The NBA also has myopia, so why don’t they do eye surgery? Does this mean that laser eye surgery is still immature?

Laser eye surgery in the UK is a "red light"

Domestic ophthalmology experts say: the safety and effectiveness of eye laser refractive surgery can be affirmed

Yesterday, a reporter from the Morning Post learned from the British National Clinical Research Institute: Since there is insufficient evidence to confirm that eye laser refractive surgery is safe enough, the institute has started to conduct inspections on myopia and hyperopia in the National Health Service (NHS) from December 15. Laser surgery lights up the "red light". However, a domestic ophthalmologist said in an interview with a reporter from the Morning Post: Under certain conditions, the safety and effectiveness of eye laser refractive surgery can still be affirmed. From the current point of view, the treatment effect of most domestic patients is still relatively good. .

The surgery lacks long-term safety

As the professional and authoritative health organization in England and Wales, the British National Clinical Research Institute conducted a year-long evaluation of laser eye refractive surgery. Its assessment is that the currently available evidence on the safety of laser surgery for myopia and hyperopia is not sufficient to support the promotion of this type of surgery in the National Health Service.

According to the "Guidance on the Release of Eye Laser Refractive Surgery" report provided by the British National Clinical Research Institute, Morning News reporters found that: although the report acknowledges that existing eye laser refractive surgery is effective for some patients with mild and moderate diseases, It is effective for patients with severe myopia, but the report also states that "there is insufficient evidence that this type of surgery is effective for patients with severe myopia or hyperopia."

At the same time, the British National Clinical Research Institute expressed concerns about the long-term safety of laser surgery for nearsightedness and farsightedness. The report states: "There are concerns about the long-term safety of laser surgery for nearsightedness and hyperopia, and the available evidence is insufficient to support its use without specific consent [from the National Health Service]."

Of course, the British National Clinical Research Institute has not completely banned laser surgery for myopia and hyperopia. The report points out: “If clinicians want to carry out laser refractive surgery, they need to do the following: Let patients fully understand the purpose of the surgery. Risks and provide them with clear enough written information; review and review the clinical results of all laser surgeries; doctors should have sufficient training experience before performing surgery, and their level of training should meet the standards set by the Royal College of Ophthalmologists ."

25% of patients have postoperative night vision problems

"Some patients get worse after undergoing eye laser refractive surgery, and ophthalmologists are also concerned about the effects of laser surgery. We need to know more about the long-term consequences that may still be hidden," said Professor Bruce, who chairs the UK Procedures Advisory Committee. "Laser surgery improves the vision of near- and far-sighted patients to a certain extent, but this can also be improved by wearing glasses and contact lenses. Whether laser surgery is safe is still worthy of attention. Many people have undergone surgery, but they have no overall understanding of the situation. The complexity of the procedure and its possible outcomes are poorly understood, which is why the UK National Institute of Clinical Research is so concerned about laser surgery." According to statistics, at least 100,000 people in the UK spend between 2,000 and 2,000 pounds each year. ￡3,000 for laser eye refractive surgery. Some companies market their eye surgeries with extensive publicity about their effectiveness and safety. The clinical results of some hospitals even stated that the probability of complications caused by this kind of surgery is less than 1%, while other hospitals did not mention the side effects of the surgery at all in their publicity.

According to 2003 statistics from the Medical Defense Alliance, the UK's largest doctors' medical malpractice insurance group, the number of litigation cases caused by eye laser refractive surgery in the UK has increased by 16% in the past six years. These litigation disputes account for one-third of all ophthalmology medical litigation cases filed by the Medical Defense Alliance. A survey conducted by the British Consumers Association shows that due to these problems in the medical industry, 25% of patients will have their night vision affected after surgery, especially when driving. Some patients will also develop serious complications after surgery. .

This type of surgery is increasing year by year

According to Dr. Zhou Xingtao from the Optometry Center of Fudan University Eye, Ear, Nose and Throat Hospital, the number of patients undergoing laser refractive surgery in China is increasing year by year. "There were about 450,000 people in 2002 and about 550,000 people in 2003. This year's data has not yet been finalized, but it is certain that there will be more than 10,000 cases in Shanghai this year."

For the British National Clinical Research Institute The report mentioned that "there is insufficient evidence to show that this type of surgery is effective for patients with severe myopia or hyperopia." Dr. Zhou Xingtao expressed a certain degree of agreement. "We rarely perform laser correction surgery for hyperopia, because the effect is not as significant as laser correction surgery for myopia, and it is not very stable; for myopia above 1,200 degrees, we will be more cautious, because the deeper the degree, the more limited the correction effect, and the side effects The response has also increased accordingly, and the choice of surgical method needs to be considered more."

"This report makes us pay more attention to laser refractive surgery, especially the postoperative visual quality. , the safety and effectiveness of laser refractive surgery can be affirmed. One of the important prerequisites is that the doctor chooses the correct surgical plan for the patient, which also includes the doctor's excellent skills and good equipment.

"Dr. Zhou Xingtao admitted that laser surgery, like any other surgery, also has certain surgical risks. "Failed surgery may indeed cause eye inflammation, unsmooth corneal incision, or changes in the diopter of the eye. ”
