Store the VPU,
glasses, and batteries in the travel case provided by
Second Sight. The travel case is designed to protect the
equipment. Do not place anything on top of the glasses
or VPU.
Expected Failure Time and Its Effect on You
The Argus II Implant is designed to operate for at least five
years. Laboratory testing has demonstrated that the implant
should last that long. Insufficient time has elapsed in actual
clinical use to provide proof that the device will function
properly for more than five years, but performance to date
and laboratory testing suggest that it will.
One way the implant could fail is that it could stop
responding to signals from the glasses and stop stimulating.
If it fails in this manner, you should not experience any
harmful effects. In such a rare case, the implant may be
removed and replaced if possible and desired.
The VPU and glasses are much more susceptible to
handling and breakage than the implant. This equipment
may be replaced if necessary.
Rechargeable battery life is described in
“Battery Life”, page
71 of this chapter.
