Can the eye have multiple lasers? How many times can I do laser surgery for myopia?

There are a certain number of laser surgeries for the eyes, and you can't do it casually a few times, but only once under normal circumstances, and it will become thinner if you do it more times, and the effect is not good, which is harmful to the eyes.

Hello, I think it may be related to the fact that after the surgery, I did not pay attention to good maintenance, which led to myopia again. It is recommended that myopia laser surgery is mainly through the change of corneal thickness, so that the refraction changes, generally can not be done for the second time, at present, the main thing is to wear appropriate glasses for correction, if you really do not want to wear glasses, you can consider doing myopia intraocular lens implantation, but you need to pass the examination.

Under normal circumstances, corneal laser surgery is a procedure to alter the refractive state. Normally, corneal laser surgery can only be done once, and if the cornea is operated on again, it will become thinner and more dangerous, which is not a safe corneal thickness range.

Corneal laser surgery is a procedure to alter the refractive state.

Myopia laser surgery can be done several times, mainly related to the residual corneal thickness after surgery, if the corneal thickness is sufficient, it can be operated on multiple times, and there is no upper limit to the number of surgeries.

Because laser myopia surgery is actually a part of the corneal tissue, which is equivalent to carving a lens on the surface of the eye, so as to achieve the purpose of changing myopia. When the cornea is thinned to a certain extent, the pressure of the eye on the outside world will be reduced, and some complications will occur. Before myopia laser surgery, the doctor will do a detailed preoperative examination for the patient, according to the patient's eye myopia degree, corneal thickness, astigmatism and other parameters, a comprehensive determination of the surgical plan, if the patient's corneal thickness is sufficient, it is possible to do two surgeries, but if the cornea is already very thin, it is not possible to do two surgeries.

We know that myopia surgery is now very mature, and adults often choose to use this surgery to say goodbye to glasses, and now myopia surgery has developed to the stage of full femtosecond laser and half femtosecond laser, and the accuracy of this surgery is very high.

In daily life, people often ask how many times can myopia laser surgery be done, in fact, generally speaking, one time can often be successful, do not need to be carried out many times, of course, if there is still a certain degree of regression after one time, or after a few years of myopia or astigmatism, in this case you may need to have a second surgery, but before these surgeries, you must also see if the cornea can withstand it.

We know that the principle of surgery is to cut the cornea, and the more times you do it, the more times you cut the cornea, the more the cornea will continue to thin, so as for how many times you can do it, you must look at the cornea's bearing capacity.

Ingredients: 400g of dried fragrant ingredients: appropriate amount of vegetable oil, 3g of salt, 4g of chili powder, 3g of Sichuan pepper powder, 4 teaspoons of sesame pepper red oil, 2g of sugar, 2g of dark soy sauce, 5g of white sesame seeds, 3g1 of pepper, prepare raw materials.

2. Cut the dried incense into strips. 3. Heat the pan with cold oil, and the oil is hot for 8 into fragrant dry. 4. Fry until the skin is golden and 8 mature, remove and drain the oil.

5. Leave the bottom oil at the bottom of the pot, add sugar and fry over low heat to melt. 6. Add Sichuan pepper powder, chili powder and pepper and stir-fry evenly. 7. Add the fried fragrant dried.

8. Add dark soy sauce and salt. 9. Stir-fry the pepper and red oil evenly. 10. Add white sesame seeds.

11. Wrap the seasoning around each dried incense. 12. a finished product.

Myopia laser surgery can be done for the second time, but it is necessary to accurately measure the corneal curvature, refraction, thickness and corneal morphology according to the change of the cutting thickness and corneal curvature of the first operation. [10s to test which correction plan is suitable for me].

Myopia surgery can basically achieve good vision results in a single operation, but as the number of surgeries increases, some people will have various problems. There are two common groups of people who undergo secondary surgery: one is low-grade myopia after surgery, such as 800-degree myopia in the past, and 100-degree myopia was recently found after surgery.

There is also a type of vision that often occurs when driving at night, although the vision is good after surgery, but there is a halo when driving, which is called poor visual quality.

The above two groups of people need to be corrected by secondary surgery, and the most important thing to pay attention to before the second operation is the thickness of the patient's cornea, if the corneal thickness is sufficient, a second operation can be considered. For poor visual quality, it is necessary to repeatedly check the possible causes before surgery, and even repeatedly measure and analyze the corneal topography map and corneal aberration map. If the problem is identified first, the same problem is always present and the reproducibility of each examination is good, and then a second operation can be considered.

If the patient's eye condition is unstable, it is not suitable for a second operation.

If you want to know more about myopia laser surgery, we recommend consulting Beijing Mingshi Ophthalmology. Beijing Mingshi Ophthalmology Department is a professional ophthalmology hospital, which has been unswervingly committed to the past 11 years, and has gradually grown into a professional brand of myopia medical treatment in China. With the mission of "reducing the incidence of myopia in China and improving the happiness of myopic people", the Department of Ophthalmology takes the lead in the country to open the first action of popularizing eye health knowledge among adolescents, disseminates the concept of healthy growth, and makes unremitting efforts to achieve the goal of "Healthy China Action" as soon as possible.
