Ask about the surgical question of laser treatment for myopia, please be serious and grateful50

Laser myopia surgery.

Myopia is caused by the anteroposterior diameter of the eyeball being too long, or the lens is too convex and the outside light does not converge accurately in the fundus.

Excimer laser is an invisible ultraviolet beam with a wavelength of only 193 nanometers invisible to the human eye, which is characterized by large photon energy, extremely short wavelength, extremely weak penetration of tissues, will not penetrate into the eye, is only absorbed by the surface of tissues, and has no damage or damage to surrounding tissues.

Excimer laser corneal refraction** technology is a special extremely precise miniature lamellar cutting system. The surface tissue of the cornea is made into a pedicled corneal flap, and after the corneal flap is flipped, the excimer laser is used under computer control to accurately plan the part of the tissue to be removed from the corneal stromal layer under the flap, and then rinse it under the valve, and reset the corneal flap, so as to change the shape of the anterior surface of the cornea, adjust the refractive power of the cornea, so that the external light can accurately converge and image in the fundus, so as to achieve the purpose of correcting myopia.

There are two main types of surgery: one is laser correction and the other is true lens insertion.

All surgical methods are safe just to check that they meet the requirements of the surgery. It has nothing to do with the amount of money guaranteed.

It mainly depends on the degree of your myopia and the condition of your eyes. 、

In all surgeries, there is no bleeding during the procedure. You can rest assured that there will be eye drops for anesthetic during surgery. It doesn't hurt during the process.

After the operation, you can look at the computer and mobile phone normally, and pay attention to the time you use your eyes at the beginning. Don't look at it for too long at a time.

The human body is a whole, the human body is a living body, as a whole it is a relative equilibrium, and each part is also a phase.

to the equilibrium state. The laser ** eye is a local interference, destroying his original equilibrium state to establish a new equilibrium, there is temporary.

Efficacy, if the patient's body itself happens to be in the process of shifting from yin deficiency to yang deficiency, then his efficacy can be long-lasting. And if you suffer.

The person has been in a state of yin deficiency, and even the situation of yin deficiency is becoming more and more serious, so his ** has the characteristics of timeliness. It's like an old man going under the knife.

If you want to make children's eyes not myopic or myopia a little lower, the best way is to let the children's own qi and blood rise. Let the child.

In the process of growth and development, the children have enough nutrition and enough blood, which is the best method, and this is the national policy we should have.

Because this link is grasped, many of the problems behind it are gone, look at how many young people are crying for help on our Internet, and how many young people are struggling if they don't appear online. At present, the incidence of myopia in our country is more than 30%, and among middle school students, the incidence is more than half, and it is large.

The incidence rate among students is as high as 74%! In response to this problem, there is a **myopic method: lasik.

Lasik laser surgery has been the first case of LASIK hand since 1997, as the most popular method for myopia recently.

To date, millions of patients across China have performed this surgery. LASIK can be made in a short time.

Patients have improved their vision, which has attracted thousands of people who are desperate to remove their glasses. However, among these people, absolutely.

Most of them are people who don't know anything about this procedure, and why are there still so many in the eye centers of many hospitals.

Doctor with glasses? 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 world of this century!

Do you have glasses? As soon as you put it on, it definitely becomes true myopia. ,You can try the ** clear pupil and bright eye tea set,The effect is good,Don't let the fake become true,Otherwise, you can only operate.,I'm fine.,I didn't pay attention to it before.,Later, I had to be a soldier to use it quickly.,Fortunately, it's back to normal vision now.,Otherwise, I don't know how much it will cost.。

Myopia eye surgery can be done twice, but it needs to be closely examined. It mainly thins the cornea, which is equivalent to carving a lens on the most surface of the eye, and the cornea is thinned to a certain extent, and the effect of resisting external and internal pressure will be reduced, and unnecessary complications will occur. Therefore, as long as the thickness and surface morphology of the cornea allows, it can be done twice.

Whether you can do myopia laser surgery preoperative examination is an important step, if you are myopic again after doing it, you can make up the laser again, but whether you can do surgery, you still need to have a preoperative examination, you can do it if you meet the conditions, and it is recommended to choose other correction methods if you don't meet the conditions.

Surgery on the eye can only be done once.

Is it possible that I already have a slight keratoconus === If the corneal thickness is after 430, it is not a big problem.

ReLEx is suitable for patients with myopia between 500-1000, astigmatism less than 150, and corneal thickness sufficient.

Femtosecond lasers have a wider range of indications and more precise surgery.

The femtosecond laser produces a very accurate corneal flap thickness, which is 3 times more accurate than the lamellar knife, but the actual corneal flap merger occurs.

The probability of developing a symptom is tens of thousands of times lower. In addition, the negative pressure of the suction ring used to make the corneal flap with femtosecond laser is significantly lower than that of the corneal flap made with mechanical lamellar knife. Therefore, a femtosecond laser is used to make the cornea.

Flap, which can greatly improve the surgical safety of excimer laser ** myopia, especially for patients with thin cornea, large variation in corneal curvature, and high myopia.

