Popular Science: What should you do if an “accident” occurs during myopia surgery?

You never know how big a person's imagination is.

For example, regarding myopia surgery, some people are worried about what will happen if they accidentally blink or move their eyeballs during the surgery? Will they go blind? What will happen if the power suddenly goes out during the surgery? These are some of the most mind-boggling questions. Today, let's talk about them briefly.

Blinking or eye movement during myopia surgery

There is no need to worry about this, because you cannot blink during the operation. Before the operation begins, the doctor will put an eyelid opener on your eyes. Yes, it is a device that helps you open your eyelids. Therefore, during the operation, you will not be able to blink even if you use all your strength. So how long will this state last? At most, it will only take a few minutes.

Zhang Qingsong, a member of the Refractive Subcommittee of the Ophthalmology Committee of the China Association of Non-Public Medical Institutions and deputy chief physician of the refractive department of the Aier Eye Hospital affiliated to Wuhan University (Aier Eye Hospital Group Hubei General Hospital), said that the current myopia surgery equipment is very "smart". During the operation, most of the surgical equipment has positioning and tracking functions, and the eyeball is tracked through the iris positioning system. Once the cornea deviates from the laser, such as a slight rotation of the eyeball, the laser equipment will start the positioning system for tracking, and if the rotation is large, the laser will automatically stop. So don't be nervous, just cooperate with the doctor.

The power went out during the operation.

Imagine that you are lying on the operating table and suddenly there is a click and the power goes out...

Don’t be afraid! Don’t worry, this situation will not happen during myopia surgery.

The power distribution in the operating room of each hospital is very strict. Even if there is a power outage, there will be a backup power supply. Each hospital has an emergency lighting system to ensure the smooth completion of the operation. In addition, the key to myopia surgery is the implementation of laser, which takes only a few seconds, and the time on the operating table is only a few minutes. During this period, a continuous power supply device will be used to ensure the smooth completion of the operation.

"Accident" occurred during myopia surgery

Myopia surgery is not for everyone. Before each surgery, a strict preoperative examination is required to screen those who are suitable for the surgery and filter the risks of the surgery. In this process, your postoperative vision recovery can also be predicted.

In fact, all the worries are due to lack of understanding. Ophthalmologists and their families all perform myopia surgery. If there are risks in surgery, it is the same for everyone. If you are really worried, you might as well ask your friends who have already had myopia surgery to understand their feelings.
