Can those tests that require vision be lasered? Are there any dangers associated with laser surgery?

I saw a post written by a doctor in the pastoral text**, sincerely advising those who are going to have laser surgery yet, if you don't want to become semi-blind or completely blind in the future, please don't go for surgery. It's more realistic, you can go and see it, refer to it. I showed my cousin, who was going to have surgery and was going abroad, and she gave up right away.

Anyway, this is a big deal, you can't be sloppy, you have to think twice.

Do you think about why so many doctors are still wearing glasses when they have such unique conditions, is it because they don't have the money to do surgery?

Nowadays, there are laser surgeries, but the cost is generally higher. Surgery is risky. It is recommended to go to large hospitals such as Beijing Tongren to inquire.

I read a report on TV, saying: The doctors in the hospital will not let their family members or acquaintances do such an operation, it is to operate on the eye, it is indeed careful consideration, otherwise it will be too late to regret it.

Look for some regular hospitals, don't go to some prefecture-level hospitals. After all, the eyes are your own, and if you don't cherish them, you'll regret them, and now there are more hospitals that claim that you can do such an operation. It is better to go to some provincial hospitals.

You don't have to go to Beijing, if you have a lot of money.

It's better to be careful, even if there is only a 1 in 10,000 chance of failure, if misfortune befalls you, nothing can save you.

Adults who are not allergic to the drug are fine.

The age must be over 20 years old, and the adult retinoid model will change if it is not finalized.

Allergies can be tested at the hospital.

1. At the age of 18, because the eyes of teenagers are still developing, and the eye axis is also growing, their refraction is unstable at this time, and the degree of myopia rises rapidly.

2. Must not suffer from the following diseases: ocular active lesions (keratoconus, infection, inflammation, etc.), severe hyperthyroidism, cataract, glaucoma, diabetes, etc.

3. People with scar constitution: People with this constitution not only heal slowly from wounds, but also slow to heal nerves. Therefore, after the cornea is cut, the cornea is more likely to form irregular or scarring healing, which affects vision and visual quality.

1.Be at least 18 years of age.

2.The curvature of the cornea is between 39-42 days.

3.There is no inflammation of the eye, such as conjunctivitis, keratitis, etc.

4.Glaucoma is not present.

5.There is no immunodeficiency or comorbidity with diabetes.

6.The corneal thickness is above 460 m.

7.The degree of myopia has been stable for more than two years, and there has been no sharp increase.

If you want to have laser surgery, you must meet the following three conditions, and your age is to meet the criteria of 18 years and above. The second is that the thickness of your cornea should meet the criteria for laser surgery. The third is that the myopia of your eyes this year cannot exceed 200 degrees compared to the myopia of your eyes last year.

Generally speaking, if you are at least 18 years old, the degree is below 1200, the degree of myopia has not increased in the past two years, the corneal thickness is more than 500 microns, and there are no other eye diseases, surgery can be considered.

Usually laser surgery**myopia is suitable for patients below 1000 degrees, laser surgery requires grinding corneal lenses, so the patient's cornea needs to have a certain thickness, so as to meet the surgical grinding lens space enough. If the patient has less than 1000 degrees of myopia but insufficient corneal thickness, improvement is usually needed.

First of all, it is necessary to distinguish between true myopia and pseudomyopia.

Pseudomyopia, which can be recovered in time**;

True myopia, under 18 years old, can control or reduce myopia in time; Those over the age of 18 can recover through surgery, but only if they meet the requirements of surgery and recover well after surgery.

Commonly used methods of myopia recovery:

1. Correct bad eye habits.

1. Avoid continuous operation of the computer and reading and learning for a long time, do not wait until you feel tired to rest, but should rest for 10-15 minutes every hour or so, or look at the green trees or vistas outside the window, or do eye exercises, so that the eyes are fully relaxed.

2. Maintain a good working posture when operating the computer and reading and studying. Maintaining an optimal posture with both eyes at eye level or slightly looking down at the phosphor screen will relax the neck muscles and minimize the area of the eyeballs exposed to air. Don't read while lying down, or in poorly lit areas, or on moving objects (such as vehicles).

