Go to Huizhou central hospital to do vision correction operation

1. Many people who have had laser myopia surgery will find that the doctor who operated on them is wearing glasses
why don't they choose laser myopia surgery when they claim it won't proce sequelae and complications? Do not want to do not understand, through the above introction, we all know that laser myopia surgery is not as good as the outside world
although there is an argument now that laser surgery for myopia is very mature, we should not be afraid. However, no matter how advanced the technology is and how the machine is updated,
as long as the corneal tissue is operated on in a traumatic and destructive way, the corneal tissue will not be renewable and the damage to the corneal tissue can not be recovered
this is also the main reason why Professor Cai Ruifang of Taiwan took the initiative to seal the knife and refused to do laser myopia surgery again. This kind of argument is just a trick for the vested interests to bewitch the uninformed masses. We must not be deceived
for myopic friends, among the methods and technologies to improve eyesight on the market, only the physical method does not damage the corneal tissue, so the reversible method is reliable. Therefore, I hope you must weigh the pros and cons before choosing laser myopia surgery, so as not to regret after doing it.

2. 1、 Understanding myopia surgery
myopia surgery has been carried out in China for nearly 30 years. It has experienced the development process from rk and PRK to traditional excimer laser surgery, and then to half femtosecond laser, full femtosecond laser and ICL crystal implantation in recent years“ In short, the current mainstream myopia surgery is mainly divided into femtosecond laser and ICL crystal implantation Myopia surgery can correct myopia by changing the corneal refractive power. With the continuous development of medical technology, myopia surgery is also moving towards a more minimally invasive and high-quality direction< Second, understand the vision requirements of the intended major
in military academies, such as flight technology, navigation technology, fire engineering, criminal science and technology, reconnaissance, marine technology, marine science, measurement and control technology and instruments, the vision requirements of candidates are very high. Therefore, it is an urgent task for the candidates who intend to fill in this kind of volunteer to correct their eyesight through myopia surgery in order to reach the physical examination standard< Third, plan the operation time in combination with the physical examination and holiday arrangement
after a short rest at the end of the examination, candidates can not completely relax, so it is necessary to know the physical examination time in advance and plan the operation time for myopia. Generally speaking, the fastest operation takes three days, one day inspection, one day operation and one day review. Therefore, candidates must plan ahead of time, do not wait until the physical examination, to do surgery, should try to leave some recovery time for the eyes< 4. Hospitals and doctors for myopia surgery. Many myopic candidates have been treated by myopia surgery with fast operation time and good visual quality. However, do you know that in the operation process, the operation hospital and the surgeon play an important and irreplaceable role! Therefore, before the operation, patients must "find out" the operation hospital and doctors. The development of any kind of myopia surgery requires the hospital to have a professional operation quality control system and a highly skilled medical team with a large number of operations< Five, professional and strict preoperative examination
myopia surgery is not everyone can do, so it is particularly important to make a comprehensive assessment of the patient's eye condition and physical condition before surgery. Myopic surgery 18 preoperative check about 2 hours, many patients will ask, "check 2 hours, surgery 10 minutes, is not putting the cart before the horse?" In fact, most of the hidden dangers of myopia surgery lie in the preoperative examination, so whether the operation indications are strictly controlled or not is related to the safety and long-term effect of surgery< 6. Preoperative preparation and intraoperative cooperation
1. Eye drops should be given 1-3 days in advance, which will be arranged by the doctor after general examination
2. When going to bed at night, lie flat on the bed, exercise your eyes to gaze at a point above, keep your eyes from blinking and turning, so as to improve the cooperation degree of laser irradiation ring operation
3. The diet should be light and easy to digest on the day before operation
4. Follow the doctor's advice and cooperate strictly ring the operation< Follow the doctor's advice, recheck and order medicine on time, and pay attention to the reasonable use of eyes
2. One month after the operation, avoid dirty water, bath liquid, shampoo, etc. in the eyes, do not swim within half a year, and do not dive within one year
3. Eyes should not be collided by trauma after operation, and no heavy physical labor and strenuous exercise should be carried out within three months
4. Don't smoke, drink or spicy in a month.

