Why do some people prefer to wear glasses instead of undergoing surgery? I didn’t expect it to be this!

Many people are eager to correct their vision through myopia surgery, but they are deterred by various concerns. Can myopia surgery be done? Today, the editor summarizes and answers 5 common concerns of patients about myopia surgery. See if you think so too?

Question: Myopia surgery is a newly invented new technology and is not mature yet?

A: In fact, laser myopia surgery has been performed clinically for decades, and the technology has been continuously updated over the past few decades. Early mechanical knives have gradually been replaced by lasers, achieving "knife-free surgery". It has been widely performed at home and abroad and has been recognized by regulatory authorities and experts and scholars, which is enough to show that it is a mature and reliable technology.

Question: Eye surgery is like walking on a needle tip, is it extremely risky?

A: When thinking about having surgery on the eyes, many people who are more involved feel nervous. However, corneal laser myopia surgery has now achieved automated knife-free surgery, with laser replacing mechanical knife and the surgery being completed by equipment. During the operation, the eyelid opener will open the eyelids, and the patient needs to stare at one point to avoid eye movement. The infrared tracking system will evaluate the position of the eyeball, and if it deviates too much, the operation will be quickly suspended.

Question: The effects of myopia surgery are difficult to maintain, and I will become myopic again after two years?

A: Myopia surgery is to correct the patient's current myopia. Patients who have undergone surgery may still have myopia in the future. However, generally speaking, myopia tends to be stable after adulthood, and good vision can be maintained for a long time under the premise of standardized and reasonable eye use. The preoperative examination will evaluate the patient's eye condition. If there are risk factors that affect the stability of postoperative vision, surgery may not be allowed, and the risk will be excluded from the surgery.

Q: Will my eyes become dry and itchy after myopia surgery?

A: Generally speaking, short-term symptoms such as dry eyes and itching may occur after myopia surgery. The severity and duration vary from person to person and will recover over time. Using artificial tears after surgery can help alleviate these symptoms.

After the operation, you need to pay attention to proper eye use, use your eyes at close range for about 40 minutes, close your eyes to rest or look into the distance for about 10 minutes to give your eyes a rest.

Q: Will myopia surgery affect my night vision?

Answer: For most people, myopia surgery will not have a significant impact on night vision, nor will it affect normal life and work.

Liu Hongting, PhD, associate chief physician, master's supervisor, and deputy director of the refractive department of Wuhan University Aier Eye Hospital (Aier Eye Hospital Group Hubei General Hospital), said: From the principle of surgery, myopia surgery is performed in the center of the cornea, which has a certain range. When the light becomes weak at night, the pupil will naturally become larger. If it is large enough to approach or even exceed the surgical area, night vision may decrease slightly. This is a normal phenomenon and generally does not affect normal work and life. And the doctor will also recommend the appropriate surgical method based on the individual's eye condition and needs, so there is no need to worry too much.
