Questions about myopia surgery: Will the laser used in laser myopia surgery go astray?

When it comes to myopia surgery, everyone becomes a "curious baby" and has many worries and questions. After all, it is an operation on such an important organ as the eye, so it is understandable that everyone is full of doubts about myopia surgery. Today, the editor will answer a few questions that everyone is concerned about, so that everyone can have a clearer and more scientific understanding of myopia surgery.

What should I do if I can't help blinking during surgery?

Blinking is a very normal physiological action, so some friends may worry that they can't help blinking during laser correction surgery, causing the laser to not hit the right spot and affecting the effect of the surgery.

You don't have to worry about this problem at all, because before the operation begins, the doctor will install a lid retractor to fix your upper and lower eyelids. The doctor's movements are very quick, usually before you react, they will install it for you. There is no discomfort when using the lid retractor to open your eyes.
The operation lasts several minutes until it is over, and you will not be able to blink during this process.

At this time, some people may be worried again. If they can’t blink, what if they accidentally move their eyeballs?
Don't worry about this. Generally speaking, there will be some waiting and preparation time after entering the operating room. At this time, the doctor or nurse will guide you to do fixation training. In addition, laser correction surgery is very fast, so generally, as long as you cooperate well with the doctor, it can be completed smoothly. Will the surgery hurt? What should I do if the laser is misaligned?

When performing myopia surgery, the doctor will use topical anesthetics to anesthetize the eye. Therefore, there is generally no obvious pain when laser corneal ablation or ICL lens implantation.

After the operation, the effect of the anesthetic disappears. Some people may experience a slight foreign body sensation and soreness, which is normal. Over time, the slight discomfort will gradually disappear. Will the laser be misaligned? Don't worry, myopia surgery is a highly automated operation. The eyelid opener will open the eyelids to prevent the patient from blinking and affecting the operation. During the operation, the patient needs to stare at one point to avoid eye movement. At the same time, the infrared tracking system will ensure that the eye is within the appropriate range. If it deviates too much, the operation will be suspended.

ICL lens implantation

You Changtao, deputy director of Zhengzhou Aier Eye Hospital and director of the refractive department, said: ICL lens implantation is a reversible surgical method that does not cut the cornea, has no requirements for corneal thickness, and avoids surgical risks such as dry eyes and glare. The correction range is wider than laser myopia surgery, and can correct myopia within 1800 degrees and astigmatism within 600 degrees. The implanted lens is a Swiss international patented product that can be permanently retained in the eye. If necessary, the lens can be removed or replaced.
