How Do I Choose the Best Eye Laser Surgery Center?

Myopia surgery generally refers to excimer laser treatment for myopia surgery. The so-called excimer laser refers to the laser generated by the stimulated dimer. The reason why it is called an excimer is that it is not a stable molecule. It is a molecule that has been formed in a series of physical and chemical reactions caused by the excitation of external energy by laser energy, but has a fleeting life. Ten nanoseconds.

Myopia surgery

Myopia surgery, generally refers to excimer laser treatment of myopia surgery, the so-called

Under eighteen

Under 18 years of age is not suitable for surgery, surgery requires the patient's refractive state is stable. Refractive states include myopia, hyperopia,

The consultation before the initial diagnosis allows patients to have a certain understanding of refractive surgery methods and treatment procedures, and at the same time to answer questions and eliminate concerns for patients, so that patients can better cooperate with doctors for examination and treatment. The initial examination is a test and understanding of the patient's eye and physical health to determine whether it is suitable for refractive laser surgery.

Patients must complete the medical history questionnaire accurately so that the doctor can fully understand your physical condition. After the initial diagnosis, you can roughly determine whether you are suitable for laser surgery. There is also a general concept of the expected effect of the surgery. If the conditions are met, our doctor will recommend different surgical methods according to your test results and other conditions, and make appointments for the corresponding follow-up inspection items and time. At the same time, you must pay a certain inspection fee to ensure the next inspection goes smoothly.

Initial inspection items: vision, refractive power, fundus (pupil dilation), intraocular pressure, understanding of the patient's medical history,

Myopia surgery is mainly performed on the cornea of the eye, but there are no blood vessels on the cornea, but there are nerves, so you have no pain during the operation. During myopia surgery, good cooperation with the patient is an important prerequisite for the success of the operation. Therefore, in myopia surgery, patients should pay attention to the following points:

1. Relax and don't be nervous.

2.Don't squeeze your eyes hard, don't move your eyes randomly, and fix it according to the doctor's guidance.

3. At the critical moment of the operation, follow the doctor's advice, do not speak, and do not allow disorder.

4. Be sure to stare at the blinking red or green fixation lamp during the operation. Even if you can't see the fixation lamp, don't move it. Follow the doctor's guidance to gently move the eyeball without moving the head.

5. On the operating table, do not touch the surgical disinfection area with your hands.

1. Pay attention to regular follow-up of medication

A successful excimer laser surgery depends not only on the doctor's superb surgical technique, but also on regular medication and follow-up after surgery. The use of excimer laser medicine is particularly important. It should be used in accordance with the doctor's instructions. Do not stop or abuse it arbitrarily because you feel good about yourself. At the same time, follow up at the hospital regularly. Otherwise, it may cause sequelae of excimer surgery. There was a college student who had a very successful operation. The visual acuity of both eyes was 1.5 after 1 week of postoperative review, but he never returned for inspection. After 2 months, he had to return to the clinic for a sharp drop in vision. The inspection revealed that the visual acuity was 0.4 and the intraocular pressure reached 35mmHg. . Following up on his medical history, it turned out that he has been using hormone eye drops. He thinks that his vision is normal and does not go to the hospital to check the intraocular pressure. He pays attention only when there is a decrease in vision. Although the intraocular pressure has returned to normal after active treatment, his vision can only recover 0.8. Excimer laser surgery usually uses hormone eye drops for 1 to 2 months, the purpose is to promote postoperative recovery and prevent myopia regression. Hormone eye drops have the potential to increase intraocular pressure, leading to hormonal glaucoma. Therefore, during the administration of excimer laser surgery, it is necessary to regularly check in the hospital, especially to follow up the intraocular pressure. In addition, for LASIK patients, due to the presence of the corneal flap, external forces should be avoided to collide with the surgical eye after operation to avoid serious consequences of corneal flap displacement.

2.Be careful of high myopia

Long-term myopia patients are often accompanied by retinal pathological changes, especially those with high myopia. The peripheral retina is thinner and atrophic. Once a retinal hole appears, it may lead to retinal detachment.

Due to the lack of related knowledge, people's understanding of myopia surgery generally has the following five major misunderstandings.

Misunderstanding 1: There is no age limit for laser surgery

Misunderstanding 2: Laser surgery can be done at any degree

Misunderstanding 3: Laser surgery is not necessarily safe

Myth 4: Only treat myopia but not astigmatism

Myth 5: Myopia will "bounce" after surgery

1,

The patient himself has a request for lens removal.

Be at least 18 years old (preferably 20 years old).

The diopter has been stable in the past two years.

Corrected diopter range: Myopia should not exceed 1500 degrees, astigmatism should not exceed 600 degrees, and hyperopia should not exceed 600 degrees.

Refractive error.

Those who are wearing contact lenses: stop wearing soft lenses for more than 2 weeks, stop wearing hard lenses for more than 3 weeks, and stop wearing OK lenses for more than 1-3 months.

Corneal thickness is greater than 450 um (depending on refractive status).

No active diseases of the eyes.
