Prosthetic eyes, like artificial limbs, artificial joints, etc., is to the less perfect, sound human body a necessary complement, but it is different from the general “human body parts”, because the eyes are the windows of the soul, who do not want to be bright-eyed, beautiful eyes, so the practical function of the prosthetic eye is far less than its aesthetic role. It can be said that each of the people who installed the prosthetic eye may have had a bitter encounter, but still have a beautiful vision, to see such a few of the “beauty” of the diligent pursuit of the girl, they have their own twists and turns of the story. “Nowadays, people are becoming more open about the need for eye prostheses, but there are still a lot of tips to learn as you go along.” There are several misconceptions that people who are fitted with prosthetic eyes tend to fall into. Misunderstanding one: the installation of prosthetic eyes but not the prosthetic eye seat Beautiful girl wearing a prosthetic eye wear into the face of the depression Long-haired Ah Xiu this year, 23 years old, looks very clean, but a closer look can be found, her eyes around the appearance of a slight depression, and the left side of the skin of the face is obviously full, flat a lot. It turned out that due to the hour of illness, Ah Xiu right eye blindness, poor economic conditions at the time, it was in the local hospital to wear a prosthetic eye, followed by more than a decade without seeing a doctor. She felt her face around the eyes collapsed, but did not know is a prosthetic eye problem. Earlier this year, her boyfriend told her that she now had a “movable eye” to match, so she came to the hospital. Face depression is caused by years of wearing a prosthetic eye without a prosthetic eye seat. Huang Danping gently pressed the loose skin around the eyes of Ah Xiu said, in the 1980s and 1990s, technology is not developed, people tend to think that the installation of prosthetic eyes is a similar size of the prosthetic eye can be installed, no one knows to first install the prosthetic eye seat inside. There are three main reasons for this “upper eyelid depression” after eye removal: firstly, the four rectus muscles recede towards the orbital apex after eye removal, and the upper rectus muscle pulls the levator ani muscle backward as it recedes. Second, the orbital contents decrease by 6.5-7 ml after eye removal, of which the volume of the eyeball accounts for 6.5 ml, whereas the volume of the prosthetic eye is only 2 ml, which is insufficient to compensate for the volume of intraorbital tissues lost by the eyeball removal. Finally, surgery or trauma can also cause atrophy of the intraorbital fat. A measure to prevent upper lid depression after eye removal is to place a prosthetic seat at the same time as the eyeball is removed. The key to whether the prosthetic eye is good or not is in the prosthetic seat “People tend to care a lot about how the prosthetic eye looks, the color …… because it’s directly what everyone can see, but for the prosthetic seat people don’t care, in fact, the prosthetic seat is the real house, and the prosthetic eye is just the external decoration. Whether the prosthetic eye is good or not also depends on the prosthetic eye seat. First of all, people should understand the complications of prosthetic eye seat implantation, there are five kinds: prosthetic eye seat exposure, prosthetic eye seat position abnormality, prosthetic eye seat infection, bulbar conjunctival thinning and conjunctival damage. Secondly, one should know the indications for prosthetic eye seat implantation, which are as follows: 1. Non-infectious eye disorders that require eye removal, such as glaucoma with pain, huge rupture injury of the eyeball, and angular scleral staphyloma. 2.Infectious intraocular disorders, such as endophthalmitis. 3, Eye atrophy can not tolerate or should not wear prosthetic eyes. 4.Primary malignant tumors confined to the eye, such as retinoblastoma and choroidal melanoma. “Prosthetic eye seat implantation also has contraindications, such as ocular infectious disorders – total ophthalmoplegia.” There are two main types of prosthetic eye seat material There are two main types of prosthetic eye seat material currently in use: one is called “hydroxyapatite prosthetic eye seat”, also known as coral hydroxyapatite prosthetic eye seat. Since hydroxyapatite is the main inorganic component of human bone tissue, it has good histocompatibility, non-toxicity and non-antigenicity. Since this material retains a microporous tract structure, it can be used as a mesh scaffold to allow fibrovascular tissue to grow in. Full vascularization can be achieved 4 weeks after implantation into the body. Furthermore, this material does not cause significant foreign body inflammation when implanted into tissue, and when used as a bone substitute, it resists moderate stress and has no significant resorption for 48 months. Clinical and experimental studies have shown that coral hydroxyapatite prosthetic seats have good biocompatibility, body affinity and bioactivity. “The other type is high-density polyethylene.” High-density polyethylene is synthesized from linear high-density porous polyethylene biomaterials with inter-traffic pores, fibrous tissue and blood vessels can grow into the holes after implantation of the tissue, the material has good histocompatibility and stability, non-allergenic, non-rejection, non-absorbable, its strength changes with the temperature, it can be shaped as many times as needed, and there is no need to worry about the collapse of the hole structure. Prosthetic eye can also be personalized Prosthetic eye in the trial wearing process, would rather do a little bigger, it is best not to do small, because big can be polished at any time to become smaller, and small to make up for the big may be both inconvenient and unattractive. In addition, the prosthetic eye has some slight blood color, because the adult sclera (the white part of the eye) will have a little blood, so the prosthetic eye will look more real and natural if you do so. In addition, how white the eye is, whether the pupil is darker or more brown, the size of the pupil, etc. are all carefully referenced to the patient’s other healthy eye as well as the patient’s age and skin color. For children’s eyes, blue color is usually added to make it look more crystal clear. Myth 2: The prosthetic eye is installed once and for all The life