Chinese researchers succeed in developing a robot for eye surgery.

A team of Chinese researchers has developed an autonomous robotic system capable of performing precise injections inside the human eye, improving the accuracy and safety of surgical procedures used to treat retinal diseases.

The surgical robot, developed by a team from the Institute of Automation at the Chinese Academy of Sciences, successfully performed subretinal and intravascular injections in animal trials with a 100% success rate, according to a study recently published in the journal Science Robotics.

Eye surgery, especially that involving the retina, is extremely difficult due to its small size and delicate structure. The new system uses a set of algorithms for three-dimensional spatial perception, extremely precise positioning, and path control to guide a robotic arm.

Experiments using simulated eye models, an ex vivo pig eye, and an in vivo animal eye showed that the autonomous robot significantly reduced average positioning errors by nearly 80% compared to manual surgery, and by nearly 55% compared to robotic surgery performed by a surgeon, according to the study.

These results demonstrate the clinical feasibility of the autonomous microsurgical eye robot, and its ability to improve injection accuracy, safety and consistency.

The researchers explained that such an automated system could enhance the consistency and safety of surgical procedures, reduce the training time for surgeons, and enable complex eye surgeries to be performed in remote areas or harsh environments where specialized surgeons are not available.
