Abstract: to improve the degree of myopia, you must develop good eye habits, watch less TV, play less computer, and eat more vitamin B and vegetables. Be careful not to wait until you feel tired. Instead, you should rest for 10-15 minutes every hour or so, or look at the green trees or vision outside the window, or do eye exercises., How can ability maintain myopia degree not to increase. According to experts, myopia has plagued nearly one-third of Chinese people in recent years. According to statistics, the number of myopia in China has reached nearly 400 million. The rate of juvenile myopia is as high as 40%. Myopia brings great physical and psychological harm to teenagers, but the prevention of myopia is not easy. How can we keep the degree of myopia from increasing? At present, the most effective method is femtosecond laser therapy., How to keep the degree of myopia from increasing: in the treatment of myopia with femtosecond laser, the main change is to make corneal flap with laser instead of mechanical lamellar knife in traditional myopia surgery. How to keep the degree of myopia from increasing? The safety performance of traditional myopia surgery has been very good. However, due to the flap making by mechanical corneal lamellar knife, the possible infection caused by mechanical corneal lamellar knife can not be avoided. The charm of femtosecond laser myopia surgery, laser valve making and knife free surgery in Shanghai eighth five year hospital shows the safety incisively and vividly., 1. Femtosecond laser is a kind of laser that operates in the form of pulses. Its duration is very short, only a few femtoseconds. A femtosecond is 10-15 seconds, that is, one millionth of a second. It is thousands of times shorter than the shortest pulse obtained by electronic methods. It is the shortest pulse that human beings can obtain under experimental conditions., 2. Femtosecond laser also has very high instantaneous power, which can reach one million gigawatts, 100 times more than the current total power generation in the world. The femtosecond laser can focus on a spatial area smaller than the diameter of the hair, making the intensity of the electromagnetic field several times higher than the force exerted by atoms to check the electrons around them., How can

how to keep the degree of myopia from increasing:
femtosecond laser in the treatment of myopia surgery, the main change is to use laser to replace the mechanical lamellar knife in traditional myopia surgery to make corneal flap. How to keep the degree of myopia from increasing? The safety performance of traditional myopia surgery has been very good. However, due to the flap making by mechanical corneal lamellar knife, the possible infection caused by mechanical corneal lamellar knife can not be avoided. The charm of femtosecond laser myopia surgery, laser valve making and knife free surgery in Shanghai eighth five year hospital shows the safety incisively and vividly.