3. If you want to have an examination, it depends on the thickness of your retina.
if you can't do it because it's too thin, you should have a funs and vision examination before laser surgery. Generally, the operation can be completed in about 20 minutes. Don't overuse your eyes after surgery

4. Myopia surgery is divided into preoperative examination, intraoperative cooperation and postoperative care
preoperative examination process
myopia surgery is not suitable for everyone and has strict contraindications. 20 preoperative examinations are perfect and comprehensive, which can not only judge whether the patient is suitable for myopia surgery, but also provide reliable data for surgery, which is the necessary condition to ensure the safety of surgery and obtain the ideal vision after surgery. Preoperative examination should also exclude the patient's eye diseases, such as active inflammation of the eye, which needs to be cured before surgery. If there are keratitis, glaucoma, keratoconus, retinal detachment and other diseases, it is not suitable for immediate myopia surgery. In addition, patients with immune diseases, allergic diseases and severe psychosis are not suitable for surgery
cooperate with the operation process
the operation time of myopia is about 10 minutes. All laser smart, smart femtosecond, precision carving myopia operation, ICL lens implantation and so on will not feel uncomfortable in myopia operation. The operation must be carried out according to the doctor's guidance. Patients need to cooperate in the operation, and the degree of cooperation of patients will play a very important role in the operation effect
postoperative care
the eyes can be used normally the next day after surgery. However, we must follow the doctor's advice after the operation. If the operation is successful, it still needs maintenance and scientific and reasonable eye use.

5. 1、 Preoperative preparation process:
1. Before entering the operating room, the itinerant nurse should confirm the patient's name, age, address, operation mode and other information, so as to ensure that the patient's identity corresponds to the data entered by the equipment one by one
2. After checking the information, the patient was anesthetized. Topical anesthetics were applied to the operating eye 1-2 times, and then the patient was guided to lie down on the operating bed with his hands naturally on the side of the body and his head in the right position
3
4. The operation assistant checks the patient's information again< (2) operation procere:
1. The eyelid opener was placed to fully expose the operation site, and the eye was slightly uncomfortable. Follow the doctor's instructions and look straight ahead
2. When the eyeball is fixed by negative pressure suction and the surgical instrument is close to the ocular surface, the fixation light will appear in the field of vision (Zeiss visumax laser is a green highlight, and the fixation light of different equipment is different), and the highlight may disappear ring the operation. Don't be nervous and afraid, and continue to stay in place
3. Laser scanning ends in about 20 seconds, which is a key process and must be persisted< All femtosecond surgery: after the laser scanning, the lens is separated and then removed. This step is manually operated by the surgeon with the instrument, following the command, and keeping the eyeball still until the end of the operation
B. half femtosecond surgery: after femtosecond laser scanning, the corneal flap was made, then the corneal flap was lifted, and the eyeball was fixed for excimer laser ablation, about 10-20 seconds. The corneal flap was repositioned, the wound was rinsed, and the bandage lens was placed. In the process of excimer laser cutting, there will be a crackling noise, or a smell similar to burning hair, which is a normal phenomenon, so there is no need to be nervous< At the end of the operation, the itinerant nurses will send the patients out of the operating room to the rest area for preliminary observation and rest
2. At the end of the operation, the surgeons used a microscope to check the wound, confirmed that the operation was normal, dropped anti-inflammatory drugs, and the nurses sent the patients out of the operation area< 4. Precautions:
1. Keep the whole body relaxed ring the operation, do not shake the head or turn the eyes
2. Don't speak ring the operation, be sure to fully follow the instructions of the surgeons and surgical assistants, and don't respond to the instructions in any form
3. Keep the limbs still and do not adjust the sterile hole towel by hand. In case of touching by mistake, inform the operation assistant to replace it in time before the operation
4. Keep a calm mind, don't resist the doctor's command, and be sure to fully cooperate
the emergence of surgery is not only a great innovation in the history of human medicine, but also an important symbol of modern medicine. Countless patients benefit from this, to overcome the disease, and even escape from the hand of death. The significance of myopia surgery for ophthalmology is also very important. Countless patients have been able to recover their vision through myopic surgery, making the world in their eyes glow with its original clear and bright color.

