После лазерной хирургии MCT контактных линз/High end MCT технологии/Надувная складная лодка/контактные линзы

Product Overview

Description

MCT technology is the leading blindness prevention and treatment technology which is developed by Shanghai Furen Ophthalmology Research Institution and Web Optometry Research Institution after over 10 years´ clinical practice and research. The technology covers the newest achievements of ophthalmology, optometry and Chinese medicine, and is the combination of these three disciplines. MCT technology can effectively correct all kinds of refractive errors, such as children and teenagers myopia, especially the diagnosis and control of pathological myopia, and the prevention of serious complications; the treatment of child and adult amblyopia; the prevention and control of complications caused by high myopia with high IOP; the diagnosis and control of sub clinical keratoconus; correction of hyperopia, high astigmatism and irregular astigmatism, etc. MCT technology based on corneal holographic digital fine designed lens of individuals, and provides the physical model to cornea. This technology is also a programmed process in which corneal shape gradually been deformed into a more reasonable form. Easy to use,efficiency and security.

 

 

 

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 19th 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 expansionof 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 200 degrees a year, and after wearing MCT lens, it will only develop 25 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!
