For nearly 100 million people worldwide, cataracts steal sight not because medicine lacks a remedy, but because the remedy cannot reach them. In five towns near Pondicherry, India, researchers asked whether a £150 smartphone attachment and three hours of training might bridge that distance — and found that remote ophthalmologists reviewing images agreed with in-person doctors 96% of the time. The study, presented at a major European ophthalmology congress, suggests that the ancient problem of geography need not be the final word on preventable blindness.
