World's First Implantable Stimulator for Congenital Nystagmus Implanted and Activated in First Patient
Start here
An implantable muscle-nerve electrical stimulator for congenital nystagmus, developed by Wang Lejin's team at Peking University People's Hospital, has completed its first patient implantation and activation since receiving regulatory approval. The device was approved on March 13, 2026 through the NMPA's green channel for Class III innovative medical devices, and it is the first of its kind worldwide. Clinical evidence supporting the approval came from 10 feasibility and 61 confirmatory trial subjects, in whom foveation time increased several-fold, nystagmus amplitude and frequency fell markedly, and both visual quality and quality of life improved. Broader clinical rollout and longer-term outcomes beyond the trial population remain open questions.
