Surgery can only be performed after the vision is stable. The standard is: the vision has not changed within two years, and teenagers are completely unsuitable.
After the operation, you must not open your eyes for 24 hours. If you open your eyes, your eyes will sting. So before you decide to have an operation, you must make an appointment with your family or good friends, because after the operation, you can't let others take you home with your eyes open.
Within 3 months after operation, read less books, watch less TV and watch less computers. You can't play computer games. Also avoid glare and glare. In short, use your eyes less, or your eyesight will drop sharply.
Even after two or three years of surgery, vision may still decline, so we must persist in not letting our eyes get tired. Once you feel tired, you must close your eyes and rest.
Laser scalpel is also a kind of scalpel. No matter how advanced the laser technology is and how perfect the doctor's operation is, it is inevitable to damage the cornea. "Injury" means that when cutting the cornea, it will produce some very small cracks, which is inevitable. These tiny cracks can cause corneal fragility and pain. You should not rub your eyes hard for several years after operation. If you have sand or dust in your eyes, you can only remove it by tearing or blowing. People whose corneas are too thin are not suitable for surgery. People with high myopia need to cut off more corneas, and the operation is risky, and the cornea is thinner and more fragile after operation, which is not recommended.
After the operation, even if it is well protected, some people's eyesight may still decline because of different constitutions. Oral medication containing bilberry extract and sodium hyaluronate eye drops can effectively relieve it. Bilberry extract is used to dilate retinal blood vessels and promote retinal microcirculation. There is a kind of "Difrarel" made by Laboratoires LEURQUIN MEDIOLANUM, and its main components are Vaccinium myrtillus anthocyanin (VMA) and β carotene. Delivery in famotidine tablets is quite expensive. The price of 20 tablets is 70 yuan RMB, with an average of 3-6 tablets per day. Sodium hyaluronate eye drops are specially used to repair corneal injury. There are "Federated Sparkling Crystal" produced by Zhuhai Federated Pharmaceutical Co., Ltd. and "Aili Eye Drops" imported by Kanda Pharmaceutical Co., Ltd. in Japan, but these drugs should be in accordance with the doctor's advice and should not be used indiscriminately. The reason why I wrote it here is to let everyone have something to say to the doctor. The doctor thinks you are very professional, so he dare not fool you. If you act like you don't know anything, you will be pushed around by him.
Things in China have always been like this. People think you are very professional and have a good knowledge of this business. He won't dare to fool you, but work hard and the result will be much better!
The final effect of any operation is: five points depend on operation and five points depend on maintenance. Maintenance after operation is as important as the operation itself!
