US 2020/0138563 A1 · RETINA REGENERATION WITH A TISSUE-AND-TECHNOLOGY PROSTHESIS

Abstract

An embodiment in accordance with the present invention includes 3D retinal tissue generated in a laboratory. The 3D retinal tissue is coupled to an engineered microelectronic chip. The 3D retinal tissue together with the engineered microelectronic chip enable retinal regeneration and vision restoration for patients with retinal cell damage. The engineered microelectronic chip sends electrical signals to specific parts of the 3D retinal tissue for stimulating and recording both the 3D retinal tissue and the cells in the patient's own retina. The chip may be absorbable or removable once connection is made between the 3D retinal tissue and the patient's own remaining retinal tissue.
