Curing Blindness With Stem Cell Contact Lenses

Curing Blindness With Stem Cell Contact Lenses

Three patients have had their sight restored in less than a month by contact lenses cultured with stem cells. All three patients were blind in one eye. The medical researchers performing the experimental procedure extracted stem cells from their working eyes, cultured them in contact lenses for 10 days, and gave them to the patients. Within 10 to 14 days of use, the stem cells began recolonizing and repairing the cornea.

Of the three patients, two were legally blind but can now read the largest letters on an eye chart, while the third, who could previously read the top few rows of the chart, is now able to pass the vision test for a driver’s license. The scientists doing the study are cautious, still remaining unsure as to whether the correction will remain stable, but the fact that the three test patients have been enjoying restored sight for the last 18 months is encouraging.
