Patent of porcine cornea

The gospel of corneal blindness has come, and domestic artificial cornea will be put into clinical use this year, which gives patients who are silently waiting for living corneal resources the hope of accelerating their sight again. There are about 5 million corneal blind patients in China, and the way for them to see the light again is to wait for the cornea in the resource bank. Many people lost confidence in the long wait. After all, only one in 70 people has access to corneal resources. In view of this scarcity of resources, about five years ago, the world's first 1 biological cornea was born in China, and its principle was taken from the collagen of pig cornea. However, due to various reasons, the promotion of this biological cornea is not very successful, and even many people don't know about it. Five years later, synthetic cornea will meet with you soon. Its main component is collagen from animals, which can better adapt to the human body. The important thing is that you don't have to wait.

The price of this synthetic cornea is 20000 ~ 30000 RMB per piece. In fact, the total cost is similar to transplanting a living model, but compared with foreign synthetic corneas, it is only110 of their price. Foreign artificial cornea technology is very mature, but for various reasons, domestic patients can't enjoy this benefit. Now our domestic medicine is developing rapidly, and our own artificial cornea will also benefit domestic corneal blind patients. Most corneal blindness patients are ordinary people, and their wages are not very high, but the cost of artificial cornea in China is far cheaper than that in foreign countries, which will not cause too much burden on their normal life. And the effect is also gratifying, the average visual acuity can be restored to about 0.5, and the best can even be restored to 1.0.

Many corneal blindness patients are very excited when they learn the good news. They are all looking forward to this year's clinical trial. Although traditional corneal transplantation will also encounter patient rejection or surgical failure. However, some people still think that living cornea is better than artificial cornea, probably because its resources are precious, after all, it is stripped from the human body. However, due to the shortage of resources and the sharp increase in the number of patients, the market for artificial corneas is still good. With the continuous development and progress of this patented technology, it is believed that more and more corneal blind patients will use the most suitable artificial cornea.

It is already the window of the soul, please protect this window. In addition to corneal membrane patients, many people with damaged fundus are also facing the crisis of blindness, instead of staying up late. The cultivation of normal work and rest is also the primary condition for protecting eyes. Please try to live a self-disciplined life.
