What are the conditions for myopia eye surgery?

Myopia surgery is suitable for patients who wish to remove their lenses, who are over 18 years old, and whose myopia and astigmatism have been stable (the annual change in power is within 50 degrees) in the past two years.

In addition, patients also need to undergo ophthalmic examination and evaluation to rule out acute inflammation of the eye, infection, severe dry eye syndrome, other eye diseases and some systemic diseases and other contraindications to myopia surgery to ensure good health.

For women, myopia surgery should be performed to avoid pregnancy and early lactation.

1. Ensure the health of the cornea

The most common is that the cornea is on the front of this black eye, and this lens is cut on top of it, and then it is cut into the form of this concave lens, so it is necessary to ensure that the cornea is healthy and translucent enough, and then you can do this surgery.

2. The cornea is thick enough and the internal fluid is normal

The cornea must be thick enough, otherwise if we cut it, if the thickness is not enough, there will be problems in the future, and it is also necessary to ensure that your internal fluid is normal, so that hepatitis will not appear after surgery.

The new standard states that "distance visual acuity of the naked eye should be at or above in either eye, and distance visual acuity should be at or above in both eyes" is the same. In addition, it is also stipulated that if the distance visual acuity of the uncorrected eye is lower than that of any eye, but at the same time the distance visual acuity of the uncorrected eye is not less than that of the corrected acuity. The diopter should not exceed the range of less than 450 degrees for myopia and less than 300 degrees for hyperopia), and for "astigmatism, the difference between the two axes should not be greater than; Anisotropia should not be greater than.

The requirements are consistent with the original callout.

Conditions for personnel with myopia eye surgery to enter the civil aviation pilot team:

At least 6 months after corneal refractive surgery, and at least 18 years of age at the time of corneal refractive surgery; The refractive power should not exceed the range of 450 degrees for myopia and 300 degrees for farsightedness before surgery, and there are no other related pathological changes; The procedure is a superficial or lamellar corneal refractive surgery using an excimer laser or femtosecond laser.

The unaided distance visual acuity of the operated eye should not be lower, the distance visual acuity of the unaided eye of both eyes should not be lower, and the refractive power should be stable; The thickness of the cornea in any one place should not be less than 460 m; normal binocular vision; No obvious postoperative complications or sequelae such as glare, dry eyes, foggy cloudiness; And it has the original and complete preoperative examination data and surgical records including surgical cutting parameters.

If you want to know more about vision standards, we recommend Guiyang Aier Eye Hospital. Guiyang Aier Eye Hospital takes "innovation-driven, scientific and technological Aier" as the guiding principle, and hopes to improve the level of ophthalmic medical technology in China by building a world-class and national ophthalmic medical center; At the same time, through the global layout, the comprehensive and coordinated development of medicine, teaching, research, production and investment will promote the progress of human ophthalmology and visual science, so that more patients can rebuild their brightness.

Myopia is mainly a blurred image on the retina after the light rays are refracted by the refractive system, and the myopia that occurs after the eye axis becomes longer is the most common refractive error. Good vision can be achieved through glasses or surgical correction, and the conditions for surgery** are as follows:

1. Age: It is recommended for patients over the age of 18 to undergo surgery**, because considering that the degree of myopia is relatively stable in adulthood. However, if the patient's prescription continues to grow as an adult, surgery is not a candidate for surgery.

2. Power: It is recommended that the patient's myopia increase be controlled within the range of no more than 50 degrees per year, and if the annual increase rate is 100 degrees, it is recommended to postpone the operation and consider it after the degree is stable.

3. Eye diseases: When patients go to the hospital for examination, they need to exclude glaucoma, cataract, abnormal corneal curvature, keratoconus, dry eye, keratitis, conjunctivitis, rainbow chilitis and other diseases.

4. Corneal thickness: The thickness of the patient's cornea should be measured before myopia eye surgery, and if the cornea is thin, it is not suitable for surgery. normal intraocular pressure; Fundus normal.

5. Patients with hyperthyroidism, major depression and systemic diseases are not recommended to undergo myopia surgery

Therefore, it is recommended that patients undergo a comprehensive eye examination before surgery in order to achieve the best surgical results.

Myopia eye surgery mainly includes laser and intraocular lens implantation, to do myopia eye surgery, to meet two conditions, the patient's age needs to meet 18 years old, and myopia has been stable for two years, secondly, the patient is also aware that there can be no other eye diseases, because the hole is rough, which will lead to the result of the operation, increase the risk of surgery, it is recommended that patients who want to do myopia eye surgery need to go to a regular eye hospital for examination, and consult a professional doctor to judge the examination results, and reduce the risk of surgery. According to the doctor's diagnosis, a reasonable ** plan is formulated.

The conditions for myopia surgery are generally as follows: 1. Teenagers under the age of 18 to 50 years old, whose eyes are not fully developed, and their refractive power is unstable, and their postoperative vision may recede, or even hyperopia;

2. The degree of myopia should be stable for more than two years;

3. Patients with keratoconus, corneal scarring, preamblyopia, retinal diseases and defects, as well as systemic diseases such as diabetes, collagen diseases, and autoimmunity are not suitable for Huixiangchai surgery.

Myopia Correction Recommendations:

1. Pay attention to the time of clearing your eyes with a round one.

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.

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, and acupuncture acupuncture points of the cavity fluid of the Chinese Medical Bureau, combined with the 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 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.

Patients with the following absolute contraindications cannot undergo laser myopia surgery: suspected conus or confirmed cornea, active inflammatory reaction and infection, corneal thickness does not meet the surgical requirements, severe dry eye, missing and deformed eyelids, uncontrolled glaucoma, cataract that seriously affects vision, systemic connective tissue diseases or immune diseases, anxiety and depression and other psychiatric diseases. If you have a full range of preoperative examinations in the ophthalmology department and do not have any of the above symptoms, then congratulations, you have been awarded the ticket for surgery.

1. Age limit: 18-50 years old, over 45 years old can be examined to determine whether the operation can be performed.

2. The degree is good and the base is stable: the degree of myopia is stable within two years.

3. Appropriate corneal thickness: the corneal thickness after surgery is not less than 450 microns.

4. No eye disease: no active eye disease in the eye, such as dry eye, proptosis and palpepharoplasty, glaucoma, monocular patients, eye inflammation, amblyopia, cataract, fundus lesions, etc.

5. No systemic surgical restrictive diseases: such as autoimmune diseases, diabetes sock collapse urine disease, etc.
