Active subretinal implants: Design, functionality, and operational experience

Walter Wrobel
The active subretinal implant has been designed based on MEA measurements with chicken retina samples. Threshold for excitation was determined to be 0.5 to 1 nC, with a dynamic range up to 10 nC/electrode. Achievable spatial resolution was estimated at 0.5°.
