Are there any age requirements for laser vision correction?

The conditions for laser surgery for myopia are as follows: 1. Be over 18 years old, and have a stable myopia degree for more than 2 years. 2. There are no surgical contraindications such as conjunctivitis, keratitis, and severe dry eye syndrome in the eye.

3. The thickness of the cornea should be thick enough. 4. Intraocular pressure is normal, and there is no manifestation of high intraocular pressure and glaucoma. 5. The lens is transparent, and there are no cataracts and other factors that affect vision.

6. The fundus is normal, and there is no severe degeneration of the surrounding retina, retinal tear or retinal detachment. If retinal degeneration and tears are found during preoperative examination, retinal photocoagulation** is required, followed by retinal photocoagulation** 2 weeks after surgery, and surgery can be considered if there is no abnormality**.

Excimer laser surgery. The excimer laser has a particularly strong ability to shape the cornea, very accurate, and the use of the excimer laser for corneal shaping is equivalent to grinding a lens on the cornea, so that the correction effect of this technology is particularly ideal, so the excimer laser has now become the main way for us to correct our vision. Excimer laser surgery is suitable for the following people: -50 years old 2. The degree of myopia is stable for more than two years 3. The corneal thickness is appropriate 4. There is no inflammation in the eye, such as acute conjunctiva, keratitis, etc. 5. Not in the active stage of diabetes, hyperthyroidism, etc. Good health 6. Myopia 100-1400 degrees, astigmatism below 600 degrees, hyperopia below 600 degrees, and hyperopia below 600 degrees.

Laser-corrected vision is basically not harmful to the eyes.

Laser surgery is just a "dermabrasion" of the cornea. There are two main parts of the eye that can change the angle of refraction of light, one is the lens and the other is the cornea. For myopia surgery, ophthalmologists can "start" these two parts.

The commonly used laser surgery at this stage is superficial surgery, which only makes a fuss on the cornea. The myopia lens is a concave lens, and the procedure is to grind the middle of the cornea, which is equivalent to making a lens on the cornea. ”

Comparing the eyeball to a basketball, surgery is equivalent to scraping the surface, and it has no effect on the ball. Since it is only a "superficial article" and does not touch the deeper tissues, it has no effect on fundus diseases, lens lesions, etc., and will not increase the incidence of these eye diseases.

However, vision recovery after surgery varies from person to person. Everyone is developmentally different, so each person's ultimate visual acuity (i.e., the best corrected visual acuity achievable) is different. "The ideal outcome of myopia surgery is to achieve the best corrected visual acuity before surgery.

If the preoperative corrected visual acuity cannot be achieved, then the postoperative visual acuity will not be able to reach this level. It's like running 100 meters, maybe I can't run 11 seconds in my life, no matter how much I train, it's all natural, so I have to have an accurate mental expectation of myself.

The probability of ** after surgery is less than 5%, and most people can say goodbye to myopia after surgery. Moreover, the current personalized surgery settings are very fine, if it is an industry with long-term eye use, the doctor will reserve a farsightedness reserve of about 75 degrees during the operation, which can also be avoided to the greatest extent.

However, it is still necessary to pay attention to eye hygiene and avoid eye fatigue after surgery, as excessive eye use for a long time may indeed lead to the recurrence of myopia.

Are you asking about myopia surgery? Those who are over 18 years old can do it.

Myopia surgery is generally suitable for patients between the ages of 18 and 50, and needs to meet a steady increase of no more than 50 degrees per year. Of course, the age group of 18 to 50 years old is also a relative concept. If the difference in the power of the child's two eyes is too large, such as 200 degrees in the left eye and 1000 degrees in the right eye, and the vision cannot be corrected by wearing glasses, in order to prevent amblyopia, myopia correction surgery can be done.

In addition, you need to consider the profession you are engaged in. If you are engaged in sports, dance, etc., the age can be extended to 60 years.

See how you get your vision corrected. If you use a smart vision correction device, it can be used by teenagers aged 6-18 years. If it's laser surgery, it's after the age of 18.

Hello! Excimer laser surgery is suitable for the following people:1

Age 18-55 years old, stable vision for more than two years; 2.myopia below 2000 degrees, astigmatism below 600 degrees, hyperopia below 1000 degrees; 3.Above the best corrected visual acuity, the corneal thickness is greater than 450um.

4.There are no active ocular lesions and systemic diseases that affect the surgical effect, such as: glaucoma, iritis, fundus hemorrhage, omentum detachment, keratoconus, diabetes, immune, collagen and other systemic diseases, non-scarring constitution.

Due to individual differences, the achievable postoperative visual acuity is different for each person, and it is generally possible to revert to your current best-corrected visual acuity, which is normal.

Hello! The best suitable population for excimer myopia surgery is:

Be over 18 years old (except for special circumstances, such as high farsightedness, too much anisometropia, etc.);

The refractive state in the past two years has been basically stable (the annual change does not exceed that;

The thickness of the cornea** should be greater than 450mm;

For those who wear contact lenses: soft lenses need to be stopped for more than 1 week, hard lenses need to be stopped for more than 3 weeks, and OK lenses need to be stopped for more than 3 months;

No organic lesions on ocular examination;

Mental and mental health, fully understand and be able to accept the problems that may occur during surgery.

In addition, not everyone can have myopia surgery, there is a strict examination before surgery, and myopia surgery can only be done after passing the examination.

