Eye Disadvantages of laser surgery for myopia

The cornea of the eye that has undergone laser is relatively fragile, so it is necessary to pay attention to minimize strenuous exercise and avoid jumping directly down from a high place. Eat less foods that tend to increase intraocular pressure (cola, fried, garlic, etc.).

Sequelae, I'm afraid of being a few decades later**!! 11

The disadvantages are difficult to say now, many people say that the ** is good, but we have a few doctors here who have done thousands of laser surgeries, and their children are all wearing glasses.

The eyes take a lifetime, and no one knows how many years or more this technology has been introduced.

In the case of myopia, true myopia can be corrected by wearing glasses, and surgery can also be considered**, and laser surgery is currently an option to correct vision. The advantage is that it can make the vision reach a normal level, can get rid of the burden of wearing glasses, avoid the discomfort caused by wearing glasses for a long time, and can achieve lifelong benefits after a basic operation, which can meet the requirements of special occupations, and also has a certain beauty effect. However, there are also certain drawbacks to the surgery of myopic eyes, because the cornea will be affected to a certain extent after the operation, which can easily lead to a decrease in night vision and obvious eye dryness, which may lead to a decrease in myopic vision while improving distance vision, and it is easy to have symptoms of blurred near objects, and a small number of patients may also have infectious keratitis, corneal epithelial damage, allergic reactions, etc.

There are three major harms of laser ** myopia: first, the cornea will become thinner and easy to rupture after trauma; Second, if the eye medicine is not strictly prescribed according to the doctor's instructions after surgery, corneal opacity will occur; Thirdly, 10 to 20 years after surgery, it is easy to develop symptoms of dry eyes.

Benefits of Myopia Surgery:

1. It can reduce the refraction of myopic eyes, with an average of -2 0--5 0d;

2. It can improve the naked eye vision;

3. One-time surgery can correct myopia and astigmatism at the same time.

4. There is basically no scar after surgery.

5. The operation is fast, simple, stable, safe, short recovery period, and has good performance.

Disadvantages of myopia surgery:

1. Postoperative undercorrection, regression, and vision loss should not be ignored.

2. Halo and night vision may occur after surgery.

3. Dry eyes.

4. Complicated by severe keratitis.

5. Corneal flap dehiscence caused by accidental collision after surgery.

Myopia surgery has been developed for 20 years, and the technology is quite mature, but because it is a surgery, it is risky, so it is still necessary to be cautious.

And myopia surgery must be clear: myopia surgery must be over 18 years old, myopia degree between 100-1500 degrees, stable vision for more than two years, no other eye diseases, after a detailed preoperative examination, can be carried out myopia surgery.

Generally, children under the age of 18, because they are in the period of vision development and have strong eye adjustment, myopia can be restored by taking drugs to reduce the degree of myopia. It is recommended to take Leyan Vision Nutrients, twice a day, one pack each time, take it with warm water, and insist on taking it for a period of time, the myopia degree will gradually decrease, and it will avoid the trouble of surgery in adulthood!

Pros and cons of myopia surgery. I analyzed it this way, first of all, we said that the advantage is that you don't have to wear glasses, so that life becomes convenient, and you don't need to wear glasses to be relatively beautiful, beautiful.

The second is the disadvantages, first of all, complications may occur during the operation, and the complications will have a certain impact on vision. Another disadvantage is that it costs a certain amount of money.

Whether it can be operated on, then it is necessary to go to the hospital for examination to be sure!

If you can't do it, then you need to wear the right glasses, and then you need to pay attention to:

1. Pay attention to the time you spend with your eyes.

Children's eye development is not perfect, the ability to work is low, every time you read or write for an hour, you should let the child go to outdoor activities, do games, look into the distance, or observe the flowers and trees, so that the tense eye muscles are relaxed, eliminate fatigue. In addition, it is necessary to make the child's life regular, have enough sleep, and let the eyes get enough rest.

2. Pay attention to the light of your eyes.

Do not allow your child to read or write in dark light or sunlight. If a 25-watt light bulb is used indoors at night, the distance between the book and the bulb should be within 1 meter. If you use a 60-watt bulb on a stool, the distance between the book and the bulb should be 1 2 meters.