span of the prosthetic eye is only 5~10 years “Doctor, why does my ‘eyeball’ seem to get dirtier the more I wear it? Why can’t I wash it off?” Ah Xiu has another agonizing problem. Compared to Ah Xiu’s agile and free left eye, her right eyeball is very cloudy in color and her eyeball cannot move. She is a very clean girl with white skin and is at a good age, but her “prosthetic eye” is cloudy and yellowish, which makes her very embarrassed, while in contrast, her left eye looks black and white. She also felt as if something was stabbing her inside the prosthetic eye, and it was no longer worn as properly as it had been when she was a child. “This is because you have not changed the ‘prosthetic eye’ for more than ten years,” prosthetic eye like drugs, electrical appliances, all have a service life, if beyond the effective life is not replaced, naturally, both the appearance of the color and the inner will gradually age, decline, and thus the appearance of Color fading, wear uncomfortable and other problems. Generally speaking, the life span of a prosthetic eye is 5 to 10 years, and children may change more, because the orbital bone will slowly become bigger with age, and there is a certain difference in weight gain or loss. If you feel uncomfortable wearing a prosthetic eye, you should consult an ophthalmologist and an ophthalmologist as soon as possible to find out the cause and make appropriate adjustments. Myth 3: the real eye is always better than the fake eye long tumors in the eye must remove the eye 20-year-old Xiaolian childhood eye trauma led to blindness in the left eye, although the eye can not see things but she always felt that the real eye is better than the fake eye, the thought of digging it out, it is not willing to die. Therefore, Xiaolian always wears long bangs, thus blocking her left eye. In fact, for patients who have to undergo eye removal due to malignant intraocular tumors, severe endophthalmitis, severe ruptured eye injuries, absolute stage glaucoma with pain, and corneoscleral staphyloma. Tumors like intraocular tumors are the number one reason for eye removal, followed by ocular trauma. While eyeball removal may be very traumatic for the patient, the tumor may spread without it. Prosthetic eyes must be placed after eyeball removal because of the reduced loss of orbital contents and concave sockets, and if an implant is not placed in the orbit to fill the postoperative void, secondary deformities such as loose or ectropion of the lower eyelid and shallow narrowing of the inferior colliculus can occur and interfere with the prosthetic eye fitting. If the eyeball is removed in childhood, due to the lack of orbital bone eyeball rotation on the growth of the stimulus, over time will cause orbital and peripheral muscle dysplasia, orbital volume shrinkage, asymmetric facial development and other deformities, not only affecting the appearance of the aesthetic appearance, but also on the children’s mental health will have a negative impact.” Huang Danping said, wearing a prosthetic eye has other roles, such as preventing the orbital retained soft tissue fall; prevent eyelids and eyelashes to grow inward; to help tears continue to do clean circulation and the orbital and eyelids to play a lubricating role. Every six months to the hospital to wash the “eye” If the quality of the prosthetic eye is low may directly affect the hygiene of the eye socket, common problems such as may cause inflammation of the eye socket, the discharge of dark yellow secretion, feel uncomfortable. However, a good quality prosthetic eye is made of anti-allergic material, and the wearer does not need to take it out and clean it every day, as the tears will help it to do the natural cycle of cleaning. However, the following should be taken care of on a daily basis: 1. Under normal circumstances, the prosthetic eye should be worn as if it were your own natural eye, whether you are working during the day or sleeping at night. It will not interfere with participation in various activities, such as ball games, fitness, swimming (swimming goggles must be worn), and so on. Therefore be sure to take it out and clean it every day. 2.After installing the prosthetic eye, pay attention to keep the prosthetic eye and conjunctival sac clean and hygienic. Regularly take out the prosthetic eye in one to three months (with the help of instruments, avoiding direct contact with hands), and put it back on after rinsing with saline, which can reduce the bacteria into the eye. 3, every six months to a year back to the hospital for examination, and let the doctor to do professional cleaning of the prosthetic eye, so as not to destroy the surface of the surface of the prosthetic eye in the personal cleaning process, because the prosthetic eye in wear for a period of time, there will be a layer of human body proteins accumulated on the surface, is the need for professional processing, to re-create the most surface layer of the liquid crystal body. 4, the weather is dry, windy or in the cold open environment of the eye will have a bitter uncomfortable feeling, drop some lubricating eye drops (nutrient water) can help. 5, eye removal together with prosthetic seat implantation 3~4 weeks after the surgery, conjunctival wound healing, no edema, you can install the prosthetic eye. If old and weak or uncooperative children, it should be extended to 4~6 weeks after the operation. However, the extension should not be too long, otherwise it will cause the conjunctival sac to shrink and become narrower, which will cause difficulties in installing the eye prosthesis in the future. 6, to regularly replace the prosthetic eye, especially children patients with age, orbital development, should be replaced at the right time with a new prosthetic eye suitable for the size of the conjunctival sac. If the orbital implant mobility is good, most of the patients can achieve light or medium mobility effect of the prosthetic eye, and the appearance is more satisfactory. 7.After 2~3 years of prosthetic eye installation, due to gravity, the prosthetic eye may move down and the upper eyelid ptosis, at this time, you can replace a prosthetic eye or perform eyelid ptosis correction surgery. 8, and the other eye can still read as usual, but it is best to do a safer work, because there is only one eye left, so we must be especially careful to maintain, in addition to regular eye examination, but also to prevent accidental injury.
