Scientists have developed a new technology that could help treat blindness and other eye conditions. The technique involves using a type of gene therapy called CRISPR-Cas9 to edit the genes in the eye. This could potentially repair damaged genes and restore vision. The researchers successfully tested the technology on mice, and are hoping to soon move on to clinical trials in humans. This breakthrough holds promise for millions of people suffering from vision problems and could revolutionize the field of ophthalmology.
