Can myopia surgery cause blindness Laser myopia surgery Will failure cause permanent blindness in th

Myopia surgery is not blinding in principle, the retina will not be touched at all during the operation, and there is no problem of blindness, and blindness is generally caused by cataracts, glaucoma, etc., these diseases are difficult to avoid eye diseases in the aging process, not the sequelae of myopia surgery.

After myopia surgery, there will be some complications according to individual differences, such as common dry eyes, glare and other manifestations, and the eyes will be more sensitive, easy to shed tears, and even if the eyes are overused, they will become myopia. On the other hand, if you do not pay attention to hygiene, it will also cause inflammation and infection.

Myopia surgery only touches your cornea and does not affect the retina at the back, so there is no risk of blindness. Myopia surgery is to integrate "glasses" with the cornea, rather than fundamentally changing physiological myopia, without wearing myopia glasses or astigmatism lenses, and at the same time obtaining a clear vision.

ReLEx laser myopia surgery is currently the most advanced myopia laser surgery in the world, with a very high level of safety and no risk of blindness. Femtosecond laser myopia surgery is a minimally invasive surgery with a small incision, which is characterized by the fact that there is no need to make and open the corneal flap, and the 2mm surgical incision maintains the stability of corneal biomechanics to the greatest extent.

Are there any postoperative sequelae of myopia correction?

As far as the facts are concerned, the development of laser surgery in China is still relatively mature, and there will generally be no surgical failure due to operation and equipment during the operation. But if the operation fails, the results are self-evident – blindness is only one of the consequences, and there can be even more serious consequences;

We know that myopia is because the parallel light rays 5m away enter the eyeball, and the focus formed by the refraction of the refractive medium of the eye falls in front of the retina, and cannot form a clear image on the retina. Laser surgery, on the other hand, uses an excimer laser scalpel to change the surface of the cornea, thinning your cornea into the shape of a concave lens, which is equivalent to carving your glasses into your cornea.

It doesn't change the nature of myopia, it just takes you out of the trouble of glasses for a while – your cornea becomes your glasses; We know that the cornea has the effect of protecting the internal tissues of the eyeball, and its thickness determines its ability to resist pressure; There is fluid in the eyeball, and if there is fluid, there is pressure, and the cornea of normal thickness can easily resist this pressure, but can the thinned cornea do? What if I don't resist the explosion?

This is an intraocular lens with a diopter implanted directly into your eyeball, replacing the role of glasses; In principle, it is stronger than laser surgery, but it has high requirements for crystals, and it may not be suitable for everyone. It is also expensive, and post-maintenance is also a problem.

And the same does not change the essence of myopia, just wear your glasses inside your eyeballs to get rid of the troubles of glasses; In short, if you don't really have no choice, let's bring glasses to shoot, although it's a little ugly, but it's much safer and cheaper! Positive envy.

Recently, a senior ophthalmologist in Taiwan has announced that he will no longer perform laser surgery! If you are not very old, not more than 18 years old, the degree does not exceed 800 degrees, and the fundus is normal, it is recommended that you actively seek professional **true myopia institutions****, or you can come directly to our Shining Lifetime Vision ** Center to receive ** training.

Normal surgery is certainly not blind.

1May cause blindness.

High myopia, also known as "pathological fluid myopia", refers to refractive error with a myopia degree of more than 600, accompanied by axial lengthening, fundus retina and choroidal atrophy, etc., and degenerative lesions as the main characteristics.

High myopia alone does not lead to blindness, but high myopia often causes some serious complications, such as retinal detachment. As a result, once a retinal detachment occurs, vision can be severely reduced, which can lead to blindness if left unchecked.

2. The main cause of blindness caused by high myopia is complications, such as retinopathy, glaucoma, amblyopia, etc., which need to be prevented. In addition to paying attention to changes in vision, it is also necessary to pay attention to any other abnormalities that appear in the early stage of the eye, such as flashes of light, floaters, visual field defects, progressive or sudden decline in vision, as well as eye soreness, pain and night blindness, and other special eye examinations should be performed if necessary.

