Who is suitable for myopia laser correction surgery?

As an adult, you may opt for myopia laser surgery if you meet the following criteria:

Six adaptation conditions.

Only patients who have the following conditions are candidates for LASIK surgery**

1.Age 18 years old or above;

2.In the past two years, the diopter has been stable, and its development rate is not more than 50 degrees per year;

3.There are no contraindications to LASIK surgery (such as glaucoma, iritis, fundus hemorrhage, omentum detachment, etc.) in eye examination

4.No systemic diseases such as diabetes, immunity, collagen, etc.; Non-scarring constitution;

5.The diopters are in the following range: myopia 100 3000 degrees; Hyperopia above 800 degrees; Astigmatism below 600 degrees;

6.The corneal thickness is greater than 450um.

Seven major contraindications The contraindications mainly refer to active inflammatory lesions in ocular patients, including conjunctivitis, keratitis and chronic dacryocystitis.

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**.

Try not to go for laser surgery, because it is easy to get things to happen when you are driving after you are done, and I have a colleague who is like this, because the laser operating room removes a layer of cornea from your eye, so if you have a strong light piercing in when you drive, your eyes will not be used to and cause vertigo.

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

Yes, more than 200 degrees are very low, the effect should be very good, according to your current situation, it is not a problem to achieve it after surgery If you are from Fujian, it is recommended that you can come to Quanzhou New Vision Eye Hospital. . .

Trouble, thanks!

It is not an ophthalmology specialty, so I will integrate the information from the Internet. Here's the answer:

The principle of laser surgery is to grind the cornea into glasses in the simplest terms, and then you don't need to wear glasses.

Seriously do a good job of preoperative examination, in a reliable hospital, the risk of this surgery is quite good at present, less than 0.5% of the corneal procedure continues to thin rate, in fact, more reliable than the vast majority of surgeries.

Students with too high myopia should be cautious when doing surgery, the higher the degree, in order to change the refraction, the cornea must be shaved more hard (imagine the image of the middle of the glasses that have always been high in the middle and the outside is extremely thick, and the psychological spectrum will be a little spectrum), and the risk after surgery will of course be greater. Generally speaking, six or less is considered a safe boundary, but at present, there are no experiments that can accurately support this conclusion.

In principle, after the fibers of the corneal stromal layer are severed, there will be a certain degree of scattering of light when passing through, and if the pupil is dilated in a dark environment, it will increase the possibility of glare and reduce contrast sensitivity. In other words, when the person is in good light, there is no problem at all, but when the light is low, it is possible that the vision will be greatly reduced. Therefore, all people who need to work in a dark environment for a long time, such as drivers, doctors, etc., must be cautious before doing this surgery!