It is advisable to use fluorescent lamps for reading books.

3. If the eyes are dry, red, burning or foreign body, the eyelids are heavy, the vision is blurry, and even the eyeballs are swollen or headache, you should immediately stop operating the computer and reading and studying, and rest for a period of time.

2. Adjust your diet.

Studies have found that increasing protein and decreasing carbohydrates** in the diet can reduce or stop the increase in myopia in adolescents with a genetic background who develop myopia. Therefore, to avoid the occurrence of myopia, eat less sweets and high-sugar foods. Too much sugar will produce a large amount of acidic substances in the blood, and the acid will combine with the salt in the body, especially calcium, resulting in a decrease in blood calcium, which will affect the toughness of the eye wall, make the eye axis easy to elongate, and promote the occurrence and development of myopia.

On the surface, people with myopia can supplement protein, calcium, phosphorus, carrots, bean sprouts, oranges, mandarins, red dates and other vegetables and fruits are also beneficial to myopia.

People with other medical conditions and people with imperfect myopia development cannot have myopia surgery, and it is recommended to consult a local regular hospital for detailed contraindications.

Laser surgery for myopia is a very routine surgery in ophthalmology and can be used to correct myopia. Not all people are suitable for laser surgery for myopia, such as the following conditions: 1. If there is active inflammation or serious systemic diseases of the eye, such as conjunctivitis, keratitis, stye, or accompanied by diabetes, systemic connective tissue diseases, immune deficiency, etc., surgery is not possible**; 2. If you are too young, such as under 18 years old, you can't have surgery**; 3. If the degree of myopia is too high, such as more than 1500 degrees, laser surgery cannot be done**; 4. If the thickness of the cornea is less than 460 microns, and the thickness of the corneal stromal layer is less than 280 microns, laser surgery cannot be performed in this case**.

Before myopia surgery, you need to do a preoperative examination, and after the examination, you will know whether the surgery can be done.

Contraindications of laser myopia correction surgery: ocular parameters do not meet the surgical requirements; Active** stained or inflammatory lesions in the eye; eyelid abnormalities such as incomplete eyelid closure, small palpebral fissures, severe entropion trichiasis; severe dry eyes; keratoconus; Patients with psychiatric abnormalities or diseases with systemic conditions that affect wound healing.

If laser surgery is not possible, you can consider MCT technology. The same effect can be achieved during the day. You don't need to wear any glasses.

People under the age of eighteen cannot have laser myopia surgery.

The following four groups of people are not suitable for this type of surgery:

Category I: keratoconus, glaucoma, rabbit eye, severe dry eye and ocular active inflammation;

The second category: severe amblyopia with very poor corrected vision;

Category III: systemic diseases that affect wound healing, such as diabetes, autoimmune diseases, etc.;

Category 4: Mental and psychological abnormalities.

Keratoconus, corneal ectasia disease.

Autoimmune diseases: These people are prone to corneal lysis and corneal removal is not recommended.

Systemic diseases or partial metabolic diseases, such as severe hyperthyroidism or hyperthyroidism, the cornea is severely exposed, and surgery is likely to increase the possibility of corneal lesions.

Active ocular lesions, such as intraocular infections, corneal infections, etc., are contraindicated during infection or inflammation.

Those who have poor fundus function, or who suffer from cataracts or glaucoma that seriously affect their vision.

The following 9 groups of people cannot undergo laser surgery for myopia:1inflammation and tumors in and around the eyes; 2. keratoconus; 3.

Glaucoma; 4.Systemic collagen diseases or autoimmune diseases, such as systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, diabetes, etc.; 5.moderate to severe eyelid insufficiency; 6.

chronic dacryocystitis; 7. Severe dry eye and corneal endothelial degeneration; 8.Pregnancy and lactation in women; 9. Mental and psychological abnormalities, with unrealistic expectations for surgery.

Some of these professional diseases must be diagnosed by a doctor's examination, especially the diseases of the eyes will be carefully screened during the preoperative examination; Some diseases require you to be honest and not hide your medical history because you want to have surgery. Power range: The ** range of laser surgery is myopia 100-1200 degrees, hyperopia below 600 degrees, and astigmatism below 600 degrees.

