Factual error: Simon Phoenix uses the warden's removed eye to escape from the cryoprison. The eye is on a pen, and since the retina includes the back portion of the eye, the pen's nib would have not only destroyed the shape of the retina, but blocked the scanner from reading the complete retina as well. There's no way the retinal scanner would have let him pass. (00:18:45)
Suggested correction: This is a piece of future technology imagined from 1993. It can work; however, it can as long as it is consistent in the world of the film.
