This is a groundbreaking initiative which aims to regenerate the eyesight of persons who have lost their sight due to retinal disease by using JIG-SAW’s proprietary wavelength converting software with an algorithm to control the color signals sent to cells.
To begin with, JIG-SAW plans to conduct clinical investigation of the device in conjunction with clinical trials of gene therapeutic agents used to treat diseases such as retinitis pigmentosa (*1).
JIG-SAW aims to combine the technology with gene therapeutic agents to enable those who have lost their eyesight due to a retinal disease to discern scenes and other persons’ faces and to read and write.