1.Severe corneal dystrophy, corneal degenerative diseases;

2.Patients with fundus lesions such as retinal detachment;

3.Patients with dry eye syndrome, keratoconus, glaucoma, diabetes, collagen diseases;

4.scarring constitution;

5.pregnant women and drivers driving at night;

6.Patients with severe amblyopia who wear glasses to correct extremely poor vision;

7.Those who have extremely high requirements for vision and have great concerns about surgery; Among them, patients with eye inflammation can still be operated after anti-inflammatory**.

At present, there are two main types of myopia surgery: one is corneal refractive surgery, which is what we usually call myopia laser surgery; **Four or five thousand to one or two hundred thousand, the other is lens refractive surgery, including lens posterior chamber intraocular lens implantation surgery (i.e., ICL implantation) and clear lens replacement surgery** is generally more than 30,000.

Only after the preoperative examination will you know which surgical options you can choose. Only what suits you is the best, not the more expensive the better.

Minors under the age of 18.

The degree of myopia continues to increase every year in adulthood.

keratoconus, glaucoma, rabbit eye, severe dry eye and active ocular inflammation;

The cornea is thin and has a high prescription.

Minor. The degree of myopia is unstable, and the cornea thickness is insufficient. There is inflammation of the eye, there is a lesion in the fundus. People with scar constitution, systemic immune system disease, and fear of myopia surgery.

Can myopia laser surgery be done for everyone?

First of all, it is not advisable to have surgery if you have eye diseases。Some patients suffer from active inflammatory lesions, such as acute conjunctivitis, keratitis, dacryocystitis, corneal ulcers, etc., and such patients are prone to infection during surgery, and many of them have uncomfortable symptoms after surgery. Surgery is also not recommended for people with dry eye, glaucoma, trachoma and retinal disease.

There are also some people who have scarring, diabetes, lupus erythematosus, etc., which can easily affect the degree of wound healing, and the effect of surgery is greatly reduced. Patients with the above diseases may have complications such as retinal loss and keratoconus shortly after surgery if they are forced**, and their vision will be seriously damaged.

Secondly, patients with too high a prescription or too thin cornea should not undergo surgery。Most of the laser surgeries on the market today are corneal laser surgeries, which require the patient's corneal thickness to withstand the amount of myopia correction due to the operation on corneal tissue. The higher the patient's power, the less remaining corneal stroma.

If the patient's myopia is too high, or the cornea is too thin, the cornea cannot withstand the amount of myopia correction, and the risk of surgery will increase.

Finally, patients under the age of 18 should not undergo surgery。Generally speaking, adolescents under the age of 18 have not yet fully developed their eyes and corneas, and their refractive power is not stable enough, while most people have little change in eye development and myopia in adulthood, and it is obviously much safer to have surgery in adulthood. In addition, patients with severe amblyopia are not suitable for surgery.

The development of medicine has brought us a lot of convenience, but it cannot be the only lifesaver for everyone. Paying attention to eye hygiene and ensuring good eye habits is the right way.

Invasion and deletion).

There are currently two main categories of myopia eye surgery: one is corneal laser refractive surgery, and the other is endoscopic surgery. No matter which of these two types of surgery, the most basic requirement for the patient to do the surgery is to be over 18 years old, if the age is too young, the patient's prescription has not yet developed steadily, and the prescription may face regression after completion, and it is also necessary to wear glasses, so the age is basically considered to be over 18 years old.

The refractive state of the patient is required to be stable in the past two years, that is, after going to regular dilated refraction within two years, the prescription has not increased significantly, it is basically stable, and it can be considered for surgery if the prescription is still growing, about 50 degrees, and the vision may regress after the operation, and you need to wear glasses again.

Hello, there are indications and contraindications for all surgeries.

Indications: 1. Degree: 75 degrees to more than 3,000 degrees can be considered.

2. Age: There is no strict age limit, generally speaking, the best correction range: 18-55 years old, but there are some special circumstances, minors have also been done, including over 60 years old.

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 degrees. 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. Hope it helps.