31. Pay attention to eye hygiene.

People with high myopia should not rub their eyes with their hands to avoid eye infections caused by bacteria on their hands and increase the risk of blindness.

2. Avoid eye fatigue.

Don't keep your eyes glued to a certain point, and don't spend more than 40 minutes reading a book, playing with a computer or mobile phone.

3. Do eye exercises often.

Doing eye exercises at least twice a day can relax the eye muscles and help protect your eyesight.

4. Eat food that protects your eyes.

Goji berries, chrysanthemums, carrots, cod liver oil, salmon, nuts, etc. all have a certain protective effect on the eyes, and people with high myopia can eat them often to prevent eye lesions and blindness.

5. No longer read in strong or low light.

Strong light can scare the eyes and cause great damage to the eyes; Reading in low light makes it easier for the eyes to get tired, and it is not conducive to protecting eyesight and preventing vision loss.

6. Look at more green plants.

Green plants are tender to help soothe the eyes and relieve eye fatigue, you can put a few pots of green plants on your desk and desk, and you can take a few more looks.

4 Can be recovered by surgery.

Doing eye care and burying aerobics, eating eye-protecting food, or moving the eyeballs can only prevent the continued decline of eyesight and do little help to restore vision. But it doesn't mean that high myopia can't be recovered, modern medicine has been able to help restore vision through laser ** high myopia.

However, this kind of laser ** myopia surgery is only suitable for high myopia below 2000 degrees, and the risk is relatively high if it is higher.

No, surgery will not lead to the risk of blindness, if you will be blind, who will do it, although myopia eye surgery has been used in clinical practice for more than 20 years, but myopia friends are most worried about "20 years after my myopia eye surgery, will there be eye problems after 30 years, and will the prescription be **?" "The so-called **, also known as regression, is related to the repair of post-traumatic hyperplasia of the cornea after surgery, and if it occurs, it generally occurs within 6 months after surgery. Therefore, the longer the time after surgery, the lower the chance, and even if it occurs, the degree of myopia is extremely limited and predictable, and generally does not affect your daily life and work.

If the myopia degree increases in the first few years after surgery, other reasons should be considered, such as myopia with unstable myopia before surgery, and the myopia degree may increase after surgery; Or the occurrence of very rare corneal ectasia or keratoconus, now large regular hospitals often add a new anterior segment analyzer (not a corneal topography), which can generally be screened during the preoperative examination, and you will not be recommended for surgery. Therefore, it is very important to use the anterior segment analyzer for preoperative examination, but many hospitals do not have this kind of equipment. Since the development of myopia eye surgery in the 90s, with the continuous update and development of examination and surgical instruments, the diversification of surgical methods, the safety and accuracy of surgery have been qualitatively leaped, and the vast majority of myopic friends have gotten rid of the trouble of glasses, obtained good vision, and improved the quality of life.

Hello, first of all, it is very certain that there is no possibility of blindness in surgery.

1. The surgery is done on the cornea, the outermost tissue of the eye, and does not involve the fundus of your inner retina, so there is no possibility of blindness.

2. This operation has been in China for 30 years, if there is really a blind situation, the country has already stopped this operation, after all, this is not a must-do**.

3. At present, the state allows some specific groups of people: to join the army, to enter military schools, astronauts, and pilots are doing this surgery, which is enough to prove the safety of the operation.

4. Now the well-known experts in professional eye hospitals have done this operation themselves or their own families, for example, Professor Li Ying of Beijing ****, Professor Wang Kai of Peking University People's Hospital, Professor Wang Qinmei of Wenzhou Medical College has operated on his son, etc., as professionals, they or their families are doing this, which is enough to prove the safety of the operation itself.

However, after all, this is the scope of eye surgery, as long as it is surgery, there will be indications, suitable for people, it is recommended that you find a professional eye hospital, good experts, good equipment, professional places to do examinations and surgeries, I hope it can help you.

Before myopia surgery, the patient needs to go through a comprehensive examination, the doctor fully understands the patient's eye data, excludes surgical contraindications, and formulates the optimal refractive surgery solution according to the myopia degree and eye conditions, so as to achieve the best visual effect. If you don't meet the surgical requirements, you can't have myopia surgery! So myopia surgery is safe!

