[5]: 18 Among the thirty subjects in the clinical trial, there were nine serious adverse events recorded, including lower than normal intraocular pressure, erosion of the conjunctiva, reopening of the surgical wound, inflammation inside the eye, and retinal detachments.

This allows visual detection of edges of large areas of high contrast, such as door frames and sidewalks, to give the individual the capability to navigate in their environment more safely.

[4][14][15] The Argus II was initially available at a limited number of clinics in France, Germany, Italy, the Netherlands, the United Kingdom and Saudi Arabia, at an EU market price of US$115,000.
