Could you replace your eye with a camera?

I think that the focus issue could certainly be fixed, arguably the focusing system already works fine the problem is that it is the camera which is choosing what to focus on and it's choice may or may not agree with your choice when the two conflict it looks bad. But in theory this could be fixed by having the device take it's cues where the focus should be from the user this would certainly be something quite reasonable in theory for a bionic eye since it could be made to monitor the signals from the brain to the eye either directly by connecting to the nerves or even indirectly using eye tracking and perhaps also scanning the eyeball shape using a low power IR laser, ultrasound or whatever.
