covers the white part of
the eye and the inner
surface of the eyelids.
(See Figure 1)

in your eye so that the
Argus II Implant can be
placed in your eye.
Iris
The iris is the round
structure in the eye that
gives the eye color. For
example, blue-eyed
people have a blue iris
while brown-eyed people
have a brown iris. The
center of the iris is an
opening called the pupil.
The iris controls the size
of the pupil when it
reacts to the amount of
light that is present.
(See Figure 1)
Radio
Frequency (RF)
Any electromagnetic
frequency within the

communication.
