At the moment, folks with broken or diseased corneas are normally handled with tissue from deceased donors, however the ready checklist for these tissues is lengthy in Japan.

Japan has been within the vanguard with regard to the approval of the scientific use of iPS cells, found by stem cell biologist Shinya Yamanaka of Kyoto College, who received the Nobel Prize for his work. Japanese medical doctors have additionally used iPS cells to deal with spinal twine harm, Parkinson's illness and one other eye illness.

The Japanese Ministry of Well being has given Nishida permission to attempt the process on 4 folks. He plans the following operation later this 12 months and hopes to have the process on the clinic in 5 years.
