What are the current risks of myopia eye surgery?

1.Undercorrection or overcorrection: Myopia remains after surgery, or the correction degree exceeds the expected degree and becomes hyperopia, which is the most common***, and can be laser corrected again after the degree is stabilized depending on the situation.

2.Photophobia: Sensitivity to light increases within 3 to 6 months after surgery, but it usually fades away after 6 months, and rarely persists.

3.Glare or diplopia: It is more common in the early stages of surgery, especially at night, when the pupils become enlarged, most of which will disappear slowly, and only a small number will last.

4.Complications during surgery: most are poor corneal flap cutting, such as incomplete or uneven cutting; The flap can be restored by repositioning the flap and can be operated on again after three months.

Generally speaking, the success rate of this type of myopia surgery in large hospitals is higher. Getting out of misunderstandings and evaluating scientifically and objectively is a rational attitude. Objectively speaking, the safety of the current excimer laser surgery is relatively high, and compared with the earliest radial keratotomy surgery for myopia with diamond knife, its safety has made a qualitative leap, which has been fully proved by a large number of clinical practices for more than 10 years.

Of course, good surgical equipment, skilled operation and rich experience of the surgeon, as well as good cooperation of the patient, are the basis for the high safety of the operation.

The disadvantages of myopia eye surgery are undercorrection, regression, and vision loss after surgery. In addition, there may be fluorescence night vision impairment after surgery. There is also liver inflammation and severe keratitis.

In addition, there is a possibility of accidental collision, which can cause the corneal flap to dehisce. Therefore, myopia surgery is not allowed to be over 18 years old, and the myopia degree is between 100 and 1,500.

Myopia laser surgery: In the case of incision of corneal tissue, the stromal layer under the cornea is cut to achieve correction, laser myopia eye surgery is a surgery to cut part of the healthy corneal tissue.

The simple pursuit of vision improvement to destroy diseased tissues is the disadvantage of laser surgery, and it is also the greatest sorrow in the medical field, after this surgery, if the intraocular pressure increases, vision loss and other sequelae, complications are inevitable.

Many people who have had surgery will find that the doctor who operated on them wears glasses, so why not choose laser surgery when they claim that there are no sequelae and complications?Laser myopia eye surgery is not as good as it is reported.

Now there is an argument that laser surgery for myopia is very mature, so you don't have to be afraid. However, no matter how advanced the technology is, no matter how advanced the machine is, as long as it is a traumatic and destructive operation on the healthy cornea, the corneal tissue cannot be regenerated, and the damage caused to the corneal tissue is irreparable.

Myopia eye surgery usually refers to corneal refractive surgery, including excimer laser surgery and femtosecond surgery, which has been widely carried out in clinical practice, and its efficacy is relatively certain, which can effectively improve corrected vision. However, because this operation is invasive, it is bound to bring some common complications, such as postoperative overcorrection, undercorrection, refractive regression, dry eye syndrome, optical aberration-related claims, corneal interlaminar debris, corneal neurotrophic epithelial lesions, diffuse interlamellar keratitis, infectious keratitis, progressive corneal ectasia, etc., but the probability of these complications is relatively low compared with the necessity of surgery.

If you pass the preoperative examination for myopia surgery, there is no risk, and the surgery is very mature.

It is still possible to do myopia correction now, femtosecond recovery is faster, and the corrected vision can meet the standard of joining the army.

You can consult and compare a few more, and then choose the one that suits you.

Generally, there are special discounts for joining the army, civil servants, etc., so please consult more.

Laser myopia eye surgery is recognized by the national military recruitment department, and the surgical technology has been very mature and the safety of the operation has been recognized so far.

Excluding the waiting time before and after the surgery, you can complete the surgery in 5-10 minutes alone, and you will have good vision on the first day after surgery, basically the best vision you can see with glasses before the surgery.

A small number of patients who have just undergone myopia surgery may have temporary discomfort, such as dry eyes, glare, etc., but most of these symptoms will gradually disappear with postoperative medication.

The risk and sequelae are that some inflammation is caused by infection after surgery, and when doing surgery, the doctor does not operate properly, and there are some phenomena such as insufficient postoperative correction effect or damage to the cornea, and it may make the patient have presbyopia symptoms after many years, but at present, myopia eye surgery is more common, and the equipment is relatively complete, and the safety is relatively high when you go to a regular eye hospital to operate.

