Abstract: Visual prostheses are artificial devices employed to revert blindness: a medical condition affecting more than 39 million people worldwide.

In the first part of the talk, I will present the development and validation in-vitro and in-vivo of a wide-field, photovoltaic, and injectable retinal prosthesis. The report will include data obtained both in-vitro with retinal explants and in-vivo with large animal models.

In the second part of the talk, I will introduce a novel visual prosthesis based on intra-neural stimulation of the optic nerve. The OpticSELINE is an intraneural 3D electrode array capable of selectively activating the optic nerve fibres to induce artificial vision. This technology is essential to overcome the exclusion criteria of retinal implants. The results from our in-vivo preclinical trial in large animals will be presented
