This post-approval study is being implemented to monitor the use of Argus II System in a
larger US population than available within pre-approval studies. An attempt will be made to
include all eligible and willing subjects implanted with Argus II System in the United
States.

Safety data will be monitored to ensure continued acceptability of risks to study subjects.
The utility (i.e. visual function and functional vision) and reliability of Argus II System
will also be evaluated.

There is no study hypothesis.

Inclusion Criteria:

- Are adults, age 25 year or older;

- Have severe to profound retinitis pigmentosa;

- Bare light or no light perception in both eyes; if the patient has no residual light
perception, then evidence of intact inner layer retina function must be confirmed;

- Have previous history of useful form vision.

- Aphakic or pseudophakic. (If the patient is phakic prior to implant, the natural lens
will be removed during the implant procedure.)

- Patients who are willing and able to receive the recommended post-implant clinical
follow-up, device fitting, and visual rehabilitation;

- Have consented to the implantation of an Argus II Retinal Prosthesis and subsequently
consent to participate in this study;

- At the time of the Baseline Visit, do not suffer from non-ophthalmic serious adverse
events (e.g. myocardial infarction, etc.) and

Exclusion Criteria:

- Ocular diseases or conditions that could prevent Argus II System from working (e.g.
optic nerve disease, central retinal artery or vein occlusion, history of retinal
detachment, trauma, severe strabismus);

- Ocular structures or conditions that could prevent the successful implantation of the
Argus II Implant or adequate healing from surgery (e.g. extremely thin conjunctiva,
axial length <20.5 mm or >26 mm, corneal ulcers, etc.);

- Ocular diseases or conditions (other than cataracts) that prevent adequate
visualization of the inner structures of the eye (e.g. corneal opacity, etc.);

- Inability to tolerate general anesthesia or the recommended antibiotic and steroid
regimen associated with the implantation surgery;

- Metallic or active implantable device(s) (e.g. cochlear implant) in the head;

- Pre-disposition to eye rubbing;

- Any disease or condition that prevents understanding or communication of informed
consent, study demands, and testing protocols, including:

- cognitive decline including diagnosed forms of dementia and/or progressive
neurologic disease,

- psychiatric disease including diagnosed forms of depression;

- does not speak a principal language associated with the region, and

- deafness;

- Pregnant or wish to become pregnant during the course of the study;

- Participating in another investigational drug or device study that may conflict with
the objectives, follow-up or testing of this study;

- Conditions likely to limit life to less than 1 year from the time of inclusion.