Complications are possible with any surgery. Postoperative corneal healing delay, or undercorrection or overcorrection of refraction, some complications are prone to occur during the surgical process or after surgery, laser cutting off-center, corneal knife cutting through the cornea, lifelong glare and glare after surgery, which is more common in patients with high myopia, halo occurs when looking at things, and there may be undercorrection or overcorrection, in this case, it is necessary to perform surgery again, and the effect of another operation is not particularly ideal. For patients with high myopia, there will be a chance of vision** a few years after surgery.

In the twenty or thirty years of myopia eye surgery, in the past four years, what are the sequelae, and whether it is good or not?

At present, there are two main types of myopia surgery: one is corneal refractive surgery, which is what we usually call myopia laser surgery; **Four or five thousand to one or two hundred thousand, the other is lens refractive surgery, including lens posterior chamber intraocular lens implantation surgery (i.e., ICL implantation) and clear lens replacement surgery** is generally more than 30,000.

Only after the preoperative examination will you know which surgical options you can choose. Only what suits you is the best, not the more expensive the better.

At this stage, myopia surgery is mainly excimer laser surgery, which includes full femtosecond laser surgery, femtosecond laser plus excimer laser surgery and full excimer laser surgery, all of which have certain risks. The main risks of these surgical methods are: first, the risk of infection that comes with any surgery.

If you encounter a serious infection, it can affect your vision and even lead to the removal of the entire eyeball, and of course the occurrence rate is very low. Second, the problem of refractive regression, there are very rare cases after surgery that myopia may reappear, which is called refractive regression. Third, individual patients will have corneal opacity after surgery, the medical term is haze, there is a certain chance of appearing, but through hormone eye drops, haze can slowly subside.

Fourth, some people will have keratoconus after surgery, and it is necessary to have a detailed examination of the cornea, and patients with a tendency to keratoconus are prohibited from surgery. Fifth, if you have dry eyes after surgery, some patients will feel uncomfortable with dry eyes and astringent eyes. Sixth, because the corneal range of surgical cutting is not the whole cornea, about 6-8mm, some people will use the peripheral cornea to see things after the night due to the dilation of the pupil, which will cause glare, such as looking at the lights at night will show halos around the periphery.

At present, more than 20 examinations will be done before myopia surgery, in addition to visual acuity examination, slit lamp examination, comprehensive optometry, corneal topography examination, non-contact intraocular pressure examination, corneal thickness measurement and other routine items, if necessary, tear test, corneal morphology examination, contrast sensitivity and glare and other special items are also required.

There are definitely risks associated with myopia eye surgery, no matter what kind of surgery it is, whether it is a high-level surgery or a low-level surgery, whether it is a difficult operation or a small difficult operation, there will be risks of surgery, and there will be complications of surgery. However, at present, the probability of these risks is very small, because before the operation, the doctor will often check the pass, and often ask the patient to improve the relevant examination, look at the specific condition of the patient's eyes, see if it meets the indications for surgery, whether it is within the safe range, only within the safe range can the surgery be done, if it is not within the safe range, do not meet the indications of surgery, it is impossible to perform myopia eye surgery. Of course, the development of myopia eye surgery technology is also very fast, and it has reached the stage of full femtosecond laser surgery, which is to use femtosecond laser for cutting the whole process, which is very small and recovers very quickly.

The risks of myopia eye surgery are:1There may be an infection after surgery, either in the eye or in the conjunctiva and cornea.

2.Myopia may be overcorrected, or the correction may be undercorrected. 3.

Some patients experience halos or glare. 4.Poor postoperative care and failure to maintain good habits may lead to refractive regression after surgery.

5.There may be dry eyes. 6.

The cornea will have new blood vessels. 7.The cornea is dilated, etc.

There are risks associated with any kind of surgery, and these are some of the conditions that may occur after refractive surgery, but they generally do not occur. Before the operation, you just need to prepare strictly according to the doctor's instructions, and then keep a good mood, relax, and don't think too much. After surgery, you should pay attention to hygiene and do not overuse your eyes, as the risk of risk will be greatly reduced or even non-existent.
