Subretinal Implants

Subretinal Implants

Dennis Xuan

Subretinal Implants are placed behind the retina and act as closely as possible to normal, healthy retinas. The subretinal implants mimic a normal retina’s ability to take in light and converts the information into electrical signals that are sent to the rest of the eye for processing. After that the information is sent down the optic nerve and acts in exactly the same way as a normal eye from then on.

The subretinal approach is also more preferable than Epiretinal since it has more direct approach to the problem physically. Instead of stimulating the nerve cells dealing with vision the subretinal approach just mimics the function of a damaged retina. Structurally it is also preferable since it is fully implanted and there are no dangly wires around.

So since the Subretinal approach is the most simple structurally and fixes the problem in the simplest way I believe that it will probably be the most promising eye implant for the future.
