Bionic eyes are emerging! The latest trials of retinal sensor implants have yielded better
results than before – and patient reports of adaptation remind me of descriptions from patients who have to adjust to the new sounds from cochlear implants that restore hearing – hearing, but not as they knew it before. In both cases, you still need a working cranial nerve which is why this technology won’t work for everyone. Of course the current costs are prohibitive, but this is a hugely exciting step forward as the greatest cause of blindness in the over 65s in the West is macular degeneration for which this technology could work. Such would be the demand it would bankrupt the NHS, so I expect the actuaries for the health insurers will be watching carefully!
