What is the range of prescriptions for myopia laser surgery?

Under normal circumstances, laser surgery can be done below 1200 degrees, because the principle of laser surgery is that the higher the degree of myopia, the thicker the cornea that needs to be cut, and the thickness of the center of the cornea in the general person is 500 microns, and the surgery should ensure that at least about 300 microns are retained.

1. The patient has the willingness to remove the glasses, is mentally healthy, and has reasonable expectations for the efficacy of the operation.

2. Age 18-50 years old (special circumstances can be appropriately relaxed, such as career selection requirements, high anisometropia, corneal diseases need laser**, etc.).

3. In the past 2 years, the diopter has been stable and increased every year.

4. Refractive power: within myopia, hyperopia + degree, and astigmatism (the specific surgical plan should be based on the patient's preoperative examination results).

1) Degree or less: laser corneal surgery;

2) Within the degree: ICL phakic intraocular lens implantation surgery (currently the only reversible myopia surgery method).

3) Degree or above: RLE crystal replacement, ICL+ laser correction surgery at the same time.

5. Those who have been excluded from contraindications to surgery by preoperative examination.

6. On the basis of full understanding before surgery, the patient and/or family members need to sign the informed consent form.

Myopia laser correction can be done if the myopia is less than 1200 degrees, the astigmatism is less than 600 degrees, the corneal thickness is not less than 480mm, and the myopia growth is within 50 degrees in two years.

Excimer laser ** myopia is now a very mature technology, with high safety, short operation time, high stability and other characteristics, but there are indications for surgery. It is recommended to go to the local eye hospital for examination to see if it meets the surgical indications, and any surgery is risky, so it is also necessary to understand the complications of surgery.

This is not necessarily, but myopia surgery also has certain visual acuity and other requirements, and it must be met before the surgery can be performed.

1. Must be over 18 years old.

Myopia under the age of 18 is still in the stage of vision development. Myopia can be treated with medication**. It is generally recommended to take two packs of Joy Vision Nutrients a day, and insist on taking it for a period of time, the degree of myopia will be reduced, the vision will be improved, and there is no need for adult surgery.

2. The degree of myopia is between 100-1500 degrees, the degree of astigmatism is within 400 degrees, and the vision is stable for more than two years.

3. There are no other ophthalmic diseases, which do not affect the postoperative recovery.

4. The thickness of the cornea is thick enough.

After preoperative examination, only those who meet the requirements of surgery can be operated.

Indications for laser myopia surgery:

1. Myopia has the requirement to remove glasses or correct myopia;

2. Those who must be 18 years old and above;

3. The recent refractive state (myopia, farsightedness, astigmatism) is relatively stable, and the annual fluctuation range is within 50 degrees;

4. Patients with refractive errors with incomparable diopters in both eyes;

5. For those who wear contact lenses, stop wearing them for one week before surgery and stop wearing them for 2 to 3 weeks before surgery; 6. Patients with no active eye disease through eye examination;

7. The thickness of the cornea is greater than 450 m (degree, curvature);

Contraindications to laser myopia surgery:

1. Patients under the age of 18 (except for special circumstances), or those over 45 years old;

2. The diopter power has been unstable in the past two years, and the annual power progress is greater than 100 degrees;

3. The corneal thickness is less than 450 m;

4. Patients with acute keratoconjunctivitis, corneal ulcer and other active inflammatory lesions in the eye;

5. Those with eye diseases such as keratoconus, glaucoma, rabbit eye, severe dry eye and severe fundus lesions;

6. Patients with systemic diseases such as scar constitution, diabetes, collagen disease, etc.;

7. Pregnant women; 8. Patients with severe amblyopia with very poor corrected vision;

9. Those who have very high requirements for vision and have great concerns about surgery;

10. Those who have mental illness and are taking medication.

Myopia laser surgery can be done as long as it is below 1200 degrees, and the most commonly used in China are full femtosecond and half femtosecond surgery. [10s to test which correction plan is suitable for me].

There is a slight difference in nature between femtosecond and femtosecond surgery, in that femtosecond laser surgery uses a femtosecond laser throughout the entire process and does not switch with other laser modes. The key to ReLEx laser surgery is not to cut the corneal flap and then perform laser cutting, but to directly cut the upper and lower layers of the corneal stroma twice, and then make a small incision in the cornea through a special instrument to remove the lens. The femtosecond laser surgery combines the characteristics of femtosecond laser and excimer laser, first using femtosecond laser to make a flap on the cornea, and then switching to the mode of excimer laser after making the flap, and then the excimer laser completes the subsequent corneal stromal cutting work.

If you receive a relatively large impact, the femtosecond surgery may lead to corneal flap ectopy and corneal flap folds, while the femtosecond is relatively safer because the incision is very small.