Hello: The applicable population of excimer laser myopia surgery is 18-50 years old, myopia below 1200 degrees, farsightedness, astigmatism below 600 degrees. Generally, after the age of 18, there is no fluctuation of about 100 in vision within two years, and preoperative examination is basically possible.

However, myopia surgery is not suitable for everyone, and it is necessary to go through a very detailed comprehensive eye examination before surgery to determine whether it is suitable for surgery and which surgical method is suitable for it.

Laser myopia surgery** is performed between 18 and 50 years of age, with myopia ranging from 150 to 1450 degrees, hyperopia below 600 degrees, and astigmatism below 600 degrees. The corneal degree is greater than 450um, the examination has no surgical contraindications, no systemic immune diseases, non-scar constitution, the refractive state is relatively stable in the past two years, those who meet these conditions can basically do laser surgery, most of the myopia can be corrected after surgery, but it is still necessary to determine your vision after surgical correction by the thickness of your cornea, you can consult an expert after the preoperative examination, which can be estimated.

This is very much not recommended. Although this surgery has been developed in Japan for a long time, it is still a cutting-edge surgery in a medically advanced country like Japan, and few people do this surgery. Because in the ophthalmology community, this surgery is still very controversial.

The human cornea is originally a spherical shape that evenly withstands pressure from the anterior chamber. The principle of laser correction of myopia is to cut the central part of the cornea, so that the cornea, which has a uniform thickness, becomes a concave lens, thus replacing glasses.

With age or other factors, the intraocular pressure rises or external shocks can cause the cornea to become deformed. As the ability to withstand pressure decreases, the thinned part of the middle protrudes, resulting in a keratoconus. More severe cases can lead to severe vision loss and necessa transplantation.

So, wear glasses if you can, and don't risk your future vision for the sake of beauty.

Myopia surgery is suitable for age: 18-55 years old, with stable vision for more than two years;

Correction range: myopia below 2000 degrees, astigmatism below 600 degrees, hyperopia below 1000 degrees;

You can do it when you are at least 18 years old, and the higher the normal degree, the better the effect. Normal will return to left and right.

You can do it at the age of 21, don't believe the statement that you can do it at the age of 18.

18-55 years old, as for how much correction, depending on the specific situation, can generally achieve the best visual acuity corrected by glasses.

Generally, it is done after high school, and the effect is good above 500 degrees, and it can basically return to normal.

After the age of 18, my classmates did a good job of doing laser in Wuhan **** at 1400 degrees.

Suitability for excimer laser surgery depends on your psychological needs and the condition of your eyes. If you have your own requirements to remove your glasses, in general, you may be a candidate for laser corneal refractive surgery if your refraction has been stable for two years, your corrected vision is good, and you have no other eye diseases. Of course, the doctor will also do a series of rigorous preoperative examinations on your eyes.

The routine examination before surgery is mainly to ask about the medical history, understand the changes in vision in recent years and the best methods, whether there is a family history of corneal disease related to heredity and corneal dystrophy, etc., and finally decide whether you can do it.

In some cases, it is not suitable to take excimer laser surgery**Myopia, such as eye abnormalities, systemic immune system diseases, pregnant women, etc. are not suitable for surgery. Only those who are 18 to 50 years old, have myopia of 200 3000 degrees, farsightedness of 100 1000 degrees, astigmatism below 400 degrees, and have a stable refractive power for more than 2 years, are in basic health and have no other eye diseases.

At the same time, you should not be too strict about your psychological expectations for the outcome of the surgery. In daily life, vision can be achieved without glasses, which is the basic standard for removing glasses after surgery. Most patients have about the right vision after surgery, which meets the general requirements for joining the army, driving, going to school, etc., and some patients have even reached it.

However, the extent to which you can recover after surgery varies from person to person. You need to be aware of the risks and complications that may arise from surgery so that you can have a realistic expectation of the outcome of your surgery.

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.

I don't think it's recommended to have this kind of surgery if it doesn't have an irreversible impact on your life, after all, it is rumored that it is very risky, and you may lose your sight in old age.

Not everyone can do it, you have to go to the hospital to check whether there are other eye diseases, and then you have to test the thickness of the cornea, which is not possible if the cornea is thin.

It is suitable for people who have time after the college entrance examination, because they have to rest after that, and they can't exercise vigorously...

The advice to you is not to do it, there are authoritative people in many foreign countries who believe that half of the people have sequelae after surgery and now it seems that everything will be fine after the operation, and they need good rest and eye hygiene problems in the future, and most people have a significant loss of vision after ten years.

Laser correction is not feasible, it is very risky, the surgery is not a one-time operation, and as we age, the degree of myopia will continue to decline! For the sake of your health, please wear your eyes and take care of your eyes!

Don't do it, many people around you who have had this surgery will have sequelae of sore eyes and easy fatigue. It is not recommended that you do it.

Just look at what kind of surgery it is, if it's cosmetic surgery, it's better for girls to do it at the age of 10 or 13, otherwise it will make their youth have an inferiority complex.

I also want to have laser vision correction but I'm worried...

Myopia is more than 300 degrees, but this surgery is not recommended.

It is better not to have surgery, some of them will be blind because of the sequelae.

Rich people are suitable for this corrective surgery!

It's better not to do it, the process is irreversible.

It's nothing, I haven't done it yet.

It's better to be cautious about this surgery.

you fuck you shit, i am ready, come on
