Myopia surgery can only be performed with four conditions

Abstract: myopia is a common eye disease, which has a great impact on vision. According to the survey of the Ministry of education and the former Ministry of health, the myopia rate of primary school students in China exceeds 25%, nearly 70% of junior middle school students and 85% of senior high school students. The myopia rate increases at a rate of 8% every year, ranking first in the world.

many people choose to have surgery in order to take off their glasses, because it only takes more than ten minutes to help myopic people have bright eyes again. Can myopia be cured?

myopia is a common eye disease, which has a great impact on vision. According to the survey of the Ministry of education and the former Ministry of health, the myopia rate of primary school students in China exceeds 25%, nearly 70% of junior middle school students and 85% of senior high school students. The myopia rate increases at a rate of 8% every year, ranking first in the world.

nowadays, the most common method to treat myopia is excimer laser correction surgery (hereinafter referred to as “laser surgery”), but many people know little about this surgery, and there are some misunderstandings.

myopia is caused by the long anterior posterior diameter of the eyeball, the convex cornea and the inability of external light to converge accurately on the fundus. Laser surgery for myopia is to use the laser beam to change the curvature of the anterior surface of the cornea to correct ocular ametropia. Generally speaking, it is to “grind” a pair of appropriate glasses on the cornea, so that the external light can accurately converge and image in the fundus, so as to achieve the purpose of correcting myopia.

and

have four conditions for laser surgery. Not all people with myopia are suitable for excimer laser correction, which mainly depends on the state of the eyes. Generally speaking, four conditions can be met: 1 At least 18 years old; 2. The degree has been stable in the past two years; 3. Stable refraction for two years, good corrected vision and no other eye diseases; 4. There is no operation contraindication after examination.

any operation has risks. Although myopia surgery is a super minimally invasive surgery, it is no exception. Therefore, if patients choose myopia surgery to remove obstacles for passing the exam, they must avoid risks and put safety first. Experts said that although myopia surgery is very safe and reliable, it is not suitable for everyone. It has clear indications and contraindications, and must be strictly implemented.

therefore, each friend needs accurate preoperative examination for myopia surgery, and there are surgical contraindications, such as active eye diseases, glaucoma, corneal diseases, fundus diseases, systemic connective tissue diseases and autoimmune diseases, severe scar constitution, pregnant women, those who have high requirements for vision and have great concerns about the idea of surgery, etc, Don’t risk myopia surgery. Otherwise, it will greatly improve the operation risk and cause unnecessary sequelae.

and

the nursing after myopia surgery should be meticulous and serious.

and

1. Avoid operating the computer continuously for a long time and pay attention to the rest in the middle. Usually operate continuously for 1 hour and rest for 5-10 minutes. At rest, you can look far away or do eye exercises. Never “keep your eyes fixed”, and pay attention to frequent and complete blinking. Frequent blinking can reduce the time of eye exposure to the air and avoid the evaporation of tears.

2. Eat more fruits, especially citrus fruits. You should also eat more green vegetables, grain, fish and eggs. Drinking plenty of water can also help reduce dry eyes. Keep good living habits, get enough sleep and don’t stay up late. Adjust the distance and position of the fluorescent screen. The recommended distance is 50-70cm, and the fluorescent screen should be 10-20cm lower than the horizontal position of the eye, with a downward viewing angle of 15-20 degrees. Because the angle and distance can reduce the demand for refraction and reduce the probability of eye fatigue.
