5000, relevant experts believe that laser treatment of myopia can't be done, try not to do it, and don't "cram for the time being". In order to ensure the safety and effectiveness, excimer laser treatment of myopia requires that the patient's refractive state is stable before operation and the corrected vision is above 0.5. Accordingly, the best age for surgery should be 25 to 35 years old. Teenagers under the age of 65,438+0.8 are in the physical growth period, and the diopter of their eyes is unstable. If you operate blindly, your vision is likely to deteriorate after one or two years, which will seriously affect the expected curative effect and fail. In addition, excimer laser therapy for myopia was first used in clinic by American doctors in 1985, and it has developed rapidly in recent years. It was introduced to China in the early 1990s, and it has only been 265,438+0 years since its clinical application. It will take a long time to observe whether there are sequelae. You can dip in water or swim after operation, which is not serious to your daily life. If I were you, I would choose a combination of clearing my eyesight, improving my eyesight and myopia for treatment. No side effects. In the future, this method will only be considered after scientific demonstration and practical test, and there is no problem with laser treatment. The following complications are easy to occur during and after operation: 1, corneal flap eccentricity, corneal flap dislocation, corneal flap wrinkle, corneal interlayer debris or blood residue; 2. The laser cutting deviates from the center, and the corneal knife cuts through the cornea; 3, postoperative lifelong glare and glare: myopia is more common in high altitude areas, and things have halos; 4. Undercorrection or overcorrection: If this happens, re-operation, and the effect after the second operation is not ideal; 5. Vision rebound: especially in patients with high myopia, vision began to decline several years after surgery; 6, the best corrected vision decline: the vision that can be achieved when wearing glasses can not be achieved after surgery; 7. Dyslexia, dry eye, decreased corneal sensitivity and pain; 8. Irregular astigmatism: Almost all patients have irregular astigmatism in different degrees after operation. 9. Corneal infection, diffuse interlaminar keratitis, central corneal island formation: 10, peripheral corneal degeneration or scar formation, central corneal pigmentation.
