Sequela of eye laser surgery?
Any operation has certain complications and risks. The risks and complications of myopia surgery are relatively few, as follows: 1. Dry eye: Dry eye is very common now, and many people do not have surgery for dry eye. Because more people watch TV, computers and mobile phones, the incidence of dry eye is getting higher and higher. However, after myopia surgery, dry eye may get worse, and those without dry eye may get dry eye. Not everyone will suffer from dry eye after surgery. Dry eye caused by surgery can be recovered, which usually takes about 3-6 months, and can be recovered by taking some medicine. 2. Refractive regression: related to individual differences. Refractive regression refers to myopia after a period of time. Some people have nothing to do after surgery. Some people will be nearsighted again a few months after operation or even 1-2 years. The regression probability of high myopia is relatively higher than that of low myopia. You can also wear glasses when you go back. If you don't want to wear glasses and your cornea is thick enough, you can have a second operation. 3, glare, poor vision at night: For example, when you go out to see the opposite car at night, the halo may be large, sometimes the patient will be affected when driving, and this will happen to individual patients. As time goes on, this phenomenon will become weaker and weaker, and it can be recovered slowly. With the continuous updating of excimer laser machines, this complication is becoming less and less. 4, infection: It is a very serious complication, and any operation is afraid of infection. Once infected, it is very troublesome to deal with. Therefore, it is necessary to carry out strict preoperative examination. Generally, anti-inflammatory drugs are used 3 days before operation, and enough anti-inflammatory drugs are needed in the eyes before operation. A series of procedures such as surgical procedures and disinfection should be strictly followed during the operation. 5, keratoconus: it is a more troublesome complication, and it is a congenital disease. When you do the inspection, you must strictly control it. If you find this factor, don't do surgery. Some keratoconus were not shown during the examination, and the development of keratoconus would be accelerated after the operation. Therefore, we must have a strict examination before operation and ask about the medical history. Ask whether the refractive index has changed in recent years and whether astigmatism has developed greatly. Once keratoconus appears, it is more troublesome to correct it, ranging from wearing RGP glasses to serious ones that may eventually require corneal transplantation. Therefore, surgical indications should be strictly controlled.
