According to the British National Clinical Research Institute, because there is not enough evidence to prove that eye laser refractive surgery is safe enough, the institute has turned on the "red light" of laser surgery for myopia and hyperopia in the National Health Service (NHS).
Lack of long-term safety in surgery:
As a professional and authoritative health institution in England and Wales, the National Clinical Research Institute of the United Kingdom conducted a one-year evaluation of eye laser refractive surgery. The evaluation results show that the evidence of the safety of near-vision and far-vision laser surgery is not enough to support the promotion of this kind of surgery in the national medical service system.
According to the report "Guidelines for Releasing Eye Laser Refractive Surgery" provided by the National Clinical Research Institute of the United Kingdom, although the existing eye laser refractive surgery has a corrective effect on some patients with mild and moderate myopia, the report also points out that "there is not enough evidence to show that this surgery is effective for patients with severe myopia or hyperopia".
At the same time, the National Clinical Research Institute of the United Kingdom expressed concern about the long-term safety of laser surgery for myopia and hyperopia. The report pointed out: "People are worried about the long-term safety of near-distance laser surgery, and the existing evidence is not enough to support this kind of surgery without the special consent of the national medical service system."
25% patients' night vision function was affected after operation:
"Some patients have deteriorated after undergoing eye laser refractive surgery, and ophthalmologists are also concerned about the long-term results of laser surgery. We need to know more about the problems that may still be hidden. " Professor Bruce, chairman of the British project advisory Committee, said. "Laser surgery has improved the vision of patients with myopia and hyperopia to some extent, but it can also be improved by wearing glasses and contact lenses. Whether laser surgery is safe or not is still worthy of attention. Many people have had surgery, but little is known about the complexity and possible outcome of the whole operation. This is why the British National Clinical Research Institute is so concerned about laser surgery. "
According to statistics, at least 654.38 million people in Britain spend 2,000 to 3,000 pounds on eye laser refractive surgery every year. In order to promote their eye surgery, some companies have made a lot of publicity about its effect and safety. The clinical results of some hospitals even claim that the probability of complications caused by this operation is less than 1%, while other hospitals even don't mention the side effects of the operation in their propaganda.
According to the statistics of Medical Defense Alliance, the largest medical malpractice insurance group in Britain in 2003, the number of lawsuits caused by eye laser refractive surgery in Britain has increased by 16% in the past six years. These litigation disputes account for one-third of all ophthalmic medical litigation cases of the medical defense alliance. According to the survey of British Consumers Association, due to these problems in the medical industry, 25% of patients' night vision will be affected after operation, especially when driving, and some patients will have serious complications after operation.
This report makes us pay more attention to laser refractive surgery, especially the postoperative visual quality. Failure in surgery may indeed cause eye inflammation, obstructed corneal incision, or changes in eye diopter.

Laser refractive surgery is to remove a part of cornea with laser, thus changing diopter. This operation was introduced into China from 1993. It is understood that this kind of therapeutic surgery requires higher physical fitness of machines, doctors and patients./kloc-teenagers under 0/8 years of age, people with systemic diseases such as infectious inflammation, glaucoma, cataract, or diabetes and collagen diseases are not suitable for this kind of surgical treatment.
Answers to common questions of myopia patients undergoing laser surgery
2005-09-0 1
Q: Am I suitable for laser surgery?
Answer: to successfully undergo laser refractive surgery, the following conditions should be met: age 18 ~ 50 years old; The refractive power is stable, and it is deepened by no more than 50 degrees every year; No active eye lesions; No diabetes and collagen diseases; Voluntary surgery.
Q: Can both eyes do it?
A: Of course.
Q: When can I continue to work?
A: Most patients are within 1-2 days.
Q: How long will the effect of LASIK last?
A: As long as your refractive index is stable, the effect of the operation will last for a long time and will hardly fade. Due to the needs of employment and school, a few patients have surgery when their eyesight is not completely stable, and may develop myopia in the future.
Q: Does LASIK hurt?
A: There is almost no pain. Before the operation, the doctor will drop some eye drops on your eyes to play the role of surface anesthesia. Some people will feel slight edema when making corneal flap during surgery, and you will feel transient blurred vision at this time. A few patients will have foreign body sensation, tears and other uncomfortable feelings in the early postoperative period, which will disappear naturally after 3~4 hours without medication.
Q: Can the postoperative visual acuity reach 1.0?
A: Although the surgical effect is excellent, your surgical result depends on many factors, such as your best corrected vision before operation, your own reaction to laser treatment and your own recovery.
Q: What's the difference between PRK and LASIK?
A: Both of them use excimer laser to reshape cornea to correct myopia, hyperopia and astigmatism. The difference is that PRK cuts corneal epithelium directly, while LASIK makes corneal flap before laser. The two methods have the same long-term effect on moderate and low myopia (below 400 degrees). For high myopia (above 500 degrees), LASIK has a good long-term effect. Moreover, compared with PRK, LASIK has no obvious pain, faster vision recovery and fewer complications. Yetiantian
Armed police general hospital-laser myopia treatment center
The Armed Police General Hospital is a third-class first-class hospital. In 200 1 year, it was selected by the Chinese Medical Association as the first batch of "hospitals where people can see clearly and feel at ease" in China, and it was selected for three consecutive years. In 2002, the "Postdoctoral Research Center" was established with the approval of the Ministry of Personnel; Now it is the Fourth Military Medical University, the Teaching Hospital of the Academy of Military Medical Sciences, and the Beijing Medical Insurance Designated Hospital.