Femtosecond laser surgery uses a laser to create a corneal flap without the need for a blade, and it can produce a corneal flap with a very precise thickness and a smoother surface, and there is almost no displacement, displacement, or fragmentation of the corneal flap. As a result, glare and ghosting can be reduced after surgery. However, in addition to the corneal flap, the occurrence of glare and ghosting after surgery is also related to the smoothness of the corneal cutting surface of the excimer laser, the size of the high-order wavefront aberration after surgery, and the size of the pupil.

Relate. There is also the possibility of glare and ghosting after femtosecond laser surgery, and there is less glare after surgery because the corneal flap is smoother.

The surgery is an all-laser LASIK procedure that uses a femtosecond laser to perform a corneal flap. Since it does not require a mechanical blade to make a flap, femtosecond laser LASIK surgery can eliminate almost all serious complications caused by corneal flap making. Based on the results of nearly 300,000 femtosecond LASIK surgeries that have been performed so far, no serious complications related to the surgery have been identified.

Surgery is predictable, and after preoperative testing, if the doctor believes that the results of the surgery are not satisfactory, or there are potential post-operative safety risks, or there are obvious risks after the surgery, then the doctor will not perform the surgery for you. If you can pass the preoperative examination and the doctor confirms that you can undergo the surgery, then the surgery is safe for you.

Hello, at present, the more common surgical method is femtosecond laser flap, excimer laser power, you said that the whole femtosecond is the entire surgical process using femtosecond laser, but this surgical method has certain drawbacks, not suitable for high myopia and astigmatism, and can not implement individualized surgery, it is recommended that you go to a professional eye hospital for a comprehensive preoperative examination, the advantage of this surgery is that there is a certain degree of predictability, if the detection of potential danger is not suitable for surgery, At present, the most advanced inspection equipment is the anterior segment panorama analyzer, you can check it first, I hope it can help you.

Advantages: Quickly solve the problem of myopia.

Disadvantages: high consumption, sequelae of surgery.

Laser surgery may cause eye diseases to be refused by famous doctors.

Today, laser myopia surgery is very common in Taiwan, but Tsai Rui-fang, an adjunct professor of ophthalmology at Taipei Medical University, who was the first to introduce the procedure in Taiwan, has announced that it will not be performed in the future.

Cai Ruifang emphasized that although LASIK has the advantages of accurate laser knife cutting, accurate myopia correction and no scarring reaction of the cornea, there are also complications such as glare, night vision loss and dry eye syndrome after surgery, according to the experience of tracking for up to 20 years, it is known that after the corneal flap of myopia patients is cut, it will not heal again, and can even be opened at any time, which is a fait accompli.

It is a good technique, but the disadvantage is that the power of the ** is limited. Personally, I am nearsighted, and I can almost recover after laser surgery, which also makes life more convenient, so I am certainly willing to do it.

Myopia laser surgery is a type of laser surgery to correct myopia, which includes laser optical keratomectomy (PRK), excimer laser in situ keratomileusis (LASIK, referred to as IK), excimer laser subepithelial keratomileusis (LASEK, referred to as EK), wavefront aberration-guided excimer laser surgery (TK), femtosecond, Six stages of femtosecond laser development.

The use of laser surgery**Myopia can effectively restore the patient's vision, but it requires a detailed examination of the patient's fundus to see if there are any other symptoms before the surgery. If there is an abnormality in the fundus, surgery should not be performed. In addition, a series of postoperative complications such as postoperative infection and dry eye syndrome may occur after surgery, and it is necessary to proceed as soon as possible**.

Xingtai Aier belongs to the old brand.

Laser surgery**Myopia is already very mature.

Myopia laser surgery has a history of twenty or thirty years and is a relatively mature method, which includes femtosecond laser, semi-femtosecond laser, excimer laser, etc. Different types of myopia laser surgery have different recovery times and different costs. The specific ** plan to adopt requires a detailed assessment of the myopia situation before deciding.

There are more and more myopic people around us, myopia brings inconvenience to many people's lives, and some occupations may not be suitable for wearing glasses, so it is necessary to solve the problem of myopia. At present, myopia laser surgery has a history of twenty or thirty years, and it should be said that it is a relatively mature method, including femtosecond laser, semi-femtosecond laser, excimer laser and so on. After different myopia laser hands, the speed of recovery is different, and the cost is also different.

Which kind of plan to take, you must go to a professional eye hospital for examination. Conduct a detailed assessment of the eye, including corneal thickness, power, fundus, etc., and then decide which way. Otherwise, there is a risk of serious damage to vision in the future, so this preoperative examination and evaluation is very important.

Especially for pregnant women, laser surgery should only be considered one year after weaning.

Can I use a laser for myopia**.

Pay attention to the posture of writing and work, avoid the phenomenon of being very close, and go to Shanghai Preh Eye Hospital. Health will be yours in the end! Generally, the distance between the eyes and the book is kept at 33 cm, the sitting posture should be correct, the back should be straight, and the discomfort should be avoided.
