Abstract：In recent years，the retinal prosthesis has become a hot point in vision restoration. This paper introduces the main categories and implementation methods of ASIC (application specific integrated circuit) for retinal prosthesis. The comparison of the implementation of epiretinal prosthesis and subretinal prosthesis is made to clarify their advantages as well as disadvantages. The basic theories and research progress of the power and data telemetry module, global digital controller and neural stimulator array are discussed. Challenges and potential trends in the design of ASIC for retinal prosthesis are discussed as well.