Excimer laser therapy for myopia is a newly established high-tech medical project in the Armed Police General Hospital. Relying on the outstanding academic advantages and expert team of the Eye General Hospital, the center uses modern diagnosis and treatment technology and advanced equipment to treat patients with myopia, hyperopia and astigmatism. The Eighth Generation Intelligent Small Spot Flying Spot Scanning Laser Treatment System (ESIRIS) newly introduced by the Center is operated by senior experts who have been engaged in excimer laser vision correction surgery for many years. Through excimer laser in situ keratomileusis, ametropia patients can correct their vision, take off their glasses, relieve the life troubles caused by it, and feel beautiful and confident again.
Adhering to the consistent good reputation and medical ethics of military hospitals, our center takes the service tenet of "officers and soldiers are satisfied and the people are at ease" and puts forward the slogan of "making LASIK an affordable civilian operation for everyone", taking the lead in breaking the ice in the price of LASIK surgery in the third-class first-class hospitals in North China, and giving special preferential treatment to soldiers, police, students, teachers and other groups. Cutting-edge medical equipment, experienced experts, warm and thoughtful service, comfortable medical environment, immediate treatment effect, and civilian operation price make the laser myopia treatment center of Armed Police General Hospital in a leading position in the same industry in Beijing, bringing good economic benefits as well as huge social benefits.
In May 2004, in order to strengthen the military-civilian relationship and care for students' health, our center launched a large-scale public welfare activity of "LASIK campus trip" in conjunction with the Youth League Committee and the Red Cross Society of six universities in Beijing. More than a dozen ophthalmologists went deep into the university campus to carry out health consultation like eyes, and invited Professor Lin Shunchao, an honorary professor of the Armed Police General Hospital, a famous ophthalmologist, medical educator and philanthropist in Hong Kong, on June 6th (National Eye Love Day). Free LASIK surgery was provided for 30 poor myopia college students (see the front page report of Beijing Evening News, Jinghua Times, CCTV 2 "The Road to Health" and other media on June 6). After the operation, all the students' naked vision recovered to above 1.0, and some recovered to 1.5, which was good.
With warm and thoughtful service, the center will wholeheartedly serve myopia patients with its superb professional technology and world-class high-tech medical equipment advantages, and bring them a brighter and better tomorrow with high technology.

Correct use of contact lenses. 1. The length of time that can be worn in contact with eyes every day; What should I pay attention to when wearing it?
The time of a day is about 8 hours, and the related clinical precautions for wearing contact lenses.
1, before wearing contact lenses, you need to do a standardized vision examination and eye health examination, so that doctors can check whether it is suitable to wear contact lenses and what kind of contact lenses to wear.
2. According to the optometry degree and the measured corneal curvature, choose the appropriate lens degree and the curvature of the lens base.
3. Contact lens wearers should have absolute compliance and good initiative, should follow the doctor's advice and take the initiative to accept regular review.
4. Contact lenses may sometimes be damaged for some reasons. At this time, when the eyes wear broken lenses, there will be foreign body sensation and even pain and redness. Especially when one eye feels this way, see a doctor as soon as possible.
When eyes are infected, wearing contact lenses will make you feel uncomfortable, such as itching, pain, redness and so on. , or discomfort due to the aggravation of ocular inflammation caused by deposits on the surface of contact lenses. At this time, you should also see a doctor as soon as possible to prevent more serious complications.
Unless you can wear contact lenses at night, you are generally not allowed to sleep with them.
6. It is suggested that the mirror box be disinfected once a week and replaced once every three months.
7. Replace lenses regularly or as soon as possible. The complications caused by contact lenses are mainly caused by lens deposits. Replace the lens as soon as possible, keep the lens clean and reduce the harm of sediment to the eyes.
8. Special circumstances:
Make-up, first go to the mirror and then make-up, first take off the mirror and then remove makeup.
Pregnant women, it is best not to wear contact lenses, endocrine changes, wearing easy to have adverse reactions.
Swimmers are advised not to wear glasses unless the goggles are completely sealed or new contact lenses are replaced after swimming.
When wearing glasses, it is best not to drop other eye drops, especially some colored eye drops, which should be avoided.
Choosing contact lenses should follow the doctor's advice: in order to prevent diseases caused by unsuitable eyes, it is necessary for us to go to the hospital for final confirmation. In addition, regular inspection every three months is also essential. Don't sleep with contact lenses; Because the secretion of tears is reduced during sleep, the lens will stick to the cornea, and if it is forcibly taken out, it will hurt the cornea (if it is a week-throwing type). So, don't be lazy and take off your contact lenses before going to bed. Keep contact lenses clean: If the care of contact lenses is neglected, bacteria will multiply and even lead to blindness. There are many contact lens care products on the market now, and you can choose to use them according to your own different situations. Such as: no rubbing function, automatic protein removal, and so on.
