Advice on aftercare after eye removal

Hello

After 12 months of eye issues due to cat flu and her eye getting very high in pressure and losing vision and not being able to be stabilised with drops, the decision has been made to remove my little friend’s eye.
She’s just over one.
The poor thing has been dealing with this her whole life and is now on 3-4 drops a days and HATES THEM. She gets so stressed.

In a couple weeks we will have her eye removed.

We have been told that if everything goes smoothly she’ll have the eye removed in the morning and then come home that night.
We have another cat who’s more than double her size and then love to play together.

What’s aftercare likely to look like?

Should we seperate the cats?
If so, for how long?

Is there anything I can do or by to help her get comfortable and heal faster?

Thank you xx
