000. Ptosis usually requires surgery around the age of 3. Especially severe cases can significantly affect vision development and require surgery at an even younger age. If surgery is not performed after the age of 3, it may not only affect vision, but also negatively affect your child’s psychological development and ability to get along with peers.
