Looked shocked, fortunately I did not go to do this surgery. Myopic friends look at it! At present, the incidence of myopia in China is more than 30%, and in secondary school students, its incidence is more than half, while in college students the incidence is as high as 74%! In response to this problem, a treatment for myopia has emerged: LASIK, the most recent and popular treatment for myopia, which has been performed on millions of patients throughout China since the first LASIK surgery was performed in 1997, and which improves vision in a short period of time, attracting thousands of people who desperately want to get rid of their glasses. people who want to get rid of their glasses. However, the vast majority of these people are ignorant of the procedure, and why do so many doctors in many hospital eye centers still wear glasses? Why are they letting go of such a good surgery? It wasn't until a few months ago that I figured out it was a conspiracy! Myopic surgery is the biggest conspiracy in medicine this century!
A friend of mine underwent LASIK surgery in March 2002 at a very famous tertiary hospital with ophthalmology specialties in China. Before the surgery, he passed all the tests at the hospital and the results were normal, and no abnormality was found in his corneal topography, so my friend removed his 850-degree glasses as he wished. However, just a month ago, my friend realized that his vision had regressed significantly and he had a lot of irregular astigmatism. He went to another hospital for examination and was finally diagnosed with cone cornea. The end result of cone cornea is cornea transplantation, and as cornea donors are very tight, my friend is feeling worse than death. My friend is only in her 30s and her husband is waiting to divorce her. And before she had the surgery, I learned that she was operated on at that tertiary hospital and did not express any objection at that time.
As a doctor, I know a little bit about ophthalmology, so I'm going to give my personal opinion on this issue. First of all, the principle of LASIK is to make a flap at 130-160um (1um is 1/1000mm) on the cornea, which is equivalent to a concave lens on the cornea, and by changing the curvature of the corneal stroma, it can achieve the purpose of correcting myopia. However, the corneal stroma cannot be cut without limit, and a certain safe thickness must be retained, which is generally recognized as 410um (there is no conclusive evidence to prove it so far), or the thickness of the corneal stroma must be retained more than 250 , or else cone cornea will occur. And a normal person's corneal thickness is about 500 to 600um between , and every 100 degrees of myopia to reduce, according to the 6.5mm cutting diameter (cutting range) to cut 14um depth, and according to the 6.0 diameter of the cutting, it is every 100 degrees to cut 12 units, in addition, astigmatism and myopia to be cut by the thickness is the same. So, the deeper the degree, the more likely it is to be dangerous. And because 410 is a lower limit, myopia plus astigmatism **** about 600-800 degrees of people usually cut well after the end of this lower limit, it is easy to have problems.
So what is the fatal disadvantage of LASIK? We know that a normal cornea is strong enough to withstand the pressure of intraocular pressure on the cornea. But because LASIK cuts the corneal tissue, the cut corneal tissue can not withstand the pressure of intraocular pressure on the cornea, so the cornea will gradually become sharp, and eventually form a cone cornea, cone cornea, the consequences of the vision is to make the loss of eyesight forever. Some hospitals, in order to make huge profits, do not inform patients of this consequence. In addition, hospitals are wrong in saying that laser surgery does not cause blindness, while cone cornea can be considered as indirectly causing blindness. In addition, some hospitals believe that retaining 410 is the safety floor, so what is the basis for this? If a cornea below 410 produces a conical cornea, who is to say that those whose corneal thickness is on the verge of the lower limit will not develop a conical cornea within 10 years or so as a result of gradual deformation of the cornea? And who is the ophthalmic authority who can come forward and guarantee that those who need to cut more corneal tissue because of high myopia (600 degrees or more) won't have problems in 15 or 20 years?
We know that a medical technology has to go through a period of observation from the time it is invented to the time it is applied to the clinic, and it has only been less than 8 years since LASIK was introduced in China, and the majority of ophthalmologists in China are applying it to a wide range of clinics, knowing full well the dangers of the procedure (which is understandable to anyone who knows a little bit about ophthalmology, not to mention a doctor), but taking the risk of disregarding the world's opinion and not taking the risk. They are aware of the dangers of this procedure (anyone who knows a little about ophthalmology can understand this, not to mention doctors), yet they risk universal condemnation by deceiving patients and treating patients' eyes as experiments, so are you still human? Doctors are called white angels, your duty is to save lives, not to use an immature technology to harm people in order to divide a market! The conical cornea that results from LASIK is now considered a terminal disease and can only be solved with a corneal transplant! Each case of surgery can bring you thousands of dollars of profit, and for the sake of these profits, you even treat the majority of patients as experiments, conceal the risks of surgery, and make the majority of patients risk becoming blind or quasi-blind after a number of years, what peace of mind do you have! You have planted a time bomb in the eyes of millions of people, where is your conscience? Now that the big cities have problems with their tertiary hospitals, how can you guarantee the safety of the surgery in your small hospitals in underdeveloped areas?
Anyone who reads this article and has a conscience, if you think this article makes sense, please forward it to other forums so that more people can understand the truth. If you are not afraid of the fact that you will become blind or quasi-blind in a few years when you are at the peak of your career and the backbone of your family, please be bold enough to become a doctor's experiment.
