A radical stem cell transplant has significantly improved the blurry vision of three people with severe damage to their cornea.

The clinical trial, which took place in Japan, is the first of its kind in the world, and a significant advancement for stem cell research.

Two years after the operation, no serious safety concerns have come to light, and from the outside looking in, all three corneas look much more transparent than they once did.

Four participants were involved in the study, all of whom suffer from a disorder that causes scar tissue buildup on the cornea, called limbal stem cell deficiency (LSCD).
