I am nearsighted at 550 degrees, is it better to have laser surgery or glasses?

The reason why we don't trust doctors is not because medical ethics is a universal social problem.

This is what I replied to yesterday, find it and post it for you to see.

Learn more and make your own choice.

If the anteroposterior diameter of the eyeball is too long, or if the curvature of the lens is too large, the image of the object formed by the refraction of light reflected by distant objects will fall in front of the retina, so that distant objects cannot be seen clearly. It's called myopia.

Myopia surgery is a means of adjusting the refraction of incident rays through the modification of the cornea, so that the image falls on the retina, which is essentially the same as glasses, and does not change the structure of the eye and lens in the essence of myopia.

1. The technology is very mature, and if it can be done after inspection, it can be done above 1000 degrees.

2 Since the essence of myopia surgery is the same as that of glasses, if you use your eyes improperly, the anterior and posterior diameter of the eye will continue to increase, and the curvature of the lens will increase, and you will become myopic again, which is actually the same as the increase in the power of glasses.

Therefore, the specific time and power are inconclusive, and it all depends on your eye habits.

3 The cost is generally 2000-5000, mainly depending on the hospital you go to, the equipment for the operation, etc.

4 Really do a good job should be corrected.

5 All surgeries are risky and will be asked to sign before you do the surgery.

Note: Not recommended.

You're only 400, huh? My eyes were almost 600 degrees. It is not recommended to do it now. I heard that the deeper the myopia, the more effective it is, and it is not easy to do it**. It is best to do it above 800 degrees.

Just a suggestion!

See when the doctor rushes to do it, and you can rest assured if you do it again. At that time, all aspects were very mature, and the people who did the surgery were not experimental objects like mice. If you want to be a guinea pig, do it.

500-degree myopia is considered moderate myopia and can be surgically surged**. If you want to have myopia surgery, you must first meet the following conditions: First, you need to be at least 18 years old.

Second, there has been no significant change in myopia in the past year. Third, there must be no active inflammation in the eye. For example, conjunctivitis, keratitis, dacryodenitis, dacryocystitis, blepharitis, etc.

Fourth, there should be no diseases in the whole body that are not suitable for surgery. For example, diabetes, immune diseases, etc.

It is necessary to go to the hospital for an ophthalmologist examination, measure the corneal curvature, corneal thickness and other indicators, and finally determine whether the operation can be performed, and then arrange the appropriate time for the operation**.

Just bring glasses. No surgery is required. It's not a big deal either. No surgery is required. Liver blood insufficiency. You go under the knife. It's useless either.

If 500 degrees of myopia occurs, corneal refractive surgery is generally suitable**Myopia. Corneal refractive surgery includes excimer laser surgery, femtosecond laser surgery, femtosecond laser surgery, corneal surface cutting, etc., which should be selected according to the specific situation, and various surgical methods are different, and should be selected according to economic conditions.

Knowledgeable to see what kind of myopia surgery is suitable for me with 500 degrees of myopia? I think 500 degrees of myopia is suitable for laser surgery.

I went to the hospital to check the fundus topography to know if I could do surgery, but there was no result without examination.

Surgery is risky, and not everyone is suitable for myopia surgery, and it is necessary to go through a series of examinations to know whether it is suitable for surgery, and there is no guarantee that myopia will not be done after surgery.

Patients with 100 to 1200 degrees of myopia can have laser surgery. In general, the smaller the prescription of a myopic patient, the better the effect of laser corneal refractive surgery. Whether it is full femtosecond or half femtosecond, the patient has to remove some corneal tissue, and the higher the degree of myopia, the more corneal tissue the patient removes, and the cornea will become thinner accordingly.

Corneal laser surgery should not be performed without other eye diseases, such as glaucoma, cataracts, etc. These diseases themselves can cause vision loss, and if surgery is performed, vision may not improve well or even not after surgery.

Laser surgery is a part of corneal refractive surgery, which uses a laser to cut the cornea and change the thickness of the cornea, thereby changing the superficial surface morphology of the cornea and correcting vision. Because after the cornea is cut, the remaining thickness of the cornea generally cannot be less than 1 value, and it is generally recommended that it is better to be more than 280m, that is to say, the thickness of the cornea left after surgery is too thin, and the probability of postoperative complications will increase, so it also limits corneal refractive surgery to correct a certain range of myopia.
