Routine eye examinations should be performed before surgery,

Although excimer laser refractive corneal surgery is fast and painless, postoperative self-care plays an important role in postoperative recovery, curative effect of the surgery, and prevention of complications. It must be given full attention because Different surgical methods, post-operative care are also different.

(1) Eye closure after PRK surgery, pain and foreign body sensation after 1 hour, some people have tears and nasal congestion are normal postoperative reactions. Some people have strong pain. They can take stability and painkiller tablets. If the pain is severe and gradually worsens, they should go to the surgery hospital for examination. Do not open the package and handle it by yourself. The first day after the operation should be continued for two days after the dressing change, and the pain will gradually reduce to disappear. If the pain gradually worsens, it should be checked at the surgical hospital in time. The third day after surgery should be checked at the hospital. Other problems can be normal activities. After LASIK, there is only a foreign body sensation or mild pain. Do not enclose it. Wear a transparent eye mask for 1 day. You should go to the hospital for examination on the first day after surgery. You can move normally without any other problems, but you should avoid rubbing hard for three months. Eye and fight. We encountered a patient who had played basketball 1 week after surgery and was pierced into the eye with the other's fingers. As a result, the corneal flap was opened. Fortunately, he rushed to the hospital for reduction in time, but fortunately did not cause serious consequences.

(2) Strictly follow the doctor's order to conduct regular review at 1 week, 2 weeks, 1 month, 2 months, 3 months, 6 months, and 1 year after surgery.

Weak function, there may be some hyperopia, insufficient correction of myopia, astigmatism, glare and other symptoms, you should wait patiently for observation, do not rush to surgery again.

(5) Excimer laser refractive corneal surgery only changes the corneal refractive power, as if wearing a pair of invisible glasses, it has no preventive and therapeutic effect on other eye diseases, especially for patients with progressive myopia and high myopia, still need to pay attention Prevention and treatment of complications.
