A, cleaning and maintenance 1, cleaning methods: should be taken off daily to clean, first wash with flowing water to clean the surface adhesion, then rinse with saline or pure water, dry with a clean soft cloth and carefully stored. Generally wear during the day, take off at night to wash and store, wear before the antibiotic eye water containing sodium glassate lubrication eye piece will increase the comfort of wearing. Long-term non-use of the prosthetic eye piece should be placed in a closed container dry storage, in principle, should not be placed in water. 2, regular disinfection: eye prostheses should be cleaned weekly with soap solution surface adhesion, and use iodophor soaking disinfection. 3, pay attention to protect the surface of the prosthetic eye: cleaning, disinfection and other treatment of the prosthetic eye, should use soft cloth, so as not to wear the surface of the prosthetic eye lint affect its gloss and wearing comfort. Do not use disinfectant solutions that have corrosive effects on the prosthetic eye, such as alcohol. When cleaning the prosthetic eye, you can use a soft cloth dipped in some toothpaste to rub and polish it, or you can go to the hospital’s prosthetic eye studio and ask a professional physician to polish it. 4, regular replacement: due to the erosion of tears and long-term friction, the surface of the prosthetic eye will gradually become rough, its color and gloss will also decline, and with the growth of age, the color of the healthy side of the eye will gradually darken, and there is a significant difference with the prosthetic eye, thus affecting the beauty, in this case should be replaced prosthetic eye. If the prosthetic eye piece is obviously worn out due to accidental reasons, you should not wear it reluctantly to avoid damaging the conjunctival sac and should replace it as soon as possible. Second, after the installation of prosthetic eye complications and their treatment 1, conjunctivitis: for the human body prosthetic eye is a foreign body, the body will have a certain rejection of it, at the same time, due to the movement of the eyelid and the rotation of the eye in the process of the friction of the prosthetic eye, these factors will stimulate the conjunctiva induced inflammation, patients will appear eye red, eye grinding, increased secretions and other discomfort, this situation occurs in the wearing prosthetic eye This happens in the early stage of wearing the prosthetic eye. As the wear time increases, the conjunctiva becomes less sensitive and the symptoms will gradually decrease. To reduce these symptoms, remove the prosthetic eye piece daily before bedtime, apply antibiotic eye ointment, and use eye drops containing sodium glassate to lubricate the conjunctival sac and reduce friction. 2. Lower eyelid relaxation and eye piece dislodgement: For patients who do not have an eye seat implant, the prosthetic eye piece that needs to be worn is thicker and its long-term compressive effect can cause relaxation of the lower eyelid and shallowing of the lower fornix, resulting in displacement of the eye piece and easy dislodgement. Therefore, for patients after eye removal, it is recommended to implant an eye seat and then wear a lighter prosthetic eye piece to prevent the above complications; for patients who have already had the above complications, they can be corrected through surgery. 3. Supraorbital depression and ptosis: Due to gravity, the soft tissues and eye seats in the orbit will gradually shift downward, causing supraorbital depression and secondary ptosis, which affects aesthetics. This condition can be corrected by replacing the prosthetic eye piece, or by reconstructive surgery.
