In A 1st, Scientists Use Revolutionary Gene-Editing Tool To Edit Inside A Patient

For the first time, scientists have used the revolutionary gene-editing technique known as CRISPR to modify genes in cells inside the human body, in the hopes of enabling blind people to see, NPR has learned.

The groundbreaking procedure involved injecting the microscopic gene-editing tool into the eye of a patient blinded by a rare genetic disorder, in hopes of enabling the volunteer to see. They hope to know within weeks whether the approach is working and, if so, to know within two or three months how much vision will be restored.
