What do I need to pay attention to in laser treatment for myopia? Is it safe?

There are three major harms of laser ** myopia: first, the cornea will become thinner and easy to rupture after trauma; Second, if the eye medicine is not strictly prescribed according to the doctor's instructions after surgery, corneal opacity will occur; Thirdly, 10 to 20 years after surgery, it is easy to develop symptoms of dry eyes.

Risks of surgery

The safety of laser correction surgery is related to the doctor's operating experience and equipment. Surgery is not risk-free, and there are two main postoperative complications to avoid. Any cornea that has a wound in surgery will have a chance of infection.

Some of the sequelae of myopia eye surgery are caused by the wound being exposed to the air after the cornea is restored, which can cause inflammation and infection if you do not pay attention to hygiene.

Myopia is to flatten the cornea, but the cornea that is too flat will be squeezed by the pressure from inside the eye, causing the cornea to bulge forward, this pressure is not felt by people, but the consequence is not only not myopia, but will aggravate myopia, and even irreversible astigmatism.

First, the sequelae of myopia eye surgery occur because the hospital does not carefully screen and exclude those patients with congenital eye diseases before surgery.

Second, although qualified patients are screened out, the surgeon's surgical scale is not appropriate when performing the operation. For example, a certain thickness of the cornea should be preserved, but some doctors want to completely correct the vision of patients with high myopia, and cut the cornea too thin, which leads to adverse consequences.

No, there is a very strict preoperative examination before myopia, and if you pass the preoperative examination, the surgery will not be dangerous. The main thing about this surgery is to see the thickness of your cornea and the flatness of your cornea. Surgery is not possible if the thickness of the cornea does not exceed 450 m.

It is recommended that you go to the hospital for a specific examination and then listen to the experts' opinions, after all, it is still your personal choice whether to do surgery or not. lh

In the early post-operative period, you should avoid watching TV and computer for a long time without interruption. Pay attention to eye hygiene, i.e. the time, distance, light, etc. of the eyes.

At present, laser surgery can be used for myopia**, and regular medical institutions are selected for treatment, and in the case of meeting the surgical indications after evaluation, laser surgery ** myopia is basically safe and has a good prognosis; Some patients may have refractive regression due to the influence of their own eye changes and eye status after surgery, that is, the visual acuity level is better just after surgery, but after a period of time, the unaided visual acuity after surgery may be lower than that before surgery, but it will not affect the success rate of surgery.

Myopia laser surgery is an operation performed on the surface of the cornea, which does not touch the inner eye and does not change the structure of the eye, and the excimer laser is ultraviolet light with a very short wavelength, which has a photochemical effect with biological tissues, does not produce heat energy, does not cause thermal damage, and does not scorch the cornea, and there are no unsafe factors.

Not very good, may suffer from eye diseases around the age of 60.
