When is laser surgery needed?

Hello, there are indications and contraindications for all surgeries.

Indications: 1. Power: 75 degrees to 2,000 degrees can be considered.

2. Age: There is no strict age limit, generally speaking, the best correction range: 18-50 years old, and the degree is stable.

3. Ocular conditions: no active ocular lesions and systemic diseases that affect the surgical effect, such as glaucoma, keratoconus, diabetes and other systemic diseases.

4. Have a reasonable expectation of postoperative results.

5. The diopter power is stable for more than two years, and the annual power change does not exceed 50 to 1. The comprehensive results of the preoperative examination were qualified.

Contraindications: Relative contraindications: There is related inflammation in the eye, there are related lesions in the fundus that require further **, mild dry eye syndrome, etc., if other data are qualified, there is no problem after the re-examination and it will not affect myopia surgery.

Absolute contraindications: There are keratoconus, glaucoma, insufficient corneal thickness, diabetes, collagen diseases, etc., these conditions are absolutely not suitable for this surgery.

Whether it is suitable for surgery needs to be determined through a comprehensive examination, and it is recommended that you can choose a professional ophthalmologist to do a comprehensive preoperative examination to determine whether it is suitable for surgery.

1. Age 18-55 years old, stable vision for more than two years;

myopia below 600 degrees, astigmatism below 600 degrees, hyperopia below 600 degrees;

3. The corneal thickness is greater than 450um above the best corrected visual acuity.

4. No active ocular lesions and systemic diseases that affect the effect of surgery, such as: glaucoma, keratoconus, diabetes and other systemic diseases, non-scar constitution.

5. All qualified preoperative examinations.

Despite systemic and ocular contraindications, the vast majority can be done, so the safest thing to do is to do a thorough examination before surgery.

Myopia eye surgery has strict surgical indication restrictions, which are as follows:

1. There is a requirement for the age of the patient, in the national consensus on surgical indications promulgated by the Chinese Medical Association, the age of the patient is required to be at least 18 years old and not more than 55 years old, and such a provision is for the patient to consider surgery when the vision is stable. However, if there are individual patients who have poor vision in one eye and serious imbalance in both eyes, surgery can be done at an early age, such as around the age of 17. Or some people can be 1-2 years old in advance due to the urgent demand for employment, but generally they can be advanced to 17 years old, and no matter how young they are, they can't do myopia eye surgery;

2. The patient's myopia degree is required to be stable, that is, the annual myopia degree growth does not exceed 50 degrees, and this stable state lasts for more than 2 years, before surgery can be considered;

3. Patients are required to have no immune system diseases in the whole body, such as rheumatoid arthritis, diabetes, etc. If there is a special condition in the eye, it is not possible to operate for the time being.

Therefore, patients should undergo strict examinations before surgery.

Myopia requires laser surgery. Myopia laser surgery is a type of laser surgery to correct myopia, which includes laser optical keratomectomy (Photo Refractive Keratectomy, PRK), excimer laser in situ keratomileusis (LASIK, referred to as IK), excimer laser subepithelial keratomileusis (LASEK, referred to as EK), etc.

According to your own needs, such as wanting to take off the glasses, such as taking the school entrance examination, taking the police academy examination, etc., you can surgically correct myopia.

Surgery is determined primarily based on the patient's eye condition.

Meet the following three points at the same time:

1. Be at least 18 years old.

2. The degree has been stable for at least 2 years.

3. After the preoperative examination of the regular hospital system, it is confirmed that it meets the requirements of laser surgery.

Laser surgery refers to the use of carbon dioxide light-emitting tubes to shoot high-power light on pathological tissues, which can cause inflammation to absorb and destroy tumors, and low-power can remove freckle and beautify**. There are excimer laser corneal resurfacing surgery, excimer laser in situ keratomileusis, and excimer laser subepithelial in situ keratomileusis.

Of course, it's glaucoma, some need laser surgery, and some are polyps and the like.

When is laser surgery needed? Well, if you have some way inside your nose to grow inside, you need to do laser surgery, auspicious tricks, give it out.

Laser surgery can be performed at the time of myopia**, but many people are reluctant to do it because it still has some sequelae.

