If the vision decrease after laser surgery,must consider the possibility of pathological myopia

The expansion of myopic population is great in the end of the *9th century and the beginning of new century. At this stage, the frame glasses market rapidly expanded, the optical shop in street started popping up into people's field of vision, and this is because of the concentrated growth of myopic population.

The craze of glasses is from the expanding of myopic population, and of course, also the domestic economic situation. On one hand, because the cost of myopic treatment technology is very high, it can not be popularized; on the other hand, because the development of correction technology is not as fast as the expansion of myopic population, few people will think about the correction of myopia. Because frame Glasses is cheap, simple and can help patients restore vision, it wins the favor of myopia patients.

But changeable in prosperity and decline capricious in rise and fall, now, although the crowd of myopia is still expanding, but the craze of frame glasses is already cooling, economic development makes people rich, and they hope there is a kind of technology which can correct myopia. What people want to do is not only the restoration of good vision, but also the farewell to bad vision. Then, laser Surgery and corneal reshaping technology which could keep up with the times appeared.

The growth of laser surgery is not an accident. It can satisfy myopes who are not willing to wear frame glasses but also with good vision. And for some problems which frame glasses cannot solve, it can also play a role in a certain extent. Laser surgery has developed from RPK, LASIK, and LASEK to today's femtosecond laser. Now people can accept its expenses, and its safety is also rising. Laser surgery not only eases enlargement problem of myopia, but also bring bad vision patients a new choice.

Technology is in progress, and also does the disease. They became more and more complex. Take myopia as example, the occurrence of high myopia was very less before, but now it is relatively common. Laser surgery can correct a certain degree of high myopia and help part of patient restore vision, but it can't actually control pathological myopia. This is the limitation of laser surgery.

Generally, pathological myopia is also called progressive high myopia. The different between it and simple myopia is: the development of simple high myopia will cease when reach a certain degree, while pathological myopia will unlimited develop until patient lose their vision or get blind. In normal circumstance, pathological myopia often will be treated as simple high myopia, and also will be regarded as low myopia in the initial period of development. People with moderate or high myopia are the main crowd of laser surgery, and then there will be a problem. Some people will be with relatively stable visual acuity which meets the expected effect after laser surgery, but for some patients, after laser surgery, over a period of time, their vision will back to the former level, and myopia degree continues to grow. So why?

We began with the principle of laser surgery. It is a kind of cold laser which can cut the corneal surface, make its radian decrease, then reduce the refractive power and finally bring good vision. But there are two reasons of the formation of myopia. Refractive error is just one aspect, and there is another aspect: the excessive extension of the eye axis. This is also the main reason for the formation of myopia. So from myopia pathogenesis, laser surgery can not fundamentally control the development of myopia.

"If a patient did laser surgery which was successful, and their eyesight also return to normal level without redraw for a long time, that patient mostly is with simple myopia (including simple high myopia); but if a patient did laser surgery which was very successful, but after half a year, the bad vision was back, and continued to develop, then we should consider if what they get is pathological myopia." this is the understanding of the original designer of MCT technology, Professor Wang. Now he has been engaged in the prevention of blindness for over twenty years, and his original MCT technology bring many myopes the Gospel.

Professor Wang also said, the vision decreasing after surgery is also related with the operation itself. Insufficient preoperative optometry, incorrect calculation, and not-timely review, all of them may be the cause of the vision back. If the operation was no problem, but the vision decreased, then we could determine if what patient got is pathological myopia. And these patients are better to do fundus photography to observe the changes every year, and also get diagnosis as early as possible, and then take measures to control.

Why will the vision of patients who are with pathological myopia decrease after laser surgery? The reason is the pathogenesis of myopia: the excessive growth of eye axis. For simple myopia patients, the development will cease after reaching a certain degree, the possibility of continuous growth of the eye axis is very small, and the increase will be very slight, so if we solved refractive error, we can basically solve bad eyesight. But pathological myopia is different. The reason why it can unlimited develop is mainly because the eye axis will keep growth, and this increase is far outweigh the simple myopia after laser surgery. So for pathological myopia, the laser surgery can just solve the problem of ametropia, and restore vision temporarily, but eyesight will still return to preoperative levels, and degrees will continue to deepen.

Pathological myopia will unlimitedly develop, and the key is to control this development. In present, there is no medical technology can completely prevent pathological myopia development, and the best way is to control the speed of development. If the development is slow down, the bright of patient will be kept for a longer time. And in the filed of the slowing of pathological myopia development, MCT technology is in the leading place in the world.

What is its representation? Firstly, MCT technology controls the development of degree in the aspect of myopia pathogenesis. Through the directly power from palpebra superior, it stops the increase of eye axis, revises the radian of cornea, avoids the forward protruding of cornea, makes it more flat and finally reduces the degree of myopia.

It is the best method for pathological myopia patients, because it can help them restore vision, and control the development of degree in a certain extend. And how effective it is? For example, if the degree of a pathological myopia patient increases **0 degrees a year, and after wearing MCT lens, it will only develop *5 degrees a year. In this way, its development speed will slow down considerably, and the chance of serious eye complications is also greatly reduced and then directly extended the more bright time.

So, if eye problems of patients who did laser surgery are back, be careful. We should consider the possibility of the pathological myopia, and take effective measures to diagnose and control it. Only this can help them keep their bright and ensure the safety of the eyes. Of course, the leading MCT technology can be your trustworthy choice!

