Seoul Artificial Retina Project started research in the year 2000, and tried preclinical experiments of subretinal, epiretinal and suprachoroidal stimulation. In this presentation, overview of the Korean artificial retina project will be introduced. Polyimide and liquid crystal polymer (LCP)-based gold electrodes were fabricated and tested in suprachoroidial, subretinal, and epiretinal conditions in rabbit eyes, and LCP was chosen as a base material for the artificial retina system. Monolithic, one-package system was designed and functionally tested ex vivo. In vivo experiments were done and the design of the package was revised. High-density electrode arrays are under investigation and stimulation parameters are being optimized by ex vivo experiments with multichannel electrode array recording.
