What could the side effects be for long-term Cryosleep?

I'm writing a story about someone who is going to be frozen in cryo for about 450 years. He's frozen in 2120, so the technology is certainly well-developed in his time. I'm thinking maybe the cryo pod he was put in wasn't built very well, or maybe 450 years is a bit long to be frozen and not the length of time his pod was meant to work for.

I'm wondering what physical and mental side effects he could suffer from, either from being frozen for so many years, or from a not-so-great cryo pod, or both.

I was also wondering if it's at all possible that he could specifically suffer from some kind of change in his eye color.

I've looked at sources online, read about how Fallout and Halo and how some movies handle cryo, but I couldn't find anything about side effects except confusion and nausea.

Any help would be appreciated :)
