No…not yet! There is a lot of research in this field at the moment but nothing that is remotely applicable to people. What will soon be possible is to replace some dead or sick cells with stem cells. Clinical trials are just starting now to see if stem cells can help the layer underneath the retina in patients with age related macular degeneration. It will be many years before this is widely available even if the trials are successful.Artificial (silicone chip) retinal implants are close to being accepted into clinical practice. There are many competing designs for these devices and none of them are able to offer high quality vision. Again, lots of research will mean that progress will be made over time.
