Trauma, inflammation, tumors and congenital malformations can cause atrophy of the eyeball, which not only results in loss of visual function, but also causes facial defects, which seriously affects the patient’s mental outlook and quality of life. As far as the current medical level is concerned, it is not yet possible to transplant a functional eyeball to restore vision to patients with atrophied eyeballs or patients without eyeballs after eyeball removal, and the experimental research on electronic eyes has just started, so we can only improve the appearance of such patients through the implantation of simulated prosthetic eyes. With the advancement of prosthetic eye materials and technology, especially individualized prosthetic eye production, it is almost possible to achieve the effect of imitating the real one after wearing the prosthetic eye, which greatly improves the patient’s appearance. If the eyeball is removed during childhood, the installation of the prosthetic eye is particularly important because the orbital and facial bones of children are not yet fully developed. Without the stimulation of the eyeball and orbital contents, the development of the bones and soft tissues on the affected side will be stagnant or delayed, leading to asymmetric facial development, which will result in facial deformities that are difficult to correct in the later stages of life. Research shows that the timely installation of prosthetic eyes after the removal of the eyeballs in children can replace the stimulating effect of the eyeballs on the development of the eyes, so that the development of the face and face tends to be symmetrical, laying a good foundation for the later surgical plastic surgery.
