Cataracts, a clouding of lenses leading to vision defects, cause more than half of the world’s cases of blindness, but current treatments carry complications and often create the need for corrective lenses post-surgery.

Now a team of researchers from China and the U.S. has developed a technique to remove clouded lenses without removing endogenous stem cells, which then go on to regrow functional lenses and restore vision in human patients.

The findings were published yesterday (March 9 2016) in Nature.

An ultimate goal of stem cell research is to turn on the regenerative potential of one’s own stem cells for tissue and organ repair and disease therapy,” We believe that our new approach will result in a paradigm shift in cataract surgery and may offer patients a safer and better treatment option in the future.”

After initial lab test, it was finally, performed in a group of 12 human infants born with cataracts—the researchers devised a minimally invasive technique to remove lenses while preserving endogenous LECs. Left in place, the team showed, these LECs could regenerate functional lenses. What’s more, compared to a control group of 25 children who received conventional treatment, test group children showed a lower incidence of post-surgery inflammation and lens clouding eight months after the procedure.

Stem cell researcher Dusko Ilic of King’s College London told The Guardian that the study represented “one of the finest achievements in the field of regenerative medicine.”
