What are the risks of corneal thinning after laser surgery for myopia?

Although the laser surgery for myopia is a laser cutting of the cornea and thinning the cornea, the current laser minimally invasive surgery is carried out without destroying the stability of the corneal tissue structure and within the range of safety values, and the doctor will estimate that the postoperative corneal thickness is not lower than the corneal safety value before the operation, so as to ensure the postoperative safety and the effect after the operation. Therefore, even after myopia laser surgery, the corneal protection function is very safe.

The corneal thickness after surgery will definitely be within a safe range, and the doctor will estimate that the corneal thickness after surgery will not be lower than the corneal safety value to ensure postoperative safety and postoperative results. Therefore, even if you have myopia laser surgery, the corneal protection function is very safe, and you can go to a professional eye hospital for examination first.

Before the surgery, your doctor will do a series of tests to confirm that your cornea is suitable for the surgery and that it is safe if you are eligible. Corneal thinning is also allowed, so don't worry.

If you want to take off your glasses for myopic eyes, there is only one way to do it. Myopia is a routine operation in ophthalmology, which is mainly divided into two types according to different surgical methods, the first is corneal refractive surgery, which changes the radius of curvature of the cornea or the thickness of the cornea, including excimer laser surgery and femtosecond laser surgery. The second type of intraocular refractive surgery, which changes the refractive state of the eye by implanting an intraocular lens in the eye, thereby correcting myopia, is currently commonly used by intraocular lens implantation with phakic eyes, or lens exchange.

These methods can be used to correct myopia, so that patients with myopia can remove their glasses, and the results are very good. You can wait until you are old enough to go to a regular eye hospital for a consultation about laser surgery**.

Generally speaking, the corneal thickness of normal people is 500um-600um, and when laser surgery is performed, a corneal flap will be cut with a lamellar knife, the thickness of this corneal flap is about 160um, and then every 100 degrees of myopia needs to be vaporized by laser for about 12um, and the thickness of the corneal basal layer (excluding the corneal flap) after ** should be retained at least 250um, that is to say, the remaining cornea of each patient after laser surgery must be retained to a safe thickness of 410um (corneal flap + corneal basal layer).

If the thickness of the cornea is not reached, then myopia surgery cannot be performed.

In addition, the following conditions must be met for myopia surgery.

1. Must be over 18 years old.

Myopia under the age of 18 is still in the stage of vision development. Myopia can be treated with medication**. It is generally recommended to take two packs of Joy Vision Nutrients a day, and insist on taking it for a period of time, the degree of myopia will be reduced, the vision will be improved, and there is no need for adult surgery.

2. The degree of myopia is between 100-1500 degrees, the degree of astigmatism is within 400 degrees, and the vision is stable for more than two years.

3. There are no other ophthalmic diseases, which do not affect the postoperative recovery.

After preoperative examination, only those who meet the requirements of surgery can be operated.

If the corneal thickness is not enough, laser surgery is not recommended, and the remaining corneal thickness after surgery must be within a safe range, and lens implantation surgery can be selected.

Generally speaking, every 100 degrees of myopia requires 12 microns of corneal thinning, and the cornea needs to be at least 410 microns of safe thickness after surgery.

Myopia surgery is irreversible, and even if you are not satisfied with the surgery, it is impossible to return to the previous one. In particular, most of the people who undergo this surgery are young people, and they are in the process of starting a career, and if they are not careful, it will affect the development of their lives, so they must choose carefully.

No, the principle of laser surgery is to reduce the thickness of the cornea in the form of laser, the thickness of the center of the cornea is 500 microns, and 300 microns need to be retained.

Surgery can also be performed on thin corneas, but only after a detailed examination to ensure that there are no contraindications to surgery. What is your degree of myopia? If the cornea is thin, surgery on the surface of the eye can be chosen, and it will be decided after visiting the hospital for examination.

When you ask these doctors if it's safe, they will tell you: it's safe. No matter what level of hospital, no matter what kind of authority, these surgeons in China cannot surpass Taiwan. Cai Ruifang's fame and prestige.

However, Taiwan has announced the "sealing of the knife" of Tsai Ruifang and officially warned those who are preparing to undergo surgery:

Loss of night vision is common in 99% of people who have undergone surgery, and the chance of dry eye syndrome is about 60% to 70%.

