How many degrees can I not have myopia surgery? If you are nearsighted, you can t do surgery

If the myopia exceeds 1,02 and the astigmatism exceeds 6, surgery cannot be performed. Moreover, the degree of myopia has been stable for more than two years, and the health is good, especially the eyes must be free of diseases, such as glaucoma, etc., but generally the higher the degree of myopia, the greater the risk. It is recommended to do a detailed examination before surgery to determine whether you are suitable for surgery.

The availability of myopia correction depends on the surgical method and fundus retinopathy. Myopia correction is divided into corneal surgery and intraocular lens surgery. Corneal surgery is below 800 degrees of myopia, and the corrected vision is better.

Lens implantation surgery is for patients who are above 1000 degrees and cannot have corneal surgery. Myopia correction cannot improve and prevent the pathological changes in the fundus caused by myopia.

Answer: If it is more than 600 degrees, you need to go to the hospital for examination, and the doctor will give you advice!

My advice, no matter what degree you have, don't do myopia surgery. Generally, there is a certain amount of risk.

I don't know, but it is said that femtosecond surgery can be done at more than 1000 degrees, and general laser surgery can be highly myopia.

You can go to the hospital for a check-up and see if there is a ** plan.

If you can do it without surgery, try not to have surgery.

This problem still needs to be checked by the hospital before it can be determined.

This thing varies from person to person.

I went to the hospital for a check-up, and let the doctor decide.

Myopia correction surgery is not available to every myopia patient, you need to look at the age, prescription, and congenital conditions of the eye such as corneal thickness, corneal topography, fundus condition, etc.

The age of surgery is limited to 18 to 55 years old, the degree of myopia is limited to 1200 degrees, the degree of astigmatism is within 600 degrees, and the growth of myopia in two years is within 50 degrees.

However, congenital conditions such as corneal thickness, corneal topography, fundus condition, etc., need to be checked and confirmed by a local professional ophthalmology hospital, and can only be examined by professional instruments.

As long as you pass the preoperative examination, you can have surgery with peace of mind, and it is recommended that you go to a local professional eye hospital for examination and consultation in time. lyh collar one and 06

If the patient's myopia is greater than 1000 degrees, for example, 1500 degrees, it may not be suitable for ReLEx surgery.

Because the ReLEx surgery is to form a lens in the cornea, and if this lens is taken out again, our cornea will become thinner, and this thinning has a certain safety range, and we cannot thin it infinitely. Just like the tires of a car or a balloon in us, if it is obviously thinner in one place, the place will bulge outward and bubble, so any of our ophthalmologists will make a safety assessment of the patient's eyes when doing surgery, that is, whether the patient's eyes are still safe after the operation, we will consider all his indicators, such as the shape of the cornea, the thickness of the cornea, and how much corneal thickness can he leave after the femtosecond laser. This must be within the security limits set by the state.

In general, myopia surgery is not recommended if myopia exceeds 1500 degrees.

**Surgeries for myopia include: excimer laser keratomectomy, excimer laser corneal in-situ in-situ incision, excimer laser sub-epithelial flap keratomileusis, and intraocular lens implantation, which is suitable for myopic patients with a refractive power of less than 1500 degrees and a relatively stable power within two years.

In addition, surgical myopia requires the thickness of the cornea and the density of corneal endothelial cells. Surgery cannot be used to correct the refraction when the corneal thickness is less than 450 m and the density of corneal endothelial cells is less than or more than 2899 410 mm². Patients with eye diseases and other underlying systemic diseases should not be surgically treated**.

It is recommended that myopia patients improve their eye examination and choose the appropriate way before undergoing the first procedure.

If the myopia is above 1000 degrees, surgery cannot be done. Due to high myopia, the cornea may be cut too much during surgery, which can induce secondary keratoconus, which may also increase the onset of intraocular inflammation or infection. Therefore, before this surgery, it is also necessary to have a corneal thickness test and a corneal topography examination, and it is also necessary to know the power of vision before choosing the right surgical method for you.

If you choose laser correction surgery, it is best to have a myopia degree of 200 to 1300. If the myopia of men is below 200 degrees, it is generally not recommended to undergo myopia eye surgery, and the vision can be improved by adjusting lifestyle habits. Myopia surgery is also not recommended if the male has myopia above 1200 degrees, or if it is accompanied by astigmatism symptoms above 600 degrees.

Before myopia eye surgery, men need to go to the hospital to have their vision checked and pay attention to eye hygiene three weeks before surgery. After surgery, men should develop good eye habits, avoid eye water for one month after surgery, and secondly, go to the hospital regularly for reexamination. In general, laser surgery for myopia is suitable for high myopia with a degree below 1000 degrees, if the power of the myopic eye is too high, the more corneal thickness will be cut by the laser, which is unsafe.

