Australian stem cell contact lens helps blind people recover

Release date: 2009-06-02


Recently, the research team at the University of New South Wales in Sydney, Australia, successfully used stem cell technology to help repair damaged corneas. Patients do not need to undergo major surgery, not to worry about rejection, just wear special contact lenses and see the light again in a few weeks. Bringing good news to blind people due to corneal lesions.

The researchers invited three men and women with corneal lesions to undergo stem cell therapy tests. The researchers first extracted tiny stem cells from the patient's well-sighted eyes and implanted them on special medical contact lenses. Ten days later, the researchers placed contact lenses covered with stem cells on the patient's damaged eyes. After the stem cells repair the corneal tissue, it takes only 3 weeks to complete the treatment.

It is understood that stem cells are cells that have not yet differentiated and are present in early embryos, bone marrow, umbilical cord, placenta, and some adult cells. They can be cultivated into human tissues and organs such as muscles, bones, and nerves. In recent years, stem cell research has become a hotspot in the field of biomedicine research. Since the 1990s, hematopoietic stem cell transplantation technology has made rapid progress and is safer and more effective. It has become an important means to cure a variety of benign, malignant hematological diseases and hereditary diseases. The disease is still expanding. Shanghai Medical Device Industry Association
