Trauma, inflammation, tumor and congenital malformation can all cause eyeball atrophy, which not only causes visual function defect, but also causes facial defect, which seriously affects patients' mental outlook and quality of life. As far as the current medical level is concerned, for patients with atrophy of eyeball or anophthalmos after enucleation, functional eyeball can not be transplanted to restore vision, and the experimental study of electronic eye has just started. For this kind of patients, we can only improve their appearance by implanting artificial eyes. With the development of materials and technologies for artificial eyes, especially personalized artificial eyes, the effect of wearing artificial eyes can almost be achieved, which greatly improves the appearance of patients.

If the patient underwent enucleation in childhood, it is particularly important to install artificial eyes, because the children's orbit and facial bones are not fully developed. Without the stimulation of eyeballs and orbital contents, the development of bones and soft tissues in the affected side will be stagnant or delayed, leading to asymmetric facial development and facial deformity that is difficult to correct in the later stage. Studies have shown that installing artificial eyes in time after removing eyeballs in children can replace the stimulating effect of eyeballs on eye development, make facial development tend to be symmetrical, and lay a good foundation for later surgical plastic surgery.
