What holds the new lens in place after cataract surgery?

I am a 64 year old female. I want to know what holds the new lens in place after cataract surgery?

Lenses are flexible and compress and expand into the space they are placed and then develop adhesions which maintain them.

The lenticular capsule and the zonules are holding the haptics of the IOL.
The whole complex is being held by ciliary muscles.

The lens goes into the same capsular sac the cataract was in and the sac wraps around it and scars down.
