Is it really safe to spend tens of thousands of dollars on myopia surgery?

Nowadays, more and more people have taken off their glasses through myopia surgery. However, some friends are still hesitant. When they think about having surgery on their eyeballs, they feel inexplicably nervous. They worry about its safety, its sequelae, and they don't know which surgery method is suitable for them...

So, should you have myopia surgery? Can you do it? Don't worry. Before you understand the following knowledge about myopia surgery, I advise you not to do it lightly.

01. Is myopia surgery safe?

Let me say it again today about the safety of the surgery.

First of all, not everyone can undergo myopia surgery. The country has stipulated strict surgical indicators, and Aier Eye Hospital has formulated higher Aier standards based on national standards. Through strict preoperative examinations, it determines whether myopic patients can undergo myopia surgery and which type of myopia surgery they can undergo. It is not a random decision.

Secondly, whether it is laser myopia surgery or ICL lens implantation, it is performed on the front part of the eye and will not touch the retina and other parts of the back of the eye.

02. Will my eyes become dry and itchy after myopia surgery?

Zhang Qingsong, deputy chief physician, member of the Refractive Subcommittee of the Ophthalmology Committee of the China Association of Non-public Medical Institutions, and director of the Refractive Department of the Aier Eye Hospital Affiliated to Wuhan University (Aier Eye Hospital Group Hubei Headquarters), explained: Generally speaking, dryness or itching will not occur after myopia surgery. If this happens, it may be caused by dry eyes or keratitis, and you should go to the hospital for examination.

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.

03. Will myopia surgery affect night vision?

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

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 larger to approach or even exceed the surgical area, night vision may be slightly reduced. This is a normal phenomenon and generally will 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.

04. Will myopia surgery be painful?

Myopia surgery is performed on the cornea of ​​the eye, not deep into the eyeball. There are no blood vessels on the cornea, only nerve endings, and topical anesthetic eye drops will be applied before the surgery, so there is almost no pain during the operation.

05. How is myopia surgery performed?

Take laser myopia surgery as an example. When you lie on the operating table, the nurse will drip anesthetic eye drops. Then, the instruments on the operating table will slowly approach your head. The eye sockets will be opened by the eyelid opener. A green dot will appear in front of your eyes. It will take about a few seconds to tens of seconds. Stare at the green dot above, and the laser will start cutting. During this time, the cornea will be carved into a beautiful arc, and the world will become clear from then on. It is inevitable to be nervous during the operation. The doctor will gently comfort you. Follow the doctor's instructions and the operation will be completed quickly. The whole process takes about five minutes.

06. How to choose the surgical method that suits you?

Laser myopia surgery requires cutting of the cornea, so there are certain requirements for corneal thickness. The higher the degree of myopia, the more cornea needs to be cut. In addition, the remaining corneal thickness must be within a sufficiently safe range. The upper limit of myopia that can be corrected is 1000 degrees.

Lens implant myopia surgery can overcome the limitation of corneal thickness. If the conditions are met, patients with myopia within 1800 degrees can regain clear naked eye vision through this surgery. Since the degree of myopia that can be corrected is higher, patients with high myopia and super high myopia choose this surgery more often.

It is not "I choose whichever I want" or "I choose whichever I like", but I choose the one that is suitable first and then the one I like. No matter how much you like this type of surgery, if your eye conditions do not meet the requirements, you can only choose another one.

Liu Hongting, PhD, associate chief physician, master's tutor, and deputy director of the refractive department of Aier Eye Hospital affiliated to Wuhan University (Aier Eye Hospital Group Hubei General Hospital), reminds: Only after the preoperative examination of myopia surgery can you determine the myopia surgery method that is suitable for you. If you are only suitable for a certain type of surgery, then there is no need to worry about it. If you are suitable for most surgeries, the doctor will discuss and determine the surgical method based on your surgical purpose, eye needs and your favorite surgical method.
