Subretinal VS Epiretinal

Subretinal
-All replacements are made within the eye, no external device needed
-Replaces the rods and cones with silicon plate containing light sensitive microphotodiodes attached to an electrode
-light stimulates the microphotodiodes which then sends a message from the electrode to the remaining neural cells

Epiretinal
-Uses an external camera to receive electrical signals
-Electrodes from the implant then stimulate directly stimulate the axons that form on the optic nerve

I think that Epiretinal Implants would work the best, but Subretinal Implants are ideal. I believe Epiretinal implants would work better simply for the reason that less can go wrong and it is easier to repair if something does in fact go wrong. If a subretinal implant malfunctions, to repair it a doctor must go into the eye every time, unlike if a Epiretinal Implant malfunctions. However, for the patient, Subretinal Implants would be the best option, simply on account of appearance and convenience. Personally, I would not wan't to walk around with a camera on my head and wires running from the camera to my eye. So, at the moment, I feel that Epiretinal implant are more plausible, but in the future Subretinal Implants will be most desired.
