In recent years, with the popularization of electronic devices and the increase in study pressure, people use their eyes longer and longer, but the maintenance of their eyes has not been improved. This has formed a problem that we have found in both adults and teenagers. , the number of people wearing glasses has greatly increased, and the vision problems of our country's teenagers have become more serious.
In recent years, full femtosecond laser surgery for the treatment of myopia has been favored by more and more people. So what exactly is full femtosecond laser surgery? How is it implemented? What impact does it have on the human body? Let’s see What do you know?
Full femtosecond is the common name for laser surgery to treat myopia. Its full name is small-incision femtosecond laser corneal stromal lensectomy. Its implementation process is to use laser to thin the corneal stromal layer of the eyeball, and then make a lens. , a surgical method that finally removes the lens from a small corneal incision, has been widely accepted and is used as the preferred method to treat astigmatism and myopia.
However, it should be noted that not all people with myopia and astigmatism are suitable for full femtosecond surgery. The following situations are more suitable for surgery:
1. The patient is unwilling to wear glasses for a long time and has the desire to take off the glasses.
2. It is best if you are under 18 years old or underage. The effect will gradually weaken as your age increases.
3. The condition of the eyes is relatively stable. One year before the surgery, the degree of myopia did not exceed 50 degrees, the myopia did not exceed 600 degrees, and the astigmatism did not exceed 500 degrees.
The following situations are not suitable for surgery:
1. The cornea is too thin and cannot be easily thinned.
2. Suffers from eye diseases such as dry eye syndrome, Sjögren's syndrome .
3. Has glaucoma , cataract and other diseases.

For some people who are afraid of surgery, there is no need to worry about full femtosecond laser surgery. The surgical process is relatively fast and simple. The entire process is performed by laser and can usually be completed in about 15 minutes. In about a week, the patient The visual acuity can return to the best preoperative corrected visual acuity.
Although we can use full femtosecond technology for active and effective treatment after myopia or astigmatism, in daily life, the most correct way is to pay attention to the protection of vision and reduce the use time of electronic devices. Every two Carry out effective outdoor activities for hours, look out the window, learn eye exercises , relieve eye fatigue, develop good eye habits, use the correct eye drops under the doctor's advice, conduct regular fundus screening, etc. , these are effective measures to prevent myopia and maintain healthy glasses.
