Is it good to do laser for moderate myopia in the eye 20

Hello, now there are many kinds of surgery, the most advanced is femtosecond, you can understand it relatively, in addition, everyone's cornea has a certain safety thickness, so I recommend that most people do it before 600 degrees, except for some corneal congenital thinner, of course, since this laser correction surgery is called surgery, there must be certain risks and complications, the degree is related to hospital equipment, surgical personnel, disposable cutter head is not recycled and preoperative examination and analysis, Our common complications are dry eye, irregular astigmatism after surgery, etc. It is recommended that if you need surgery, you should go to a regular large hospital, and do not covet some small bargains for the sake of your eyes.

Generally speaking, if you are between 18-50 years old, your myopia is between 100-1200 degrees, your farsightedness is within 600 degrees, your astigmatism is within 600 degrees, your myopia has been relatively stable in the past two years, and there are no other eye diseases (keratoconus, glaucoma, retinopathy, immune system diseases), you are suitable for this kind of surgery, and you still need to go to the hospital for detailed preoperative examination.

No one can say what hospital it is.

Myopia is caused by the anteroposterior diameter of the eyeball being too long or the anterior surface of the eyeball being too convex for external light to converge accurately on the fundus. The laser is used to cut on the corneal stromal layer, so that the curvature of the corneal surface is reduced, the refractive rate is reduced, and the focus is shifted back to the retina, so as to achieve the purpose of myopia.

Excimer laser is an invisible ultraviolet beam produced by the excitation of fluorine argon gas after mixing, which is a cold laser that can accurately ablate the part of the cornea that is expected to be removed without damaging the surrounding tissues and other tissues and organs. In addition, the excimer laser has a very short wavelength of 193 nm and cannot penetrate into the eye, so there is no bad condition for the internal tissues of the eye, and there is no reason for sequelae to appear after several years.

After surgery, your vision can be restored to your current best-corrected visual acuity. In layman's terms, it is the best vision after wearing glasses.

This surgery is possible, and after you come to our hospital for an examination, the doctor will be able to use the results of the examination to determine your postoperative vision.

The principle of laser:

It is to cut the cornea with a laser, which is equivalent to turning the flat cornea into a concave lens. It's like wearing glasses.

Because the cornea itself is very thin, there is a certain danger that it will explode after cutting, so if that is the case, you should line up and go there.

Wait for the dead man's cornea to be replaced). This operation has been stopped abroad!

Myopia lasers.

It is very harmful to the eyes, and now the technology of non-surgical ** myopia has been born, and there is time to experience it when you have time, and the experience is completely impossible.

Requirements for Myopia Surgery:

1. Age requirements.

The general requirement is between 18 and 50 years old. Myopia people over the age of 50 are often accompanied by eye diseases such as presbyopia. In adolescents under the age of 18, the prescription of glasses is unstable and the eyeball is immature, and the myopia at this stage is adjustable, which means that the myopia can be reduced by taking medication.

The common use of Joy Eye Vision Nutrients is taken with warm water and insisted on taking it for a period of time, and the myopia degree will gradually decrease. Therefore, both are not suitable for myopia surgery.

2. Degree requirements.

The annual growth should not exceed 50 degrees, and the degree should reach more than 100 degrees and not exceed 1500 degrees; The astigmatism should be below 600 degrees, and the farsightedness should not exceed 600 degrees. The degree must be stable for more than two years. In other words, surgery can only be performed after the age of 20.

3. No eye diseases.

Eye diseases, surgery, inflammation, etc. are not suitable for myopia surgery.

4. Physical health.

People like diabetes that affect the recovery and healing of the stratum cornea are not suitable for them.

5. Other requirements.

It is not suitable for pregnant women, lactating women, people with severe amblyopia, mental illness and taking medication.

In addition to meeting the above mandatory requirements, more than 20 preoperative eye examinations are also required, each of which must meet the standard.

The requirements for corneal thickness are strict, and corneal thickness greater than 450um can be done.

Therefore, for those considering myopia surgery, these points must be clear. Although myopia surgery has been developed for 20 years and the technology is very mature, there are risks associated with surgery, so it is still necessary to be cautious, and most doctors do not recommend surgery.

Within 1000 degrees, it is within the scope of laser myopia correction surgery, depending on the results of preoperative examination.

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.

Age 18-55 years old.

Laser surgery is less than 1200 degrees of myopia and less than 600 degrees of astigmatism.

There are no eye diseases such as keratoconus, glaucoma, severe dry eye, etc.

The degree of myopia has not changed much in 2 years, and the degree is relatively stable.

I have enough desire to take off the camera.

Those who have passed a strict preoperative examination and are eligible for surgery.

100-1200 degrees of myopia, and at least 18 years old, myopia has been stable for more than two years, no inflammation of the eye, corneal thickness is sufficient, and there is an urgent desire to remove the lens can be corrected by laser surgery.

Generally, it is possible to have a myopia between 100 and 1200 degrees, but for safety reasons. It is important to consider not only the prescription, but also the age of the patient. Be sure to choose a regular hospital for processing**.

Nowadays, many myopic eyes will choose to use laser method for myopia in order to get rid of the trouble of glasses, and laser myopia is a more popular method in recent years.

Hello, there is no way to say whether surgery can be done just by looking at the prescription, this requires a series of detailed examinations before surgery, such as corneal thickness, corneal endothelial count, fundus examination, intraocular pressure, etc., so as to determine whether it can be done or which surgical method is suitable for it. For example, if all other conditions are met

Change the shape of the anterior surface of the cornea, change the radius of corneal curvature, reduce the corneal refraction, and correct the refractive error. The main method is to cut the cornea with a laser, etc. The depth of corneal ablation varies depending on the degree of myopia.

In order to ensure the effect after surgery, the thickness of the residual cornea is also required. Using a very precise femtosecond laser to cut the cornea, a more precise mechanical knife was prepared. The corneal flap is then ablated with an excimer laser under the flap to flatten the corneal curvature.

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.

Generally, between 100-1200, laser surgery can be selected.

The conditions for myopia surgery need to have a certain degree of myopia, and it is not recommended that the degree of myopia is too high. The recommended refractive power for laser correction of myopia is below 900 degrees, and if it is above 900 degrees, lens implantation surgery can be considered. In addition, if corneal laser surgery is performed, it is also necessary to meet the needs of the corneal shape to be regular, and the thickness of the cornea is sufficient, so that the laser cornea can be cut enough to avoid serious complications due to the small amount left.

If the shape of the cornea is not ideal, the astigmatism caused by laser removal may be large, or there may be complications such as keratoconus. If the lens implantation surgery is performed, it is usually necessary to meet the depth of the anterior chamber and the count or number of endothelial cells to be sufficient, so as to ensure that there is a certain space after the lens is implanted and will not cause too much damage to the cornea.

If you feel that you can't see clearly, you can go to the hospital to see, myopia is not something that everyone can do, there is a strict preoperative examination, and now more than 50 degrees can be operated, mainly depending on whether you meet the conditions to do it, if you want to do it, it is recommended to go to the examination first (dong

nan), look at the condition of the eyes, and then think specifically.
