From the article: Sabater, director of the Corneal Innovation Lab at the eye institute, said gene therapy eyedrops could potentially be used for other diseases by changing the gene delivered by the virus. For example, a different gene could be used to treat Fuchs’ dystrophy, which affects 18 million people in the U.S. and accounts for about half the nation’s corneal transplants.