Cloudy days, dusk halls, weak light in the moonlight, and strong light in the sun are not suitable for reading and writing. When watching TV, it is necessary to maintain a suitable distance, which should generally be 5 7 times the diagonal length of the phosphor screen. The time to watch TV should not exceed 2 hours at a time.

3. Pay attention to eye exercise.

Physical exercise can enhance blood circulation and metabolism, supply more nutrients to the eyes, and enhance the resistance of the eyes, which is an indirect exercise for the eyes. The direct exercise is eye exercises, which is based on the massage, massage, acupuncture and acupuncture acupuncture points of Chinese medicine, combined with jujube Kuanhui medical sports, which is a scientific method to protect eyesight. Parents should learn the basic knowledge of eye exercises, give specific guidance and often urge their children to do eye exercises, and persevere.

4. Pay attention to the spring cultivation of the eyes.

In order to protect children's eyes, children can eat more carrots, animal liver, lean meat, to supplement vitamin A, or regularly supplement the comprehensive nutrition of the eyes with Leyan vision nutrients, and at the same time, it is also necessary to appropriately consume millet, tofu, animal liver and other supplements of vitamin B2, so as to avoid night blindness, corneal malacia, red eyes, dry itching and other symptoms. Eating too much sugar will harm your child's eyesight, so your child's sugar intake should be controlled.

5. Pay attention to regular inspections.

The reason for the regular examination is that the structure of the child's eyeball, binocular visual function, and intelligence are still in the process of continuous development after birth, and the content of the examination is different at different ages. The usual age of ophthalmologic examination is generally 2-7 days after birth, 42 days after birth, 3 months, 6 months, and 1 year of age, and then once a year. In this way, the problem can be detected early and corrected early, instead of waiting until the vision has deteriorated and there is a vision problem before going for a check-up.

Excimer laser** myopia is not harmful.

1 Safety Excimer Laser**Myopia is currently one of the safest surgical methods in the world. This technology is American. Japan.

Developed countries such as Europe were the first to successfully research it. In 1993, with the approval of China's Ministry of Health, clinical trials were first carried out in major hospitals such as Beijing and Shanghai, and then promoted to the whole country. Actors (such as Deng Yaping, Zhao Wei) have chosen excimer surgery for their careers and beauty**Myopia, and my country's astronauts have also undergone excimer surgery.

If there is a safety hazard, the Ministry of Health will not allow it to exist and develop.

2 No sequelae The excimer laser is a cold laser with extreme accuracy and can engrave on hair. The surgery is performed to reshape the cornea within the scientifically set limits, and there is no thermal effect when the corneal tissue is cut, there is no damage to other tissues, and there are no lesions left on the eye, so there are no sequelae.

3 Normal eyes will not** The human cornea is like a convex lens, changing its refraction, you can change the focus point, so that the focus falls on the retina, the myopia problem is solved, the reshaped cornea will not return to its original appearance, and the thinned lens will not become thicker, so the possibility of myopia again is very small, and the normal eye will not be myopic again.

4 The effect is accurate and immediate The effect of excimer laser **myopia is possible**, as long as your corrected vision can be achieved, and the patient and the doctor work closely together, it can be achieved or better the next day after surgery, and it will remain unchanged for a long time.

5 .Doctor's Questions Excimer**Myopia is a very delicate surgery that requires a lot of experience and skill to operate on a millimeter-thick cornea.

So far, there have been no problems with what the people around me have done.

Myopia laser surgery, also known as corneal refractive surgery, is mainly used for the correction of refractive errors, which has been widely carried out in clinical practice, and the efficacy is relatively certain, which can effectively improve the corrected visual acuity and remove the glasses, which is the advantage of refractive surgery. The disadvantage is that this surgery is invasive, so it is bound to bring some common surgical complications, such as overcorrection and undercorrection, postoperative refractive regression, dry eye syndrome, optical aberration, subjective claims such as glare, corneal interlaminar debris, corneal neurotrophic epithelial lesions, progressive corneal ectasia, diffuse interlamellar keratitis, etc., but the probability of these complications is still relatively low compared with the necessity of surgery. Therefore, it should be carefully chosen before surgery.
