Is femtosecond laser surgery safe

summary

The emergence of femtosecond laser makes it the first time for human beings to observe this ultra fast motion process at the atomic and electronic level. Based on these scientific discoveries, femtosecond laser has been widely used in physics, biology, chemical control reaction, optical communication and other fields. It is particularly worth mentioning that femtosecond laser has its unique advantages and irreplaceable role in early diagnosis of pathological changes, medical imaging and biological detection, surgical treatment and the manufacture of ultra small satellites due to its fast speed and high resolution. Is femtosecond laser surgery safe.

It can be divided into public hospitals and specialized hospitals. The operation equipment is the same. The price of private specialized hospitals is more expensive, but the service is better and more convenient. The price of public hospitals is relatively cheap, but the appointment queue will take a lot of time. As an office worker, I didn't have much time, so I made an appointment for an operation in a private eye hospital. And private hospitals will also have many kinds of discounts. Don't forget to scan wechat, and then make an appointment online in advance. If you have a student ID card and a teacher ID card, please show them. After calculation, you can get a discount of several hundred yuan for the operation fee.

The nurse will clean your eyes, and then apply anesthetics;

Femtosecond laser is a kind of laser that operates in the form of pulse. Its duration is very short, only a few femtoseconds. A femtosecond is 10 to the negative 15th power second, which is 1 / 1000 trillion seconds. It is thousands of times shorter than the shortest pulse obtained by electronic methods. This is the first characteristic of femtosecond laser. The second characteristic of femtosecond laser is that it has very high instantaneous power, which can reach one million gigawatts, 100 times more than the total power of the world
