Abstract: the success of myopia surgery depends not only on the recovery of vision, but also on the visual quality, including the distance, the comfort of daytime vision, the balance of both eyes, and the sense of three-dimensional. Now myopia surgery can do personalized cutting according to the specific situation of the patient’s eyes. Therefore, the total satisfaction has reached 97% – 98%.
1. How many methods are there for myopia surgery?
answer: at present, there are mainly two kinds of myopia treatment surgery: one is excimer laser surgery; The other is posterior chamber refractive intraocular lens implantation, which is often called refractive lens surgery. Refractive crystal surgery is called “addition surgery” in the industry, and excimer laser surgery is called “subtraction surgery”. Refractive lens surgery refers to the operation of adding intraocular lens into the eye and placing the lens in the safe area in front of the lens of the human eye, so as to achieve the effect of correcting visual acuity. Excimer laser is to correct myopia by cutting the corneal stroma under the corneal flap to reduce the corneal curvature of the pupil. This is also the most commonly used method at present. There are two main ways of myopia surgery at present!
2. How high is the success rate of myopia surgery?
A: the success of myopia surgery depends not only on the recovery of vision, but also on the visual quality, including whether the distance and daytime vision are comfortable, whether the eyes are balanced, and how three-dimensional feeling is. Now myopia surgery can do personalized cutting according to the specific situation of the patient’s eyes. Therefore, the total satisfaction has reached 97% – 98%.
3. What are the reasons affecting the success of the operation?
A: what worries professionals most is that excimer laser surgery can be done everywhere, but the supervision of equipment and surgical personnel is very weak. For example, the most basic optometry, there are no professional optometrists in many places, and the information obtained by the machine is not accurate. It is conceivable that there are surgical problems. In addition, the blade is not updated as required, and medical institutions should strictly implement the regulation that one knife can only operate on one patient.
4. Will there be complications after operation?
A: complications mainly refer to the adverse effects directly caused by the operation, mainly including the following three situations: inflammation after the operation, haze after the operation, keratoconus after the operation, and even blindness. However, these situations account for only a small part at present.
5. Will myopia stop after surgery?
A: at this stage, all surgical treatment methods for myopia belong to “symptomatic” treatment, not “cause” treatment. For example, excimer laser surgery can only “correct vision”, but not “cure” myopia. For people with high myopia, myopia may be repeated. And after surgery, if you don’t pay attention to eye habits and eye hygiene, your vision will also decline again. If eyesight drops again, with current technology, you can do a second excimer laser operation or wear contact lenses. In the United States, 10% of postoperative patients wear contact lenses.
6. Is anyone suitable for surgery?
answer: excimer laser surgery can not be done by anyone. The patient’s cornea must retain sufficient thickness and mechanical strength to ensure that there will be no problems after operation. If the degree of myopia is large or the cornea is thin, and sufficient corneal structural stability cannot be retained after operation, the operation should not be performed. In addition, the following patients should not do it: for example, myopia patients under the age of 18 (because their refractive system is not developed); The degree of myopia is unstable, and there are still people who have deepened more than 50 degrees year by year in recent years; Active eye diseases (such as inflammation, glaucoma, severe dry eye, etc.); The central corneal thickness is less than 480 microns; There are other serious eye diseases or autoimmune diseases, scarring constitution and severe diabetes. People with myopia above 1250 degrees are especially not suitable for it.
7. What should we pay attention to before operation?
answer: before the operation, we must prepare according to the doctor’s requirements, keep the eyes in the best state, don’t stay up late and relax, stop wearing contact lenses two weeks in advance, and require antibiotic eye drops three days before the operation. Because there are many bacteria and other microorganisms in normal conjunctival sac, preoperative medication can greatly reduce the chance of infection. Some patients come to have surgery. We can only ask him to order antibiotic eye drops many times a day, but we don’t advocate this.
8. What should we pay attention to after operation?
answer: everything is not good after the operation. 1. Eye protection: the first week after operation is the key period to avoid eye rubbing and eye water. It is best to dry clean your hair in the barber’s shop within one week; 2. Medication: according to the doctor’s requirements, improper medication after operation will also affect the operation effect; 3. Reexamination: make sure to follow the doctor’s advice, especially regularly reexamine the intraocular pressure to avoid the occurrence of hormonal glaucoma; 4. Eye use: wound healing requires a process, and there will be a recovery period after operation, so you should pay attention to rest within a week. It is best to avoid long-term and high-intensity eye use within one month; 5. Driving: try to reduce driving at night within a month, and pay attention to driving during the day; 6. Exercise: within one week after operation, avoid sweat flowing into your eyes during strenuous activities. Avoid sports that may cause impact on the head and eyes, especially for patients with high myopia. Due to their poor fundus state, they should pay more attention to protection. Swimming is prohibited within 40 days after operation; 7. Make up: it is best not to make up within three days after operation to avoid touching the eyes. It is best not to draw eyeliner and apply mascara in two weeks.
9. Do you need to face the computer for a long time after operation? Will it affect the postoperative effect?
A: most of the patients receiving excimer surgery are over the age of 18. The degree of myopia is relatively stable. Facing computers and television after surgery, it generally will not affect the effect of surgery, but they should also have a proper rest and don’t be too tired. Eat more fruits, especially citrus fruits. You should also eat more green vegetables, grain, fish and eggs. In addition, drinking plenty of water can also help reduce dry eyes.
