Scientists create 'living lens' from stem cells to treat blindness

A team of researchers have created a working ‘living lens’ that could work towards restoring the sight of the blind; repairing damaged retinas and more.

In the future, having to live with blindness might not be the only way to effectively manage the condition; a team of researches from Osaka University and Cardiff University have manufactured a living lens that could aid in repair operations.
Their findings, described in the journal Nature, detail that the living tissue both teams created from stem cells could be used to repair damage lenses, retinas and corneas, and could potentially restore the power of sight.

The researchers made use of human stem cells that would generate different types of eye cells, and grew and then transplanted working tissue into rabbits that had vision-imparing conditions. The rabbits who underwent the procedure can now see fully once again.
The research takes direction from another study, in which Chinese and American scientists treated 12 human toddlers suffering from cataracts by transplanting lenses grown from stem cells.
The results of Osaka University and Cardiff University’s study have revealed that stem cells could theoretically be used to create any kind of eye cell.

Unfortunately, the technology won’t be available to adult patients at any point in the near future, but the results of the study hold promise for those suffering from vision-impairing conditions.