These symptoms will follow you for the rest of your life (in the past, we said that these symptoms would not be there in half a year).

Some people are willing to use refractive surgery to achieve the purpose of removing their glasses, what should they do? Then you can only be prepared to accept the risks that come and calmly accept the immediate or long-term complications of surgery.

As long as you enter the implementation process of "excimer laser lamellar corneal surgery", all future troubles have nothing to do with the law and have nothing to do with the outcome that can be recovered. Please remember the last sentence Cai Ruifang said in an exclusive interview with "People**": Since you want to accept this method, you may have to face unknown risks after this surgery, which is not as simple as doing a cosmetic surgery.

Myopia eye surgery requires a series of preoperative eye examinations to determine whether myopia eye surgery can be performed. At present, myopia eye surgery has been relatively mature. The success rate of myopia eye surgery is also quite high.

Due to the existence of individual differences. It is recommended to go to a hospital or a regular medical institution for a series of examinations for myopia eye surgery before surgery. Based on the results of the examination, the ophthalmologist analyzes them to determine whether they are suitable for myopic eye surgery.

I'm cured, it's been fine for three years! Do what you want, no one can tell if it's harmful! But hesitation is the greatest harm!

Harm of laser surgery: Myopia eye treatment surgery is to remove the cornea of the eyeball and change the curvature and thickness of the cornea, so that the focus of light falls accurately on the retina. Laser**Myopia can cause uncomfortable symptoms such as swollen eyes, tiredness, headaches, etc.

**The best way for myopia is daily care, you can eat more eye-friendly foods in your diet, mainly milk and its products, shellfish, bone meal, beans and soy products, egg yolks and dark green vegetables, which are good for the eyes, and then drink with Zheng 9 flavor pupil tea to help restore vision.

Laser** Dangers of myopia: The cornea of the eye must remain transparent, so that the excellent world outside can be reflected on the retina. There are no blood vessels on the cornea, and its metabolism is completed by the watery eye fluid in the spongy tissue and the blood vessels around the cornea.

When the cornea is covered by these hyperplastic blood vessels, the transparency is obstructed, and the view of objects becomes blurred, especially shadows. Drinking 9 Flavor Pupil Kernel Tea has a nourishing and maintenance effect on the eyes, brightens the eyes, clears away heat and detoxification, lowers intraocular pressure, and is also helpful for restoring vision.

For those with a corneal center thickness of less than 500 m, if the patient is highly myopia, you should pay attention to the cutting depth of the corneal center, you are suitable for LASEK surgery in this situation, you said "super xx" I'm sorry I haven't heard of it, the total corneal thickness of EK should be at least 360um or more, that is, the thickness of the corneal subepithelial basal layer should be at least 300umYours is just right, and it should be possible to do it if all else is normal.

Guidance: The LASEK method is to use an epithelial knife to cut out an epithelial flap with a thickness of 60-80 microns, a diameter of 8-10 mm, and a curvature of 30 degrees of pedicle, and then use an excimer laser to grind in situ under the precise control of the computer to change the refraction of the cornea to achieve the purpose of correcting vision and astigmatism, and then repositioning the epithelial flap. After 4 days, it is replaced by a new epithelium, and the problem of aberration, glare can be solved after the surgery. Because the thickness of the epithelial flap is 60-80 microns, it is more suitable for patients with thin corneas.

Complications, complications will occur more or less in the future, all surgery is not recommended!

Laser surgery is a ** for those who have a high prescription! At present, the incidence of myopia in China is more than 30%, and among middle school students, the incidence rate is more than half, and the incidence rate among college students is as high as 74%! In response to this problem, a method of myopia has emerged:

Laser surgery has been performed on millions of patients in China since the first LASIK surgery was performed in 1997. LASIK has been able to improve patients' vision in a short period of time, attracting thousands of people who are eager to remove their glasses. However, the vast majority of these people are people who know nothing about the procedure, and why do so many doctors still wear glasses in the eye centers of many hospitals?

Why don't you have such a good surgery? It wasn't until a few months ago that I figured out that it was a conspiracy! Myopia surgery is the biggest conspiracy in the medical community in recent years!

Does myopia eye surgery cause the cornea to detach?

There is a possibility of falling off, but it cannot be said that it is very easy.
