Abstract: An electronic enhanced-reality device for low-vision pathologies and an implant procedure to optimise the residual vision of persons with low-vision pathologies, to enhance or recover certain functionalities and autonomy for daily activities, Internet-assisted in cloud mode and which, using patient data along with other data and ophthalmological metadata (big data), plus the adjustment and adaptation of the image captured by a video camera, allows the residual visual of persons affected by low-vision pathologies to be optimised, and operating in such a way that with the optimal parametrisations selected and loaded on to the device, the cameras switch on automatically and their images replace the previous image pre-loaded in the projection area (10). These images are processed by the signal processor (9) and projected by the image projector (31) on to the projection areas (10). These images are the ones which the patient will perceive.
