Yesterday (30), Morning News reporter learned from the National Institute of Clinical Research: In the absence of sufficient evidence to confirm eye laser refraction surgery safe enough, the Institute has from December 15 on the National Health Service (NHS ) In the near-far-eye laser surgery lights up the "red light." However, there are ophthalmologists in the Morning News reporter interview said: Under certain conditions, the safety and effectiveness of refractive laser eye surgery is still certain, from the current point of view, the treatment effect of most patients is still relatively good.
Surgery lacks long-term safety
As a leading authoritative health organization in England and Wales, the National Institute of Clinical Research conducted a one-year assessment of ocular laser refractive surgery. The result of its assessment is that from the current evidence available on the safety of laser surgery in near and far eyes, it is not enough to support the promotion of such surgery in the national medical service system.
According to the report issued by the National Institute of Clinical Research on Ocular Laser Refractive Surgery, the Morning Post reporter found that although the report acknowledges that existing ocular laser refractive surgery is effective for some patients with mild to moderate myopia , But the report also pointed out that "there is not enough evidence that such surgery is effective in patients with severe myopia or hyperopia."
Meanwhile, the National Institute of Clinical Research in the UK expressed concern about the long-term safety of near-far laser surgery. The report said: "There are concerns about the long-term safety of near-far laser surgery, which is not supported by the lack of specific agreement with the National Medical Services."
Of course, the National Institute of Clinical Research has not completely banned myopia laser surgery, the report said: "If clinicians want to carry out eye laser refractive surgery, you need to do the following: Patients fully recognized the risk of surgery Sex, and provide them with written information that is clear enough; review and review all clinical outcomes of laser surgery; and adequate medical training prior to surgery by a physician, meeting the levels established by the Royal Academy of Ophthalmology. "
25% of patients after surgery affect night vision
"Some patients get worse after receiving ocular laser refractive surgery and ophthalmologists are also focused on the long-term results of laser surgery, and we need to know more about what may be hidden." Professor Bruce, chairman of the UK's Program Advisor Board, said . Laser surgery to a certain extent, improve the vision of patients with near vision, but this can also be worn by wearing glasses and contact lenses to improve the safety of laser surgery is still very noteworthy.Many people underwent surgery, but for the whole Little is known about the complexity of surgery and the likely outcome, which is why the National Institute of Clinical Research of the United Kingdom is so concerned with laser surgery. "
According to statistics, at least 100,000 people in the UK spend 2000 to 3000 pounds per day for ocular laser refractive surgery. A number of companies have conducted extensive publicity on their effectiveness and safety in order to market their eye surgeries. The clinical results of some hospitals even claim that the probability of such an operation leading to complications is less than 1%, while other hospitals make no mention of the side effects of surgery in publicity.
According to the 2003 medical malpractice insurance group Medical Defense Coalition, Britain's largest medical association, the number of litigation cases caused by eye laser refractive surgery in the United Kingdom increased by 16% over the past six years. These litigation disputes were held in the Department of Ophthalmology Medical litigation cases, accounting for one third. A survey conducted by the Consumers Association of the United Kingdom shows that night vision may be affected in 25% of patients due to these problems in the medical industry, especially when driving, and some patients may experience severe complications after surgery .
Such surgery showed a trend of increasing year by year
According to Dr. Zhou Xingtao, director of Optometry Center of Otolaryngology Hospital affiliated to Fudan University, the number of patients undergoing refractive laser surgery in China has been increasing year by year. "About 450,000 people were in 2002 and about 550,000 in 2003. There is no final statistics for this year. Come out, but what is certain is that there are 10,000 cases in Shanghai this year. "
As for the report of the National Institute of Clinical Research in the UK, "there is not enough evidence to show that such surgery is effective in patients with severe myopia or hyperopia," Dr. Zhou Xingtao expressed some degree of approval. "We rarely do hyperopia laser correction surgery, because the effect is not as good as myopia laser surgery, but also not very stable; for more than 1200 degrees of myopia, we will be more cautious, because the degree is more, the more limited the effect of correction, vice The response is also a corresponding increase in the choice of surgical methods more need to be considered.
"This report gives us more attention to laser refractive surgery, especially postoperative visual quality.Of course, the safety and effectiveness of laser refractive surgery so far are certain, and one of the important prerequisites is that , The doctor has chosen the right surgical solution for the patient, and also includes the doctor's excellent technique and good preparation etc. "Dr Zhou Xingtao frankly stated that laser surgery has the same surgical risk as any other operation." It is indeed possible that the failed operation Causes inflammation of the eye, corneal incision does not go well, or changes in eye refraction.