There are some indications for laser surgery, such as laser vision correction surgery, which requires a certain degree of corneal thickness, and cannot be done if it is not achieved.

1.Myopia surgery requires a minimum age of 18 years and a stable refractive status for two years.

2.The cornea thickness is sufficient.

3.No active ocular disease and systemic disease that affects the outcome of surgery.

4.The degree of myopia is within the range that can be corrected by surgery.

5.Women who are pregnant or breastfeeding cannot have myopia surgery.

Because everyone's eye condition and fundus topography are different, some people's corneas are too thin to do... or for other reasons.

Hello, first of all, it has to thin the cornea in the ** area, for a patient whose cornea is already very thin, he is not suitable for corneal laser surgery, this is the most critical point for us to measure whether he can do surgery, there are some corneal diseases or some keratoconus, etc., these are not suitable for corneal laser surgery to correct myopia, specifically each patient may be different, you need to go to the hospital to do a detailed examination to know, there is a particularly serious dry eye syndrome, It is also not suitable for myopic eye surgery. ·

Myopia eye surgery requirement 1, age requirement. The general requirement is between 18 and 50 years old. Myopia patients over the age of 50 are often accompanied by eye diseases such as presbyopia. Teenagers have unstable spectacle prescription and immature eye development, so they are not suitable for myopia surgery.

2 degrees required. 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.

3. No eye diseases. Eye diseases, surgery, inflammation, etc. are not suitable for myopia surgery.

In most cases, myopia correction surgery is a selective surgery, and whether the surgery can be performed is not absolute, and each individual needs to be comprehensively measured according to its own situation, including age, occupation, habits, etc. Preoperative ophthalmic examination includes refraction, corneal thickness, corneal morphology, pupil size, intraocular pressure, fundus, etc. Based on the results of the examination, it is necessary to determine whether surgery is suitable and which type of surgery is suitable.

The degree of myopia that can be corrected by surgery is currently within 1200 degrees of myopia and 600 degrees of astigmatism that can be corrected by laser corneal refractive surgery. In addition, the corneal thickness is required to be appropriate, and corneal diseases such as keratoconus need to be excluded.

1. Generally over 18 years old. 2. The degree of myopia in the past two years is relatively stable, and the change does not exceed 100 degrees. 3. No serious systemic diseases, such as diabetes, immune diseases, etc.

4. Surgery is generally not recommended if there is active inflammation of the eye recently, including keratitis, iridocyclitis, etc. 5. The correction range of excimer laser surgery is generally within 1200 degrees of myopia, 600 degrees of astigmatism, and 1000 degrees of hyperopia. 6. The thickness of the cornea should be at least 450 microns.

It is best after the age of eighteen, after the myopia degree is stabilized, if it is not necessary for work, I recommend not doing it, it is okay to be young now, and there may be trouble when you are old, after all, it is a new technology that has been available in the last ten years, no one knows, what will be *** out in a few decades.

If you go, you can do it, and the hospital should find a better one, don't look for a small hospital, it's best to find a professional ophthalmology hospital.

Surgical Requirements for Myopia Surgery:

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.

There is no need to worry about the after-effects of surgery.

First, refractive surgery is a corneal surface surgery, which will not directly lead to lesions and sequelae of other eye tissues.

Second, a detailed preoperative examination will be done before the operation to ensure that the eye meets the surgical requirements, and the doctor will operate on the patient;

Third, as long as the doctor's instructions are strictly implemented throughout the operation, there will be no rumors on the Internet about myopia surgery causing cataracts, retinal detachment, blindness, eye inflammation and infection, etc.;

Fourth, if refractive surgery does lead to serious complications and sequelae, will the state allow the procedure to develop so quickly?

Clause. 5. The laser used in the surgery is to scan the cornea accurately without harming the internal tissues of the eyeball. Excimer lasers are cold lasers that precisely ablate the portion of the cornea that is expected to be removed without damaging the surrounding tissues and other tissues. The wavelength of the excimer laser is very short and only 193nm, so it cannot penetrate the eye at all, so there is no harm to the internal tissues of the eye***.

There is also no reason for the recurrence of sequelae after a few years.
