How does myopic eye operation use medical insurance?

First, it is also called shortsightedness. Because this kind of eye can only see near, not far. When the eye is at rest, the parallel light from infinity passes through the refractive system of the eye, and then converges into a focus in front of the retina, forming an unclear image on the retina. The far vision is obviously reduced, but the near vision is still normal.

Second, the principle of the operation is to use excimer laser to cut the central anterior surface of the cornea, that is, to remove the elastic layer and shallow stroma of the epithelial layer, so as to reduce the curvature of the anterior surface of the cornea, increase the radius of curvature, reduce the refractive power, and move the focus back to the retina, so as to achieve the effect of correcting myopia, which is like grinding a pair of myopia spectacles on your cornea. Because of postoperative pain, long-term medication and easy regression, LASIK has been gradually replaced.

Third: myopia is caused by too long anterior and posterior diameter of eyeball, too convex anterior surface of ocular membrane, and external light can not accurately converge at the fundus. Excimer laser correction of myopia (LASIK / PRK) is a computer-controlled excimer laser, according to the degree of myopia and astigmatism in the pupil area of the corneal stroma layer etching, make the anterior surface of the cornea slightly flat. So that the external light can accurately converge on the retina of the fundus to achieve the purpose of correcting myopia.

matters needing attention

1. Within 24 hours: sleep in supine position is better, so as not to hurt the cornea. 2. There may be foreign body sensation or tears. Do not wipe with hands and pay attention to hygiene. 3. Don't wash your hair or shower. Do not use eye cosmetics. Within a week: 4. Wear an eye mask to protect your eyes when you go to bed, so as to avoid corneal flap displacement caused by external force. 5. No smoking, alcohol, betel nut, eat less stimulating food. Watch less TV, computers, books and newspapers to avoid eye fatigue. 6. In order to prevent dust or foreign matters from entering the eyes, you can wear sunglasses, flat lenses or eye protection masks to go out. 7. Do not swim or take a steam bath. Within one month: avoid doing strenuous exercise or activities that can hurt your eyes. Do not drive or operate dangerous machines. Life: pay attention to hygiene, avoid excessive eye use.