Stop listening to online rumors!

There are many types of myopia eye surgery, including corneal refractive surgery, intraocular refractive surgery, etc., and the patient needs to do a detailed examination before the operation to see if the patient can adapt to myopia eye surgery. At present, myopia eye surgery is relatively mature and will not cause blindness. However, some patients with high myopia will have vision loss due to complications of myopia, but this is not caused by myopia eye surgery.

You won't be blind, you have to worry too much, and you will be told eye drops after the operation to reduce the postoperative symptoms and make your eyes look bright.

One of my neighbors has done it, and I heard that it is quite good, but in the long run, it is not very good, because I have heard that the eyesight will be worse in about ten years.

For myopia surgery, the risk will be relatively low, all surgeries will have certain risks, it is recommended that you choose a regular, qualified medical unit to minimize the possibility of complications.

Myopia surgery only operates on the cornea on the surface of the eye, and has no effect on the tissues and deep structures around the eye, that is, the retina is not touched at all, and the operation principle is not blinding.

Beans, red and green vegetables, potatoes, vitamins, and people with eye fatigue should pay attention to the balance of diet and nutrition, protein foods, eggs, fruits, etc. contain lutein, and usually eat more coarse grains.

Complications can occur with any surgery, and the problems that may arise after laser surgery are: dry eye manifestations; Postoperative opacity under the corneal flap that affects vision; Postoperative vision regression. However, complications can be avoided as long as regular medication and good eye habits are taken after surgery.

The possibility of myopia again is relatively small.

Hello, from a principle point of view, myopia laser surgery is only done on the surface of the eyeball, using a cold laser to act on the surface of the eyeball, the laser cannot penetrate the cornea during the operation, nor will it enter the eye to damage the eye structure and tissues, so there is no risk of blindness and blindness. As for some people who are still worried about whether blindness will occur in old age, in fact, it is the same reason, laser surgery ** myopia only improves vision, and does not damage the retina of the eye and cause blindness, blindness mainly occurs in diseases caused by retinal optic nerve damage, the operation does not touch the inner eye, nor does it change the structure of the eye. Therefore, from the principle of myopia laser surgery, there is no serious harm in myopia laser surgery, let alone blindness.

Myopia surgery will not lead to blindness, generally postoperative damage recovery within 1-2 weeks, complete recovery in 1-3 months, the former is generally within 1 week after surgery, the need to standardize the use of anti-infective drugs and anti-inflammatory drugs, 1-2 weeks after the wound recovery, pay attention to rest.

The latter should not overuse the eyes for 1 month, and it is best not to use the eyes intensively for 3 months to allow it to fully recover. Myopia surgery has stable vision for about half a year.

When considering myopia surgery, you need to know that you must be over 18 years old, with a myopia degree of less than 1500 degrees and no more than 400 degrees of astigmatism. If the vision is stable for more than two years and there are no other eye diseases, only those who meet the requirements can be operated on after a rigorous preoperative examination, and not all myopia can be operated.

Generally, those under the age of 18 are still in the stage of vision development, and the adjustment of the eyes is strong, and myopia can be taken with drugs**. Doctors generally recommend taking two packets of Vision Nutrients a day, for a period of time, the degree of myopia will gradually decrease, and the vision will be improved, which can avoid the trouble of surgery in adulthood.

Everyone's situation is different, so the individual is different from the difference, there is nothing in the small probability that the event does not happen, but once it happens, the consequences are 、、、

In some cases, faces are OK. Myopia refers to the fact that when the accommodative effect is completely relaxed, the parallel light rays from the infinity or the optotic target 5 meters away enter the eyeball and form a focal point in front of the retina through the refractive interstitium such as the cornea, aqueous humor, lens, and vitreous humor, resulting in unclear images.

Theoretically, as long as the cornea is not a big problem, the situation allows, and the laser can be redone. If your financial situation allows, I suggest that you can consider myopia surgery ICL, which is the best way for myopia at present, and it can be redone without affecting the cornea. You can go to the ophthalmology department of the local big hospital for consultation.
