A recent article by Dr. Radhika Natarajan highlights an emerging electronic vision platform that could offer future therapeutic possibilities for patients with terminal corneal blindness. The proposed “Virtual ViSN” system utilizes a spectacle-mounted camera to capture external images and wirelessly transmit them across opaque corneas using radiofrequency waves.
An intraocular microcontroller chip and mini projector then reconstruct and project the image directly onto the retina, bypassing the diseased anterior segment. The concept draws inspiration from retinal prosthetic systems such as Argus II and may provide an alternative in severe ocular surface disorders where conventional corneal transplantation and keratoprosthesis procedures have limited success. Wireless transmission may also help reduce complications associated with cable-based systems, including infection and device…
