Since it isn’t a med device listed with the FDA then it hasn’t been subjected to sterilization coming out of the box nor is it likely to be able to be sterilized by the hospital since most of them use only steam sterilization and this being commercial electronics is likely not sealed sufficiently and would likely require x-ray sterilization. (Ethelyne Oxide would likely oxidize the electronics and is unavailable at any hospitals I know of anyway).
Note: Apple isn’t claiming it as a med device and hospitals have a lot of leeway in what they use as they don’t fall under the FDA.
It’s not touching the patient. It’s really just a monitor. A very small monitor “mounted” on the surgeon. Which have been in operating rooms for years. And I doubt regular glasses go through the sterilization you outline either.
It does not need “sterilized.”
Surgeons wear lights, and magnification all the time that is not sterile. Those are cleaned. The same cleaning would be good enough on the Apple device.
The resolution and cameras are amazing on it. While using it they can always remove it if they feel it is not working for their purpose. I think it is worth experimenting with the device and their surgical common and uncommon sense.
