1.Operation purpose: to install a prosthetic table, increase the fullness of the eye socket, lay the foundation for wearing a cosmetic eye piece (prosthetic eye), and try to improve the appearance. 2.Surgical materials: Currently, the following are commonly used in China: bioceramics (bone china), porous polyethylene (Medpor) and hydroxyapatite (HA), etc. 3, the main surgical risks 1) the prosthetic table material does not adapt to the prosthetic table exposure (the probability is about 1-3%), there is infection or granuloma when the prosthetic table removed. 2) Orbital fat resorption and eyelid depression (10-20% probability), re-surgical implantation of artificial bone for orbital volume reduction if necessary. 3) Poor or no rotation of the prosthetic table, mainly in patients who have had secondary surgery or who have had atrophy of the eyeball since childhood resulting in hypoplasia of the extraocular muscles. 4) Ptosis, which occurs mainly in prosthetic table implantation without the eyeball, is reviewed after 3 months postoperatively and surgically corrected if necessary. 5) Conjunctival sac stenosis, inability to wear or customize the cosmetic eye piece, re-surgical correction after 6 months if necessary. 4. Precautions: A. Pre-operative 1) Point antimicrobial eye solution in the operated eye. For patients who have removed the eye and wear prosthetic eye piece, if the conjunctival congestion is serious, do not wear the eye piece for the time being and point medication to control the inflammation before surgery. 2) Psychological expectations should be appropriate. Each person’s own conditions before surgery are different, and for cases such as secondary surgery, history of trauma, orbital dysplasia since childhood, and malformations of the eyelids and conjunctiva, some patients may need multiple surgeries, which are usually laborious, time-consuming, laborious, and have limited results. B. Postoperative 1) Try to look ahead in the normal eye and reduce eye rotation for 1 week after surgery. The first 2 days the dressing is wrapped and not opened. After opening the dressing, spot eye solution 1-2 times a day (such as iodine Bisch). If there is more secretion, wipe with a cotton swab on the surface of the eye mold. 2) 2 weeks after surgery is the time for the first outpatient review. 3)A transparent temporary eye mold with 2 holes is worn for 6 months after surgery to facilitate the ordering of eye drops and wiping of secretions. 4)It is recommended to wear the cosmetic eye piece 6 months after surgery because it takes 6 months to 1 year for the prosthetic eye table and its own tissue to grow together completely (vascularization).
