Robot Injects Drugs into Back of Eyeball More Accurately Than Surgeons
“You have to insert a needle into a blood vessel that’s the size of human hair, and the needle itself is even smaller than that,” says Ji Woong Kim at Johns Hopkins University in Maryland.

The Steady Hand Eye Robot (SHER) can inject drugs into the back of the eyeball faster and more accurately than surgeons to treat retinal vein occlusion, according to Johns Hopkins University researcher
An artificial intelligence trained on video of human surgeons controls SHER, which inserts a 15-micrometer-wide needle into a vein through a small incision in the sclera.
Two dozen experiments on pig eyes proved the robot could surpass human surgeons' ability by targeting veins with 22-micrometer accuracy in less than 35 seconds, consistently penetrating the vein without incurring damage.
