Are there any sequelae of laser correction surgery for myopia?

The biggest sequelae after myopia surgery is the possibility of having **, under normal circumstances, the time of this ** is about 10 to 20 years, and the length of time is determined by whether we specifically protect our eyes, although many **myopia institutions now promise to have two or more surgeries, but I personally think this statement is still not very reliable, because the process and technology of surgery have not been revolutionized, in order to ensure the health of our eyes, We still try to have only one operation, of course, after an operation to try to prolong the time, we should do the following to protect our eyes in daily life:

1. Don't use your eyes for a long time.

First of all, the first point should be done is not to use the eyes for a long time, because long-term eye use is one of the most common factors that damage our eyesight, no matter how busy we are studying or working, we must make reasonable relief after using our eyes for a period of time, I suggest that everyone should relax their eyes for 5 10 minutes every hour of work or study, so that our vision can be guaranteed to the greatest extent.

2. Do eye exercises often.

In fact, so far, eye exercises are still the best massage method to protect the eyes, there is no one, I believe that eye exercises are already very familiar to everyone, because in the process of 9 years of compulsory education, we have to do 1 2 times almost every day, although it has not been done for a long time, but as long as we re-do it again 1 2 times a day, we can protect our eyesight very well.

3. Eat more foods that are good for your eyes.

In addition, we should also eat more foods that are good for the eyes, common foods that are good for the eyes in daily life are animal liver, carrots, deep-sea fish oil, etc., eating these foods regularly can help us protect the vision of the eyes, if we usually use our eyes more frequently, then I recommend that you eat at least 1 2 times a week.

The sequelae of laser myopia surgery are generally as follows: First, dry eye syndrome, dry eye syndrome is a very tricky eye disease, and at present, it is also some symptomatic, and it cannot fundamentally solve dry eye syndrome.

Second, it can be complicated by severe keratitis, such as viral keratitis, and corneal transplantation is required in the most severe cases. Thirdly, there will be a regression of vision, which will return to the original state or be slightly better.

Fourth, the corneal flap dehiscence caused by accidental collision after surgery is complicated by a series of other serious complications. Fifth, if there is a possibility of keratoconus, corneal transplantation can only be treated.

If the postoperative visual acuity is good, the quality of the vision mainly depends on the suturing technique, whether there is rejection or other factors.

Myopia laser correction surgery may have sequelae, the more common sequelae, such as dry eye and vision regression, if the doctor is not particularly skilled in the operation at the time of surgery, it may induce secondary glaucoma. Before undergoing myopia surgery, you need to go to the ophthalmology department of the hospital for relevant examinations, check the specific eye condition, and then choose a suitable surgical plan. After the surgery, you need to keep your eyes clean and hygienic, and try not to look at your phone for a long time.

It's better to go to the local area to see, Linyi Aier is famous locally, it has been more than ten years, and it is guaranteed.

There will be sequelae and it is constantly improving. The most important or sequelae of this type of surgery is generally corneal opacity or corneal thinning, rather than corneal inflammation. If the corneal inflammation is caused by surgery, it should not occur more than 10 years later, but should occur within a short period of time after surgery.

With the accumulation of clinical experience of doctors, the incidence of such cases is decreasing, and the vast majority of patients can achieve accurate vision through surgery.

In view of the "glare" at night, mainly because people with large pupils are prone to such complications, personalized technology can be "tailored" according to the characteristics of large pupils, which can effectively reduce the occurrence of complications.

The current problems and drawbacks of laser ** myopia are also obvious: because this surgery has not been available for a long time, ophthalmology experts have not been able to count and determine its long-term effect; Some patients order eye drops for a long time after surgery, otherwise their eyes will be dry and uncomfortable, and some even require eye drops for a lifetime. In addition, the following complications are prone during and after surgery:

1. The corneal flap is off-center, the corneal flap is not in good alignment, the corneal flap is folded, and the corneal interlaminar debris or blood remains;

2. The laser cutting is off-center, and the corneal knife cuts through the cornea;

3. Postoperative lifelong glare and dazzling: myopia is more common in height, and there is halo when looking at things;

4. Under-correction or over-correction: In this case, another operation will be required, and the effect after the reoperation is not very ideal;

5. Visual acuity**: especially for patients with high myopia, vision begins to decline a few years after surgery;

6. Best-corrected visual acuity decline: after surgery, the visual acuity that can be achieved when wearing glasses cannot be achieved;

7. Dyslexia, dry eye, decreased corneal sensitivity, pain;

8. Irregular astigmatism: almost all patients have varying degrees of irregular astigmatism after surgery.

9. Corneal infection, diffuse interlamellar keratitis, formation of corneal insula:

10. Degeneration or scarring of the corneal periphery, corneal center pigmentation.

Laser correction surgery for myopia is generally free of sequelae. At present, with the development of science and technology, the laser machine has been updated, and the accuracy of surgery has been further improved, so that the uncomfortable state of patients has been significantly reduced. For example, the corneal thickness of a normal person is about 520 m, and if the corneal thickness is less than 500 m or only 450 m, it may not be suitable for myopia eye surgery in this state.

If correction is done in this state, there is a possibility that there will be sequelae, so it is necessary to do a detailed and accurate test before surgery.

There are sequelae of myopia laser surgery, mainly including: 1. Decreased night vision, which almost all patients who have undergone myopia eye surgery will experience, but with the slow delay of the operation, this symptom will gradually be reduced or even disappear. Second, the sequelae of night glare may not disappear completely, and most patients will not have any impact on their lives after they are fully adapted; 3. Dry eyes, which is also a common phenomenon after myopia surgery.

Myopia laser surgery has no effect on fundus diseases, lens lesions, etc., and will not increase the incidence of these eye diseases.

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.