If you want to know more about myopia laser surgery, we recommend consulting Beijing Mingshi Ophthalmology. As one of the largest professional eye hospitals in China, Beijing Mingshi Ophthalmology Hospital is constantly improving itself in all aspects, so that all people, whether rich or poor, can enjoy the right to eye health. With strict and delicate preoperative examination, authoritative surgical experts, scientific surgical procedures, and intimate postoperative care, it has won unanimous praise from patients and has a trustworthy reputation.

Laser myopia surgery power requirements: myopia is myopia, laser myopia eye power requirements are 100-1200 degrees, laser surgery belongs to corneal refractive surgery, there are requirements for the thickness of the cornea, if the corneal thickness is relatively large, through surgery ** myopia degree is relatively high. [10s to test which correction plan is suitable for me].

Generally, corneal lamellar surgery requires that the degree of myopia should not exceed 1200 degrees, and after the operation, the thickness of the corneal ** stromal layer should be at least 250 m or more, and it is generally recommended that 280 m is the safest. If the corneal thickness is not up to standard, it does not meet the surgical standards, and it is not recommended to do laser myopia. For patients with thin corneas, the prescription is relatively high, and other surgical methods can be considered to ** myopia, such as correcting myopia through intraocular lens implantation.

Through intraocular lens implantation to myopia, it is generally possible to have myopia of 2000 degrees and 3000 degrees, and astigmatism can also reach 500 degrees, so for patients with laser myopia, the cornea and myopia are mainly screened.

If you want to know more about the prescription requirements for laser myopia surgery, it is recommended to consult Beijing Mingshi Ophthalmology. Founded in 2011, Beijing Mingshi Eye Hospital has been focusing on the professional medical field of myopia for 11 years, providing all-round and personalized myopia solutions for myopia people of different ages and different needs.

The most commonly used methods are:

1. Get enough rest.

Don't be tired of using your eyes, use your eyes at close range for 40 minutes in a row, pay attention to looking into the distance and rest for at least 10 minutes; Combine work and rest to ensure adequate sleep!

Second, the "posture" should be right.

Don't use your eyes up close in too strong or too dark light! Don't lie down and read! Don't read in a non-static state! Such as sitting in a rickety car, walking.

Fourth, it is necessary to be "nutritious".

Pay attention to dietary nutrition, often eat Leyan vision nutrients, supplement the lutein, anthocyanins and zeaxanthin that the eyes have been consuming, and eat less sweets and fatty foods!

Fourth, it is necessary to check on time.

For adolescents with myopia, take the child to the hospital every six months for professional dilated eye refraction and long-term follow-up.

If it is pseudomyopia, it will gradually recover, and if it is true myopia, it will gradually control or improve the vision.

Myopia eye surgery costs about 6,000 yuan to 15,000 yuan, and the specific cost has a lot to do with the choice of surgery. When doing surgery, you need to choose a regular large hospital, there are experienced doctors to operate, myopia eye surgery is not very certain, the general myopia eye choice laser correction surgery, laser correction surgery is about 5000 yuan per eye. However, the charging standard of each hospital is different, so it is not uniform.

Myopia is generally caused by excessive use of eyes or reading and writing under unclear lights, or long-term desk work, or long-term stay up late and tired, which can cause myopia. For general myopia, you can choose to wear glasses**, glasses are more common, and it is also a more commonly used method of myopia. If it is high myopia, it is recommended to have surgery, which is the most effective and fastest correction method for high myopia, which is currently more popular and has a better effect.

With the development of science and technology, general myopia surgery can correct more than 1,000 degrees.

The myopia range is 100 degrees, and 1200 degrees can be used for myopia surgery.

Myopia eye surgery, generally referred to as excimer laser**Myopia surgery, the so-called excimer laser, refers to the laser produced by stimulated dimer. After nearly two decades of development, myopia eye surgery has reached a very high level, and tens of millions of myopic patients around the world have their glasses removed through excimer laser surgery.

The recovery after surgery is fast, no hospitalization is required, and the effect is especially obvious for patients with high and ultra-high altitude. It can correct vision, farsightedness and astigmatism on a large scale, without removing or destroying corneal tissue, without surgical sutures, and excellent visual quality can be predicted in advance.

Myopia surgery can be done above 200 degrees and below 1200 degrees, so it is recommended to consult a doctor in a professional place. For myopia surgery, Guangzhou Yinghua Ophthalmology is recommended, and its services cover the whole field of ophthalmology, and patients can provide one-stop ophthalmology services from basic ophthalmology examination to glasses, from special examinations, specialist clinics to various ophthalmic surgeries and postoperative procedures. [Click to test whether I am suitable for myopia surgery].

Myopia surgery usually requires a myopia degree greater than 200 and less than 1200 degrees can be done, at this stage, the degree of myopia will not make the cornea of the eye too thin, through half a minute or full femtosecond laser surgery is conducive to the correction of refractive error and prevent the continuous aggravation of myopia. Even if the degree is more severe than 1200 degrees Celsius, the cornea is thin, and the patient is likely to have various complications such as dry eye syndrome or eye infection through laser surgery**, so try to choose glasses for correction. Usually do a good job of eye maintenance.