Laser surgery requires not only the patient's visual acuity, but also the fundus and whether there are other complications, etc., which requires a comprehensive examination to be comprehensively evaluated. There are also certain risks associated with myopia eye surgery, so be sure to choose a regular hospital.

We should say that if the thickness of the patient's footsteps is normal, it is generally about 1,000 degrees, and myopia can be corrected by laser surgery. But if it exceeds 1,000 degrees, a new surgical correction method may now be required. In general, with this new surgical correction method, it can be corrected even at about 2,000 degrees.

First of all, let's talk about laser myopia eye surgery. Because he wants to change the curvature of the cornea by cutting the corneal tissue, so as to correct myopia, we know that he can't grind his foot very thin in the whole eyeball. In this way, the eyeball cannot withstand a certain amount of pressure, and it is also easy to cause some complications such as keratoconus.

Therefore, we require a corneal thickness of at least 460 microns to perform laser surgery. And if it is more than 1,000 degrees, we do not perform this laser surgery. But we just talked about a new surgical method called phakic intraocular lens implantation, which is simply referred to as ICR surgery.

It is made by making a special intraocular lens for you to put in your eye, which is equivalent to putting glasses in your eye. If it is corneal refractive surgery, it is not suitable for more than 1500 degrees. The optimal range of corneal refractive surgery is 800-1500 degrees, and it is recommended that the thickness of the cornea should not be less than 400 microns after corneal cutting; If the cornea is too thin and the power is too high, ICL surgery may be an option**; If ICL surgery is not suitable, lens removal and intraocular lens implantation can be done, and myopia above 3000 degrees can be improved to a certain extent, and even the purpose of lens removal can be achieved.

Myopia surgery cannot be done if it is more than 1200 degrees. It is not recommended for high myopia, and surgery can be done if the patient is more than 600 degrees. In general, this criterion cannot be met, and strict screening is required in the outpatient clinic before surgery, and surgery cannot be performed if systemic immune diseases or other fundus lesions are found.

If the myopia is too high, the surgery cannot be operated, and the surgical requirements for implanting an intraocular lens are stricter, and if the anterior chamber is too shallow, the lens is too large, and the corneal endothelial cells are not functioning properly.

Myopia surgery can be performed if the degree of myopia is generally between 50 and 1000 degrees, astigmatism is below 600 degrees, and farsightedness is below 500 degrees. [10s to test which correction plan is suitable for me].

Precautions after myopia eye surgery:

1.For the first week, the patient should not get water into his eyes, so as to avoid bringing bacteria into his eyes and causing eye infections.

2.Don't rub your eyes. Patients will be instructed not to rub their eyes for a week after myopia surgery.

3.Instruct the patient to order eye drops carefully. Eye drops have many functions, such as preventing bacterial infection, preventing refractive regression, preventing dry eyes, and promoting wound recovery.

Therefore, the re-examination of myopia must attract the attention of patients.

If you want to know more about myopia surgery, we recommend consulting Beijing Ming Ophthalmology. Since its establishment 11 years ago, Beijing Mingshi Ophthalmology has always insisted on carrying out academic exchanges and promoting the common development of the industry. Since 2012, Mingshi Optometry has held two professional academic conferences every year, inviting domestic authoritative ophthalmology experts to give lectures on the spot, and exchanging clinical technology and research results with ophthalmologists from all over the country, which is professional and trustworthy.

For myopia eye surgery, patients with eyes over 2000 degrees can not be pure as surgery, for myopia eye surgery, you can follow the doctor's guidance through laser excision surgery or intraocular crystal implantation, which can improve the patient's myopia symptoms. For laser surgery, if the patient's eye is more than 1000 degrees, this surgical method is no longer used**, and a lens implant is required to improve the symptoms.

Myopia is caused by poor daily eating habits or genetic reasons, and patients should develop good eye habits in their daily life. Do enlightenment.

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, 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.

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 stool hunger exercise for the eyes. The direct exercise is eye exercises, which is based on the massage, massage, acupuncture and moxibustion acupuncture points of Chinese medicine, combined with the medical sports of jujube kuanhui, which is a scientific jujube kuanhui 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 eye nutrition.

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.

Regular check-ups are due to the fact that children's eye structure, 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.

If the eye is myopic to more than 1200 degrees, surgery cannot be performed.

The surgical object needs to meet certain conditions, all 18 to 55 years old, myopia with stable power in the past two years from 50 to 1200 degrees, astigmatism below 600 degrees, and farsightedness below 600 degrees, and there is a strong need for "de-mirroring", are suitable. In the end, the results of the preoperative examination will determine whether the operation will be performed.

Myopia laser surgery is a surgical method to accurately cut the cornea to achieve the purpose of correcting myopia. In fact, as long as the patient is confirmed to be suitable for surgery through professional preoperative examination, the expected results can generally be achieved after surgery. Moreover, if the patient's myopia is relatively low, the recovery after surgery will be relatively quick.