Safety and Effect, the Benchmark of Non-operative Vision Problems Treatment

People live in the world, can not avoid diseases. When the ancient time, doctor became a kind of careers, it has been burdening the duties and responsibilities of healing the wounded and rescuing the dying. Some diseases can be cured by medicine, but some need operation. This is the rule of being a doctor.

Operation is not the original method of Western medicine. Actually, Hua Tuo in the end of the Eastern Han Dynasty was the model of Chinese doctors who are proficient in operation. In today, diseases become more and more complex and operation now is the most important treatment, for example, cardiovascular surgery and cranial nerve surgery and some other common diseases. But we must realize the fact that the operation is not omnipotent, and you can not do operation just as you want, because there are some risks.

In daily life, we will find that only patients with serious illness must take operations or some one who need to do surgical operation. As a doctor, in fact, they are not willing to do operation for patients, because no one can guarantee that the operation will be successful, and once accidents happen, the consequences will be unforeseen. So, operation is the last method we will choose.

Take ophthalmology for example, cataract surgery and corneal transplantation surgery are necessary, because if patients don't to do the operation, they will face to blindness, but if do operation, there will be a ray of hope. Meanwhile, under the request of many patients with poor vision, we also developed laser surgery which can recover normal eyesight, such as RPK, LASIK, and femtosecond laser.

To a certain extent, laser surgery eases the condition of blindness patients who can get the bigger opportunity to see again. This is very good, but on the other hand, myopic patient also rushed to do laser surgery and hope that the surgery can let their own vision "icing on the cake". This inevitably increased the risks of the operation, although the safety of laser surgery is continuously improved.

Have a surgery and have a risk. This can not be changed. So the question, do or not to do, what kind of attitude shall doctors and patients hold?

An oculist had done the operation of myopia for many years, but now he reduces the operation quantity, and starts a new non-operative method to correct bad eyesight. This is a true story, and this doctor is professor Wang in Shanghai Furen Ophthalmology Institution and Web Optometry Institution. It is a turning in the career of him. As a famous doctor, he told us about his feeling of the implementation of eye surgery.

"I did myopic surgery for many years, and I am with a very high success rate. But why I insist on non-operative method? Actually, because of the safety and psychological pressure" Professor Wang said and then he was already the original designers of MCT technology and he has practiced the non-operative method to correct bad eyesight successfully for more than ten years.

There are many myopic patients whose eyes are intact, and the reason why they want to do the operation is to pick off frame glasses, throw away the troubles brought by frame glasses in life. The pressure is very big when doing operation in a good eye, because once there is an accident, it will ruin the light in a man's life. Facing to this big responsibility, before each operation, the doctor must indicate himself that he must do a good job, and in his mind, it is very nervous. After finished an operation, it just like going through a war, and need a long time to recover and adjust. This is the personal experience of Professor Wang when giving patients surgery.

Through the years, two doctors in four who did surgery with Professor Wang were died because of cancer. What the operation brings to doctors are the invisible physical and mental influences. Under the pressure of great responsibility, they are more easy to get sick than normal people. Professor Wang also said, now the doctor-patient relationship is nervous today, in fact, the doctor also have their dumb anguish, and people need to understand doctors, especially the surgeon.

Now, Professor Wang occasionally will do surgery for patients, but he has his own standard, that is "surgery is the only way, and without surgery, patients cannot see object normally ". This is because that the safety and health of patients’ eyes are above everything.

Choose surgery is to choose good vision, but also the selection of risk. Choosing or don't choosing depends on the patient's risk resistance capacity. Patients need to start from their own strengths.

"If poor vision patients choose surgery, only because surgery can achieve the purpose of picking off frame glasses but with the effect of restoring vision and then non-operative method can also do that." This is what Professor Wang often said after creating non-operative MCT technology. And if pathological myopia patients do the surgery, the condition will be hided by the operation, the development of degree and complications can not be controlled. For the eye itself, in some extent, surgery will reduce the structure strength of eyeball, and make the eye disease resistance weakened. For non-operative MCT technology, all above are not problems any longer.

The principle of Laser surgery is flushing cornea through the cold laser, making the corneal surface more smooth and pliable, reducing the refractive power of eyeball, and finally restoring good eyesight. The non-operative MCT technology helps patients restore vision by the night wearing Ortho-k lens. Through the directly power from upper eyelid, it stops the increase of eye axis, revises the radian of cornea, avoids the forward protruding of cornea, makes it more flat and finally reduces the degree of myopia. Moreover, after ophthalmology research, we found that the occurrence of myopia is caused by the excessive extension of eye axis, and from this aspect, MCT technology can control the development of myopia in pathogenesis.

In addition, non-operative MCT technology can make patients' vision reach 1.0 as better as after surgery. Some high myopic patients who are not suited for surgery can control the development of myopia by MCT technology; Pathologic myopia patients can also slow down the development speed of myopia by MCT technology.

A question, will MCT technology lens affect our daily life? MCT lens is night wearing and will be taken off in morning, but still with good vision in the whole day. And the lens is made by special material with high oxygen permeability. With this kind of lens, cornea still can easily take aerobic respiration.

Both non-operative and operative methods service for patients with poor vision and they just take different ways. And under the condition that the effects of these two method are the same, non-operative one can reduce the risk of bad vision correction, the safety is greatly improved, the health of patients’eyes will be

Actually, in the prevention and treatment of blindness this public welfare, surgical and non-operative methods are born because of the original intention that dedicate bright to patients, and both of them put safety and correctional effect as their post. So although Professor Wang reduced the surgery quantity, but he does not leave the road of the prevention and treatment of blindness and MCT technology created by him is a non-operative choice which can be trusted by bad eyesight patients.
