Which Of My Patients Might Benefit From Argus II?

Argus II is currently approved and intended for use in patients with severe to profound retinitis pigmentosa (RP) who meet the following criteria:

  • Adults, age 25 years or older
  • 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.)
  • 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.

The Argus II is intended to be implanted in a single eye, typically the worse-seeing eye.
