Chinese researchers have successfully developed a robot for ophthalmic surgery.
Chinese researchers have developed an autonomous robotic system that can perform precise injections inside the human eye, improving the accuracy and safety of surgeries for retinal diseases.
A recent study published in the journal "Science Robotics" showed that a surgical robot developed by a team from the Institute of Automation, Chinese Academy of Sciences, successfully performed subretinal and intravascular injections in animal trials, achieving a success rate of 100%.
Ophthalmic surgery, especially surgeries involving the retina, is extremely challenging due to the small size and delicate structure of the retina. This new system uses a series of algorithms to achieve three-dimensional spatial perception, extremely precise positioning, and path control, thereby guiding the movement of the robotic arm.
Experiments conducted using simulated eye models, ex vivo pig eyes, and live animal eyes showed that compared to manual surgery, the autonomous robot significantly reduced the average positioning error by nearly 80%; compared to robot-assisted surgery performed by surgeons, the average positioning error was reduced by nearly 55%.
These results demonstrate the clinical feasibility of autonomous micro-ophthalmic surgical robots and their ability to improve the accuracy, safety, and consistency of injections.
The researchers explained that this automated system can enhance the consistency and safety of the surgical process, reduce the training time for surgeons, and make complex ophthalmic surgeries possible in remote areas or harsh environments where specialized surgeons are lacking.
