BEIJING: Doctors of Shandong Eye Institute in China, on Monday, declared  the successful operation of a bio-engineered pig cornea into a human eye.

“The patient’s vision has gradually improved after a three month recovery period, which means the transplant was a success,” said Zhai Hualei, director of Shandong Eye Institute’s cornea division.

Wang Xinyi, 60, was suffering  from  corneal ulcer. He could only see moving objects within 10 cm.

“The doctors originally told me that my father might lose sight in one eye because there are not enough cornea donations,” Wang’s son said.

The transplant used a bio-engineered cornea named Acornea, the first such product to be licensed by the China Food and Drug Administration in April.

“With the pig cornea as the main material, the product is devoid of cells, hybrid proteins, and other antigens. It retains a natural collagen structure with remarkable bio-compatibility and biological safety,” said Zhai.

Cornea diseases are one of the biggest causes of blindness in China. New cases are increasing by 100,000 each year, however, only about 5,000 people receive a cornea transplant annually.

Beijing Tongren Hospital and Wuhan Xiehe Hospital, among others, have been conducting clinical trials of Acornea since 2010, recording a success rate of 94.44 percent, similar to the results seen with donated human corneas.(IANS),(Image: the-newshub.com)

The PMI of China’s manufacturing activity was released on Sunday. It stood at 51.6 points in December, down from 51.8 in November, Efe news quoted the figures released by the National Bureau of Statistics (NBS) as saying.

 In contrast, the service sector activity grew to stand at 55 points in December as compared to 54.8 in November.

A figure above 50 points suggests expansion while a figure lower than 50 indicates contraction. The service sector already accounts for more than half of China’s gross domestic product.

The December figure for the manufacturing index was at par with the annual average, which points to strong resilience in China’s growth, according to NBS statistician Zhao Qinghe. IANS
