Natural cure: Scientists create stem cell contact lens

Researchers have found a better and a cheaper way to restore human sight by implanting a contact lens containing stem cells that will repair the human cornea.

Scientists from the University of Sheffield hope that the biodegradable implant disc's stem cells will multiply in the eye, thus rebuilding the transparent layer on the front of the eye, known as the cornea, the degradation of which is one of the major causes of blindness in the world, a study published in Acta Biomaterialia journal revealed.

Since stem cells have the ability to renew themselves through mitotic cell division and differentiation into a diverse range of specialized cell types, scientists hope that it will allow the eye to heal naturally as new implants are designed to form thin membranes by grafting the cells onto the eye itself.

Traditional treatment for cornea damage includes transplanting stem cells into the eye using donated human membranes. But in some cases this procedure fails, as in time the repaired eyes lose the retention of these stem cells, which are required to carry out repairs of the cornea.