6. How is the process of eyesight correction operation? Please tell me what you have done, thank you.
it's troublesome. You can ask your family to accompany you and take care of them for two days,

7. Briefly introce the operation process of the current mainstream four types of myopia surgery
1. Half femtosecond: half femtosecond requires two devices, one femtosecond laser device and one excimer laser device. First, a corneal flap (about 20 mm) was made by femtosecond laser, then the flap was opened, and a part of the cornea was ablated by excimer laser on the corneal stroma (similar to the principle of concave lens). Finally, the flap was reset to correct myopia
2. Full femtosecond: the operation is completed by one device in the whole process. There is no need to make a corneal flap ring the operation, only a small incision of 2mm is made on the cornea, and then femtosecond laser is used to hit the stroma layer, and the transparent stroma is removed from the small incision
3. Thousand frequency smart all laser: it belongs to surface surgery, which is different from half femtosecond and full femtosecond surgery in principle. Its laser ablation directly starts from the corneal epithelial layer. Because the epithelial layer is renewable, the epithelial layer can be recovered after surgery, and there is no trace on the corneal surface after surgery, which also saves the cornea
4. ICL lens implantation: it belongs to intraocular surgery, which does not need to ablate the cornea or change the corneal tissue structure. A small incision of about 2mm is made on the cornea, and the intraocular lens with degree is implanted into the posterior chamber of the eye from the incision. The characteristics of this kind of surgery are reversible and controllable
there are suitable people for each operation, so it is necessary to check before operation and choose the appropriate operation method.

8. Femtosecond laser gives you a better choice. It initially served the U.S. military, passed a large number of evaluation tests, and was certified by NASA in 2007. It is currently the only myopia surgery equipment approved for use in astronauts. It is understood that in the United States, soldiers, pilots, navy and snipers all use femtosecond laser technology to improve their eyesight in order to better complete the task
in addition, femtosecond laser can flexibly set the operation parameters according to indivial differences, such as the thickness and diameter of the corneal flap, which can be customized, and the "whole process scaleless" flap making is more uniform, safer and faster for nerve repair. Therefore, in the slit lamp examination, we can see that the corneal flap surface of each eye is smooth, uniform, very perfect, almost close to the original state of the cornea.

9. Myopia surgery has indications, not everyone can do myopia surgery. Preoperative ophthalmic hospital will carry out a detailed safety check on patients, and some hospitals even have to do 66 safety checks. Only those who have passed the safety check can have myopia surgery. This is one of the reasons why although some doctors are short-sighted, they still don't do surgery
surgical conditions: clear demand for removal of the lens; Over 18 years old, the diopter is stable in the past two years, and the development rate is not more than 50 degrees per year; Corneal thickness is not less than 450 μ m. The diopter is no more than 1200 degrees for myopia, 600 degrees for hyperopia and 600 degrees for astigmatism; For those who wear contact lenses, soft lenses should be stopped for one week and hard lenses should be stopped for more than two weeks; There was no active ophthalmopathy; Have a complete and detailed understanding of the advantages and disadvantages of the operation, and the expectation of the operation results is in line with the reality; There was no autoimmune disease.

10. On the second day after the operation, you can use your eyes, work and study normally. It should be noted that although myopia surgery can correct the body's vision, but after surgery, we should pay attention to develop a better habit of using the eyes, and pay attention to keep the health of the eyes. First of all, we should pay attention to eye hygiene, especially for long-time computer and desk close workers. After using eyes for an hour, we must have a rest. At this time, you can do eye exercises to relax the eyeball, or look into the distance to give your eyes a proper rest. Due to the different operation methods and indivial differences. Therefore, everyone's postoperative recovery period will be different, generally in 3 months to 6 months. No matter the length of the recovery period, it will not affect the normal use of the eyes. As a result, washing face and bathing can be carried out normally.
