Well on the face of it it seems unreasonable of them but depends on many things.
What sort of eye surgery? Are you someone that needs lots of attention and reassurance or do you usually not mention anything about healthcare and this was a one off you were particularly concerned about? Are they aware of all the details around it, did it involve general anaesthetic? Do you have a partner who was there with you looking after you? Did they know that? Are they busy with very young children, careers with back to back meetings. Was the operation a couple of hours ago, a couple of days, or a couple of weeks ago? Are they usually uncaring or is this out of character, was there a misunderstanding of when it was and what it was. Are you very demanding? Are they exhausted at being at your bec and call. Are they lazy selfish shits? Have you had a falling out? Do you usually speak daily/weekly? Are you feeling unusually low?
I mean, how can any of us possibly comment on this without a million more details.
I do hope you are ok and it wasn't too horrible.
